Sanitary Sewage Treatment Services
The Lake County Public Works Department owns and operates three sewage treatment plants, also known as water reclamation facilities. We process the wastewater of approximately 25,000 direct customers and over 100,000 contractual customers by agreement with fourteen Lake County municipalities.

Our treatment plants are operated in strict compliance with federal, state and local regulations to protect our waterways from hazardous discharge.
