SECTION 4. CENTRAL BASIN PROJECTS
4.2.4 CGN-C-0004 (Downtown Area –PS 59 Improvements)
The CGN-C-0004 project has been combined with CGN-C-0005 (Downtown Area - PS 15, PS
19, PS 59, and PS 60 Improvements) from the October 2008 PDP. The combined project has
been designated CGN-C-0005 (Downtown Area Pump Station Improvements) and is
described in Section 4.2.5.
4.2.5 CGN-C-0005 (Downtown Area Pump Station Improvements)
Project Description
Purpose of the Project/Project Background
The CGN-C-0005 (Downtown Area Improvements) project includes the upgrade of PS 15, PS
19, and PS 59 to alleviate SSOs at and near the PSs as well as in their respective upstream
basins. This project is the combination of CGN-C-0005 (Downtown Area – PS515, PS519, and
PS 59 Improvements) and CGN-C-0004 (Downtown Area – PS 59 Improvements) from the
October 2008 PDP. The combined project has been designated CGN-C-005 (Downtown Area
Pump Stations) and is described in the rest of this section.
The BTRSSO hydraulic model also predicts a PS capacity exceedance for the future peak wet
weather flow. PS 15, PS 19, and the existing PS 60 will utilize the new forcemains outlined in
the project CGN-C-0001 (Capital Lake Drive – Gayosa Street). PS 59 was added to this
project in 2009 because of the similarity of the project and proximity to the other pump
stations included in this project. During design, it was discovered that PS 59 could be
rehabilitated by installing new pumps rather than completely replacing the entire pump
station.
Location
The locations of PS 15, PS 19, and PS 59 are given in Table 4-4 and in Figure 4-12.
