TD Council Approves New UV Disinfectant System For Treatment Plant

The Dalles City Council has approved the purchase of a new ultraviolet light system to disinfect treated wastewater before it is discharged into the Columbia River.  The current UV system in the municipal wastewater treatment plant is 20-years-old, at the end of its useful life, and has components that are obsolete and unavailable.  Mayor Rich Mays says the replacement is part of the constant monitoring the City does to ensure the wastewater plant is in compliance with state and federal environmental quality regulations.  Total cost for the replacement is estimated at around $380,000.
