STRATEGIC ELIMINATION OF SSOs: OPTIMIZATION MODEL SUPPORTS DISTRICT-WIDE CAPITAL IMPROVEMENT PROGRAM
Abstract:The typical Capital Improvement Program (CIP) for a sanitary sewer collection system consists of a combination of collection system rehabilitation, conveyance improvements, and can potentially include storage and treatment facilities. According to the proposed SSO regulations, a System Evaluation and Capacity Assurance Plan (SECAP), that outlines required engineering activities and includes a CIP, will be necessary to bring a sanitary sewer collection system into compliance. However, for medium to large size collection systems, it is difficult to comprehensively optimize improvements using standard cost-effective analysis. This paper presents an optimization model that supports a system-wide CIP for an aggressive Sanitary Sewer Overflow (SSO) Elimination Program for the Vallejo Sanitation and Flood Control District in California.
