11.7.1.6. Percolation tanks

Percolation tanks are artificially created surface water bodies, submerging a land area with adequate permeability to facilitate sufficient percolation to recharge the ground water. These can be built in big campuses where land is available and topography is suitable. Surface run-off and roof top water can be diverted to this tank. Water accumulating in the tank percolates in the solid to augment the ground water. The stored water can be used directly for gardening and raw use. Percolation tanks should be built in gardens, open spaces and roadside green belts of urban areas.

Percolation tanks are man-made bodies of water that help recharge groundwater. They are designed to be placed in areas that have enough land space and where the land allows water to seep into it easily. When it rains, water that runs off rooftops or surfaces can be directed into these tanks. The water collects there and gradually seeps into the ground, helping to replenish underground water sources. Additionally, the water stored in these tanks can be used for gardening or other direct purposes. Such tanks are typically set up in urban areas, like parks or along roadsides, where there is space for them.

Imagine a sponge soaking up water. When you pour water on a sponge, it absorbs the liquid until it's full. Similarly, percolation tanks act like sponges for the ground, helping to capture rainwater and letting it seep into the earth to refresh the groundwater supply.

Percolation tanks should be built in gardens, open spaces and roadside green belts of urban areas.

The ideal locations for constructing percolation tanks are areas that have ample open space, such as gardens, parks, or the edges of roads in cities. These locations not only have enough room for water to accumulate but also are often in need of better drainage and water management solutions. Constructing the tanks in these areas helps in maximizing water infiltration into the ground while also providing a natural approach to managing excess rainwater.

Think of a garden that collects rainwater in a small pond. This pond not only provides water for the plants but also allows excess water to percolate into the soil, preventing flooding and keeping the garden healthy. Just as a well-placed pond benefits a garden, strategically built percolation tanks serve urban areas by capturing and using rainwater effectively.

The stored water can be used directly for gardening and raw use.

One of the primary advantages of percolation tanks is that they provide a resource for irrigation and other direct water needs. Once rainwater accumulates in the tank and is filtered naturally through the soil, it can be drawn upon for watering plants in gardens or for other uses that do not require potable water. This is especially beneficial in urban areas where access to fresh water may be limited, and it promotes the careful use of available resources by recycling rainwater.

Imagine having a water bottle that you fill every time it rains. You can use that water to keep your garden healthy and vibrant. Similarly, percolation tanks collect and store rainwater, acting like that water bottle, helping you sustain your green spaces even during dry spells.
