Roof top rainwater harvesting ppt. Removes rooftop debris protects tank water quality install above or below ground filter capacity up to 33 000 ft2 1. Well recharging method 2. 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. It can eitherbe stored in a tank or diverted to artificial recharge system this method is less expensive and very effective and ifimplemented properly helps in augmenting the groundwater level of the area 9.

Components of the roof top rainwater harvesting system. Total roof top surface area 13910 sq. 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. Borewell recharging method other minor methods are y farm pit method y farm trench method costs and economic viability of roof water harvesting system y two types of systems.

It consists of conservation of roof top rain water in urban areas and utilizing it to augment ground water storage by artificial recharge. Roof top rain water harvesting system. Average annual rainfall in mm 792 4. Roof top rain water is collected in collection chambers and diverted to recharge wells through interconnecting pipe lines.

Total volume of rainwater harvested 4446 metre cubic. Water requirement is met by one bore well and is supplemented by municipal supply. The main objective of rooftop rain water harvesting is to make water available for future use. Rainwater harvesting systems installed in multistoried buildings can suffice for daily water usage by the building residents.

Rainwater harvesting seminar and ppt with pdf report. Roof top rain water harvesting system rooftop rainwater recharging y following are the methods of recharging ground. Pre tank filtration after m ore than 20 years in the rainwater industry rainwater managem ent solutions has identified the w isy 4 step system as the ideal m ethod for 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.

In the areas of regular rainfall the perfect alternative to overcome the water. Rooftop rain water harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs. In rooftop harvesting the roof becomes the catchments and the rainwater is collected from the roof of the house building. 1 catchment area 2 transportation 3 first flush 4 storage system 5 delivery system 6 filtration system 8.

This technique is particularly useful in dryland hilly urban and coastal areas.
