Abstract

This chapter presents a post-rehabilitation monitoring and modeling study of the sanitary sewer system at Lawrence Livermore National Laboratory (LLNL). The study evaluated effectiveness of sewer system rehabilitation efforts and defined benchmarks for environmental success. A PCSWMM model for the sanitary sewer system was developed and applied to demonstrate the success of a $5 million rehabilitation effort. It determined that rainfall-dependent inflow and infiltration (RDI&I) had been reduced by 88%, and that system upgrades adequately manage computed peak flows. An ongoing modeling and analysis program currently assists management in evaluating the system's needs for continuing maintenance and further upgrades. This chapter also summarizes a 1989 study that evaluated data collected from December 1, 1988, to January 6, 1989, to determine the adequacy of the LLNL sewer system to accommodate present and future peak flows, and the Sanitary Sewer Rehabilitation (SSR) project, which took place from 1991 through 1995.
