State Adopts First Reclaimed Water Rule

Posted

A new rule from the Washington Department of Ecology intends to streamline the process for reclaiming water, which can be used for irrigation, landscaping, flushing toilets or recharging groundwater. 

The rule requires that reclaimed water projects protect public health and water quality, according to a press release from Ecology. It creates statewide standards and creates a predictable permitting process for reclaimed water projects, according to a press release.

The rule comes after a decade of work with the Washington State Department of Health, utilities and other stakeholders to develop standards, as well as a project planning, design and permitting process.

“It addresses all aspects of reclaimed water; including permitting for generating, distributing and using reclaimed water across the state,” stated the release.



The rule will go into effect on Feb. 23. To reclaim water, technology is used to remove contaminants and pathogens from wastewater so it is safe to be used again. According to Ecology, reclaimed water is a key component for managing the state’s waters wisely and can protect resources for future generations.

“We’re proud of the effort that has led to this new rule,” Ecology Director Maia Bellon said. “Reclaiming water can help Washington communities prepare for and recover from droughts. By expanding options for reclaimed water use, we can help Washington communities use the right water for the right use.”
