Project location: Suzuki Motor Gujarat Pvt. Ltd., Becharaji, Gujarat

Need: A natural drain used to pass through the plot of the Maruti Suzuki plant, but as the plant was being constructed the natural water flow was being hindered. So, a long reservoir was constructed on the edge of the plant connecting the drain. Yet, water logging was a persistent issue with the premises of the plant. To address this issue and to comply with statutory guidelines, a series of recharge structures were constructed.

Work done:

• Sujalaam has helped in technical analysis to do the groundwater recharge for such a large site and shared the design brief report to make the recharge structures across the site.

• There were 26 locations identified and a man made reservoir along one entire edge of the site was created to solve the need.

• The Class - V Infusion well system has been built to recharge the water at shallow sub surfaces of the strata. A stainless steel V wire screen has been installed for the initial filtration to happen at entry level of the pipe from the reservoir to recharge well.

• There are two structures - one is a desilting pit and the second one is a recharge borewell with a filter mechanism.

• After the initial filtration the water enters into the desilting pit in which soil and sediments in the water get settled here and water runs into the second well.

• In the second pit, a filter is fit above the borewell. This filter is made of two concentric SS V wire screens of different diameter holes (Inner screen in cylindrical shape with 6” dia. and out screen in 12” dia with 2m of total depth). A packing of filter media is done in between these two concentric screens. The water’s secondary filtration happens here before recharging at about 150 feet depth in the aquifer.

• About 28,500 cubic meter of Rainwater is recharged through 26 recharge structures.

• The man-made reservoir is built of the capacity of 43000 cubic meter.

Benefits:

• Water quality has improved over 3 years.

• Water logging problem on site has been taken care of and also retained the existing connection between two reservoirs through a channel.
