This project consisted of the replacement of the fluoride, phosphate, and sodium hypochlorite chemical feed systems with in-kind replacement of the bulk tanks, day tanks, transfer pumps, and metering pumps, as well as new piping and appurtenances for each of the chemicals. The project also included installing a new sodium hydroxide chemical feed system, including a bulk storage tank with a fill system, day tank, transfer and metering pumps, and associated piping and appurtenances. Additionally, several upgrades to the building include replacing the exhaust fans, unit heaters, and emergency eyewash/shower.
