Subject:Temporary Operating Permit, Replacement of Ridgeland Booster Pump Station (PF002), Granger-Hunter Improvement District Water System, System #18007, File #13277, SRF #3F1850
Dear Jason Helm:
The Division of Drinking Water (the Division) received a request for a temporary Operating Permit for the use of the Ridgeland Booster Pump Station (PF002) from Jeremy Gregory on July
15, 2024. The Division issued Plan Approval for this booster station on March 03, 2023. This project has met all the conditions for receiving temporary operating permits. Our understanding
of the project is that Granger Hunter Improvement District (GHID) replaced the existing Ridgeland booster pump station and flow control building located at 2390 S 3600 W in West Valley
City, Utah, to feed the drinking water distribution system in the nearby area.The booster pump station and flow control building are being replaced due to the age of the existing pumps
and building.The building previously housed a now abandoned well (age is estimated at 1969).  This pump station draws water from the existing Ridgeland #5 2 MG Storage Reservoir (ST007).
The new pump station includes both the flow control valve and booster pumps and will more reliably supply water to the existing Zone 4 pressure zone. Along with replacement, the district
also replaced approximately 75 feet of the existing 14-inch diameter asbestos cement pipe with 16-inch diameter PVC C-900 pipe and site work. The site work included replacing the onsite
generator, removing the fuel station, adding two stormwater detention ponds and site landscaping to West Valley City Standards. The tank is filled with the same line that feeds the booster
pumps. It is a bi-directional fill and pump line. The flow into and out of the tank is controlled by a flow control valve. The two new horizontal split-case booster pumps are the same
capacity as the two booster pumps that they replaced. The water pressure in Zone 4 is not expected to change with this replacement project. This pump (model Peerless pump 6AE16) system
is designed to deliver 2,000 gallons per minute (gpm) from ST007 at total dynamic head (TDH) of 201 feet to Zone 4 with the capacity of 150 HP.
We have received the following information for Ridgeland Booster Pump Station (PF002):
Design engineer’s statement of conformance.
Satisfactory bacteriological results as evidence of proper disinfection and flushing.
We have determined that the conditions for issuing a Temporary Operating Permit have been sufficiently met. On this basis, a Temporary Operating Permit forReplacement of Ridgeland Booster
Pump Station (PF002)are hereby issued subject the following conditions to be completed by GHID by the end of August 31, 2024:
Evidence of O&M manual delivery
Several site asphalt repairs
Several landscape item repairs
Install Back-up generator
General site cleanup and repair building cosmetics
