** 2013 Utility Rates - In 2019, a rate study increased water and sewer rates. Prior to 2019, water and sewer rates remained unchanged since 2013. This image shows the 2013 rates to 2019 rate increase.

The national average water use for a family of four is approximately 1000 cubic feet (cf)¹ each month. A home with an irrigation system can use considerably more. Apartment complexes use approximately 500 cf of water each month.

¹100cf = 750 gallons. To place these measurements in perspective:

Average bath = 50 gallons
Average shower = 20 gallons

Summer Sewer Averaging (SSA)

During the summer months, the City understands not all water consumption is going into the sewer as household waste water. The City recognizes water for gardens, landscaping, etc., goes into the ground or the drain at the street. Therefore from June 15th to September 15th of each year, sewer consumption rates are based on average winter consumption.
