SECTION 4. CENTRAL BASIN PROJECTS
4.2 Central Gravity System Capacity Improvements Projects
4.2.1 CGN-C-0001 (Capital Lake Drive – Gayosa Street Area Capacity
Improvements)
Project Description
Purpose of the Project/Background Information
The purpose of this project is to re-route flow from PS 15 and PS 19 so that they directly
pump through a common forcemain and manifold with the forcemain from PS 60 to
increase the capacity of the system. The forcemain then discharges wastewater into the
gravity system at the existing manhole (MH# 059-05885) located at the intersection of River
Road and Capital Drive. The October 2009 version of the PDP add the construction of those
gravity segments originating at the intersection of North Acadian Thruway and Ontario
Street, and the intersection of Washington Avenue and West Belfair Drive, both terminating
at PS 15, that were originally part of CGN-C-0002 (25 th Street-North Acadian) project to
improve constructability and scheduling issues. Information about those segments has been
included in this section.
Location
The locations of forcemains and gravity sewers in this project are shown in Figure 4-10.
Forcemain segment PS 15FM to PS 15DS (manifold point of PS19 and PS15 forcemain) starts
south of the Washington Ave and West Belfair Drive intersection. The forcemain travels
west until reaching North Acadian Thruway. The forcemain then turns in a northerly
direction until reaching the intersection of North Acadian Thruway West and Madison
Avenue where the forcemain turns in a westerly direction, and continues until reaching
Eiland Street. On Eiland Street, the PS 15 forcemain will be manifolded at PS 15DS with the
forcemain exiting PS 19.
Forcemain segment PS 15DS to PS 60 travels west along Eiland Street until reaching 3 rd
Street and then travels south to PS 60 along River Road where it is manifolded with the PS60
forcemain at PS60DS
Forcemain segment PS 60DS to 059-05885 travels south from PS 60 on River Road to
manhole 059-05885, which is located on River Road at the intersection of State Capitol Drive
and River Road.
Gravity segment 060-07642 to 060-07619 starts at the North Acadian Thruway West and
Ontario Street intersection. The gravity segment travels south until reaching 060-07619, near
the North Acadian Thruway West and Baron Street intersection.
Gravity segment 060-07619 to 060-07544 travels south until reaching 060-07544 located near
the North Acadian Thruway West and Fairfields Avenue intersection.
Gravity segment 060-07544 to 060-07529 travels south until reaching 060-07529 located near
the North Acadian Thruway and Washington Avenue intersection. Gravity segment 060-
07529 to PS15 travels east until reaching PS15.
Gravity segment 060-07529 to PS 15 travels east along Washington Avenue until reaching PS
15, located south of the Washington Avenue and Belfair Drive intersection.
