This article discusses the addition of ozone generation facilities at the 770‐mgd Wylie, Texas, Water Treatment Plant (WTP) complex that will more effectively disinfect drinking water, reduce chlorination disinfection byproducts, and control taste and odor. Ozone will be added to the treatment process using sidestream injection systems at the head of ozone contact basins. Any residual ozone remaining at the end of the contact basins will be quenched using calcium thiosulfate. The article discusses the challenges associated with adding ozonation facilities to an existing water treatment complex consisting of four interconnected water treatment plants (plants 1, 2, 3, and 4) on a 442‐acre site. Because of the complexities of multiple water treatment plants, multiple raw water intakes with differing raw water characteristics, and varying water demands in each plant, the district will use a hybrid constant‐concentration control logic to operate the ozone facilities.
