Coming upgrades to Oklahoma City’s water system include plans to begin pumping treated wastewater back into Lake Hefner.
The Water Utilities Trust on Tuesday agreed to a five-year, $1 billion plan that includes work on a second pipeline to ship drinking water from southeast Oklahoma, steps to integrate separate parts of the water distribution system, and improvements to enable reuse of water from Oklahoma City’s Deer Creek wastewater treatment plant.
Treated wastewater would be of a consistently higher quality than the variable river water feeding Lake Hefner, said Marsha Slaughter, the utilities director.
