Annual Open House   Click for More Detail

Each year, we sponsor an open house at our Wastewater Treatment Center. We host hundreds of guests, including scout troops, school groups, environmental advocates, local officials and any interested public. Guided tours of our facility are provided. We are proud to demonstrate how the treatment process works, and even include the chance to see the native fish that thrive in our treated effluent.

Our open house is held the first Saturday of October each year.
