PROJECT GOALS, ACHIEVEMENTS, AND BENEFITS
McGovern McDonald Engineer’s principal, Steve McDonald, was Project Manager for the development of an asset condition assessment for the City of Stockton, CA Wastewater Treatment Plant. The purpose of this condition assessment was to establish a starting point “baseline” that was to set the return value for a privatization contract with OMI/Thames Water for the City’s wastewater system. This was a multi-discipline engineering team field inspection involving all major wastewater treatment plant assets and upstream wastewater pump station facilities. Several unique approaches were taken to address issues of concern to both the City and OMI. These issues required innovative approaches including expanding the definition of the “end state” asset condition to include functionality in addition to assessed valuation.
Development of a Low Impact Development (LID) Life Cycle Cost Benefit model that determines the costs and benefits of stormwater measures to both the customer and for the SFPUC.
Assessed the methylation potential and bioavailability of mercury discharged from point sources for the Water Environment Research Federation (WERF).
Identified stormwater and recycled water cost and benefits to the customer and SFPUC with implementation of LID techniques.
Development of stormwater best management practice O&M life cycle costs for street installation as part of the San Francisco Better Streets Plan.
Provided NPDES regulatory and permitting support for treated wastewater and stormwater discharges and Combined Sewer Overflows (CSOs) to the Bay and Pacific Ocean.
Development of a modeling tool for States and NPDES permit holders to assist nutrient management strategies for the Water Environment Research Federation.
Reviewed NPDES stormwater documents for transfer from private to SFPUC authority and recommended future monitoring program improvements for the SFPUC’s Mission Bay Development.
