The City of Baton Rouge/Parish of East Baton Rouge (City/Parish) has contracted with CH2M HILL to prepare a Program Delivery Plan (PDP). This PDP provides a summary of the Sewer System Overflow (SSO) and Wastewater Facilities Program. The three parts of the program are:
This PDP describes a total of 82 wet weather projects to be constructed by January 1, 2015 at an estimated total program cost of $1.2 billion in 2007 dollars. These costs include the construction, design engineering, construction engineering and management, and program management. There are three additional projects previously undertaken by the C-P, which will be included in the Program for a total of 95 projects. Those additional projects are the Remedial Measures Action Plan (RMAP1) projects.
The goals of the program include the following activities:
- Reduce excess wet weather flows that cause SSOs
- Rehabilitate the collection system
- Increase the hydraulic capacity of the collection system
- Accommodate growth in project areas
- Comply with wastewater treatment plant National Pollutant Discharge Elimination System (NPDES) permit
- Comply with the terms of the Consent Decree
In the preparation of the PDP, the locations of known overflows are given highest priority in order to reduce the frequency of these overflows. Areas of the collection system that were found to have excessive levels of infiltration or inflow were identified for rehabilitation.
Hydraulic capacity improvement projects are sized to accommodate predicted peak wet weather flows and anticipated growth in the project areas. Peak wet weather flows were predicted based on a 2-year frequency, 12-hour duration previously selected design storm.
