This phase included hazardous waste facility improvements and other safety related items within the treatment plant facilities. 7314 Treatment Plant Urgent Repairs Urgent treatment plant work which requires immediate repairs arise at any time, some cannot be completed by maintenance staff or wait for incorporation into a capital improvement project. This project encompassed miscellaneous areas around the plant and were triggered by equipment or process piping failures; compliance with regulatory or code issues; and/or safety or unexpected damage due to excessive or unexpected hazards. Staff intended to procure a standby contractor to perform such activities; however, due to the lack of outside interest and the current bid environment staff decided to assign this scope of work to the Treatment Plant Piping Renovations Project-Phase 9 and other projects within the Treatment Plant Program. 7319 Laboratory Upgrades and Repairs The laboratory is a critical component to regulatory reporting and operates several critical systems to maintain the facilities required to conduct testing. This project included work to address corroded hot water heat exchangers and tanks; obsolete and outdated HVAC control systems; replacement of a 150-ton roof chiller, including structural support modifications; and improved electrical and mechanical controls to the chiller and HVAC system COLLECTION SYSTEM PROGRAM Project No. Project Title 5941 Pump Stations Equipment and Piping Replacement The purpose of this project was to replace or recondition various failed and obsolete equipment, provide for proper emergency response at the pumping stations, and to meet new regulatory requirements. This project included the addition of appropriate control and isolation valves for shutdown and station protection; station and equipment flood protection; reconditioned major pieces of equipment to original factory specifications; purchased spare assemblies needed for pump station equipment; and investigated pump-around capabilities. 8417 Survey Monument Install The Survey Monument Installation project consisted of the installation/replacement of survey monuments which were removed during sewer renovations. This project provided staff with the contracted resources necessary to fulfill the professional and legal obligations that the survey monuments provide. 8420 Development Sewerage The purpose of this project was to provide for capitalization of labor for Central San forces and other expenses associated with developer installed sewer facilities. A portion of the revenue collected from these development projects is credited to the Sewer Construction fund to offset some of the expenditures made under this capital project.

Sewer improvements that were identified to be completed under this repair program included sewers that were in poor condition and beyond repair that could not be incorporated into another capital project. This includes assessments made by failed sewers during routine cleaning, failed or damaged sewers by unexpected hazards or events, and safety or site hazards that posed a serious threat to the integrity of the collection system infrastructure. Staff intended to procure a standby contractor to perform such activities; however, due to the lack of outside interest and the current bid environment staff decided to assign this scope of work to other projects within the Collection System Program. 8437 Martinez Sewer Renovations Phase 5 This project replaced and renovated approximately 8,800 feet of existing sewers and infrastructure and 43 new or replaced manholes located in easements, public rights-of-way. Most of the sites were located south of Highway 24 in the Martinez area. 8439 Miner Road Sewer Repairs 2017 This emergency project was due to sewer failures caused by the significant rain events in February of 2017. A large sinkhole engulfed two sewers on Miner Road in Orinda. These sewers were repaired, and all work was coordinated with the City of Orinda and other agencies to restore the roadway. GENERAL IMPROVEMENTS PROGRAM Project No. Project Title 8227 Geographic Data Integration (GDI) Treatment Plant The GDI Treatment Plant project implemented a geographically based asset management system for the treatment plant. This tool will optimize the interface and functionality accessing the asset data. After successful implementation of the collection system GDI, the treatment plant GDI will provide efficient access to asset drawings and data. RECYCLED WATER PROGRAM Project No. Project Title There were no Recycled Water projects closed in Fiscal Year 2017-18.
