Blue Heron Water Reservoir

Crews with Stellar J Corp. began construction of the first of two new water reservoir tanks to replace the existing 40-year-old, 3-million-gallon tank at Blue Heron Circle in July 2017.

The project consisted of building one 1.5-million-gallon tank west of the existing tank, demolishing the original reservoir then building a second 1.5-million-gallon tank on its foundation site.

The entire project was completed in 2018.

The two new tanks were painted a slate gray identical to the reservoir at the Water Treatment Plant alongside the Skagit River in Mount Vernon.

The tank was filled with water remotely from the Water Treatment Plant in late February. It took 7 hours at a rate of 4,000 gallons per minute. Water quality testing was done and the tank put into operation mid-March.

Demolition of the old 3-million-gallon tank started soon after. The second new 1.5-million-gallon reservoir was constructed on its footprint.

The second of two 1.5-million-gallon reservoirs at the Blue Heron pump site was almost complete with the sides, roof and some of the accessories such as ladders attached. Next came coating the tank and painting it and the companion tank right next to it.

The construction of the two brand new 1.5-million-gallon water reservoirs off Blue Heron Circle was completed in 2018. The tanks replaced the 40-year-old, 3-million-gallon tank that was showing signs of structural degradation. Having two tanks will provide a backup for the city in the case of an emergency and during routine maintenance. The project was completed by Stellar J Corp. or Woodland for approximately $5 million, paid for with a loan from the U.S. Environmental Protection Agency Drinking Water State Revolving Fund.
