Subject:System-SpecificMinimum Sizing Standards—Final Determination
Cedar Hills Town Water System, System #25137, File #11603
Dear Kevin Anderson:
DETERMINATIONS
Based on the findings set forth below, the Division of Drinking Water (the Division) hereby establishes the following system-specific minimum sizing standards for Cedar HIlls Town Water
System(the System):
Peak Day Source Demand (gallons/day/ERC) – 675
Average Annual Demand (gallons/year/ERC) – 89,994
Equalization Storage (gallons/ERC) – 247
Fire Storage (gallons) – 1,260,000
Introduction
Pursuant to Utah Code Section 19-4-114, the Director of the Division (Director) is required to establish system-specific minimum sizing standards based on, among other factors, water
use data submitted to the Division of Water Rights (DWRi). The Director’s determinations may also be based on engineering analyses and other evidence if this is available. This final
determination letter is addressed to you in your capacity as the Administrative Contact for the System. The Director has delegated the responsibility for making system-specific minimum
sizing standards under Utah Code Section 19-4-114 to the Engineering Manager for the Division.Prior to issuing this final determination letter, the Division analyzed applicable DWRi
water use data and sent a draft summary of the Division’s proposed system-specific minimum sizing standards to the System on January 29, 2025. The Division allowed for 30 days for the
System to review the draft system-specific minimum sizing. The System’s consultant Josh Bean of Bowen and Collins provided comments on February 26, 2025. The Division has taken these
comments into account in reaching this final determination of the system-specific minimum sizing standards for the System. A summary of the water use data and calculations the Division
used to make these determinations is attached as part of the administrative record.
Water Use Data Definitions
As used in this Final Determination, the following terms have the following meanings:
Peak Day Source Demand is the total flow into a public water system to meet the demand of the water system on the day of the highest water consumption in a calendar year.
Average Annual Demandis the total quantity of drinking water flowing into a public water system within a calendar year.
Total Equivalent Residential Connections (ERCs) term represents the number of residential service connections and the number of equivalent residential connections for non-residential
connections (commercial, industrial, institutional connections).
Minimum Equalization Storagerequirement is a volume that is equivalent to the amount of water needed to meet the average day culinary demand for public water systems. Equalized storage
per ERC is calculated by dividing the Average Annual Demand per ERC data by the number of operational days in a year.
Water System Background Facts
The System is a community water system in Utah County. The system currently has 2,631 residential connections serving an approximate population of 10,035 residents. Additionally, the
System provides water to 25 commercial, and 23 institutional connections. The System operates and maintains three (3) active sources, two (2) wells and one (1) consecutive connection
to American Fork (UTAH25008), and two (2) storage tanks with the associated distribution lines.System-Specific Minimum Sizing Standards—BackgroundUnder Utah Code Section 19-4-114, the
legislature required that the Director establish minimum sizing standards on a system-specific basis instead of statewide, as the Division has done in the past. System-specific determinations
need to be based on system-specific information. The code allows the Director to rely on water use data submitted to DWRi. Alternatively, a community water system may perform and submit
an engineering study to the Division if the water system’s water use data is not representative of future use or the water system does not yet have actual water use data. In this matter,
actual water use data was available through DWRi, and an engineering study was not submitted to the Division for review. Therefore, the Division has relied upon DWRi information and
other relevant data.
Additional System-Specific Basis for Determinations
The Division established Fire Storage requirements based on information from Mat Saco and Aaron Brems of American Fork Fire & Rescue on April 30, 2020.
Storage Capacity
Based on the System’s storage facilities and the storage minimum sizing requirement established in this letter, the Director hereby determines that the System is compliant with the minimum
storage capacity requirements.
Source Capacity
The Division has adequate documentation of established safe yields (wells) for all the System’s sources. Using total system-wide safe yields and the source minimum sizing requirement
established in this letter indicates that the System is compliant with minimum source capacity requirements.
Effective Date
The determinations made in this letter are effective immediately and will become final 30 days from the date of this letter unless the System files a contest as provided below.
Notice of Right to Contest
The Director has determined this determination made under Section 19-3-114 qualifies as a “permit order” within the meaning of Utah Code Section 19-1-301.5(1)(f). See Utah Code § 19-1-301.5(1)(e)
(defining “permit” to include a “plan” or “other administrative authorization”).
The System may contest any determinations made herein by delivering a notice of contest to the Director. The notice of contest must be in writing and must be delivered to the Director
on or before 30 days after the date this letter is signed. There is no particular form for the notice of contest, but it must include the System’s reasons and rationale for the contest.
The Director’s address for purposes of submitting a notice of contest is as follows:
U.S. Mail

Division of Drinking Water
Attention: Director
P.O. Box 144830
Salt Lake City, UT 84114-4830
Email
A notice of contest may be submitted to the Director by email, provided, however, that the Director confirms receipt of the email. The Director’s email address is: [e-mail].
The email submission must be received by the Director before the expiration of the contest deadline.
If the System files a timely notice of contest, the Director will evaluate the matter and attempt to resolve the matter through negotiations. If the Director is not able to resolve the
matter, the Director will issue a final agency action regarding the contest. At that point in the process, the System shall have the right to seek further internal agency and judicial
review pursuant to Utah Admin. Code R305-7 and Utah Code Section 19-1-301.5.
Right to Request Reconsideration
The Director plans to evaluate the determinations made herein every three years. However, this requirement is not mandatory. At any time, a water system whose system-specific minimum
sizing standards have been established by the Division under Section 19-4-114 may request reconsideration of the Director’s determinations by submitting a written request. A request
for reconsideration shall be submitted to the Director in the same manner as a notice of contest provided above.
Conclusion
If the Systemmanagement has any questions regarding this letter, please contact Dani Zebelean, P.E., of this office, at [phone], or me at [phone].
