Chelan County PUD is planning improvements to its Peshastin Wastewater Treatment Plant. This project is in response to a 2009 order from the Washington Department of Ecology (Ecology) that identified phosphorus reductions from wastewater plants needed to restore river water quality. In addition to achieving regulatory compliance, project benefits include replacing worn systems, improved reliability and safety. Ecology funding for the $4.1 million project includes a $2.175 million grant and the balance in low interest loan.
Chelan PUD had initially considered pumping wastewater from Dryden to Peshastin for treatment, but abandoned this concept due to infeasible pumping and pipeline costs. Ecology and Chelan PUD continue working together to develop a cost effective treatment option for the Dryden community.
Construction on the Peshastin facility is anticipated to begin in August 2018 and last through the spring of 2020.
We will continue to update this website when new information is available.
