Project Overview

Due to inappropriate connections, defective pipe joints, and broken pipes, there is currently an increased amount of flow (inflow and infiltration) being sent to and treated by the wastewater treatment plant during a storm event. This results in a higher risk of sanitary sewer overflows, as well as increased costs to pump and treat the sewage. In addition, recent water conservation efforts have reduced the flow in some areas of the system, causing solids to build up and clog the sewers.

The project consists of replacing the existing 6-inch and 10-inch diameter sanitary sewer mains (“mains”) located in both public right-of-way and public utility easements (which are mostly in the backyards of residences) with new 8-inch and 12-inch diameter mains respectively. A map of the proposed sanitary sewer improvements (indicating proposed improvements through residential backyards) can be found by clicking the link at the bottom of this page. The increase in main size will help prevent the buildup of solids and will facilitate easier cleaning and maintenance of the pipes.

To reduce the impact on the surrounding neighborhood, the project will primarily involve replacing the pipes using the pipe bursting method. Pipe bursting allows for trenchless installation, reducing the amount of disturbed area. Small excavations will be necessary on one or both sides of existing manholes to begin and end the pipe bursting process. Small open excavations will also be necessary to re-connect each existing sewer lateral to the associated new main. Rehabilitation and replacement of sanitary sewer manholes will be completed as necessary.

The first community meeting was held on November 2, 2017 with the purpose of introducing the project to Pedro Point residents. On March 1, 2018, a second community meeting took place to inform residents of the lateral replacement cost and provide more information about the project.

Project construction began April 2018 and has been completed April 2019.
