Wastewater Treatmentplant Tours

Whether you are taking a shower, washing your clothes or flushing your toilet, you are using water. We all know where water comes from, but where does our wastewater go? You can learn more with a tour of one of our Wastewater Treatment Plants at Lake Wildwood or Lake of the Pines. 

Nevada County Sanitation District handles nearly 1 million gallons of water every day through more than 110 miles of pipe and treats it all at 10 treatment plants in Western Nevada County. This free tour will give a behind-the-scenes look at the processes that make the system so reliable and that keep the environment and Nevada County residents’ safe. From the point that wastewater leaves a home or business and enters the treatment process, follow the water through the treatment process to where it’s released to local creeks and rivers.
