Kerala is one of the few water-rich States in India, receiving an average annual rainfall of 3000 mm. However, the State is yet to scientifically explore the full potential of the key natural resource for human, and agricultural and industrial purposes. As a result, despite its water richness, several parts of the State face acute shortage of water during the summer, the coastal areas of the State are the worst affected.
The fears of climate change, is set to worsen the unpredictability of water supply in coming years forcing the government to think of better management of water resources.
The State Government is planning to set up demand-driven participatory water supply projects which together entails an investment of Rs. 1000 crore. They include desalination plants, automation of water pipelines and canals, conservation and recharging of rain water, rainwater harvesting, waste water recycling and water purification.
