Program Delivery Plan

SECTION 1. OVERVIEW
1.3.2 Capacity Improvement Projects
Capacity improvement projects will reduce hydraulic bottlenecks in the system and convey
wet weather flows to new upstream storage facilities and ultimately to the wastewater
treatment plants (WWTPs). These projects will include installation of larger pipes or
constructing parallel pipes to increase conveyance capacity, as well as replacement of pump
stations to handle future wet weather peak flows.
1.3.3 Wastewater Treatment Improvement/Storage Projects
Design and construction of WWTP wet weather improvement projects will occur early in
the program to store and treat wet weather flows. Wastewater treatment projects at the
South WWTP include the following:
Immediate Action Projects (IAPs) for dry weather permit compliance
Consolidation with the Central WWTP (Refer to the Consolidation of South and Central
Wastewater Treatment Plants in Baton Rouge TM (CH2M HILL, 2008)
Wet weather flow capacity increases to 200 million gallons per day (mgd) with hydraulic
peak shaving
Master Plan improvements
The South WWTP immediate action projects and other South WWTP projects are included
in this document and are part of the RMAP2 projects. However, the South WWTP Phase 2
Master Plan project is described in a separate document (Draft Master Plan; CH2M HILL,
2008), though its construction cost estimate is included in the Preliminary Master Plan
Section of Table 1-1. There are not any capacity improvements required at the North WWTP,
so there are no wet weather (RMAP2) projects included in this report at the North WWTP.
However, there are several improvements needed due to the age of the treatment plant
which are briefly described in the Section 5 - North Basin chapter of this report. The Draft
Master Plan (CH2M HILL, 2008) also describes in detail the needed improvements in two
priorities at the North WWTP.
Storage projects will be designed and constructed early in the program to store wet weather
flows upstream in the basins and then release flows back into the system after the wet weather
event has passed. Storage facilities will be sized to store the peak flow from a 2 year
frequency, 12-hour duration storm event, assuming rehabilitation projects are complete.
1.4 Project Delivery Summary
The projects have been scheduled for both design and construction activities based on
funding considerations, and placed into a resource-loaded schedule shown in Table 1-1 and
depicted graphically as Figure 1-1. Figure 1-2 presents the schedule for pre-construction and
construction activities for all the program projects.
Note: Financial analysis and funding schedules are prepared by the C-P DPW and are not
a part of this document.
