Liquid Oxygen 2026

Project Description: City Public Utilities Department, and others. Metro Water owns and operates two (2) water treatment plants, the Little Cottonwood Water Treatment Plant (LCWTP) and the Point of the Mountain Water Treatment Plant (POMWTP), (collectively called the Treatment Plants). The Treatment Plants have full conventional treatment. Liquid oxygen is used during on-site production of ozone gas. Ozone gas acts as a primary disinfectant in the treatment process and also provides positive aesthetic benefits in the finished water. Both Treatment Plants have different volume requirements for liquid oxygen. Some physical differences between Treatment Plants exist with respect to the storage and use of liquid oxygen. The LCWTP has two (2) 21,000-gallon storage tanks; one (1) tank is in service. The POMWTP has one (1) 13,000-gallon storage tank. All liquid oxygen tanks are owned by Metro Water.
