Sewer Group 3 Small Diameter Rehabilitation: Contract B
PROJECT OVERVIEW
The purpose of the Sewer Group 3 Small Diameter Contract B is to upgrade the City’s existing small diameter sewers. This work will remedy defects observed during the Sewer System Evaluation Survey (SSES) and will reduce the amount of extraneous flows, infiltration, and inflow entering the system, as well as eliminating sanitary sewer overflows (SSOs). Rehabilitation will extend the life of the sewer 50 + years while meeting the requirements necessary to comply with the First Amended Consent Decree.
WHAT KIND OF WORK WILL BE PERFORMED?
The City uses various techniques to repair old deteriorated sewer lines. The scope of this project involves the use of various “trenchless technologies” including Cured- in-Place pipe (CIPP) lining and Pipe bursting, as well as a more traditional method of repair such as open-cut/replacement, will also be utilized. In addition, pre-cleaning of the sewers will take place, point repairs will address localized pipe defects, and manholes will be rehabilitated.
WHAT ARE THE BENEFITS OF THE PROJECT?
Structural upgrades to the system are necessary to replace old and deteriorated sewers in order to maintain the reliability of the sewers. Rehabilitation of the sanitary sewers reduces the amount of extraneous flows, infiltration, and inflow (I/I) entering the system, in addition to reducing the amount of untreated sewage flowing into streams and creeks as a result of sanitary sewer overflows.
WHO WILL BE IMPACTED?
This is a defined scope project. The City will be working within sewersheds LICB, PTC-PRC02, PRC17_18B, PRC13, PRC13BZ, PRC13A1, SDC01A, SDC03A, SDC03, SDC03B, SDC03B1, PRC05C, PRC05C1, PRC05B and PRC15. The work affects Council Districts 3, 8, 9 and 10. Disruption of service, partial/temporary lane and road closures, work on private property and noise may occur as a result of construction. However, we will notify impacted residents and businesses through mailings, door hangers or face-to-face prior to work starting in the area. City representatives also will attend NPU’s and community meetings to discuss planned work and provide periodic updates.
HOW LONG WILL THIS TAKE?
Construction is anticipated to last approximately one year. While work is taking place, we will make every effort to minimize any impacts on residents and business owners.
