Subject:Plan Approval, North Sage Estates Subdivision (DS001);
Koosharem Town, System #21010, File #13631
Dear Jeffery Jon Hatch;The Division of Drinking Water (the Division) received the plans and specifications for the proposed North Sage Estates Subdivision from your consultant, Kelly
Chappell with Ensign Engineering, on February 15, 2024. This project has met the conditions for receiving a plan approval for the installation of the proposed pipelines.
Our understanding of the project is that a new 19 lot subdivision is proposed on the northwest side of Koosharem Town. The proposed subdivision will connect into the existing drinking
water system on 650 North at two locations, approximately 50 West and 100 West. This will provide a “looped” pipeline for the proposed subdivision. Approximately 2,300 feet of 8-inch
diameter PVC pipeline, 4 fire hydrants, 1 combination air-vacuum valve, 19 service connections and 3 isolation valves will be installed. A hydraulic analysis for this subdivision was
included in the Town’s water master plan dated December 2023. The hydraulic analysis shows that the proposed pipelines will meet the 40-psi minimum pressure during peak day demand.
We have completed our review of the plans and specifications, stamped and signed by Kelly Chappell, P.E., dated April 20, 2023, 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 Sage Estates Subdivisionare hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before the new 8-inch pipeline may be put in service. A checklist outlining the items
required for operating permit issuance is enclosed for your information.Approvals or permits from the local authority or the county may be necessary before beginning construction of
this project. As the project proceeds, notice of any changes in the approved design, as well as any change affecting the quantity or quality of the delivered water, must be submitted
to the Division. We may also conduct interim and final inspections of this project. Please notify us when actual construction begins so that these inspections can be scheduled.
This approval must be renewed if construction has not begun or if substantial equipment has not been ordered within one year of the date of this letter.
If you have any questions regarding this approval, please contact John Chartier, DEQ Central District Engineer, at [phone], or me at [phone].
Sincerely,
Michael Newberry, P.E.
