2022 Sewer Cleaning and Televising Program

Contractor: American Underground, Inc.

Project Contact: Dan Manis, P.E., Village Engineer, manisd@wilmette.com or 847-853-7602

Background

The Village of Wilmette performs annual maintenance, including cleaning and televising, on the approximately 160 miles of sanitary, storm and combined sewer systems owned by the Village. Routine cleaning is a vital component of maintaining the existing sewer system to its maximum effectiveness and capacity. Through the televising, the program allows the Village to evaluate the sewer condition and identify deteriorated segments of the sewer main that need repair.

The sewer mains are typically maintained on a 7-year cycle. Sewers are on a cleaning rotation by basin. The Village also focuses on areas experiencing poor system performance as well as sewers that are on the sewer lining program and the annual road program. This allows defects to be identified and addressed through the annual sewer repair program, minimizing future disruptions to new pavement.

In 2022, the Village Board approved an additional $20,000 to televise large diameter relief sewers and trunk lines to maintain these critical assets.
