STI PITHAMPUR has recently developed unique water harvesting and recharging system called ‘aquifer recharging’ with the help of NGO ‘Samadhan Seva Samiti’ to provide clean and potable water to its employees and industry.

The NGO developed this method under the guidance of soil scientist Dr G S Kaushal, Dr Sadhuram Sharma and Dr D K Yadav. Samadhan Seva Samiti undertook the survey and prepared a project for STI. The NGO constructed contour trenches in 2755 m, 105 bore holes, earthen bunds, bolder checks, solid weirs, deep ploughing of 55 acres, dug out ponds, water harvesting tanks and four tube wells. The funding was provided by STI.

After completion of construction work a joint team from the NGO and STI surveyed the outcome of the project. STI chairman Ramesh Baheti informed that the results were obvious after a few rains.

The level of wells increased by 1.5-2.0 m and tube wells’ yield increased by almost 15 per cent. Insufficient rains did not affect the utility of the system. Water in dug out ponds and solid weir is also 2-3 feet deep.

Baheti said that the company could save up to Rs 10 lakh every year after the system works fully and water problem is solved. The system works on the principle that water follows contour and can be retained at one level.

Taking into consideration this principle, dead contour trenches of proper dimension could capture rainwater and be allowed to percolate. Bore wells and ponds further facilitate the percolation. Different structures can be built to provide stability to the landscape. The deep ploughing helps in saving every drop of water. The calculation of rainfall pattern in a particular area is also done to build the system.
