2020 Sewer Cleaning and Televising Program

Contractor: American Underground, Inc.

Project Contact: Danielle Horn, P.E., Project Manager, hornd@wilmette.com or 847-853-7628

Background

The Village of Wilmette performs annual maintenance, including cleaning and televising of the sanitary, storm and combined sewer systems. 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 almost 160 miles of sewer main throughout the Village are maintained on a 10-year cycle. Sewers are on a cleaning rotation by basin. The Village also focuses on sewers that are on the annual road program to minimize future disruptions to new pavement, as well as areas experiencing poor system performance.

In 2020, the Village Board approved an additional $50,000 to televise large diameter relief sewers and trunk lines to maintain these critical assets.
