Subject:Plan Approval, Maple Street Booster Station (PF003) and Water Line Improvement Project; Hildale - Colorado City, System #27006, File #16475, SRF #3S2669
Dear Jerold Postema:The Division of Drinking Water (the Division) received the plans and specifications for the Maple Street Booster Station (PF003) and Water Line Improvement Project
from Riley Vane, Jonesand DeMille Engineering on September 4, 2024. Written review comments were provided to you and your consultant on October 10, 2024, while funding was still being
finalized. The Division received the revised plans and specifications on November 6, 2024. Follow up review comments were sent to you and your consultant on November 19, 2024. A comment
response and revisions were received by the Division on November 20, 2024. This project has met the conditions for receiving a plan approval.
Our understanding of the project is to add water lines to the upper part of the Heights Subdivision. To be able to provide adequate pressure, a booster station also has to be constructed
that will provide maximum flow to this area as well as fire flow.
The water line construction includes 1,980 linear feet of 8-inch diameter PVC C900, 220 linear feet of 10-inch diameter PVC C900, and 2,410 linear feet of 12-inch diameter PVC C900 pipe.
All appurtenant valves and fittings are part of the project.
The Maple Street Booster Station will include a new booster pump station building that will house a Grundfos CR15-3 pump skid (or equivalent). Initially this will include three 7.5 horsepower
centrifugal pumps that can each pump 125 gallons per minute (gpm). Two pumps will be
operational, allowing for a combined capacity of 250 gpm. Space for a future fourth pump has been designed into the project. There will also be a large capacity 60 horsepower centrifugal
pump that can deliver 1,200 gpm in the event of a fire flow scenario. The Maple Street Booster Station will be referred to as PF003 in the Division’s inventory.
We have completed our review of the plans and specifications, stamped, and signed byRiley Vane, P.E., dated November 6, 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 Maple Street Booster Station (PF003) and Water Line Improvement Project are
hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before the Maple Street Booster Station (PF003) and Water Lines 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.SRF FundingThe project, as described
herein, is generally eligible for assistance under the Drinking Water Construction Assistance Program. All change orders will need to be reviewed and approved for compliance with the
Drinking Water Rules and the conditions of this construction approval.The project may now be advertised for bids. But, as a condition of the project funding, you must not award the contract
or proceed with construction until the Division of Drinking Water has authorized you to do so. This is necessary to comply with applicable requirements and to protect you, as the funding
recipient, by ensuring that the contract meets requirements for funded projects.
If you have any questions regarding this approval, please contact J. Paul Wright, P.E., DEQ Southwest District Office, at [phone], or me at (385) 515‑1464.
Sincerely,
Michael Newberry, P.E.
