[0003] Water is essential for cooking, drinking, personal hygiene, and many more aspects of human, animal, and plant life. However, fresh and safe water sources are limited or unavailable in many remote and rural locations around the world, and many people’s lives are negatively impacted by lack of access to water. For example, people may have to travel great distances or endure hardships to obtain usable water. Some people may suffer from ill health and possibly even die due to lack of clean water. Also, lack of access to clean water may have a disproportionately negative impact on women and children.

[0004] Organizations have attempted to reduce water access issues and / or provide alternative sources of water to people in remote and rural locations. For example, fresh water may be shipped to the locations and stored. In addition or alternatively, filter systems may be provided for the remote locations. However, these solutions can be costly and difficult if not impossible to institute for many locations.

[0005] Therefore, there is a need for a system and a method for supplying clean water that is low cost and able to be provided to remote and rural locations around the world.BRIEF DESCRIPTION

[0023] FIG. 1 is a schematic diagram of a system 100 for filtering and / or storing water. Suitably, as described further later, the system 100 is modular and transportable as a single unit. For example, the system 100 can be easily modified to replace, add, or omit components. In particular, pipes, tanks, valves, etc. of the system 100 are connected together by commoncouplings or quick-connect couplings. Tn addition, the components may be standard sizes and types to facilitate easy repair and replacement. Also, the system 100 is constructed to be self- contained. As a result, the system 100 is simple to assemble, operate, transport, and maintain. Moreover, the system 100 is suitable for use in remote or difficult to access locations where resources and clean water are lacking.

[0024] In the example, the system 100 includes at least one inlet 102 arranged to receive water, at least one outlet 104 arranged to dispense filtered water, a water line 106 fluidly connecting the inlet and the outlet, and at least one filter 108 arranged along the water line to filter water flowing through the water line. For example, the inlet 102 is connected to an external water source (not shown). The external water source may be a municipal or local water supply, a pipe, a tank, another filtration system 100, a rainwater collection system, and / or any other suitable water source. The outlet 104 may be connected to a plumping system, a tank, a spigot, another filtration system 100, and / or any other water use system. In some embodiments, the inlet 102 and / or the outlet 104 may include a manifold and be configured to regulate connections to more than one external system.

[0025] The water line 106 may include any suitable conduits. For example, the water line 106 may comprise PVC pipes which are readily available and simplify construction of the system 100. Also, the PVC material is safe for carrying potable water and does not introduce contaminants into the water. The water line 106 includes quick connect or standardized couplings to facilitate connection with components. In some embodiments, at least a portion of the water line 106 is flexible and able to move during assembly or operation. For example, the water line 106 may include flexible tubing to extend between components of different sizes and shapes and facilitate the form factor of the system 100. As a result, the water line 106 facilitates the system 100 being modular and facilitates simple construction and maintenance of the system. In other embodiments, the water line 106 is constructed of metal, plastic, and / or any suitable material.

[0026] In the example, the system 100 includes a bypass line 110, a bypass valve 112, an inlet control valve 114, and an outlet control valve 116. The bypass line 110 and the bypass valve 112 direct water to flow from the inlet 102 directly to the outlet 104. For example, the inlet control valve 114 and the outlet control valve 116 are switched to a close position, and thebypass valve 1 12 is opened to facilitate water flowing from the inlet 102 directly to the outlet 104 without flowing through the water line 106 and the fdters 108. Accordingly, the bypass line 110 and the bypass valve 112 facilitate use of the water from the external water source without disconnecting the system 100. For example, the bypass line 110 may be utilized to access water from the external water source when the system is being serviced or repaired and / or is otherwise out of commission. In other embodiments, the bypass line 110 may bypass only a portion of the system such as at least some of filters 108 to facilitate use of unfiltered water when filtered water is unnecessary and thereby prolong the service life of the filters.

[0027] In addition, the system 100 includes a pump 118 configured to direct water through the water line 106. The pump 118 is connected between the inlet 102 and the outlet 104 and is configured to direct water from the inlet 102 through the water line 106 and toward the outlet 104. In addition, the pump 118 directs the water through the filters 108, as described further below. The pump 118 may be any suitable pump. The pump 118 is connected to a controller 120. In the example, the controller 120 includes a pump relay box 122 which is connected to a power source and regulates power supplied to the pump 118 to control operation of the pump. In addition, the controller 120 is connected to one or more sensors described later and the controller controls operation of the pump 118 based on feedback from the sensors.

[0028] Optionally, the system 100 includes a water storage tank 124. The water storage tank 124 is connected to the water level automation chamber 126 at the base. The water storage tank 124 is downstream of the inlet 102. The water storage tank 124 may be any suitable size and is configured to receive and store water that flows through the system 100. In the example, the water level automation chamber 126 is connected to the water storage tank 124 at a single port 142 such that the single port acts as an inlet and an outlet for the water storage tank 124. In some embodiments, the water storage tank 124 is omitted. For example, because the system 100 is modular, the water storage tank 124 may easily be disconnected and / or the water storage tank may be replaced without affecting at least some functionality of the system.

[0029] The system 100 includes a water level automation chamber 126 arranged along the water line 106 between the water storage tank 124 and the inlet 102 to regulate a level of water in the system and the water storage tank. The water level automation chamber 126 defines a cavity 128 sized to receive water. For example, the water level automation chamber 126 maybe sized to receive at least 1 gallon of water, at least 10 gallons of water, or at least 100 gallons of water.

[0030] The water level automation chamber 126 includes an inlet 130 that is connected to the water line 106 to receive the water. For example, the inlet 130 includes a pipe 132 positioned within the cavity 128 of the water level automation chamber 126. The pipe 132 extends downward from a top of the water level automation chamber 126 towards a bottom of the water level automation chamber 126. An end 134 of the pipe 132 is positioned at a height within the cavity 128 of the water level automation chamber 126 that corresponds to a desired minimum water level of the water in the water level automation chamber 126.

[0031] A valve 136 is connected to the end 134 of the pipe 132 and regulates water flow through the inlet 130 and into the cavity 128 of the water level automation chamber 126. For example, the valve 136 is open and water is allowed to flow into the cavity 128 of the water level automation chamber 126 when the water level is below the desired minimum water level. The valve 136 is closed when the water level is at or above the desired minimum water level.

[0032] In the example shown in FIG. 1, the valve 136 is a submersible float valve. For example, the valve 136 includes a float that floats in the water and moves between a first lower position to a second higher position. The float actuates the valve 136 between the open and closed position when the float moves between the first and second positions. The first lower position corresponds to water being below the desired minimum water level. The second higher position corresponds to the water being at or above the desired minimum water level. In other examples, the valve 136 is an electronic valve and / or a mechanically actuated valve.

[0033] The water level automation chamber 126 has an outlet 138 connected to the water storage tank 124 and arranged to supply water to the water storage tank. The water level automation chamber 126 and the water storage tank 124 are positioned such that a water level in the water level automation chamber 126 is equal to a water level of water in the water storage tank 124, as seen in FIGs. 4 and 5. For example, the water line 106 is connected to bottoms of the water storage tank 124 and the water level automation chamber 126 such that water is allowed to flow openly between the water storage tank and the water level automation chamber when a control valve 140 is open. In addition, the water storage tank 124 and the water levelautomation chamber 126 are positioned at the same elevation. As a result, water is able to flow between the water storage tank 124 and the water level automation chamber 126 and the water levels will be equalized due to both the water storage tank and the water level automation chamber having the same pressure head. For example, the water storage tank 124 will have a water level equal to the desired minimum water level when the water in the water level automation chamber 126 is at the minimum desired level. The desired minimum water level of the water in the water storage tank 124 is aligned with the desired minimum water level of the water in the water level automation chamber 126. The water storage tank 124 and the water level automation chamber 126 are the same size and contain equal amounts of water when the water levels are the same. In other examples, the water storage tank 124 and the water level automation chamber 126 are different sizes and contain different amounts of water when the water levels are the same.

[0034] In the example, the system 100 includes an outlet control valve 140 configured to regulate flow of water out of the water level automation chamber 126 through the outlet 138. The outlet control valve 140 may be positioned between an open position and a closed position. In some embodiments, the water storage tank 124 is omitted. In such embodiments, the outlet 138 and the control valve 140 may be omitted or used for another purpose such as to connect to an auxiliary system 100 or as a drain for the water level automation chamber 126.

[0035] The system 100 includes a water intake 143 positioned in the water level automation chamber 126 and arranged to selectively withdraw water from the water level automation chamber. For example, the pump 118 is arranged to cause water to flow into the intake 143 and through the water line 106. In the example shown in FIGs. 4 and 5, the intake 143 is flexible and arranged to float at or near the surface of the water in the water level automation chamber 126. Accordingly, the intake 143 is arranged to withdraw water that is farthest from any sediment that may settle at a bottom of the water level automation chamber 126.

[0036] A sensor 144 is positioned within the water level automation chamber 126 to measure the water level within the water level automation chamber. For example, the sensor 144 includes an electronic float valve that is configured to detect if water is above or below aminimum operation level. The electronic float valve includes a float that moves based on the water level and is connected to a switch that transitions between an open position and a close position based on movement of the float. The sensor 144 generates an electronic signal when the switch is in a close position and completes an electric circuit. The switch may be in a close position when the water level is above or below the minimum operation level. The sensor 144 provides the signal relating to the water level to the controller 120. For example, the sensor 144 provides a signal to turn off the pump 118 if the water level in the water level automation chamber 126 is below the minimum operation level.

[0037] The system 100 includes one or more of the fdters 108 arranged along the water line 106 between the inlet 102 and the outlet 104 to filter water flowing through the system. For example, a first filter 146 is disposed between the inlet 102 and the water level automation chamber 126. Also, in the example, a second filter 148 and a third filter 150 are disposed between the water level automation chamber 126 and the outlet 104. The first filter 146 provides initial filtration of the water before the water is stored in the water level automation chamber 126. For example, the first filter 146 is a sediment filter. In some embodiments, the first filter 146 is omitted based on the quality of input water. In some embodiments, additional filters 108 are positioned upstream of the water level automation chamber 126. In other embodiments, none of the filters 108 are positioned upstream of the water level automation chamber 126.

[0038] The second filter 148 and the third filter 150 are configured to remove contaminants from the water. In other embodiments, the system 100 may include more or less of the filters 108. For example, in some embodiments, the system 100 includes microbial filters and / or UV sterilization filters connected to a drinking water system and configured to provide fine filtration of the water such that the water is suitable as drinking water.

[0039] In the example, the system 100 includes a rainwater chamber 152 that is connected to the water level automation chamber 126 and defines a cavity to receive water. The rainwater chamber 152 is arranged as a first flush system in which sediments, contaminants, and debris are allowed to settle out of the water. For example, the rainwater chamber 152 includes an inlet 154 and an outlet 156. The outlet 156 is positioned at the top of the rainwater chamber 152 away from the bottom of the rainwater chamber. As a result, sediments and other materials are allowed to settle to the bottom of the rainwater chamber 152. Water is removed from the topof the rainwater chamber 152 where the water is cleaner than the water near the sediment at the bottom of the rainwater chamber 152. The rainwater chamber 152 includes a flush valve 158 and an outlet 160 positioned at the bottom of the rainwater chamber to facilitate removing dirty water and materials from the rainwater chamber.

[0040] The rainwater chamber 152 may have a water level that is different from the water levels of the water storage tank 124 and the water level automation chamber 126. For example, the rainwater chamber 152 may fdl with water and contain water within the rainwater chamber until the water reaches the level of the outlet 156 positioned at the top of the rainwater chamber 152. When the water reaches the height of the outlet 156, the water flows out of the rainwater chamber 152 through the outlet and into the water level automation chamber 126. The water flows through the outlet 156 into the water level automation chamber 126 until the water level automation chamber and the water storage tank 124 are full or the water level of the water level automation chamber and the water storage tank 124 is at the level of the water in the rainwater chamber 152. Accordingly, the rainwater chamber 152 has a different water level from the water level automation chamber 126 and the water storage tank 124 unless the water levels in the water level automation chamber, the water storage tank, and the rainwater chamber are at or above the level of the outlet 156.

[0041] The water storage tank 124, the water level automation chamber 126, and the rainwater chamber 152 are molded plastic. As a result, the water storage tank 124, the water level automation chamber 126, and the rainwater chamber 152 facilitate the system 100 being modular and facilitate simple construction and maintenance of the system. In other embodiments, the water storage tank 124, the water level automation chamber 126, and / or the rainwater chamber 152 are constructed of metal, plastic, and / or any suitable material.

[0042] In addition, the system 100 includes sensors 162 arranged to measure water flow through the system 100. In the example, the sensors 162 are flow meters and are arranged to measure water flow input into the system 100 from the exterior source and water flow output from the system. For example, a first one of the sensors 162 is arranged between the inlet 102 and the water level automation chamber 126 to measure water flow input through the inlet 102.A second one of the sensors 162 is arranged between the pump 118 and the outlet 104 to measure water flow output through the outlet 104.

[0043] The controller 120 receives information from the sensors 162 and determines operating parameters of the system 100 based on the information. For example, the controller 120 calculates rainwater provided by the system 100 based on information received from the sensors 162. The controller 120 subtracts the water input reading received from the sensor 162 positioned at the inlet 102 from the water output reading received from the sensor 162 positioned at the outlet 104. The difference between the readings is the rainwater provided by the system 100. In other embodiments, the system 100 includes a sensor 162 arranged to directly measure the rainwater flowing into and / or through the system and / or any other suitable sensor 162.

[0044] Optionally, the controller 120 is communicatively coupled to and configured to operate components of the system 100. For example, the controller 120 is communicatively coupled to and / or configured to operate the pump 118, the sensors 162, the bypass valve 112, the inlet control valve 114, the outlet control valve 116, and / or the valve 136. In some embodiments, the controller 120 comprises only a pump relay system connected to the sensor 144 and facilitates the system 100 operating in rural, underdeveloped regions.

[0045] Optionally, the controller 120 may include a processor and a memory. The controller 120 may be located entirely within the pump relay box 122 and / or incorporated onboard components of the system 100. Also, the controller 120 may be located at least partly offboard the physical components of the system 100. For example, the controller 120 may include a user interface that is accessible on a computer or mobile device.

[0046] Referring to FIG. 1, to assemble the system 100, the water level automation chamber 126 is connected to the water line 106 such that the water line 106 fluidly connects the water level automation chamber to the inlet 102 and the outlet 104. The fdters 108 are connected along the water line 106 and arranged to filter water flowing through the water line between the water level automation chamber 126 and the inlet 102 or the outlet 104. One or more additional components may be connected to the water line 106. For example, the pump 118 is connected along the water line 106 to pump water from the water level automation chamber 126 to the outlet 104.

[0047] The inlet 102, the water line 106, the outlet 104, the water level automation chamber 126, the filters 108, the pump 118, and / or other components are mounted to a frame. The frame facilitates the components being at a correct location in relation to the other components and facilitates operation of the system. In addition, the frame facilitates the system 100 being modular and simpler to ship and assemble in remote locations. The components mounted to the frame may be at least partly enclosed in a housing.

[0048] FIG. 2 is a schematic diagram of the system 100, illustrating flow of water from an external water source into and through the system. The inlet 102 of the system 100 may be coupled to the external water source such that water may enter the system through the inlet. When the system 100 is receiving water from the external water source, water flows into the inlet 102, through the water line 106, past the bypass valve 112, and to the first filter 146. The first filter 146 removes, for example, sediments from the water. The water travels from the first filter 146 and through the inlet 130 into the water level automation chamber 126.

[0049] The water may be withdrawn from the water level automation chamber 126 via the intake 143. For example, the pump 118 is connected to the water line 106 downstream of the water level automation chamber 126 and causes water to flow into the intake 143 when the pump is powered on. If the sensor 144 detects that the water level within the water level automation chamber 126 is below the minimum operating level, the sensor 144 provides a signal to stop operation of the pump 118 and therefore water is not drawn into the intake 143 until the water reaches the minimum operating level.

[0050] After being withdrawn from the water level automation chamber 126, the water flows from the pump 118 to the second filter 148 and the third filter 150. The second filter 148 and the third filter 150 remove contaminants from the water. In some embodiments, the second filter 148 and / or the third filter 150 may be positioned upstream of the pump 118. The filtered water flows from the third filter 150 to the outlet 104 where the water may be discharged from the system 100. For example, the filtered water may be discharged for individual consumption, into a facility water supply, and / or into pipes or containers.

[0051] FIG. 3 is a schematic diagram of the system of FIG. 1, illustrating flow of rainwater into the system. The system 100 is configured to receive and process the rainwater.For example, a rainwater collection system may be coupled to the inlet 154 of the rainwater chamber 152 such that rainwater flows into the rainwater chamber through the inlet. As the rainwater flows into the rainwater chamber 152, sediments and other materials are allowed to settle to the bottom of the rainwater chamber 152. When the rainwater chamber 152 is full, the water flows from the rainwater chamber 152 and into the water level automation chamber 126. In some embodiments, the rainwater chamber 152 is omitted and the rainwater is provided directly into the water level automation chamber 126.

[0052] As seen in FIG. 4, the system 100 is configured to receive and utilize water from the external water source when the water level in the water level automation chamber 126 is below a target level 131. For example, when the water level is below the target level 131, the valve 136 is in an open position and the water from the external water supply is allowed to flow into the water level automation chamber 126 until the water level reaches the target level 131, which is above the minimum operating water level. When the water level in the water level automation chamber 126 is above the minimum operating water level, the pump 118 is activated and able to cause water to flow into the intake 143 and through the water line 106. As a result, the system 100 is able to operate and provide filtered water even when the rainwater chamber 152 is not full.

[0053] Referring to FIG. 5, the system 100 may operate using rainwater. For example, the rainwater flows from the rainwater chamber 152 into the water level automation chamber 126 when the rainwater chamber 152 is full. Some water flows toward the water storage tank 124 to raise the level of the water storage tank equal to the level of water in the water level automation chamber 126. If enough rainwater is received, the rainwater flows into the water level automation chamber 126 to cause the water level to raise above the target level and to fdl up the chambers. Flow of water from the external water source into the water level automation chamber 126 is stopped when the water level is above the target level. The pump 118 is powered on and the water is withdrawn from the water level automation chamber through the intake 143. The water flows from the pump 118 to the second filter 148 and the third filter 150. The filtered water then flows to the outlet 104 where the water may be discharged from the system 100.

[0054] FIG. 6 is a schematic diagram of an example rainwater system 200. The rainwater system 200 may connected to or incorporated into the system 100 shown in FIG. 1 (e.g., in place of the rainwater chamber 152). Alternatively, the rainwater system 200 may be used as a standalone system. The rainwater system 200 is used to process rainwater or other fluids. The rainwater system 200 may be connected to an existing rainwater collection or diversion system such as a gutter system connected to a roof of a structure.

[0055] The rainwater system 200 includes an inlet 202. The inlet 202 receives rainwater delivered to the rainwater system 200. For example, the inlet 202 may be connected to a pipe or downspout downstream of an existing rainwater collection or diversion system. In the example illustrated in FIG. 6, the rainwater system 200 includes a single inlet 202. In other examples, the rainwater system 200 includes two or more inlets 202 to facilitate the rainwater system 200 connecting to multiple discharge points of the same or different systems. Also, the arrangement of the inlet 202 or the multiple inlets 202 facilitates the rainwater system 200 being compatible with different systems and simplifies installation of the rainwater system.

[0056] As seen in FIG. 6, the inlet 202 includes a funnel shaped body 203 that defines an opening 205. The funnel shaped body 203 is wider at the opening 205 and tapers to a smaller width at an end of the inlet 202 that is connected to a pipe 207. The inlet 202 facilitates water being received into the rainwater system 200 and being directed through the system.

[0057] Also, the rainwater system 200 includes a rainwater chamber 204 connected downstream of the inlet 202 and defining a cavity to receive water that enters the rainwater system through the inlet 202. The rainwater chamber 204 may be sized to receive at least 10 gallons of water, at least 20 gallons of water, or at least 100 gallons of water. The rainwater chamber 204 is a rectangular cuboid shape. In addition, the rainwater chamber 204 is molded plastic.

[0058] A first overflow outlet 210 is positioned downstream of the inlet 202 and defines an opening 209 in fluid communication with the cavity of the rainwater chamber 204. The first overflow outlet 210 is connected to the pipe 207 between the inlet 202 and the rainwater chamber 204. The first overflow outlet 210 extends at an angle relative to the pipe 207 and the inlet 202 such that the opening 209 is upstream of the connection of the first overflow outlet 210to the pipe 207. Water that flows into the inlet 202 flows past the first overflow outlet 210 and into the rainwater chamber 204 unless the rainwater chamber 204 is full. If the rainwater chamber 204 is full, the water flows into the first overflow outlet 210 and exits the rainwater system 200 through the opening 209.

[0059] The pipe 207 extends from the inlet 202 into the cavity of the rainwater chamber 204 and directs water into the cavity of the rainwater chamber. In the example, the pipe 207 extends from the inlet 202 at the top of the rainwater chamber 204 to the bottom of the rainwater chamber such that water that flows into the rainwater chamber 204 is directed towards the bottom of the rainwater chamber 204. In addition, the pipe 207 includes a bend near the bottom of the rainwater chamber 204 such that water exits the pipe 207 in a generally upward direction and facilitates settlement of any materials in the water to the bottom of the rainwater chamber 204.

[0060] Also, a flush drain 212 is connected to the rainwater chamber 204. The flush drain 212 is located at the bottom of the rainwater chamber 204. The flush drain 212 is positionable between an open position and a closed position. In the open position, the water in the rainwater chamber 204 is able to exit the rainwater chamber 204 through the flush drain 212. In the closed position, the flush drain 212 prevents the water from exiting the rainwater chamber 204 through the flush drain 212.

[0061] In addition, the rainwater system 200 includes a water level automation chamber 206. The water level automation chamber 206 is connected downstream of the rainwater chamber 204 by a connection line 208. For example, the connection line 208 extends between the water level automation chamber 206 and the rainwater chamber 204 at the tops of the water level automation chamber and the rainwater chamber. Water can flow through the connection line 208 and between the water level automation chamber 206 and the rainwater chamber 204 when the water level within the rainwater chamber 204 reaches the connection line 208.

[0062] The water level automation chamber 206 defines a cavity to receive water and is configured to regulate the level of the water that is maintained in the rainwater system 200. The water level automation chamber 206 may be sized to receive at least 10 gallons of water, at least 20 gallons of water, or at least 100 gallons of water. The water level automation chamber 206 isa rectangular cuboid shape. In addition, the water level automation chamber 206 is molded plastic.

[0063] The rainwater system 200 includes an intake 214. The intake 214 is fluidly connected to an outlet 215 for water to exit the rainwater system 200 and / or be directed toward a system connected to the rainwater system 200. The intake 214 is in the cavity of the water level automation chamber 206. In other embodiments, the rainwater system 200 includes an intake 214 positioned within the rainwater chamber 204. In the example, the intake 214 is positioned includes a float 217 and is flexible to facilitate the intake 214 remaining near the surface of the water in the water level automation chamber 206.

[0064] A second overflow outlet 218 is connected to the water level automation chamber 206 in fluid communication with the cavity of the water level automation chamber 206. The second overflow outlet 218 is located at the top of the water level automation chamber 206 and is spaced away from the connection line 208. The second overflow outlet 218 facilitates excess fluid, e.g., overflow, exiting the water level automation chamber 206, when the water level automation chamber 206 is full.

[0065] An optional water storage tank connection 216 is provided for connecting the rainwater system 200 to a water storage tank such as the water storage tank 124 shown in FIG. 1 . The water storage tank connection 216 is connected to the water level automation chamber 206.

[0066] An optional external water supply inlet 220 is provided for connecting the rainwater system 200 to an external water supply. The external water supply inlet 220 extends into the water level automation chamber 206 and is arranged to dispense water into the water level automation chamber 206 when the external water supply is activated. Optionally, the rainwater system 200 includes a sensor and / or valve 222 connected to the external water supply inlet 220 and configured to open / close the external water supply inlet 220 based on the level of water in the water level automation chamber 206. In some embodiments, the external water supply inlet 220 is connected to the rainwater chamber 204 or is omitted.

[0067] During operation, rainwater flows through the inlet 202 and into the rainwater chamber 204 through the pipe 207. The pipe 207 extends from the top of the rainwater chamber204 to the bottom of the rainwater chamber such that water flows first into the bottom of the rainwater chamber. Sediment and materials settle to the bottom of the rainwater chamber. The first overflow outlet 210 is connected to the inlet 202 such that water can flow out of the first overflow outlet 210 if the rainwater chamber 204 is full.

[0068] Rainwater flows from the rainwater chamber 204 through the connection line 208 and into the water level automation chamber 206. From the water level automation chamber 206, the water may travel through the intake 214 to a filtration system, through the optional water storage tank connection 216, and / or through the second overflow outlet 218.

[0069] In the example, the rainwater chamber 204 and the water level automation chamber 206 are compact in shape and size. For example, the rainwater chamber 204 and the water level automation chamber 206 are rectangular cuboids. In addition, the rainwater chamber 204 and the water level automation chamber 206 include identical tanks. In some embodiments, the chambers 204, 206 are constructed from a series of correspondingly shaped containers, e.g., containers having curved walls, that mate together. Accordingly, the rainwater chamber 204 and the water level automation chamber 206 are modular and easily transported and replaced.

[0070] FIGs. 7 and 8 illustrate an example of a system 300 for filtering and storing water. The system 300 is similar to the system 100. For example, the system 300 includes the inlet 102, the outlet 104, the water lines 106, the pump 118, the controller 120, the water level automation chamber 126, the rainwater chamber 152, the filters 108, and the sensors 162.

[0071] In addition, the system 300 includes a drinking water discharge 302 and a frame 304. The frame 304 supports components of the system 300 and facilitates transportation and set up of the system 300. For example, the frame 304 provides supports for the components of the system 300 to be mounted to during assembly and transport. Specifically, the frame 304 provides support for, for example, the inlet 102, the outlet 104, the water lines 106, the pump 118, the controller 120, the water level automation chamber 126, the rainwater chamber 152, the filters 108, and the sensors 162. The components are supported in a compact, e.g., rectangular cuboid, form factor while still providing access to operate and maintain the system 300. The frame 304 facilitates the system 300 being modular because the frame 304 provides space for additional or different components such as filters 108. In addition, the frame 304 is constructedfrom members welded or otherwise permanently joined together or integrally formed as a single unitary piece.

[0072] In some embodiments, the frame 304 includes one or more panels attached to the frame supports and arranged to cover sides of the frame 304. The panels may form a housing. Accordingly, the frame 304 with the housing enclose the system 300 and protect the system from the environment and tampering by unauthorized personnel.

[0073] FIGs. 9 and 10 illustrates an example of a portion of a system 400 for filtering and storing water. The system 400 is connected to a rainwater collection system, e.g., gutters and downspouts, on a structure. The system 400 is similar to the systems 100, 300. For example, the system 400 includes the inlet 102, the outlet 104, the water lines 106, the pump 118, the controller 120, the water level automation chamber 126, the fdters 108, and the sensors 162 of the system 100.

[0074] In addition, the system 400 includes a housing 402 enclosing the inlet 102, the outlet 104, the water lines 106, the pump 118, the controller 120, the filters 108, and the sensors 162. The housing 402 includes a frame 404 and panels 406 secured to the frame. The panels 406 form a roof, a floor, and sidewalls of the housing 402 and completely enclose the components of the system 400. At least one of the panels 406 is selectively movable to provide access to an interior of the housing 402. One or more of the panels 406 may include vents to facilitate airflow into the interior of the housing 402 for temperature and humidity regulation. In addition, the housing 402 includes supports or shelves 408 for mounting components such as the pump 118, the filters 108, and the controller 120 within the interior of the housing.

[0075] Suitably, the system 400 is modular and easily transportable. For example, the system 400 is sized and shaped such that a plurality of the systems 400 fit within a standard shipping container. For example, at least forty of the systems 400 may be arranged in a standard shipping container.

[0076] FIG. 11 is a schematic diagram of a system 500 for filtering and storing water. The system 500 is similar to the system 100 except as described. For example, the system 500 includes an inlet 502, an outlet 504, a water line 506, filters 508, a bypass line 510, a bypassvalve 512, an inlet control valve 514, a pump 518, a controller 520, and an optional water storage tank 524 that are similar to the inlet 102, the outlet 104, the water line 106, the filters 108, the bypass line 110, the bypass valve 112, the inlet control valve 114, the pump 118, the controller 120, the pump relay box 122, and the optional water storage tank 124 of the system 100 (shown in FIG. 1).

[0077] As seen in FIG. 11, the system 500 includes a water level automation chamber 526 arranged along the water line 506 between the water storage tank 524 and the inlet 502 to regulate a level of water in the system and the water storage tank. The water level automation chamber 526 defines a cavity 528 sized to receive water. The water level automation chamber 526 includes an inlet 530 that is connected to the water line 106. A valve 536 is connected to the water line 506 upstream of the inlet 530 and regulates water flow through the inlet 530 and into the cavity 528 of the water level automation chamber 526. For example, the valve 536 is open and water is allowed to flow into the cavity 528 of the water level automation chamber 526 when the water level is below the desired minimum water level. The valve 536 is closed when the water level is at or above the desired minimum water level. In the example shown in FIG. 11, the valve 536 is an electronic valve.

[0078] The water level automation chamber 526 has an outlet 538 connected to the water storage tank 524 and arranged to supply water to the water storage tank. In the example, the system 500 includes an outlet control valve 540 configured to regulate flow of water into the water storage tank 524 from the water level automation chamber 526 through the outlet 538. The outlet control valve 540 may be positioned between an open position and a close position. In some embodiments, the water storage tank 524 is omitted. In such embodiments, the outlet 538 and the control valve 540 may be used for another purpose such as to connect to an auxiliary system or as a drain for the water level automation chamber 526.

[0079] The water line 506 is also connected to the outlet 538 of the water level automation chamber 526 and arranged to selectively withdraw water from the water level automation chamber. For example, the pump 518 is arranged to cause water to flow out the outlet 538 and through the water line 506 when the pump 518 is activated.

[0080] At least one sensor 544 is positioned within the water level automation chamber 526 to measure the water level within the water level automation chamber. For example, the sensors 544 include a pair of electronic switches 545 that are configured to detect if water is above or below predetermined levels. The electronic switches 545 each include a switch that transitions between an open position and a close position and completes an electric circuit based on the position of the water. For example, the switch may be in a closed position when the water level is above or below a predetermined water level. Each switch 545 generates an electronic signal when the switch is in a close position. One of the electronic switches 545 is located near a bottom of the water level automation chamber 526. The other of the electronic switches 545 is located near a top of the water level automation chamber 526. The sensors 544 provide a signal relating to the water level to the controller 520. For example, the sensors 544 provide a signal to turn off the pump 518 if the water level in the water level automation chamber 526 is below the minimum operation level. Also, the sensors 544 provide a signal to stop water from an external water source if the water level in the water level automation chamber 526 is above a predetermined level. The controller 520 controls automated valves based on the signals received from the sensors 544.

[0081] The system 500 includes one or more fdters 508 arranged along the water line 506 between the inlet 502 and the outlet 504 to fdter water flowing through the system. For example, a first filter 546 is disposed between the inlet 502 and the water level automation chamber 526. The first filter 546 provides initial filtration of the water before the water is stored in the water level automation chamber 526. Also, in the example, a second filter 548, a third filter 549, and a fourth filter 550 are disposed between the water level automation chamber 526 and the outlet 504. In addition, the system 500 includes an ultraviolet (UV) sterilization system 551. The UV sterilization system includes an ultraviolet sterilization filter and utilizes ultraviolet light to remove bacteria and microorganisms from the water. The second filter 548, the third filter 549, the fourth filter 550, and the UV sterilization system 551 are configured to remove contaminants from the water. In other embodiments, the system 500 may include more or less of the filters 508. For example, in some embodiments, the system 500 includes microbial filters and / or additional UV filters connected to a drinking water system and configured to provide fine filtration of the water such that the water is suitable as drinking water.

[0082] In the example shown in FIG. 11, the system 500 includes a rainwater chamber 552 that is connected to the water level automation chamber 526 and defines a cavity to receive water. The rainwater chamber 552 includes an inlet 554, a first outlet 556, and a second outlet 560. The first outlet 556 is positioned at the top of the rainwater chamber 552 away from the bottom of the rainwater chamber. Water is removed through the first outlet 556 at the top of the rainwater chamber 552 where the water is cleaner than the water near the sediment at the bottom of the rainwater chamber 552. The second outlet 560 is positioned at the bottom of the rainwater chamber 552 to facilitate removing dirty water and materials from the rainwater chamber. The system 500 includes an electronic actuator valve 558 positioned downstream of the second outlet 560 to regulate discharge of the materials through the second outlet and out an overflow drain 570. For example, the electronic actuator valve 558 is connected to a control panel of the controller 520 and receives a signal from the controller 520 to cause the electronic actuator valve 558 to open for a pre-determined time interval for water to drain from the rainwater chamber 552.

[0083] The water level automation chamber 526 and the rainwater chamber 552 are molded plastic and are a modular shape. For example, the water level automation chamber 526 and the rainwater chamber 552 each have repeating compartments that receive predetermined volumes of fluid and are identical to each other. The water level automation chamber 526 and the rainwater chamber 552 each may be formed to have a desired volume by selecting different numbers of the compartments. In addition, the water level automation chamber 526 and the rainwater chamber 552 are durable, simpler to transport, and can be more readily produced in regions that may not have access to complex manufacturing processes or materials.

[0084] In addition, the system 500 includes sensors 562 arranged to measure water flow through the system 500. In the example, the sensors 562 include flow meters and are arranged to measure water flow input into the system 500 from the exterior source and water flow output from the system.

[0085] The controller 520 is communicatively coupled to and configured to operate components of the system 500. For example, the controller 520 is communicatively coupled to and / or configured to operate the pump 518, the water level sensor 544, the UV sterilization system 551, the valve 536, and / or the electronic actuator valve 558. For example, the controller520 is configured to operate the pump 518 to induce water flow through the system 500. The controller 520 is configured to operate the valve 536 to facilitate water flow into the water level actuation chamber 526 when the water level is below a first predetermined level and stop the water flow into the water level actuation chamber when the water level is at or above a second predetermined level.

[0086] The system 500 includes a housing 566 at least partly enclosing the inlet 502, the outlet 504, the water line 506, the pump 518, the controller 520, the filters 508, and the sensors. For example, the housing 566 includes walls that protect the system 500 and at least one movable panel or door that provides access to the interior of the housing. The walls of the housing 566 may be metal, plastic, or any suitable material.

[0087] Also, the system 500 includes check valves 568 connected to the water line 506. For example, the check valves 568 are located between the inlet 502 and the first filter 546, between the inlet 502 and the outlet 504, between the outlet 538 and the filter 508, and between the pump 518 and the outlet 504. The check valves 568 prevent backflow in the water line 506 and facilitate fluid flow in desired directions.

[0088] FIG. 12 is a schematic diagram of the system 500, illustrating flow of water from an external water source into and through the system. The inlet 502 of the system 500 may be coupled to the external water source such that water may enter the system through the inlet. When the system 500 is receiving water from the external water source, water flows into the inlet 502, through the water line 506, past the bypass valve 512, and to the first filter 546. The first filter 546 removes, for example, sediments from the water. The water travels from the first filter 546 and through the inlet 530 into the water level automation chamber 526. The water from the external water source mixes with any rainwater within the water level automation chamber 526.

[0089] The water may be withdrawn from the water level automation chamber 526 via the outlet 538. For example, the pump 518 is connected to the water line 506 downstream of the water level automation chamber 526 and causes water to flow through the outlet 538 when the pump is powered on. If the lower sensor 544 detects that the water level within the water level automation chamber 526 is below the minimum operating level, the lower sensor 544 provides a signal to stop operation of the pump 518 and therefore water is not drawn through the outlet 538until the water reaches the minimum operating level. If the upper sensor 544 detects that the water level within the water level automation chamber 526 is at or above a predetermined target level, the upper sensor 544 provides a signal to stop operation of the pump 518 and / or close a valve to stop flow of water into the water level automation chamber 526 from the external source. For example, when the water level is below the target level, the valve 536 is in an open position and the water from the external water supply is allowed to flow into the water level automation chamber 526 until the water level reaches the target level, which is above the minimum operating water level. When the water level in the water level automation chamber 526 is above the minimum operating water level, the pump 518 is activated and able to cause water to flow through the outlet 538 and through the water line 106.

[0090] After being withdrawn from the water level automation chamber 526, the water flows from the pump 518 to the second fdter 548, the third filter 549, the fourth filter 550, and the UV sterilization system 551. The filtered water flows from the UV sterilization system 551 to the outlet 504 where the water may be discharged from the system 500.

[0091] FIG. 13 is a schematic diagram of the system 500, illustrating flow of rainwater into the system. A rainwater collection system may be coupled to the inlet 554 of the rainwater chamber 552 such that rainwater flows into the rainwater chamber through the inlet. The inlet 554 includes a filter (e.g., a leaf filter) 555 to remove debris from the water. When the rainwater chamber 552 is full, the water flows from the rainwater chamber 552 and into the water level automation chamber 526. Some water flows toward the water storage tank 524 to raise the level of the water storage tank equal to the level of water in the water level automation chamber 526. If enough rainwater is received, the rainwater flows into the water level automation chamber 526 to cause the water level to raise above the target level and to fill up the chambers. Flow of water from the external water source into the water level automation chamber 526 is stopped when the water level is above the target level.

[0092] When the water level is above the minimum operating level, the pump 518 is powered on and the water is withdrawn from the water level automation chamber 526 through the outlet 538. The water is filtered and may be discharged from the system.

[0093] In the example, the system 500 includes automation and regulation system 564. For example, the automation and regulation system 564 includes electronic automation valves, such as the valves 512, 514, 536, and 558, a control box or relay incorporated into the controller 520, and sensors, such as the sensors 544, 565. The electronic automation valves receive signals and open or close in response to the signals and, thereby, regulate operation of the system 500. For example, the electronic automation valves are connected to the water line 506. The closed or open position of the valves allows or inhibits flow through the water line 506. The information from the sensors is used to switch the valves between the open and closed positions. Also, the pump 518 and / or the water supply source are activated and deactivated based on signals from the sensors.

[0094] The automation and regulation system 564 operates at least in part without input from users. For example, the valves are opened and closed automatically based on water presence or water levels. Suitably, the components are directly operated by switches on the sensors. For example, the switches open or close circuits that directly provide power to the components and, thereby activate or deactivate the components. Accordingly, the system 500 is simple to operate in remote locations where there may not be technicians or personnel who are completely trained on all components of the system 500. Moreover, the automation and regulation system 564 does not require a network, internet, or mobile connection and can be operated in an isolated location.

[0095] FIG. 14 is a perspective view of a system 600 for filtering and storing water. The system 600 is similar to the system 500 shown in FIGs. 11-13, except as described. For example, the system 600 includes two of the rainwater chambers 552 instead of the single rainwater chamber 552 shown in FIG. 11.

[0096] The system 600 is mounted to a surface 602 and arranged along a wall 604 of a structure 606. For example, the system 600 is positioned on the surface 602 in a level manner to facilitate proper water flow. The system 600 is connected to a rainwater collection system 608 on the structure 606 and arranged to receive rainwater from the rainwater collection system. For example, the system 600 is positioned at a ground level of the structure 606 and the rainwater collection system 608 collects and delivers water from a roof of the structure positioned abovethe system. Suitably, gravity facilitates water flowing into and through the system 600 because of the location of the system.

[0097] The system 600 processes the water and provides usable water for users of the structure 606. For example, the structure 606 may be a school and the water may be provided for school attendees.

[0098] In the example illustrated in FIG. 14, the system 600 includes a frame 610 and a housing 612 supporting components of the system 600. For example, the frame 610 supports the rainwater chambers 552 and the water level automation chamber 526. The housing 612 encloses components of the system 600 such as the fdters 508 (shown in FIG. 11) and / or the pump 518 (shown in FIG. 11) that are mounted to a portion of the frame 610.

[0099] The housing 612 and the frame 610 may be separate or may be connected to each other. For example, components of the system are mounted to the frame 610 and the housing 612 encloses at least a portion of the components mounted to the frame 610. The frame 610 illustrated in FIG. 14 includes separate (e.g., not attached) portions and the housing 612 is connected to one of the portions. In other embodiments, the frame 610 includes a single, unitary structure.

[0100] The housing 612 and the frame 610 facilitate shipment and installation of the system 600 at remote locations. For example, the housing 612 and the frame 610 are modular. Moreover, the housing 612 and the frame 610 support and protect the system 600 from the environment and make the system more robust.

[0101] In one example, a water fdtration system includes a water chamber, an inlet arranged to receive water, an outlet arranged to dispense water, a water line fluidly connecting the water chamber to the inlet and to the outlet, and a filter arranged along the water line between the water chamber and the inlet or the outlet to filter water flowing through the water line. The water filtration system also includes a frame supporting the water chamber, the inlet, the outlet, the water line, and the filter.

[0102] In another example, a water filtration system includes an inlet arranged to receive water, an outlet arranged to dispense filtered water, a water line fluidly connecting the inlet and the outlet, and a filter arranged along the water line to filter water flowing through the water line. The water filtration system also includes a water level automation chamber arranged along the water line between the inlet and the outlet. The water level automation chamber defines a cavity that receives water. The water level automation chamber includes a valve that is configured to stop flow of water into the water level automation chamber when the water level within the water level automation chamber is at or above a target level.

[0103] In yet another example, a method of assembling a water filtration system includes connecting a water chamber to a water line. The water line fluidly connects the water chamber to an inlet arranged to receive water and an outlet arranged to dispense water. The method also includes connecting a filter along the water line to filter water flowing through the water line between the water chamber and the inlet or the outlet, and mounting the inlet, the water line, the outlet, the water level automation chamber, and the filter to a frame.

[0104] Examples of the systems and methods for storing and filtering water are described above and include modular water handling systems and tanks. In addition, the systems include simple and relatively cheap filtration components. Moreover, the systems are simple to install and implement at remote and rural locations. Accordingly, the systems and methods reduce the cost to provide access to clean water, and increase the availability of clean water at remote and rural locations.

[0105] When introducing elements of the present disclosure, the articles "a", "an", "the" and "the" are intended to mean that there are one or more of the elements. The terms "comprising", "including" and "having" are intended to be inclusive and mean that there may be additional elements other than the listed elements. Moreover, the use of “top”, “bottom”, “above”, “below” and variations of these terms is made for convenience, and does not require any particular orientation of the components.

[0106] As various changes could be made in the above without departing from the scope of the disclosure, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
