Problem: The Big Cottonwood Water Treatment Plant at the mouth of the Big Cottonwood Canyon is one of three water treatment facilities serving Salt Lake City, Utah, via 1,300 miles of transmission and distribution pipe. The plant implemented a bulk hypochlorite system in 2003. After seven years on that system, utility leaders chose to switch to on‐site hypochlorite generation for safety and cost savings.
Solution: The plant staff selected two 600-pound-per-day (1,200 pounds of chlorine equivalent) Microclor on‐site hypochlorite systems from Cleanwater1. Modular multi‐cell systems in a vertical configuration vent byproduct hydrogen passively with no chance of pressurization.
Result: The systems generate
