Information
& Education

There are two phases in the water well/water system installation process. The first step is to decide on a location and then drill the hole, install and grout the surface casing, and finally, install the liner. This process allows access to the water supply available to us from the ground.

The next step is to install the necessary machinery, equipment, plumbing, and wiring to bring the water from far down in the ground up to the surface. These parts include the pump, pressure tank, water line, electrical wire/conduit, pitless adapter, check valve, pressure switches, etc. Once these components are installed and power is supplied, you are tapped into the most economical source of water available today.

The Missouri Department of Natural Resources (MO-DNR) Web site has hyperlinks to several Adobe Acrobat .PDF files containing further information regarding rules, standards, and guidelines for wells and water systems that are specific to the state of Missouri.

Some of these MO-DNR rules, particularly those which may be of the most interest to current and future Missouri well owners, have been extracted, converted to HTML format, and listed below in order to provide you with convenient access to this important educational information.
