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 first tank was scheduled to be complete and in service in March 2018.
After the underground piping and tank floor were completed in November 2017, welding of the steel sides began.
In December 2017, crews were welding the roof plates, using a center column support.
By the end of the year, the entire roof was in place.
In January 2018, crews finished coating the inside of the tank with a protective material..
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.
Demolition of the old 3-million-gallon tank started soon after. The second new 1.5-million-gallon reservoir will be constructed on its footprint.
Construction of the second of two 1.5-million-gallon water tanks began in April at the Blue Heron reservoir and pump station.
