Subject:Plan Approval, 3-Million Gallon Storage Tank and Booster Pump Station (ST012, PF006); Farmington City Water system, System #06004, File #17927
Dear Larry Famuliner:The Division of Drinking Water (the Division) received the plans and specifications for the proposed 3-million-gallon (MG) storage tank and booster pump station
from your consultant, Jason Bradford, P.E., on November 22, 2024. The Hydraulic Analysis Certification for this project was received on December 4, 2024, signed, and stamped by Nathan
Smith, P.E. Written review comments were provided to your consultant on December 9, 2024. The Division received responses to all review comments on January 3, 2025. This project has
met the conditions for receiving a plan approval.
Our understanding of the project is the construction of a 3-MG reinforced concrete storage tank and booster pump station. These facilities will be identified as A-1 Storage (ST012) and
N-3 Booster (PF006) in the Division’s database. The new 3-MG tank will be located near the existing 2-MG Tank (C-1 Storage, ST004). Included in the valve vault building for the new tank
will be a booster pump skid with a total of three pumps (2 duty, 1 redundant), each with the capacity of 350 gallons per minute (gpm) for a total flow of 700 gpm. The booster pump will
replace the existing N-3 Booster (PF002) once the project is completed.
We have completed our review of the plans and specifications, stamped, and signed byJason Bradford, P.E., dated November 20, 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 A-1 Storage (ST012) and N-3 Booster (PF006) are hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before the storage tank and pump station 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 Julie Cobleigh, P.E., of this office, at [phone], or me at, [phone].
Sincerely,
Michael Newberry, P.E.
