Water firm installs ultraviolet disinfection at Granite City treatment plant

Investment of about $6 million supports safe drinking water

Illinois American Water recently invested approximately $6 million to construct ultraviolet disinfection at the Granite City water treatment plant.

The new treatment technology supports safe drinking water to residents and businesses.  As part of the project, three new UV reactors were installed and are capable of treating up to 15 million gallons of water a day.

According to Brent O’Neill, director of Engineering for Illinois American Water, UV technology is effective in inhibiting infection-causing microorganisms and adds another layer of protection for customers.   When used to treat drinking water, UV disinfection addresses chlorine-resistant pathogens and microorganisms that could be present in surface water sources. The Granite City water treatment facility uses the Mississippi River as its water source.

“There is nothing more important than the quality of the product we deliver to our customers’ taps,” O’Neill said. “This is why we continuously work to upgrade technology and treatment processes to deliver safe drinking water. We are excited to incorporate UV disinfection to our treatment process for particular water sources.”

The investment will also help meet more stringent water quality regulations associated with the Environmental Protection Agency’s Long Term 2 Enhanced Surface Water Treatment Rule.

According to O’Neill, Illinois American Water not only meets EPA drinking water guidelines, but the company “provides water quality which is better than required.”

He added, “Our customers trust us with a critical service.  They serve our product to their family, their children.  We take our responsibility seriously and are proud to deliver quality drinking water to the Metro East area for over 130 years.”
