Rainwater Harvesting System in health care center
Need
Since 4 years low rainfall in our state results in lower ground water level that’s why we was faceing the water shortage in summer season in our health facility
Day by day patient load is increasing in our facility. And water consumption is also increasing.
Previously we have water consumption of 4000 ltr to 6000 ltr daily. Now we required around 6000 ltr to 8000 ltr water daily.
So, we decided to save water by rainwater harvesting system.
Rainwater Harvesting System
Description of the model





Capacity
Total roof area=12200 square feet/1133 square meter
Filtration tank capacity=60654 liter
Total rainfall (2019-2020) =54 inch/ 1371 mm
Roof catchment capacity=Annual rainfall(in mm) X Roof surface area (in square meter) 1371 mm X 1133 square meter = 1553343 Liters
Rain water for infiltration= 410432 gallons/1553343 liter approx
Evidence of Effectiveness
Previously in 2018-19 the ground water level in our tubewell was around 250-300 feet. And after implementing the rainwater harvesting system the ground water level decreases to 180 to 200 feet.
Now hospital’s water need for drinking water and other water requirement is satisfy even in summer season very smoothly.
