PRWID's $5 million work at water plant about done
It took about two years and $5 million, but the benefits are clear.
You could say they're as clear as tap water, because that's what the Price River Water Improvement District puts out by the megagallons at its upgraded Castle Gate treatment plant.
PRWID has increased its production capacity by about 50 percent, going from 4 million gallons per day to 6 million.
The district has also begun injecting ozone into the raw water. Ozone is an unstable oxygen molecule with three atoms instead two. When ozone decays, the extra oxygen atom it releases attacks anything in its path.
Plant manager Ken Snook told visiting board members that the ozonation has three advantages.
First, it reduces the amount of potentially harmful byproducts produced with chlorine reacts with organic materials like bacteria and algae.
Ozone also removes odors and improves taste.
