Tempe first to eliminate gaseous chlorine from water treatment process

The City of Tempe's Water Utilities Department announces the removal of gaseous chlorine from its water treatment plants. Gaseous chlorine, typically stored in 1-ton cylinders, was used in the plants' water treatment disinfection processes. Gaseous chlorine is being replaced with a process that no longer uses potentially hazardous chemicals.

"We are pleased to be the first city in Arizona to announce the removal of gaseous chlorine from our water treatment plants," said Tom Gallier, water utilities manager. "By removing these cylinders, we're setting a new standard for safety. We've increased the physical security of our plants and made the entire City safer for our residents".

A ceremony will take place at 8:30 a.m. on Wednesday, Feb. 16 in Canal Park, 1900 N College Avenue. The event will be held in the parking lot at the south end of the park located on Marigold Lane. Free Parking is available.

In addition to the removal of gaseous chlorine, the ceremony will celebrate the partnerships between the City of Tempe and the residents of north Tempe. 

The Greenline project is a collaborative effort between the City of Tempe, Arizona Historical Society, and the Arizona Water Protection Fund to enhance and restore a riparian habitat in Papago Park.
