Located at the mouth of the Big Cottonwood Canyon, the Big Cottonwood WTP is one of three water treatment facilities providing treated water to Salt Lake City (SLC), Utah. The utility distributes water through about 1,300 miles of transmission and distribution pipe to over 90,500 connections. Recently, the Big Cottonwood WTP was recognized for delivering 16 years of high-quality water and received the Directors Award from the EPA & AWWA Partnership for Safe Water.
The original treatment plant was constructed in 1957. In the 1980’s, the plant was renovated to treat 42 MGD (roughly 40 percent of the water treatment capacity for SLC) and a gas chlorine system was installed for
disinfection.
