Pool Water Management System with Storage Tank
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water management systems in swimming pools are not optimal, leading to unnecessary water rejection during filter cleaning and inefficient use of recycled water, resulting in increased water consumption.
Innovation Solution
A water management system that includes a hydraulic set with a filtration system and a water storage tank, where the filtration system filters water from both the pool and the storage tank, allowing for closed-loop filtration and optimized water reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an overflow is implemented to evacuate excess water from the pool, then water level control is improved, but water is unnecessarily discharged due to water movements and bathers
Solution Approach 1:
A storage tank is introduced as an intermediary component between the pool overflow and the sewer system. Instead of directly discharging overflow water to the sewer, the system routes it through the storage tank where it can be temporarily held and later reused to refill the pool, thereby reducing unnecessary water loss while maintaining effective water level control
Solution Approach 2:
The system recovers water that would otherwise be discarded through the overflow. By capturing overflow water in the storage tank and recycling it back to the pool through the filtration system, the system transforms what was previously wasted water into a reusable resource, significantly reducing water consumption
2Ease of operation
If a sand filter with multi-function valve is used for pool filtration, then filtration simplicity is improved, but water consumption increases during backwashing operations
Solution Approach 1:
During backwashing operations, instead of discharging the dirty water directly to the sewer, the system redirects it to the storage tank. This recovered water, although containing some impurities, can be subsequently filtered through the pool's filtration system and reused, thereby reducing the overall water loss associated with backwashing while maintaining the simplicity of sand filter operation
3Ease of operation
If excess water from the pool is discharged to the sewer, then water level management is simplified, but water conservation is worsened
Solution Approach 1:
The storage tank serves as a mediator that intercepts overflow water before it reaches the sewer system. This intermediary component enables the system to maintain simple water level management through the overflow mechanism while simultaneously conserving water by storing and recycling the overflow through the filtration system back to the pool
Solution Approach 2:
The system establishes a feedback loop where overflow water is captured, stored, filtered, and returned to the pool. This closed-loop approach ensures that water is not lost but continuously circulated and reused, reducing overall water consumption while maintaining effective water level management

AI summary
The invention relates to a pond water management system, the system comprising a hydraulic assembly and a storage tank (520). The hydraulic assembly comprises a pond (500) provided with a water outlet (510) to be filtered and a filtered water inlet (514), a filtration assembly (502) configured to filter water received directly or indirectly from the water outlet (510) and supply the filtered water to the water inlet (514) of the pond (500), and an overflow (518) for discharging excess water from the hydraulic assembly. The water storage tank (520) comprises a water inlet (522) and a water outlet (524). The filtration assembly (502) is further configured to filter water received directly or indirectly from the water outlet (524) of the storage tank (520) and to supply the filtered water to the water inlet (514) of the basin (500) and/or to the water inlet (522) of the storage tank (520).
