Rain Water Harvesting

Подпись: Rain harvesting in a residential building, is used for power generation as well as for floor cleaning, watering trees and car washing. One inch of rain is equivalent to 3,265 liters. (i.e. 1 cubic foot is about 28 liters) STETOLIZER Recycling of 100 %, grey water aimed. R&D projects will be undertaken soon at our institute to save, store and utilize the rainwater to a maximum extent, supplying the drinking water and the rest for power generation Rainwater collection sites / areas within or outside the building should ensure zero discharge to municipal / corporation channels.

6.1 Gutter details and collection of rain water

This plan is showing the details of rain water collection. Gutter details and rain rater collection method is also shown. Two particular filters and a ultra-violet light are used to sterilize water estimating 10 gallons of water per minute.

Rain water harvesting is broadly classified into two categories. They are surface runoff and roof-top harvesting. In both the cases, it is mandatory, prior to rainy season, to clean and maintain the segments free from all other contaminations that are added earlier. This harvesting is very much essential to cater the demands of water for drinking, domestic purposes and aimed to generate power and gas. In turn over a long range helps as follows:

• Conservation of water

• Reduction of soil erosion

• Arresting of ground water decline

• Beneficiates quality of water
