Key Takeaways
- Innovative rainwater reuse model established by Coimbatore Corporation.
- Direct storage and reuse of rainwater for non-potable purposes.
- Tank capacity of 1.08 lakh litres, providing water for 10 weeks.
- System designed to capture rainwater from 25,000 square feet.
- Dual approach of rainwater reuse and groundwater recharge.
Chennai, Sep 23 (NationPress) The Coimbatore Corporation's groundbreaking rainwater reuse model is yielding remarkable outcomes, establishing the city as a leader in sustainable water management within Tamil Nadu.
In contrast to the majority of government structures across the state that primarily focus on rainwater harvesting (RWH) for groundwater recharge, the corporation has pioneered a system that directly collects and repurposes rainwater for non-potable applications at its Town Hall headquarters since July.
This specially constructed tank was nearly filled following the rainfall in September, showcasing the model's effectiveness.
Encouraged by this achievement, the corporation is gearing up to broaden the initiative across all five zonal offices, with the goal of decreasing reliance on borewell water and encouraging sustainable urban practices.
The system is engineered to capture rainwater from a built-up area of approximately 25,000 square feet through 40 collection points.
The tank boasts a capacity of 1.08 lakh litres, enhanced by a European filtration system, providing sufficient water for nearly 10 weeks.
Plans are also in motion for an additional ground-level tank with a capacity of one lakh litres to further bolster the system’s storage capabilities.
Incorporating a filtration mechanism with a removable dirt-collecting basket, the model ensures easy maintenance and sustained efficiency.
The collected rainwater serves daily non-potable requirements exceeding 8,000 litres. To maintain equilibrium, any surplus water from the tank is redirected into a groundwater recharge system adjacent to the borewell. This dual strategy of rainwater reuse and groundwater recharge optimizes the use of natural resources while minimizing waste.
The system effectively tackles issues commonly observed during the monsoon season, where excess water can lead to flooding or is diverted into stormwater channels.
By illustrating the viability of rainwater reuse alongside groundwater recharge, Coimbatore has established a benchmark in water management.
If adopted by other cities, this model could revolutionize how urban areas in Tamil Nadu conserve and manage rainwater, especially during the rainy seasons.
Point of View
Coimbatore's innovative rainwater reuse initiative highlights the importance of sustainable urban practices. As climate change intensifies, such models could serve as essential frameworks for cities across India, emphasizing the need for effective water management strategies. The success of this project not only addresses immediate water needs but also sets a precedent for collaboration between government bodies and communities in fostering sustainability.
