Background
Water maintenance staff discovered a consistent valve isolation problem that had degraded over a number of years while performing maintenance at the Novelty Hill Pump Station and the Novelty Hill Operations Center Tank site. The City maintains 65 Butterfly Valves to isolate sections of the piping within the facilities. These valves range in size from 8-inches to 24-inches. These Butterfly Valves had degraded to a point that they could not form a water-tight seal when closed because the rubber valve seats were crumbling away, making it very difficult for the MOC staff to isolate parts of these facilities. During the initial investigation of the problem staff employed a corrosion expert to evaluate the condition of the valves and pipe in both facilities. The results of this evaluation revealed consistent corrosion of the pipe spools as well as failure of the val...
