Subject:Plan Approval, Sky Ranch Area 2 MG Tank (ST009), Transmission Line and Sky Ranch Area Pump Station (PF011); Hurricane City, System #27007, File #18884
Dear Ken Richins:The Division of Drinking Water (the Division) received the plans and specifications for the Sky Ranch Area 2 MG Tank and Transmission Line Project from Glen Carnahan,
P.E., Alpha Engineering, on January 13, 2025. J. Paul Wright, Department of Environmental Quality (DEQ) Southwest District Engineer, met with Glen Carnahan on January 22, 2025. During
that meeting the overall project was reviewed, including the pressurized irrigation portion of the project, and how it may relate to any drinking water interferences. It was also explained,
during that meeting, that the drinking water portion of the project includes a booster station that will be used for the time being to convey water to the new 2-million-gallon tank.
Revised plans, including the pump station, were received by the Division on January 30, 2025. Plan review comments were provided to you and your consultant on February 26, 2025. Final
plans for construction were received by the Division on March 5, 2025. This project has met the conditions for receiving a plan approval.
The project, as we understand it, includes the following components:
Sky Ranch Area 2MG Tank (ST009)
This facility includes a 2 MG reinforced concrete tank (identified as ST009 in the Division’s inventory database) with all associated appurtenances, hatch, air vent, and overflow/drain
line. The tank also includes the installation of approximately 1,180 linear feet of 18-inch ductile iron pipe to be used as inlet and outlet water lines for the tank that will connect
to the new transmission line described below.
Sky Ranch Area Tank Transmission Line
This transmission line will connect to the existing Hurricane City distribution system. The transmission line includes 3,370 linear feet of 18-inch ductile iron pipe and will convey
water to the new Sky Ranch Area 2MG Tank (ST009).
Sky Ranch Area Tank Pump Station (PF011)
This pump station is being installed to be able to deliver water from the existing distribution system to the new Sky Ranch Area 2MG tank (ST009). This will be needed until the proposed
Sky Ranch Well is in operation. The pump station will be a submersible pump, in a pump can, similar to a submersible well and will be sealed, similar to a well head. It will be located
in a vault that will have a sump pump to protect it from flooding. The submersible pump will be 40 hp and have the capacity to pump 800 gallons per minute. All other controls will be
installed at the pump station site.
Pressurized Irrigation System
The Division of Water Resources funding for this entire project includes Phase 2 of a pressurized irrigation system including distribution piping and irrigation reservoirs. This has
been an ongoing project in Hurricane to provide pressurized irrigation to more customers throughout the city. While the Division of Drinking Water has no oversight authority nor regulations
to review the pressurized irrigation system, the project was reviewed to ensure that no interconnections nor cross connections were included in the project. After this review with the
project engineer, it appears that the two systems (drinking water and pressurized irrigation) are completely separate from each other.
We have completed our review of the plans and specifications, stamped and signed byGlen E. Carnahan, P.E., dated January 27, 2025, and found 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 Sky Ranch Area 2 MG Tank (ST009), Transmission Line and Sky Ranch
Area Pump Station (PF011) are hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before these facilities 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 J. Paul Wright, P.E., DEQ Southwest District Office, at [phone], or me at [phone].
Sincerely,
Michael Newberry, P.E.
