There are cases where locally there will be a layer below the open 5 6 Bangalore is growing at an unprecedented rate, and its sprawling well in the sponge where water from the recharge well does not go expansion outpaces the public utility’s ability to accommodate into the sponge itself. Instead it builds an underground lake and that skyrocketing demand for water and sanitation services. It is becomes the shallow acquifer. The recharge well then starts yielding. increasingly common for new residential communities to assume total management for their own water and sanitation services through their Over a very long time, deep acquifers can get saturated too, and this resident welfare associations. Most of these depend on borewells and can build a shallow acquifer above. As more and more water is tankers, which they sooner or later realize is not a sustainable option. continually drawn from the acquifers, yields (for borewells or open Groundwater recharge, one of the forms of Rainwater harvesting, can wells) tends to fall off over time, unless recharging is being done. be instrumental in efforts to achieve long-term water security. By Place all the rings and center them Complete the well by packing Jelly taking water out of over-stressed storm drains and replenishing them Did you know? all around the RCC rings into shallow aquifers, groundwater recharge wells effectively raise Residents who have done continuous recharge for a water tables and reduce the intensity of flooding in a layout. period of 2-3 years have revived wells now that yield 7 8 water all through the year. These houses can do without corporation water supply. The making of a Recharge Well A Recharge Well can be easily constructed using concrete rings of diameter ranging from 2 feet to 6 feet and depth of 20 feet to 30 feet to store large volumes of rainwater and recharge the groundwater under Place a strong perforated RCC For large quantities of water good hydrostatic pressure. About 70% of the water will percolate cover or a grill for safety. The (industries, layouts...), a Percolation vertically, the other 30 % horizontally through the holes provided in the water should be filtered to remove test should be done with the first rings. The soil profile of the site helps to determine the depth of the well, the silt and leaves before it enters well, to see how fast the water its bottom should reach a critical level of the weathered zone, where the the well through an internal pipe. enters into the ground, and thus the water can easily percolate. number of wells necessary can be 1 2 known. The diagram above explains Bangalore’s geology- below the top soil is the weathered zone, which is made of rock and behaves like a How can I clean/ filter the water before sponge. This layer changes from area to area. Then comes the bed sending it to the Recharge Well? rock layer. The bed rock is not a monolithic layer; the rocks have cracks and fissures through which water passes and gets Identify the catchment area and ensure that it is clean and accumulated inside the rock. This is a deep acquifer. Borewells break unpolluted, make sure there is no sewage close by. Especially into the bed rock and taps into the water there. when water is picked up from lawns it should be free from fertilizer and pesticide. The golden rule for recharge is put in only What is recharging? Excavation: Dig a well having Lower the RCC rings one by one what you can take out and drink. Recharging is process of letting water back into the earth. A recharge dimension 2” more in diameter, into the well .

Recharge wells are dry wells, in the sense that they water runoff from the send water down in one direction, and do not yield water (initially at 3 4 storm drains is filtered by least) themselves. placing a slab and leading the water into a pipe Will I get this water back? which has been covered Imagine a dry sponge and you are pouring water through a hole into with mesh and jelly to the sponge. The water soaks up the sponge. Sooner or later, the purify the water. sponge will hit a saturation point. At that point water appears back in the recharge well and it starts yielding. When this happens (all recharge wells have this potential) a recharge well becomes an open Is it safe to dig a well in a Residential Area? well. The Jelly is then lowered into 40 mm Jelly the well and packed between the rings and the well to ensure the rings are in place
