Third World & Rural Setup

Shown below is a typical bicycle-driven pump setup for pumping a small diameter water well using a 1/4 inch pumping tube. The gearing and tube diameter can be changed to optimize pumping effort for the desired flow rate. With a setup like this, clean water from the bottom of a surface sealed small diameter (2") well can be pumped from depths of 200 feet or more.
