Sewer Line Improvements Project
Overview:
The sewer main improvements include replacing approximately 4.1 miles of existing 6, 8, 10, and 12-inch vitrified clay, asbestos cement, and high-density polyethylene pipes at twenty-nine locations throughout the City. Approximately 3.3 miles of sewer main will be replaced by traditional open-cut method constructed in segments to minimize the impact to customers and traffic. The remaining 0.8 mile will either be rehabilitated or replaced by trenchless pipe techniques including microtunneling, pipe bursting, pipe reaming, or cured-in-place pipe (CIPP), where open-cut installation is not recommended due to surface features. This project also includes installation of new manholes in areas where it is often difficult to access the existing manholes located in easements on residential properties. The goal of the project is to improve capacity and maintain operability of the sewer collection system while improving accessibility for future maintenance.
Project Locations:
Sewer line locations were selected by staff based on performance and maintenance data over the past several years. Recommended projects from the 2015 Sewer Master Plan, including upsizing undersized sewer mains, rerouting flows, and installing new sewer lines, were also incorporated to address capacity deficiencies within the existing sewer collection system.
