A Drinking Water Project in Sambhar Lake, Rajasthan

Located South West of Jaipur, the Sambhar salt lake has a catchment area of 5700 sq km spread across the districts of Nagaur, Jaipur and Ajmer in Rajasthan. It is said to be India's largest saltwater lake. As is only natural, the ground water for miles around is saline and unfit for drinking.

The lake has a history of salt production that goes back 1500 years. There are 100 villages bordering the Sambhar Lake. Salt is the source of livelihood for all these people and several thousand others in the area. It is also one of the main causes of ill-health. There is an urgent need for the ground water to be treated prior to human consumption.

The goal of the project is to provide the 5500 strong population of five villages with a localized supply of clean, safe and healthy drinking water. The Foundation for Rural Recovery & Development, (FORRAD) in collaboration with MANTHAN, has undertaken a 'Drinking Water Project through Solar Powered Reverse Osmosis Technology' in the villages of Sinodiya, Jhag, and Der ki Dani in District Ajmer and Mordikala and Solawata in District Jaipur, Rajasthan. The fabrication of the RO units has been undertaken by the Central Salt & Marine Chemicals Research Institute.

Each RO Unit is driven by 6 KW of solar power generated through 72 panels and a system comprising of batteries, panels and an inverter. Each unit has an average production capacity of 700 litres of water per hour and is run for ten hours a day. This yields a daily output of 7000 litres of drinking water.
