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 consists 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 is scheduled to be completed in October 2018.

The two new tanks will be 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.
