Sprinkler watering grassWater Allotments For The 2023 Irrigation Season

Water allotments are back to normal for the 2023 irrigation season.

Irrigation Water Rates

The City adopted irrigation water rates effective July 1, 2015. The rates are tied to the water meters that were installed prior to the adoption of these rates. The purpose of the rates and meters are to encourage residents to conserve one of Utah's most valuable resources, water. 

A base rate is charged year round to cover some of the City's fixed costs in the water department. This will result in a significantly lower water bill during the non-irrigation months. Additional rates will be charged during the irrigation season based upon water usage. Each lot is assigned an allotment of water. This allotment is based upon how much water was purchased for that lot at development. The rates increase higher as residents use more or even exceed the allotment for their lot. Residents can use the irrigation calendar or the chart below to see their allotment and how much water will cost to stay within their allotment or to use beyond their allotment.

City Irrigation Calculator

The City has created an irrigation calculator to help customers determine their monthly irrigation water allotment and estimate the cost of their bill. Click the link to the irrigation calculator, which is a google spreadsheet and then you can make a copy when the page appears. You will need a Google account to access the spreadsheet. You'll be able to enter your lot size to determine your monthly water allotment. You can also estimate what your bill would be at different water usage amounts.

Water Allotment

The allotments are calculated as follows:

  • Single Family Residential monthly allotment (in thousand gallons): Gross lot acreage multiplied by 108.793732.
  • Non-single Family Residential monthly allotment (in thousand gallons): Irrigable lot area multiplied by 152.99127.

For example, a 1/4 acre lot would have an allotment of 27.2 thousand gallons (0.25 multiplied 108.793732).


The following rates do not reflect the 2022 Water Shortage Reduction. To see the 20% reduction rates go to the Water Shortage Response Plan Page

Single Family Residential Base Fee: $16.25 per quarter acre (reduced from $26.18 per quarter acre).

Non-single Family Residential Base Fee: $65 per irrigable acre. This fee includes commercial, industrial, institutional, condominiums, city parks, HOA parks, or any other non-single family property that the City has a record of the irrigable acreage of the property.
