WATER SECURITY FOR VILLAGE GAVHALI THROUGH ROOF TOP RAIN WATER HARVESTING

Abstract

The objective of this work is to compile and review the literature on Rain water harvesting, estimate the consumption of liter per capita per demand ( LPCD ) for domestic and potable consumption and establish that rain water harvesting is a practical, economical and sustainable system with ecosystem specially for rural areas Fresh water is a precious and limited resource that nourishes innumerable life forms. As population pressures increase, the majority of communities around the world face the prospect decreasing supplies of fresh water in general and many would have no access to potable water at all. This lack of access impacts human health around the globe as many dies from water borne diseases and related illnesses every year. In those communities where access to fresh water is limited and watershed health is of concern, one viable “lowtech” solution is to build a roof water harvesting system. By creating the means to store water on site, using the existing rainfall as the source and infiltrate on of the grey water and remaining run-off, one can eliminate the need to draw from precious ground water supplies and avoid the high costs (economic and environmental) of dependence on centralized conveyance and treatment systems. Humans benefit from having a self sufficient ecosystem. The ecosystem receives benefits from the reduced erosion, flooding and pollution caused by run-off and the reduction of demand on groundwater supplies. More than 60 % of Indian population lives the rural area, deforestation is the main reasons of imbalance in rainfall in every reasionof India; Satpuda is the top most range of mountain in Maharashtra which is situated on boundaries of Maharashtra – Gujarat, and Maharashtra- Madhyapradesh. This part of boundary area had a thick forest cover but now-a-days the percentage of forest area has depleted. Day by day it is going on decreasing ,Adiwasi people situated along the mountain regions face the water scarcity problem ,due to inadequate rainfall and ground water depletion, Gavhali villagers are face water scarcity in the month of April, May and June. A brief methodology of the work is put forth herein; Villagers of Gavhali face water shortage during the months from April to June. The aim of this project work is to ascertain the potential of roof - top rain water harvesting for three water scarce months. Case one is to estimate per capita daily demand of water which works out to 40lpcd for three months and cost of the system. Case two is to work out the per capita daily demand of only potable water which is calculated at the 10lpcd for three months and cost of the system.
