Water is the most basic resource that aids in village development. Sevabharathi Tamilnadu recognises this and takes various steps towards conservation of water in the rural areas. In villages, people are taught to clean and maintain ponds and tanks, construct small check-dams and apply rain-water harvesting techniques at the house and village levels. They are also educated about growing crops that suit the water availability in their locality. They are made aware of harmful plants that suck ground-water resource and are given tips about destroying them. Other useful ideas like drip-water irrigation and minimising water usage are also popularised.
