Can I generate hydroelectricity from running borewell water, if so how and the websites to refer to.?

I would like to generate hydroelectricity from running borewell water with continuous supply and in turn run the borewell itself so as to save electricity and dependence. If so, can I use autoswitch mode so that when the power generated is enough to run the borewell wherein it can switch itself from electricity supply (Govt.) to hydroelectricity. Pls let me know some of the simple experiments, the required gadgets, and the websites where to look for such things precisely.
