Section 1. Project Overview/Background

This project is part of an overall plan for new water transmission mains to be constructed to create a water transmission loop that will provide redundant water service to GLWA customers currently served off a single, non-looped transmission main.

The downriver communities of Riverview, Brownstown Township, Trenton, Woodhaven, Grosse Ille Township, Gibraltar, Flat Rock, Rockwood, South Rockwood, and Berlin Township are serviced off a single feed main serviced from the Southwest Water Treatment Plant along Allen Road. The purpose of this project is to provide redundancy to these ten communities by constructing a new main along Inkster Road between Wick Road and Pennsylvania Road.

Under this project, approximately 20,800 linear feet of new 42-inch diameter transmission main will be constructed to connect to the 48-inch diameter pipeline at the intersection of Wick Road and Inkster Road and the 30-inch transmission main at the intersection of Inkster Road and Pennsylvania Road. The project also includes the demolition of the Electric Avenue Pump Station’s two (2) reservoirs in Lincoln Park, improvements to existing metering facilities in Trenton (TN-01), and construction of a new interconnection with Taylor near the intersection of Inkster and Northline Roads.

The Scope of Work is described in Exhibit A of Attachment No. 1 and Specification Section 01 11 00 Summary of Work.
