A Brief History

In 1972, the U.S. Congress implemented the Clean Water Act (PL 92-500) to “restore and maintain the chemical, physical, and biological integrity of the nation's water.”  In 1978, the Central Valley Water Reclamation Facility Board (Central Valley) was organized as an Inter-Local Agreement Agency.  Members of the Board represent five special service districts and two cities which owned and operated wastewater collection systems and five small treatment plants. 

Central Valley’s member agencies are listed below and links to their websites are provided under the “Collection Agencies” Tab.

  • Cottonwood Improvement District
  • Granger-Hunter Improvement District
  • Kerns Improvement District
  • Mt. Olympus Improvement District
  • Murray City
  • South Salt Lake City
  • Taylorsville-Bennion Improvement District

Central Valley Member Agencies

The new Board’s mission was to replace the five small antiquated wastewater treatment plants that could not meet the requirements of the new law with a new regional treatment plant that would treat the wastewater from all the member entities.  The new treatment plant was designed and constructed from 1981 to 1987 and is called the Central Valley Water Reclamation Facility. The discharge from the facility is permitted under the Utah Pollution Discharge Elimination System (UPDES) - Permit UT0024392.

The facility was constructed with a combination of U.S. EPA Construction Grants and local funds.  The facility underwent major expansion and improvement projects in 1994, 2001, and 2005 to add both liquid and solids treatment capacity.  In 2010, the facility made a major process change to eliminate the use of liquefied chlorine gas for effluent disinfection.  With this project, the original chlorine contact process was replaced with a much safer ultraviolet light (UV) disinfection process.

Currently, major process changes and facility improvements are being designed which will be constructed and in service by 2025.  These improvements are in response to aging infrastructure issues of the original plant which is now 30 years old, and a new rule from the State of Utah Division of Water Quality (DWQ) governing discharge of phosphorus, a nutrient that stimulates growth of plants and algae.  Central Valley’s treatment process will be upgraded to a state-of-the-art biological nutrient removal (BNR) process and all major mechanical and electrical system will be rehabilitated or replaced, so that the facility can successfully serve the public for the next 30 years.

Central Valley Water Reclamation Facility is located at 800 West Central Valley Road (3190 South) in South Salt Lake City.  Central Valley was built on property owned by one of the centrally located member entities.  Central Valley's entire property covers 168 acres.  The treatment facility itself is 85 acres and is surrounded by the Central Valley Golf Course and Golf in the Round Driving Range which are owned by the facility and operated by a private golf management company. 

Because wastewater never ceases to flow, the treatment plant operates 24 hours a day, 7 days a week, 365 days a year.  Designed and built to treat 75 million gallons of wastewater each day, Central Valley serves over 500,000 people in the Salt Lake County area.  The facility employs 90 dedicated employees.
