Drilling companies charge thousands of dollars to tap ground water sources that you can often reach yourself with a few common tools and about two weekends of work.Methods ranging from digging to blasting are used to reach the underground layer of fresh water that lies beneath dry land. Most of these are too technical, expensive, or dangerous for the average person. However, at the turn of the century the U.S. Army developed a fast, effective method to provide bivouacking troops with water that did not involve a lot of expensive, cumbersome equipment. Soldiers simply drove a pipe into the ground with a sledgehammer until they reached the aquifer. Popular Mechanics.

A low cost alternative to using traditional water Micro Hydro turbines is to use a water pump as a hydro electricity generating turbine.
Single phase and three phase induction / synchronous motors can be used to generate single and three phase electricity to provide low cost power generation in remote locations of the world. Micro-Hydro is a valuable source of power generation in rural industries and remote village electrification schemes. What typical applications can Micro-Hydro be utilized for? Typically Micro-Hydro power can be used for projects demanding power in the range of 200W up to 30KW when using a water pump as a generator. A Typical C2C Capacitor Arrangement For A Pump As A Generator Below Pump as Turbine At the outlet from the PAT, it is advisable to use an expanding pipe, known as a draft tube, or a reducer in reverse to increase the diameter of the pipe where it discharges into the outlet channel. Micro Hydro. A small micro-hydro generator that receives flowing water under pressure (from an elevated dam or stream), uses the power of the water to turn an impeller, and the impeller's shaft turns the electric generator to make electricity.
To better understand how a micro turbine works, a water pump works in reverse of a hydro generator. For a pump, electricity is used to turn a motor at high speed (eg. 1720 rpm). The motor shaft turns an impeller. The impeller is in an enclosed case flooded with water. When the impeller turns, it sucks water in from the pump's suction inlet pipe, and forces the water out of the pump at significant pressure and flow through the pump's discharge pipe.
Hydro Electric Experiment. Pictured above is our neighbor Scott's Dam.
He's got a 4" diameter PVC pipe out of it, running down the creek about 15'. The total head here is about 3'. Our goal is to build a small hydro electric plant. In the past he had a machine he'd built from a squirrel cage blower, with a belt, to a PM DC motor. It produced about 1 amp, give or take a bit and he ran it year round for 2 years. We started with scraps of sheet metal and angle iron. The Vanes in the runner are made from quartered 4" diameter steel conduit. The sides of the runner are 12" diameter. The template is glued to one of the disks which make up the sides of the runner, and we have both disks clamped together. We put 10" between the two sides of the runner using allthread, and squared it up as best we could before installing the vanes. Here the runner is getting welded up. Pictured above the runner is pretty well tacked together. HEB Home. Blog - Sam Redfield on Pico-hydro at La Florida.
