3.2.8 SGC-C-0003 (Essen Lane - Interstate 12)
The SGC-C-0003 (Essen Lan – Interstate 12) project has been combined with SGC-C-0002
(Airline Highway - Jefferson Highway) project and SGU-C-0002 (Airline Highway -
Interstate 12) project from the October 2008 PDP. The combined project has been designated
SGC-C-0002 (Airline Highway Pipeline Improvements) project, and is described in Section
3.2.7.
3.2.9 SGC-C-PS58A (Pump Station 58 Replacement)
Project Description
Purpose of the Project/Project Background
The SGC-C-PS58A (Pump Station 58 Replacement) project includes the construction of a
new overflow pump station pump station (PS 58) that will handle the existing flow
conditions and the predicted future wet weather peak flow. The design of a single pump
station was selected as the best design option to meet the long-term needs of the C-P and the
sensitive environmental and aesthetic concerns of the surrounding area. (
The purpose of this project is to relieve SSOs at PS 58 as well as in the respective upstream
and downstream basins. This project is related to SGC-C-PS58FM-A (Staring Lane FM Phase
I – Burbank to Highland), SGC-C-PS58FM-B (Staring Lane FM - Phase II – Highland to
Perkins), and SGC-C-PS58FM-C (Staring Lane FM - Phase III – Perkins to PS58) which
involve the construction of the forcemain from PS 58 to the South WWTP.
Location
The project site and existing PS 58 are located at the entrance of the Louisiana State
University Burden Center. The location of PS 58 is shown in Table 3-6 and in Figure 3-17.
Scope
The current PS 58 will not have enough pumping capacity to handle the predicted future
wet weather peak flow. PS 58 shall be replaced with a pump station that will handle both
the existing flow conditions and future wet weather peak flow conditions. The pump station
will pump flow into the downstream gravity system when flows do not exceed 20,870 gpm.
When flows exceed 20,870 gpm, the pump station will pump the excess flow directly to the
South WWTP. The proposed scope is shown in Table 3-6.
