Building a rainwater harvesting system in a houseOctober 11, 2006
Last week, the NGO Samvada in Yelahanka (Bangalore) put its house in the hands of 16 young people from rural areas of all Karnataka. Looking for job opportunities, they want to work on water issues. Thus Samvada, with the help of the Rainwater Club, suggested them to learn how to built a rainwater harvesting system. After mesuring the roof area (127 m²) and the size of the existing tank (8000 liters), they have implemented in the house a new PVC pipes system from the roof to the sump tank, passing through a drum sand-filter. One day work and Rs 3000 have been necessary for them to learn how building such a system for an existing house, and allow Samvada to store 90 000 liters of rainwater every year ! So when will you be ready to put such a simple but effective system in your own house ?
