When water first comes to the water treatment plant on Chestnut Street, it comes straight from the Barren River.
Mike Gardner, of Bowling Green Municipal Utilities, says: "The water is pumped up from the river with low service pumps. It comes up into the plant."
Throughout the day, workers collect water from the river to test it. That's how they determine what amount of chemicals is needed to treat it.
Gardner says: "During times when it rains and whatnot the river gets muddy and they have to go down more often, so that they can make adjustments in the chemical feed and keep the system in balance that way."
Then it goes trough a filtration system. The filters separate any sediment that is in the water. The water that is leftover after the filtration process is sent to this tank, where it is eventually sent into the sewer and back into the river.
Gardner says: "After the water goes through the filter, it flows to one of two tanks. That just provides residence time for the water to be completely disinfected. And we're sure before we pump it out into the system that there are no remaining problems with it. It's in those tanks for sometimes hours, sometimes days; depending on what the demand is."
Finally all the clean, clear water gets pumped to water towers across town. And that's where the water you use everyday comes from!
The water treatment facility treats up to 22-point-eight million gallons of water a day. Right now they're undergoing a renovation that will allow them to treat up to 30-million gallons a day.
