Leaks are common on old systems.  As pipe, fittings, and other distribution components age and corrode, leaks begin to form.  Unless the leak is large and exits the ground, Operators have no way of knowing that a leak exists without doing water audits and/or using specialized equipment to listen for the leak.  The majority of leaks are small and lose a small amount of water over a very long period of time.  The water dissipates into the ground and is never seen.  Much of the District's infrastructure was installed in the 50's and 60's.  For this reason, the District is currently investing a lot of money into replacing large portions of the culinary distribution system each year.


The District's annual per capita culinary water use is currently 55 gallons per day.  During the irrigation season, the per capita water use per day for irrigation water is 238 gallons.  






The State's total per capita water consumption in 2010 was 240.  This amount includes institutional, commercial, and industrial supply, as well as outside irrigation.  The District's indoor water use of 55 gpcd is very comparable to the State's 2010 indoor water use of 60 gpcd.  It is the District's outdoor water use of 238 gpcd that is in stark contrast to the States's average of 105 gpcd.  The District uses 133 gallons more per capita per day than the rest of the State.


The reason for this is simple; the District's outdoor water use is not metered, whereas much of the State does not have unmetered irrigation water.  The District is not the only entity that has unmetered irrigation, of course.  All of these areas show the same high per capita outdoor use.  Some of these areas are starting to install secondary water meters in order to slow down this high consumption.  

Utah is one of the three fastest growing states in the nation.  According to the Governor's Office of Management and Budget, Utah's population is projected to grow to 6 million by 2060.  By the year 2060, Utah's population is expected to double.  


For this reason, the Utah Legislature signed off on two billion dollar projects that would convey billions of gallons of water many miles to locations that are in need.  Two such projects are the Bear River Development project and the Lake Powell Pipeline project.    


The Lake Powell Pipeline project entails running a 139-mile pipeline from Lake Powell to Kane and Washington counties.


The Bear River Development project consists of building two new dams along the Bear River, as well as raising the height of the existing Hyrum and Willard Reservoirs.


The South Davis Water District can help this conservation effort by reducing it's per capita irrigation water consumption.  Not only will it benefit future generations for us to conserve our irrigation water, but it will help ensure that we can continue watering with unmetered irrigation water.




The South Davis Water District is committed to water conservation.  The statewide water conservation goal for Utah is to reduce per capita Municipal and Industrial (M&I) water use by 25% by 2025.  Accomplishing this goal would translate into water savings of 163 billion gallons per year.  Conserving the water we have now is by far cheaper than constructing new reservoirs or accessing new sources of water.


The District serves a population of roughly 9,891 people, and has combined equivalent culinary and irrigation connections totaling 5,134.  The following chart shows the amount of both culinary and irrigation water that the District has provided to residents since 2005. 




Culinary water production has been decreasing gradually as the District has been reducing the number of leaks in the system by repairing or replacing old infrastructure.  It is estimated that the District loses approximately 49 million gallons of culinary water per year through leaks and hydrant flushing.  


The need for hydrant flushing is a function of insufficient flow or demand in a particular area of the system causing stagnation.  Operators must flush these areas in order to maintain fresh water, causing significant water loss.  Insufficient flow or demand is caused by incorrectly sized pipe, lack of pressure reducing valves, or improperly designed line configurations. The District is in the process of correcting these problems.



The chart to the left shows the District's use from 1968 to 2017.  The regression line shows that the District has been reducing the amount of irrigation water that it uses. 


Part of this is due to the fact that watering times were restricted.  When irrigation water was first introduced, there was no restricted watering time between 10:00 a.m. and 6:00 p.m.

Irrigation meters were never something that worked in the past because it is dirty water, but recent innovations have made it feasible to meter irrigation water.

It costs roughly $1,800 per installed meter.





Culinary water is billed bi-monthly. The amount billed is based on actual usage as read from a water meter. During the winter season, when meters are covered with snow, usage will be estimated. Failure to pay the culinary bill for 4 consecutive months will result in water being shut off.  A warning letter will be sent to the delinquent resident prior to it being shut off. 


Irrigation water is billed according to the size of the property as recorded by the County.  Residential accounts have money levied automatically through property taxes at the end of the year for their irrigation payments.  Some accounts such as commercial, HOA, government, and institutional  are still sent bills in the mail for irrigation charges.

There is no watering between 10:00 a.m. and 6:00 p.m. If found watering during off hours, a warning will be issued for a first time offender. The next subsequent violation will result in a $30 fine. Each subsequent violation will increase by $30 per violation for the entire irrigation season. The violation will be added to the residents account. Failure to pay the violation will result in a tax lien being placed on the property with an additional $30 processing fee.
Typically the irrigation season begins on the Monday closest to April 15th, and ends on the Monday closest to October 15th.  This is subject to change, however.  Certain situations can lead the District to change these dates.  We will notify you when these changes take place.
It is important to have your master valve shut off prior to the turn on date in April in order to prevent flooding.
The Board of Trustees meet on the second Wednesday of every month at 4:30 p.m. at the District Office located at 407 W 3100 S.  Public input is always welcome.
