Project Clean Lake is a 25-year control program to reduce combined sewer overflows in our service area.


Below is a chart of current Project Clean Lake projects.

Pollution Reduction

This chart shows how pollution from combined sewer overflows (CSO) will be reduced annually as a result of Project Clean Lake programs through the year 2035.
Pollution Reduction Graph
Project Clean Lake initiatives increase the amount of flow being captured for treatment, thereby reducing the volume of overflow discharging to the environment. Green infrastructure projects also reduce the amount of stormwater flow entering the combined sewer system.
