Rain Water Harvesting Projects - Blind Home
Project Brief :
The Muncherjee Nowrojee Banajee Industrial Home for blind, started functioning from July 1956 as an industrial home for visually impared men in the bunglow situated at Jogeshwari, aptly named 'Chateau Dieu' of late Senrenebai M. Banajee, the well-known philanthropist.
Area of Implication :
Blind Home is located on in between S.V. Road & railway lines. Since there is no storm water drain system on this road, during rainy season, there was always a flooding situation due to the rain water coming from S.V. Road.
The entire plot area for Blind Home is 8000 sq.m. and 1,00,000 sq.m. catchment area from S.V. Road.
Pre Scenario:
Initially, when site was visited with the intention of Rain Water Harvesting System, it was observed lhat, the entire monsoon water from plot i.e. for terraces of three buildings and open spaces as well as water from S. V. Road was entering in the compound from West side & flowing towards Eastside compound wall and stagnating, creating flooding condition which were dangerous for Blind inmates. They had to travel through 4' to 5' deep water. Hence the rearside compound wall used to punctured to allow the water to flow to western railway line, which use to flood the entire area S stop main artery of Mumbai. However in March -April there use to be shortage of water for blind inmates
Work Implementation :
Rain water from all sides, as well as from the road was collected into the storm water drain which is all along the internal road and plot boundary. The storm water drain was connected to holding pit around the well with filtration media (i.e. sand, coal, pebbles ) and short bores of 20ft. Deep 8 in numbers around the well. This pit holds the entire day's monsoon water allows the water to percolate into the ground quickly. So there is not much water left on the surface.
Post Scenario :
At our site, blind home, Jogeshwari, we have collected the rain water falling on ground by providing storm water drain which was connected to filtration media (sand, coal and pebbles) and then to the well to charge the deep water cavems.
This resulted in stopping the flooding situation at our site and also at railway lines
Outputs & Outcomes :
This system increased Ground Water table and also the quality of water and thus the water yielding capacity of the well got increased till the beginning of the next monsoon. Due to increase in ground water table, the pumping cost reduced by Rs. 30,000/- per year which is also a tremendous saving for Blind Home.
