Water treatment plant coming together

Water treatment plant coming together

Parshall’s city engineer appeared before the city council during its Feb. 3 meeting to provide an update on the progress of the Regional Water Treatment Facility.
Cory Chorney first showed a 3-Dimensional presentation of what the facility is expected to look like inside and out. He also took city council members to the site and gave them a tour of the construction site.
“This should give you a better idea of what you’re going to end up with,” Chorney said. “This is a virtual walk through.”
The $16 million plant will have two raw water pumps, each with a 3-million gallon per day capacity, according to Chorney. There are vertical turbine pumps that will bring the water through a short pipeline from the river to the plant.
Water will be filtered at least three times as it enters the plant for processing, with a fourth filter on standby, Chorney said. The filtration is the industry standard, he said, and the filters will eliminate any solid particles such as unwanted minerals from remaining in the drinking water.
Over time, the membranes that bring the water into the plant, do need maintenance and when that happens, chlorine and citric acid will be used to clean the membranes and keep them flowing properly.
When asked about citric acid, Chorney said, “yes, we’re using orange juice to clean out the pumps, but I wouldn’t drink it.”
He was referring to the environmentally friendly acid that is drawn from oranges. It is packaged in a concentrated form and works very well for this type of cleaning, Chorney said.
