Subject:System-SpecificMinimum Sizing Standards—Final Determination
Snake Creek Mutual Water, System #26011, File #12820
Dear Jacob 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 Snake Creek Mutual
Water(the System):
Peak Day Source Demand (gallons/day/ERC) – 581
Average Annual Demand (gallons/year/ERC) – 155,400
Equalization Storage (gallons/ERC) – 425
Fire Storage (gallons) – 60,000
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.The System entered into a Corrective Action Agreement on December 12, 2021, in order to
gather three years of data and report to DWRi. 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 May 28, 2025. 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 Transient Non-Community System located in Wasatch County. The System currently has 56 residential connections serving an approximate transient population of 100 people
with one (1) institutional connection. The System operates and maintains two (2) active springs and one (1) storage tank 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 the Division’s rule R309-510-9 which states “If direction from the local fire authority code official is not available, the
water system shall use Appendix B of the International Fire Code, 2015 edition, for guidance. Unless otherwise approved by the local fire code official, the fire flow and fire duration
shall not be less than 1,000 gallons per minute for 60 minutes.”.
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.
The issuance of this letter resolves your water system’s deficiencyVF34 will be added to the System’s IPS report due to a lack of storage capacity to cover the fire flow requirement.
An updated IPS report is available at https://waterlink.utah.gov. Please contact Jennifer Yee at [phone] or [e-mail] for questions related to your water system’s IPS report
or deficiencies.
Source Capacity
The Division has adequate documentation of established yields (springs) for all the System’s sources. Using total system-wide yields and the source minimum sizing requirement established
in this letter indicates that the System is compliant with minimum source capacity requirements.The issuance of this letter resolves your water system’s deficiency S094 related to lacking
greaterthan 20% of the required source capacity. The issuance of this letter also resolves the temporary exception in place for the S094 deficiency. An updated IPS report is available
athttps://waterlink.utah.gov. Please contact Jennifer Yee at [phone] or [e-mail] forquestions related to your water system’s IPS report or deficiencies.
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].
