More specifically, the present invention relatesto the field of machines and systems for drainage water removal, cleaning andtransport to a safer side. Even more specifically, the present invention relates to anautomated and mobile machine for dewatering sewage deposits that separatesdeposits from unfiltered drainage water in a user-friendly and environment-friendlymanner, maintains the smooth flow of drains during the dewatering process, andenables easy and timely disposal of filtered deposits.BACKGROUND OF THE INVENTION

[001] Background description includes information that may be useful inunderstanding the present invention. It is not an admission that any of theinformation provided herein is prior art or relevant to the presently claimedinvention, or that any publication specifically or implicitly referenced is prior art.

[002] In urban as well as rural areas worldwide, the efficient functioning ofopen / closed drainage water systems is vital for maintaining public health andenvironmental hygiene. However, these systems often face significant challengesdue to the accumulation of deposits such as silt and sludge. These deposits,commonly found in open / closed drains and sewage systems, pose multifacetedproblems that demand attention for the prevention from hazardeous atmosphere,where wind is a strong carrier.

[003] Open drain sewage systems are designed to carry wastewater away fromhomes, businesses, and industrial sites to treatment facilities like landfill sites.Along the way, various types of debris, including silt and sludge, can accumulatewithin the open drains. This accumulation can impede the flow of wastewater,leading to blockages and backups that create significant sanitation andenvironmental challenges. Unlike enclosed sewers, open drains are more exposedto additional debris and contaminants from their surroundings, exacerbating theproblem and necessitating regular maintenance to ensure their proper functioning.

[004] Silt is primarily composed of fine particles of soil and sediment that arecarried by runoff from streets, sidewalks, and other impermeable surfaces. Duringrain events, these particles travel into storm drains through water flush, which areoften connected to the drain / sewage systems. Over time, silt settles and accumulatesat the bottom of the open drains, reducing their capacity and hindering the flow ofwastewater.

[005] Sludge, on the other hand, is a mixture of organic and inorganic materialsthat settle out of the wastewater itself. This can include organic matter such as foodwaste, fecal matter, and grease, as well as inorganic solids like sand, grit, and debris.As wastewater travels through the sewage system, the velocity decreases, allowingheavier particles to settle and form a layer of sludge along the bottom of the pipes.

[006] The presence of silt and sludge in drainage water systems impedes the flowof water, leading to blockages and backups. As a result, sewage water may overflowonto roads and public spaces, causing sanitation concerns and potential healthhazards. Moreover, the accumulation of sludge on road surfaces exacerbates theseissues, as it not only emits foul odors but also serves as a breeding ground forbacteria and other pathogens, polluting the surrounding environment.

[007] Manually separating sludge from water is a time-consuming process thatcan take days to complete. During this period, the cleanliness issues persist, withsludge remaining on roads for extended durations, further compromising hygienestandards and public well-being. Additionally, the manual extraction of water fromsewage systems / open drains for sludge filtering disrupts the smooth flow of sewage,exacerbating the efficiency of the drainage system.

[008] Furthermore, the lack of proper mechanisms for the accumulation anddisposal of sludge exacerbates the problem. Inadequate infrastructure often leads tothe haphazard dumping of sludge onto roads, where some of it may find its wayback into drains, perpetuating the cycle of contamination. The resultant pollutionnot only affects the immediate surroundings but also poses long-term health risksto residents.

[009] US9199861B2 discloses methods, systems, and / or apparatus for treatingwastewater produced at thermoelectric power plants, other industrial facilities,and / or similar industrial sources. The wastewater is directed through a wastewaterconcentrator that includes a direct contact adiabatic concentration system. A streamof hot feed gases is directed through the wastewater concentrator, where it mixesdirectly with the wastewater and evaporates water vapor from it. The wastewaterconcentrator then separates the water vapor from the remaining concentratedwastewater. Additionally, a contained air-water interface liquid evaporator may bearranged to pre-process the wastewater before treatment by the wastewaterconcentrator.

[010] Previously, efforts have been made to address the issue of sludgeaccumulation in open drains and sewage systems through stationary equipmentdesigned for sludge removal. While these systems are effective in extracting sludgefrom sewage, they are limited by their lack of mobility and integrated machinery,making disposal a logistical challenge. Without the capability for easytransportation to landfills or designated disposal sites, the accumulated sludge oftenends up exacerbating cleanliness issues by contributing to roadside accumulationand environmental pollution. Thus, while these stationary solutions may alleviatesome aspects of the problem, they fall short of providing a comprehensive andsustainable solution to the challenges posed by silt and sludge in drainage watersystems.

[011] In light of these challenges, there is an urgent need to envision innovativesolutions that address the root causes of drainage system inefficiencies. A mobileand automated machine capable of efficiently removing silt and sludge from opendrains and sewage systems could revolutionize urban sanitation practices. Bystreamlining the sludge separation process and facilitating proper disposal, suchtechnology could significantly mitigate cleanliness issues, minimize environmentalpollution, and safeguard public health. Moreover, by ensuring the smooth flow ofsewage and preventing blockages, it would contribute to the overall efficiency andsustainability of drainage water systems, paving the way for healthier and moreliveable environments.OBJECTIVES OF THE INVENTION

[043] The present invention relates to an automated and mobile machine fordewatering sewage deposits that separates deposits from unfiltered drainage waterin a user-friendly and environment-friendly manner, enables easy and timelydisposal of filtered deposits, and maintains the smooth flow of drains during thedewatering process.

[044] Referring to FIG. 1, an isometric view of a mobile machine (100) forcleaning drainage deposits is illustrated, according to an embodiment of the presentinvention. According to an embodiment of the present invention, the machine (100)is mobile in nature such that the smart machine is either mounted / assembeled on avehicle or is by itself a vehicle. The vehicle is atleast two-wheeler, wherein fewexamples of such vehicles could be a truck, tractor, excavator, auto, e rickshaw,Bulldozer, Backhoe Loader, Dump Truck, Front end loader, skid steer loader,grader, trencher, forklift, a concrete mixture truck, industrial transporter, sidemaintenance vehicle, trike or a mini dumper.

[045] In an instance, the source of unfiltered / dirty drainage water that is meant tobe cleaned / dewatered using the smart mobile machine may include but not limitedto a drain, canal, sewer, sewage, culvert, or river.

[046] In an instance, the deposits within the different types of sources ofunfiltered / dirty drainage water that need to be separated / dewatered using the smartmobile machine may include but not limited to sludge, stones, silt, lumps andsediments. Sediment is a broad category that includes all others like silt, sludge,lumps, stones and lumps. The primary deposits that negatively impact the drainagewater are silt and sludge.

[047] Silt is primarily composed of fine particles of soil and sediment that arecarried by runoff from streets, sidewalks, and other impermeable surfaces. Duringrain events, water washes these particles into storm drains, which are oftenconnected to the open drain sewage system. Over time, silt settles and accumulatesat the bottom of the open drain sewage system or within the sewage system pipes,thus reducing their capacity and hindering the flow of wastewater.

[048] Sludge, on the other hand, is a mixture of organic and inorganic materialsthat settle out of the wastewater itself. This can include organic matter such as foodwaste, fecal matter, and grease, as well as inorganic solids like sand, grit, and debris.As wastewater travels through the open / closed drain sewage system, the velocitydecreases, allowing heavier particles to settle and form a layer of sludge along thebottom of the pipes.
