RE: Request Operating Permit for Kolob Heights Well (WS001), Well House, Transmission
Line, and Tank – System #11831, File #12585, 12586, and 13095
Dear Paul,
The Kolob Heights Well (WS001), well house, transmission waterline, and Tank were constructed
according to the approved plans and specifications and any changes made were done in
accordance with Utah Drinking Water Rules as described in the Utah Administrative Code, Rule
Series 500.
Changes that are noted include adjustments to the booster pump setup and sizing. These
adjustments were done primarily due to permanent power source available. A booster pump skid
sized and tested to maintain 98 gallons per minute at 60 pounds per square inch pressure was
installed to maintain average and peak day flow demands. In coordination with WCWCD a third
pump is going to be added to the system to provide another 49 gpm to the system to supplement
peak times. The fire pump was placed on a variable frequency drive and set points to provide
water during peak times when the smaller jockey pumps are unavailable to provide sufficient flow
and pressure and for when a fire demand is required. Coordination was done with the local fire
authority and fire chief to agree the use of the fire pump as a backup booster pump. A letter from
Fire Chief Jim Banks from the New Harmony Fire Department is attached approving the use of
the fire pump.
During the plan approval period, waterlines were added but have not been design for the Jim
Carter Subdivision that sits south of the highway and be connected to the system. Nothing has
been constructed outside of Kolob Heights and plans will need to be reviewed and approved prior
to adding these connections to the system.
