Need of Rain water harvesting
Ground water resources will not get recharged because of the density of the houses in the city’s. there will not be any empty space for water to go into the ground. Because of changing weather conditions, rain percentage is decreasing year by year. It is everybody’s responsibility to save water. Rain water harvesting is the only option to increase ground water levels.
What is Rain water harvesting:
Rain water harvesting is a process of collecting rain water and reusing this water for daily needs and instead of sending this water in drains
Reusing rain water can be done in many ways
- Connecting the water to sump after purifying
- Send excess water into soil by rain water harvesting recharge pit
Rain water harvesting recharge pit:
You need to dig the soil 5 t0 6 feet depth
Arrange cement rings in pit
Fill recharge pit with Sand, and Jelly:
Fill recharge pit with 40 mm jelly, 20 mm jelly, river sand. Each layer for ~ 8 inch depth. Repeat the layers until you get till the top.At the bottom of the Pit fill 40 mm jelly. On top of 40 MM fill 20 mm jelly. on top of the 40 mm you can fill gravel which came from sand filtration process. as a final top layer fill the sand. Give 1 – 1.5 inch gap between sand and inflow pipe so that excess water will have a room to go inside
Connect out flow pipe from recharge pit to drain :
Keep a out flow pipe to the drain. In case of heavy rain water will not seep fast into soil. In this scenario water will overflow from recharge pit. Through this out flow pipe excess water will be sent out instead of overflow
You can observe outflow pipe in bottom right corner of the photo
Collect rain water from top :
Collect all the rain water from top floor through PVC pipes and connect inflow pipe to rain water harvesting recharge pit
Inflow pipe in recharge pit :
