At present approximately 783 million people in the world lack access to safe potable drinking water. The solar energy based submersible- dual pump has been seen to be a viable option for supply of drinking water throughout the year. In this scheme a solar energy based submersible as well as hand pump is fitted in the same bore well. This drinking water supply scheme gives continuous water supply throughout the year as people can extract water by hand pump when there is no solar power available particularly in rainy season. When the water level goes down i.e. below 36m particularly in summer season below the lifting capacity of Mark-II hand pump people face lot of problem in collecting potable drinking water. During summer season when there is frequent power shortage and failure this scheme can give uninterrupted drinking water supply and drinking water security. Once this project is implemented (approximate cost in India is Rs 6 lakhs , $10,000) by the government the operation and maintenance cost is around Rs 30.00 ($ 0.5) per family per month. With the present socio-economic condition, rural people can afford for the monthly maintenance which is important for the sustainability of the project.
