A major sewer system evaluation survey is nearing completion in the seven communities which make up Special District No. 1 of the East Bay Municipal Utility District. A major effort has been made to conduct a meaningful inventory directed at determining the condition of each community's sanitary sewage collection system. While the impetus for this gigantic effort has been the elimination of system overflows through the reduction of infiltration and inflow, the study has determined that overflows are largely the consequence of system deterioration, not illegal connections. Many investigative tools and techniques have been used to assess the condition of the sewers. A computerized management information system has been developed to handle the massive amount of data generated.
