Dear Shane Owens:The Division of Drinking Water (the Division) received the plans and specifications for the North Center Street Water Line Replacement project from your consultant,
Derek Anderson, P.E. with Sunrise Engineering, on January 14, 2025. This project has met the conditions for receiving a plan approval.
On January 23, 2025, the Division received a completed Water/Sewer Separation - Exception Request Form and Water/Sewer Separation - Exception Request Spreadsheetfor an exception to Rule
R309-550-7(1), Separation of Water Mains and Transmission Lines from Sewers and Other Pollution Sources for Utah26008 Distribution System (DS001). This rule states specifically that
the horizontal distance between pressure water mains and sanitary sewer lines shall be at least ten feet and that where a main and a sewer line must cross, the water main shall be at
least 18 inches above the sewer line.
Plan Approval
Our understanding of the project includes replacing approximately 3,745 linear feet of existing 8-inch water line to include the installation of 3,500 linear feet of 10-inch diameter
PVC C900 DR-18 and 245 linear feet of 8-inch diameter PVC C900 DR-18 along North Center Street from 600 North to Main Street and along Alfalfa Circle. The work includes replacing existing
service connections and associated appurtenances.
We have completed our review of the plans and specifications, stamped and signed byJohn Keyser, P.E., dated December 2, 2024, and find they basically comply with the applicable portions
of Utah’s Administrative Rules for Public Drinking Water Systems in R309. On this basis, the plans for the North Center Street Water Line Replacement project are hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before the water lines may be put in service. A checklist outlining the items required
