WATER SECURITY FOR VILLAGE GAVHALI THROUGH ROOF TOP RAIN WATER HARVESTING

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
