New Mville water treatment plant behind schedule

MARYSVILLE Contractors have fallen behind schedule for completing the citys $3.2 million water treatment plant located next to the Arlington airport.
Representatives from the Marysville Public Works Department are having complicated discussions with contractors DMJM Harris, who are putting the finishing touches on the plant, which uses a new technology to purify water for the city customers in the northern end of town. Those conversations concern whether everything is in place and functioning correctly in the new plant. The plant is largely complete but technicians are working out the kinks and began testing just in time for this weeks record floods. Because of the flood the citys wastewater treatment plant is at capacity and city engineers had to postpone testing of the plant until dryer weather gives the sewer plant a break. Water tested at the plant is disposed of in city sewers, hence the reason for the stoppage.
We basically have to cease testing for that reason, said Pat Gruenhagen of the public works department.
Water for the new drinking water plant is fed from a well beneath the Stillaguamish River north of the city of Arlington. Piped several miles south to the plant, water is filtered with a Xeon process with dual redundant systems. The process is a new but proven technology and the city of Duvall has a couple plants using the same set up.
Yes, the project wasnt completed as quickly as we would have liked, said Gruenhagen. Its a big and complex facility and this is pretty standard.
The filtration plant cant pump water into the city pipe grid until the county health department confirms that it is up to spec and the city is working to that end. Gruenhagen said the plant should be online sometime in the next several months. Alex Kwok of DMJM Harriis would not discuss the project and referred calls to the city.
Its a big project with the fine tuning making everything right, said Marysville Mayor Dennis Kendall, adding that the delay would not impact the citys many water customers. Weve got plenty of room.
As emergencies were declared in 18 counties in Washington state the city was making every effort to keep floodwaters at bay. Two street sweepers were kept busy during the day to keep leaves and other detritus out of drains and crews were out checking drains and storm water basins. The public works department met early in the day to work on a punch list of items, according to surface water technician Kari Chennault, who said staff are keeping an eye on high tides and river cresting data.
Theyre definitely doing things differently today, Chennault said. Weve definitely today tried to be on the lookout.
