Water plays a major role in any agricultural or farming based activity. In India, groundwater levels have fallen as much as 70 meters or more over the past 30 years. Assessments by the Central Groundwater Board, Government of India, show a dramatic change in share of tube wells in irrigated areas – from a mere 1% in 1960-61 to 40% in 2006-07. Efficient water conservation is therefore a natural step towards sustainability with respect to water resources. The goal at GEV was to create a system which could help us attain our goal without disturbing the existing ecology while keeping cost feasibility in mind. Therefore we undertook a hydro-geological survey of the entire ecovillage to identify suitable recharge and discharge points. A recharge point is the ideal location to build rain water harvesting units to recharge the underground aquifers. A discharge point is the ideal location to draw underground water through open wells and bore-wells. The entire process involved the following steps:
