Engineering Department Sanitary Sewer Mission: To provide continuous operations and maintenance of the City of Richmond Municipal Sewer District conveyance system for domestic, commercial and industrial wastewater in the Richmond area of Contra Costa County Overview: Sewer Drain Improvements The Wastewater program of the Engineering Division is to Rehabilitate and provide preventative maintenance to the subsurface network of pipes and conduits. This division is also responsible for ensuring compliance with the City s Wastewater Discharge Permit (Order No. 01-144, NPDES permit CA0038539) issued by the Regional Water Quality Control Board San Francisco Bay Region. The related appurtenances include more than 250 miles of underground pipes and remote sanitary sewage life stations and an FM telemetry system. This program is organized via a 20-year contract with Veolia Water North America under the direction of the City Engineer. Treatment Plant The majority of funds in the Sanitary Sewer System Capital Program are used to construct sewer improvement projects. Construction projects in the Proposed CIP fall into one of two categories: (a) enhance sewer capacity in substantially built-out areas and/or less developed areas; or (b) rehabilitate existing sewers, with higher priorities given to those with extensive, severe deterioration. A project that will enhance capacity and rehabilitate existing sewers is considered a rehabilitation project for the purpose of this budget. Emphasis is placed on larger lines within each category.

Program Highlights Sanitary Sewer Collections San Pablo Ave/Solano & Bissell Avenues FY2006 - FY2008 The long-term goal of this project is to prevent bottlenecking in the sanitary sewer system. This will be accomplished by increasing the pipe size to prevent the possibility of exceeding the systems hydraulic capacity, which could result in a Sanitary Sewer Overflow. (Program Cost $1,566,000) Sanitary Sewer Manhole Rehabilitation FY2006 - FY2011 This is an on-going project over a 10 year life cycle, which will be funded by the Wastewater Bond. The purpose of this project is to remedy the existing problems of deteriorated manholes which could result in Inflow and Infiltration in the collection system. (Program Cost $552,700) Harbour Way South @ Hall Ave & Marina Way South Tidal Groundwater Infiltration Rehabilitation Project FY2006-FY2007 This area has been identified as a main source of tidal inflow and infiltration (I&I) as indicated in the Wet Weather Flow study. (Program Cost $1,500,000) First Street between Cutting Blvd and Macdonald Avenue FY2007 - FY2008 This area has been identified as a hot-spot for sanitary sewer problems (back-ups, bottleneck, etc.), as indicated from the Closed Circuit Televising [CCTV] (Program Cost $2,500,000) I-580 Freeway @ Castro Street FY2006 FY2007 This area has been identified as a hot-spot for sanitary sewer problems (back-ups, bottleneck, etc.) (Program Cost $1,000,000) Performance Measures A set of performance measures have been designed to set goals and meet target dates. The performance levels established are for Wastewater s Capital program. There is also contract language with milestones and deadlines for completion. Completion of Capital project within two (2) months of the approved schedule; Keep the budget costs for the Capital projects within the adopted budget; Better project delivery costs for construction costs; Contract language milestones; The sanitary sewer collection system s priority is always to comply with all local, state and federal Regulatory Agency requirements. This will be accomplished by Staff participating in off-site conferences, trainings, and workshops. E-2
