DUVALL, Wash. — The City of Duvall's treatment plant has reached its limit amid continuous heavy rain.

"It has just been flooding like crazy," said Bobby Twedt, a Duvall resident.

So much so, the city posted a video Thursday asking residents to reduce the amount of water they use until the heavy rain that has caused flooding throughout the region subsides.

"With all this rain, our treatment plant has maxed out," explained city spokesman Shaun Tozer in the video. 

The plant went from treating 500,000-700,000 gallons of water a day to at least 2 million gallons, according to Tozer. Crews worked overnight to ensure processing continued.

"This is going to be our fifth major flood of the season," said Tozer.

Residents are asked to limit showers and laundry, as well as reduce the number of toilet flushes.

“They’re trying to be cute about it, but at the same time they’re serious. The plant cannot handle any more water,” said Teri Deselle, who works in downtown Duvall.
