Standards and Details

The Lake County Public Works Department (LCPW) maintains 390 miles of sanitary sewer main, 250 miles of water main, three wastewater treatment plants, 12 water systems, and other associated infrastructure.  We all work together to ensure that system is well-maintained and operating costs are as low as possible. It is important we all meet consistent standards of material quality and construction procedures. 

The standards below apply to all public and private infrastructure:
