Wellhead Protection

Where does my drinking water come from?Legacy logo for Wellhead Protection.jpg

The City of Minnetrista water system provides safe, clean drinking water to approximately 4,000 residents and businesses in Minnetrista. The City's source of drinking water comes from groundwater. Groundwater is the water that soaks into the soil from rain or snow and moves downward to fill cracks and other openings in beds of rock and sand, also known as aquifers.

How is water pumped into households?

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 (casing) that extends to an aquifer. A pump draws untreated water from the aquifer for distribution through the plumbing system.

What s a wellhead protection?

Wellhead protection is a means of protecting the area surrounding public drinking water supply wells, and in turn, protecting drinking water supplies.

As a part of the City's commitment to protect local groundwater and drinking water supplies, we have implemented a Wellhead Protection Plan (WHPP). The goal of the WHPP is to identify and manage potential sources of contamination in areas that supply water to the City's wells. Implementation of the plan includes taking actions to prevent contamination throughout the Wellhead Protection Area (WHPA).

The Wellhead Protection Area is the surface an subsurface surrounding a well that supplies the City's water system, through which contaminants are most likely to move toward and reach the well.
