Sewer Lining Phase 5

 

Contractor: TBD

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

Background

The Village of Wilmette has an annual sewer lining program to rehabilitate its aged sewer system.  Sewer lining uses a cured-in-place pipe (CIPP) as a non-invasive, cost-effective technique to repair and rehabilitate underground sewers. Sewer lining restores the structural integrity of the pipe and reduces stormwater infiltration through sealing open pipe joints, areas of root intrusion and cracks. Sewer lining is not only less disruptive because it allows the work to be completed without excavating the roadway, but the work can also be completed in one day rather than over an extended period with conventional methods like removal and replacement. The service life of CIPP is approximately 50 years.

This annual expenditure is proposed to be a long-term program to address the deterioration of the Village’s sewer system. Historically, the Village has sought low interest financing through the IEPA State Revolving Fund (SRF) to complete the sewer lining program. The Village currently has approval for a five-year facility plan to complete the sewer lining in phases. The first phase of the plan was completed in 2016 with the final phase scheduled to be completed this year.
