Artesian Well

Artesian Well Information

CURRENT INFORMATION: One Night Site Closure of 164th Street Artesian Well

In order to upgrade and improve fire protection, and to replace a damaged water hydrant, the artesian well site on 164th St SW., Lynnwood, WA, will be temporarily closed on Thursday, November 16, 2023, from approximately 9 PM until Friday, November 17 at 6 AM.

This site closure will allow Alderwood Water & Wastewater District (aka AWWD) to complete water main work. While this type of work typically lasts 4-6 hours and should not last for more than 10 hours, although the actual duration of the work will depend on the conditions encountered.

No public access to the site will be allowed for the safety of staff and the public. The public is also advised to please keep the gravel parking area clear of parked cars during this time. Thank you in advance for your patience and understanding, and we apologize for any temporary inconvenience this closure may cause.

Any further work-specific questions or concerns may be directed to AWWD’s Water Systems Operator Matt Nugent at (425) 787-0250 or


“The well,” also known as Well No. 5 or the 164th Street Artesian Well is in excess of 400 feet in depth and is cased to approximately 120 feet. The well flows at a rate of about 10 gallons per minute. 

The source of water at the well is an underground aquifer (water-bearing layer of permeable rock, sand or gravel). The well taps the Intercity Aquifer at approximately 200 feet.

As a courtesy to residents, Alderwood Water & Wastewater District maintains this flowing artesian well as a community source of water for those who prefer untreated water.

Please help us keep the well site clean!
Carry out what you bring in.
