About Water Systems
A water system is needed to pump the water out of the well to the surface and deliver it under pressure to the place where you will be using it. A typical home water system, as indicated below, consists of a pump, a pitless adapter or unit and a pressure storage tank and control devices that allow the system to operate automatically.

Water Well Construction
A well is the most common way to obtain groundwater for household use. A well is basically a hole in the ground, held open by a pipe (or casing) that extends to an aquifer. A pump draws water from the aquifer for distribution through the plumbing system. The depth to which wells are constructed is determined by factors such as the depth of groundwater, groundwater quality and geological conditions at the well site.
Wells in Minnesota range in depth from 15 feet to over 1000 feet. The average household well is approximately 100-300 feet deep. Wells that are drilled very near each other often have similar depths. However, the depth of wells in glacial deposits can vary greatly - even if they are located next door to each other.
The State of Minnesota requires that wells be installed away from sources of contamination or interference; therefore, distance regulations have been imposed by the State for this purpose.

The average well requires one day to drill and one day to install the pump and run plumbing and electrical lines from the well to the house. Barott Drilling Services, Inc. offers installations with PVC or steel casing.

Sealing (Abandoning) unused wells
Unused or abandoned wells that have not been properly sealed can provide a direct pathway for contaminants to enter the groundwater. Contaminants from surface water, runoff, or sources, such as leaking sewers or septic system drain fields, can enter the well through casings that have deteriorated. An unused, unsealed well can potentially threaten water quality for new wells. Unused wells also pose a safety hazard, especially for children, pets, and livestock. It is illegal to dispose of wastes in an unused well, and it will result in additional costs to clean the well and possibly the groundwater before the well is sealed.
According to Minnesota law, a well must be sealed in any of the following situations:
1) The well is contaminated and cannot be corrected.
2) The well has been improperly sealed in the past.
3) The well poses a threat to the health or safety of the public or to groundwater quality.
4) The well is not in use and does not have a maintenance permit.
A water well is properly sealed when it is removed from service and is completely filled with an approved grouting material by a licensed contractor.
YOU MAY NOT SEAL YOUR OWN WELL! ONLY A LICENSED WATER WELL CONTRACTOR MAY SEAL A WELL IN ACCORDANCE WITH MINNESOTA LAW.
THERE ARE THREE MAIN STEPS THAT ARE FOLLOWED WHEN A WELL IS SEALED
1. Before a well can be sealed, all obstructions in the well (an old pump, drop pipe, and debris) - must be removed. In some situations, the well casing will have to be perforated - meaning that holes will have to be punched through the casing. This helps ensure that both the inside and the outside of the casing will be completely sealed when grout is pumped into the well.
2. The well is sealed by completely filling it with grout, which is a special type of cement, concrete, or a clay known as bentonite. Filling the well casing with grout seals the well and helps protect aquifers from contamination. To ensure a complete and effective seal, free of voids, Minnesota regulations require that the grout be pumped into the well from the bottom upward. The licensed well contractor inserts a grout pipe (or tremie pipe) all the way down to the bottom of the well, and then pumps in the grout until it comes out the top.
3. After the well has been sealed, the licensed well contractor will send a Well and Boring Sealing Record to the property owner and to the Minnesota Department of Health. The property owner should keep this document with other important papers relating to the property.
