Subject: System-Specific Minimum Sizing Standards
Syracuse City, System #06012, File #11563

Dear Robert Whiteley:

Based on the water use data submitted to the Division of Water Rights (DWRi), the following
system-specific minimum sizing standards have been set for Syracuse City water system:

Peak Day Source Demand (gal/day/ERC) – 346 gal/day/ERC
Average Annual Demand (gal/yr/ERC) – 81,938 gal/yr/ERC
Equalization Storage (gal/ERC) – 223 gal/ERC
Fire Storage (gal) – 240,000 gal

These standards are effective as of the date of this letter. A summary of the water use data and
calculations used to set the minimum sizing standards is attached for your reference. The Division
plans to evaluate these standards every 3 years, or upon request.

Water System Background

Syracuse City has a population of approximately 28,500 with an estimated 9,837 equivalent
residential connections (ERCs). Syracuse City Water System provides culinary water for indoor
and outdoor use to this population.

Minimum Sizing Standard Background

Per Utah Code 19-4-114, the information needed for the Division of Drinking Water (the
Division) to set system-specific minimum sizing standards may be based on water use data
submitted to the DWRi, or alternatively, a community water system can 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.

Actual water use data was available through DWRi and an engineering study was not submitted to
the Division for review. Therefore, the Division analyzed the submitted DWRi water use data and
sent a draft summary of the resulting system-specific minimum sizing standards to you to review
the draft system-specific minimum sizing and to verify the draft sizing standards are
representative. Therefore, the Division is setting system-specific minimum sizing standard for
Syracuse City water system.
The calculated variability for the Peak Day Demand/Equalization Storage was originally revised
as allowed by Division policy per your understanding.

Water Use Data Definitions

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 highest water consumption in a calendar year.

Average Annual Demand is 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 Storage requirement 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.

Fire Storage was set based on information from local fire district.

Storage Capacity

Based on your systems storage facilities and the storage minimum sizing requirement established
in this letter, your system is compliant with the minimum storage capacity requirements.

Source Capacity

The Division has documentation of established safe yields for all your system sources. Using total
system-wide safe yields and the source minimum sizing requirement established in this letter
indicates your water system is compliant with minimum source capacity requirements.

If you have any questions regarding this letter, please contact Nagendra Dev, of this office, at
[phone], or Michael Newberry, Engineering Manager, at [phone]. 

Sincerely,

Michael Newberry, P.E.
Engineering Manager
