Drinking Water

PFAS Information

The City of Redmond’s drinking water remains safe and protected from contaminants, including the group of human-made chemicals labeled PFAS (per-and polyfluoroalkyl substances). PFAS are manufactured for a variety of industrial purposes. If detected in drinking water, PFAS have the potential to raise health concerns. For more information about PFAS, including the health and safety risks associated with these compounds, visit the Environmental Protection Agency and Washington State Department of Health websites.

PFAS are a group of human-made chemicals that have the potential to adversely affect human health and the environment. PFAS have been manufactured and used in the US and around the world since the 1950s in food packaging, non-stick cookware, and firefighting foam.

Drinking Water Quality

Redmond is part of the Cascade Water Alliance (CWA) and buys 60% of its supply from the Seattle Tolt River supply through the CWA. TheGlassWater rest of our drinking water supply comes from our five municipal supply wells that serve the areas of town east of the Sammamish River. The City of Redmond believes that safe drinking water is no accident - it is our highest priority - but we need your help to continue to be successful.

Redmond’s Wellhead Protection Ordinance was a major step toward protecting the approximately 40% of our City’s drinking water supply that comes from groundwater. Learn more about Redmond’s groundwater and wellhead protection program here. 

Redmond’s drinking water meets or exceeds all Environmental Protection Agency and Washington State Department of Health drinking water regulations. Water from each supply well is treated before it enters the City water supply system. Currently, Redmond provides three types of treatments - fluoridation, chlorination, and pH adjustment - to comply with these regulations.

Lead service line inventory

On January 15, 2021, the U.S. Environmental Protection Agency (EPA) issued Lead and Copper Rule Revisions (LCRR) that went into effect on December 16, 2021. This rule requires jurisdictions to collect and submit service line inventories to the Department of Health. The City of Redmond Water Quality Division is required to follow this updated rule. This effort is to minimize potential health risks to the community. 

Lead has many harmful health impacts, including-

  • Brain and kidney damage

Children with lead exposure are more likely to have-

  • Central and peripheral nervous system damage
  • Impaired formation, including learning disabilities and shorter stature
  •  Blood cell damage

In some older homes, lead may be present in the pipe connecting the house to the water system – known as a service line – or in the home plumbing. Lead in service pipes or plumbing can dissolve or break off into water and end up at the tap.

For additional information, contact LSL@redmond.gov.

The City is committed to providing customers with abundant, safe, clean, and reliable drinking water. Thanks to the dedication of city staff, Redmond’s drinking water continues to exceed the highest drinking water standards in Washington State.

Meters & Leaks

Our Water System Operations staff install and read water meters, locate and repair leaks in the City’s system, anWaterMeterd maintain other system components.

We can assist in locating your water meter, reading your meter, water shut-off for emergencies, diagnosing pressure problems, and advise for tracking down system leaks. Property owners are responsible for the maintenance and repair of the service line from the meter to the home or business.

Our water meter readers work throughout our neighborhoods and business districts. They read residential meters (bi-monthly) and commercial meters (monthly), then send this information to Utility Billing for processing. The readers also install and repair meters do final reads for billing, shut-offs, meter turn-on, and other service orders.

Water Meter Accessibility 

Our staff reads your meter either monthly or bi-monthly, depending on your account type. Please keep your meter accessible so our staff can quickly read your meter on the first visit to your property. If your meter is obstructed, a meter reader must return to your property to clear the obstruction and read your meter. A charge to your account will occur for this return visit.  By keeping your meter box clear, you can avoid this charge. Additionally, a clear box makes it easy to ensure that the lid fits properly, is safe, and that the meter can be quickly turned off in an emergency. Water Meter Box

Trees, bushes, and plantings

  • Trim bushes, trees, and grass that block the way or cover the meter. During the growing season, plants can quickly cover a water meter box.
  • If you add bark or gravel in your landscaping, please take time to remove any debris covering the meter box.
  • Please minimize plants where meter readers must travel to get to your meter. We want to avoid any accidental damage to your prized plantings.

Objects that cover or block your meter

  • Please ensure no objects cover or block access to the meter box. Some examples we have encountered include cars, trailers, garbage cans, recycling bins, construction equipment or supplies, landscape bark, or gravel.
  • Please do not construct structures such as sheds, mailboxes or fences over your meter box. If the meter box cannot be quickly accessed in an emergency, utility personnel will have to remove the structure. 

Your address

  • Please ensure your house address is clearly displayed on your residence.
  • This also assists emergency personnel who may need to find your home quickly.

Pets

  • Keep pets away from the path that leads to your meter.
  • If you have a guard dog for security, please let us know so that we can make sure that our meter readers and other utility personnel are aware of this.

Help Conserve Water

After an unusually dry summer, Redmond, in partnership with Seattle Public Utility and Cascade Water Alliance, will work together to save and stretch our water supply. Sixty percent of Redmond’s drinking water comes from the Tolt River Reservoir, and until we get enough fall rain to keep people and fish healthy, we should all do what we can to save. The City of Redmond will reduce the water we use for city operations by draining decorative fountains and moving early to our winter watering schedule.

Steps to reduce water use
  1. Is water usage reduction mandatory?
  2. Why are we trying to reduce water usage when it is raining outside?
  3. Why are the City of Redmond, Seattle Public Utilities, and Cascade Water Alliance (CWA) all activating their water shortage response plans together?
  4. How can I reduce water usage in my home, yard, or workplace?
