The Linn Sanitary District is happy to welcome you to our web-page. As we move into the next phase of the District’s sanitary wastewater management efforts we look forward to keeping you and all the District’s residents up-to-date and informed on what is going on through the use of this web-page.

The Linn Sanitary District meets the second Wednesday of the month at 7:00pm in the Town Hall meeting room. It is an open meeting and we encourage all who care to attend to do so.

Most residence in the Linn Sanitary District are served by private wells.  To assure that their drinking water is safe and that the groundwater that supplies water to Geneva Lake is of good quality, a comprehensive well testing program was conducted.  Working together the Linn Sanitary District, the Geneva Lake Environmental Agency, Walworth County Public Health and George Williams College identified, sampled and assessed over 400 private wells.

This program found that the ground water quality is good from a bacterial and nitrate perspective.
