Subject:Plan Approval, University Pump Station (PF004) Improvements, Salt Lake City Water System; System #18026, File #20633
Dear Teresa Gray:The Division of Drinking Water (the Division) received the plans and specifications for the proposed University Pump Station Improvements (PF004) from Elliott Bartell
of Advanced Engineering & Environmental Service LLC on April 03, 2025. Updated information about the project was provided to the Division on April 14, 2025. This project has met the
conditions for receiving a plan approval.
Our understanding of the project is that SLCPU intends to improve the University Pump Station (PF004) to replace the existing process piping and equipment to extend the life of the facility.
The pump draws water from the 32-inch diameter transmission pipeline running south-to-north directly east of the pump station and discharges into a 12-inch diameter distribution main
that runs to the east and serves customers along the north side of 500 South.
There are two existing vertical turbine pumps in the station, both of which will be replaced. The current pumps are rated for 50-hp and 150-hp and were originally installed to handle
winter and summer demands, respectively.
The new pumps (FloWise FW14HC 2-stage, 10.25-in) will be identical to one another with one serving as a standby pump for redundancy. The pumps will never run simultaneously. They will
each be rated for 100-hp and sized to meet the full demand range for the station on VFDs. The design point at full speed will be 2,000 gallons per minute (gpm) at 150 feet total dynamic
head (TDH).
The VFD currently used for the existing 50-hp pump will be upsized, while the VFD used for the existing 150-hp pump will be re-used as necessary.
We have completed our review of the plans and specifications; stamped and signed by Samuel Fankhauser, P.E., dated March 31, 2025,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 University Pump Station Improvements (PF004)Well houseare hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before the University Pump Station Improvements (PF004)put in service. A checklist
outlining the items required for operating permit 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 Nagendra Dev, P.E., of this office, at [phone], or Michael Newberry, P.E., Engineering Manager, at [phone].

Sincerely,
Michael Newberry, P.E.
