Estimation and Design of Rainwater Harvesting Structures to Siddharth Group of Institutions, Puttur

The present scenarios of groundwater tables are falling at a rapid rate. This is because withdrawn of groundwater is much more than the recharge of rain water. Artificial recharge of rainwater during rainy season will help the prevention of groundwater tables. An attempt is made to harvest the roof top rain water at Siddharth group of institutions. There were eleven blocks in the campus covering roof area of 1.11995279 hectors. The harvest water from roof tops by PVC Pipes are emptied into open channels and finally connected to existing bore wells (4. no) prior to letting into the bore wells, the roof top waters are treated by sand filtration to remove suspended solids being present in the roof top water. The total estimation of water harvesting from roof tops is RS 2.51 lakhs. The system will recharge around 23.627219x103 cubic meters per year.
