Construction at Treatment Plant

Alderwood Water and Wastewater announced plans to begin preliminary work at the Picnic Point Treatment Plant.  The work will start around February 22, 2021 with some drilling and  preliminary soil testing in preparation for the construction of an Equalization Basin.  The Equalization Basin is expected to be located at the uphill end of the existing plant.

Actual construction is planned to begin in late spring of 2022, and is anticipated to last for about 18 months.  Initial design plans are for the buildings to closely match the design of the existing treatment plant.

If you have any questions, you can email the district directly at, or call Josiah Hartom at 425-741-7969.  There will also be monthly updates on the website:  https//
