EPCOR Water Services plans to install the world’s largest ultraviolet water-treatment system at its E.L. Smith Water Treatment Plant in Edmonton.

EPCOR announced last week it will implement a $10-million system that uses intense beams of UV light to efficiently inactivate viruses, bacteria and protozoa.

“EPCOR already has one of the best water-treatment processes in the world, but you need to keep improving if you want to remain the best and continue to surpass water quality regulations,” said president Allan Davies.

The plant will use the Sentinel UV Disinfection System developed by Calgon Carbon Corporation, which EPCOR says will significantly increase the ability to treat organisms like Cryptosporidium and Giardia (commonly known as beaver fever).

“We see this as the next step in the evolution of water treatment,” says Davies. “UV technology can be added to almost any existing treatment plant and can provide anywhere from 100 to 1,000 times the current safety factor for certain pathogens in a very cost-effective manner.”

Edmonton-based EPCOR has operations throughout Alberta, British Columbia, Manitoba, Ontario and the U.S. Pacific Northwest.
