Sunset City
Water Quality Report
2023
We are pleased to provide you with this year’s Annual Water Quality Report. We want to keep you informed about the excellent water and services we have delivered to you over the past
year. Our goal is and always has been, to provide you with a safe and dependable supply of drinking water. The water we drink in Sunset is purchased from the Weber Basin Water Conservancy
District
Sunset City has a Drinking Water Source Protection Plan that is available for review to our customers at our city offices. It provides more information about potential sources of contamination
and our source protection areas. Our Sources have a low level of susceptibility from potential contamination from sources such as roads and residential areas.
We are pleased to report that our water is safe and meets federal and state requirements. If you have any questions about this report or concerning your water utility, please contact
the Sunset City Public Works office at 801-979-8913. We want our valued customers to be informed about their water utility. If you would like to attend any of our regularly scheduled
City Council meetings, they are held on the 1st and 3rd Tuesday of each month, 6:30 p.m., at the Sunset City offices, 200 West 1300 North, Sunset, Utah.
Sunset City routinely monitors contaminants in our drinking water in accordance with the Federal and State laws. The following table shows the results of our monitoring for the period
of January 1st to December 31st, 2023. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some contaminants. It’s
important to remember that the presence of these contaminants does not necessarily pose a health risk.
In the following tables you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms, we’ve provided the following definitions:
Detected Contaminant – Any contaminant detected at or above its minimum detection limit (MDL).
Minimum Detection Limit – The lowest level at which a particular contaminant is detected with a specific degree of certainty.
Maximum Contaminant Level (MCL) – The “Maximum Allowed” (MCL) is the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible
using the best available treatment technology.
Maximum Contaminate Level Goal (MCLG) – The “goal” (MCLG) is the level of a contaminant in drinking water below which there is no known risk to health. MCLGs allow for a margin of safety.
Not Applicable (NA)– there is no Federal or State MCL and or MCLG
NTU – Nephelometric Turbidity Unit – a measure of the cloudiness of the water.
Non-Detects (ND) – laboratory analysis indicates that the contaminant is not present.
Parts per million (ppm) or Milligrams per liter (mg/l) – one part per million corresponds to one minute in two years, or a single penny in $10,000.
Parts per billion (ppb) or Micrograms per liter (ug/l) – one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.
Picocuries per liter (pCi/L) – Picocuries per liter is a measure of radioactivity in water.
Sunset City purchases 100% ofits water from the Weber Basin Water Conservancy District whose primary source of water comes from the Weber River Basin. The district has divided their
culinary water supply into three separate distribution systems. These systems are Weber Basin NORTH, Weber Basin CENTRAL, and Weber Basin SOUTH. A copy of Weber Basin’s Consumer Confidence
/Water Quality Report can be obtained by contacting their office on 801 771 1677 or thru their website. Weberbasin.com.
The following table represents test results of Weber Basin CENTRAL, which supplies Sunset City with culinary drinking water.

Water Quality Inside Your Home
Sunset City delivers water that is cleaner than required by state and federal law. However, once water passes from our system and through the meter, you become a partner with us in making
sure it stays that way. Here are some things to consider.
Water Heaters
Check the temperature setting for your water heater. Water that is too hot can create a burn hazard, while water that is too cool can create a perfect environment for bacteria to grow.
You may also want to consider installing a pressure regulator to prevent any sudden surges to your water heater.
Filters and Purifiers
All types of filters and purifiers need to be properly maintained and monitored. Neglected devices may not work as intended. They can become a haven for microbial growth, or shed filter
material into your home’s tap water. Even the filter in your refrigerator needs to be maintained to protect your family.
Water Softeners
Since the hardness of your water can range anywhere from 1 to 12 grains per gallon, it is important to monitor the settings on your water softener regularly to make sure that you are
treating your water properly. Over treating your water is wasted money, while under treating is not effective.
Unused Rooms
If you have a kitchen or bathroom that rarely gets used, you should make a point of running water through the faucets on a frequent basis. Stagnant pipes and fixtures are susceptible
to microbial growth. Flushing unused water lines regularly will help prevent this.
Lawn Care
Make sure you have an approved backflow device on your sprinkling system. Remember anything you hook to the drinking water to help maintain beautiful landscaping has the potential to
backflow into your drinking water. Please be careful when using chemicals that hook to a garden hose.

Drought Contingency Planning
The District worked with stakeholders in the area and the Bureau of Reclamation to prepare a Drought
Contingency Plan. The goal of this plan is to prepare for future droughts by better understanding past droughts,
improving our ability to monitor current droughts, and implementing mitigation and response actions. If you
would like additional information about this plan, please contact Ashley Nay at [phone] or
[e-mail].
The Utah State Department of Planning and Budget projects that populations in Davis and Weber County will
nearly double over the next 40 years. With a doubling population and limited future water development, the
existing water supply will not meet the projected demands. Please take some time and learn why water
conservation is important for a long-term stable water supply. There are plenty of resources available and
information on how to achieve the landscape style you want while reducing the amount of water applied to
maintain it. Thank you for your efforts in helping us continue to provide water for all our needs and varied uses.
Get Involved
The District has regularly scheduled Board of Trustee meetings. These meetings are typically held at the
District headquarters in Layton, Utah. If you would like to attend, please call for information about the meeting
schedule and location. The District is open each standard working day and welcomes public input. You may call
us at [phone], write to us at Weber Basin Water Conservancy District, 2837 East Highway 193, Layton,
Utah, 84040; or visit our web site at: www.weberbasin.com
