Roof top rainwater harvesting ppt.

Harvested rain water can be stored in subsurface ground water reservoir by adopting artificial recharge techniques to meet the household needs through storage in tanks. In rooftop harvesting the roof becomes the catchments and the rainwater is collected from the roof of the house building. Rainwater harvesting systems installed in multistoried buildings can suffice for daily water usage by the building residents. Roof top rain water harvesting system.

Rooftop rain water harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs. Total roof top surface area 13910 sq. Rainwater harvesting seminar and ppt with pdf report. Roof top rain water is collected in collection chambers and diverted to recharge wells through interconnecting pipe lines.

1 catchment area 2 transportation 3 first flush 4 storage system 5 delivery system 6 filtration system 8. The main objective of rooftop rain water harvesting is to make water available for future use. Rainwater collected in the roof flows down the pipes running down the length of building into service wells or percolation pits water trickles down the layer of pebbles and boulders designed for underground filtration filtered water flows into either recharge well or the collection chambers with this setup the building can draw water readily from its water table in. Our earth is covered with 75 of water and 25 of land but water scarcity is a global issue because the large extent of water is not used for the domestic purpose irrigation purpose and one of the solutions for such problem is the rainwater harvesting.

Roof top rain water harvesting or domestic rainwater harvesting is the technique through which rain water is captured from roof components and stored in tanks reservoirs ground water aquifers.
