water storage tanks with capacities of 3 million <br />gallons each. Three tanks were constructed of <br />concrete with diameters between 100 feet and <br />144 feet and heights up to 110 feet above <br />ground. One tank was an elevated steel tank <br />supported by multiple columns. The tanks were <br />constructed between 1937 and 1961. V&A <br />developed an industry -accepted scoring and <br />ranking methodology to prioritize repair and <br />replacement work to the water storage <br />reservoirs. The methodology will be used by the <br />City of Sacramento on steel and concrete <br />reservoirs to determine the condition of the City's <br />water infrastructure and will be used to prioritize <br />planning studies, rehabilitation and replacement <br />projects, and preventative maintenance <br />scheduling. V&A performed interior assessments <br />while the tanks were filled with water with use of <br />a raft. V&A provided repair recommendations <br />with budgetary cost estimates. <br />[2.2018 1 15-0382 1 w] <br />San Jose Water Company Swelgert <br />Station Reservoir Cathodic Protection <br />System Design. San Jose, CA <br />V&A designed a galvanic anode cathodic <br />protection (CP) system for the submerged interior <br />of San Jose Water Company's (SJWC) Sweigart <br />Station Reservoir. Due to constraints set forth by <br />SJWC, V&A was required to design a custom CP <br />system featuring horizontal anodes suspended <br />from anchors welded to the interior walls of the <br />tank. V&A submitted drawings and technical <br />specifications for the CP system detailing the <br />number, size, location, and material of galvanic <br />anodes required to provide corrosion control to <br />the reservoir. [7.2016 1 16-0106 1 w] <br />Western Municipal Water District Cathodic <br />Protection Monitoring Services. Riverside, CA <br />V&A conducted a corrosion assessment of the <br />District's pipelines and reservoirs by measuring <br />structure -to -electrolyte potentials at available <br />test stations. The potentials measured on non- <br />cathodically protected pipelines and reservoirs <br />were evaluated to determine if the structures <br />were actively corroding. The potentials measured <br />on cathodically protected pipelines and <br />reservoirs were compared to NACE criteria for <br />corrosion control to determine if corrosion of the <br />structures had been mitigated. V&A presented a <br />report summarizing the results of the <br />assessment and presented recommendations for <br />s , <br />,. i <br />future maintenance and testing of the structures. <br />[7.2016 1 14-0367 1 w] <br />City of Modesto, Del Rio Water Tank and <br />Transmission Pipeline. Modesto, CA <br />Reviewed water quality analysis and soil sample <br />resistivity testing and chemical analysis to <br />determine the corrosivity of the water and soil <br />towards a 250,000-gallon welded steel water <br />tank and a 16-inch diameter cement -mortal lined <br />and coated steel transmission pipeline. Provided <br />recommendations for corrosion control, including <br />coatings, lining, and corrosion monitoring. Based <br />on the water and soil conditions, cathodic <br />protection was not recommended. <br />[11.2018 1 17-0194 1 w] <br />San Jose Water Company Chelm Reservoir <br />Cathodic Protection System Design. San Jose, CA <br />V&A designed a galvanic anode cathodic <br />protection (CP) system for the submerged interior <br />of San Jose Water Company (SJWC) Chaim <br />Reservoir. Due to constraints set forth by SJWC, <br />V&A was required to design a custom cathodic <br />protection system featuring horizontally oriented <br />anodes suspended from anchors welded to the <br />interior walls of the tank. V&A submitted <br />drawings and technical specifications for the <br />cathodic protection system detailing the number, <br />size, location, and material of galvanic anodes <br />required to provide corrosion control to the <br />reservoir. [3.2016 1 16-0030 1 w] <br />Cucamonga Valley Water District Reservoir 3C-2 <br />Condition Assessment. Rancho Cucamonga, CA <br />V&A was retained for condition assessment <br />services to support the Cucamonga Valley <br />Water District Reservoir 3C-2. The CA included <br />assessment of field conditions, report of <br />findings, alternatives and recommendations <br />for rehabilitating the structural steel members <br />and managing corrosion in the future for a <br />16-million-galion pre -stressed concrete reservoir <br />at the Lloyd W. Michael Water Treatment Plant. <br />[8.2015 1 15-0084 1 w] <br />RICHARD BRADY &ASSOCIATES, INC. E-48 <br />
