Roy Water Conservancy Subdistrict originated on February 16, 1965. Construction on the Subdistrict infrastructure began in 1974 and was finished in 1977. The Subdistrict was built as a small reclamation project by the U.S. Bureau of Reclamation through the Small Reclamation Loan Act. Initial federal funding for the Subdistrict infrastructure was $8,400,000 and now has a present value in excess of $40,000,000.
Roy Water Conservancy Subdistrict secondary water system was built primarily for agricultural needs in the Roy City area, as pressurized irrigation was a secondary need. Today, the primary purpose of the secondary water system is to provide pressurized irrigation for domestic lawn and garden use, as well as to conserve, develop, and stabilize supplies of water for domestic, irrigation, power, manufacturing, and other beneficial uses.
On April 30, 2007, Roy Water Conservancy Subdistrict became Roy Water Conservancy District due to a change in the Utah Code. The District’s service area is completely within Weber County and is located within the Weber Basin Water Conservancy District boundaries. The service area is primarily Roy City but has grown to include small portions of West Haven, Hooper, and Riverdale.
The District maintains over 10,000 secondary water connections for approximately 40,000 residents. The District maintains approximately 135 miles of pressurized pipe. The District services 5,528 acres of domestic lawn and garden watering along with a small portion of agriculture.
