   Water Division 11.2018

The City of Redmond’s Water Division provides clean drinking water to customers and promotes water conservation. 


Drinking Water Source

The City’s drinking water comes from groundwater. The City has several wells that pump groundwater from a large geologic formation called the Deschutes Formation, which is made up of layers of volcanic rock and porous sediments. Groundwater in the Deschutes Formation is replenished by melting snow and rain that falls over the Cascade Mountains.

Water Infrastructure

The City’s drinking water system relies on 7 wells that produce water year-round. The City also has 6 reservoirs with the combined capacity to store 13.5 million gallons of water. These reservoirs allow the City to meet peak demands and fire protection needs. The system reservoir is elevated to maintain water pressure in the main portion of town. Water pressure is supplied by gravity and booster pump stations that increase water pressure where needed. The City has a total of three service zones, five booster pump stations, and 163 miles of pipeline.

Water Use

The City’s water customers use approximately 2.3 billion gallons of water a year. Redmond’s average daily water demand is 2.4 million gallons per day in the winter (December through March), but jumps to 13 million gallons per day in July and August.

There are four categories of water users in Redmond: single-family residential, multifamily residential, commercial, and city uses (this category includes City facilities, parks, the wastewater treatment plant, and potable water system maintenance). The majority of the City’s water use is residential (single-family and multifamily), and a large portion of residential use is for outdoor watering. The percentage breakdown of typical annual water consumption by customer category is: 59% single-family residential, 27% commercial, 9% multi-family, and 5% city.

Water Conservation

Water conservation is a priority for the Water Division. Water conservation not only reduces the City’s demands on precious water resources, it can reduce demand enough to delay infrastructure expansion projects.

The Water Division is carrying out the following activities to promote water conservation and wise water management:

  • Outreach and Education:
    • The City provides water conservation tips and resources to customers through City newsletter articles, brochures, billing messages, and its website.
    • The City offers a Do-It-Yourself Water Assessment to help customers find and fix leaks, as well as identify opportunities to improve indoor and outdoor water efficiency. 
    • The City hosts a water conservation booth at community events to teach residents about groundwater, the City’s water supply, and water conservation.
    • The City teaches elementary students about their water supply and water conservation.
  • AquaHawk
    • The City provides AquaHawk, a free water monitoring service that allows customers to receive leak alerts and access their water usage information online. Learn more about AquaHawk here.
  • Annual Water Audits
    • Every year, the City compares the amount of water produced to the amount of water consumed to assess whether we may be losing water to leaks in water distribution lines or unauthorized uses.
    • The City has a leak detection and repair program to identify and fix leaks in water distribution lines.
  • Up-to-Date Water System Metering
    • The City has automatic meter infrastructure (AMI) for customer water meters. AMI allows the City to identify meter malfunctions and to promptly notify customers of a suspected leak.
  • Water Efficiency Resources
    • The City provides free water-saving devices (shower heads, faucet aerators, and shower timers) to customers.
    • The City has rebate programs to promote efficient water use indoors and outdoors.
