Peshastin-Dryden Wastewater System

In 2016, Chelan County PUD informed the community of a project needed to meet Washington State Department of Ecology water quality standards. The PUD had planned to build a pump station and pipeline to move wastewater from Dryden to Peshastin where phosphorus would be removed in the treatment process prior to discharging to the river. The pipeline was to be the first phase of a two-phase project to improve water quality in the Wenatchee River.  The second phase was to include treatment system improvements at Peshastin to increase phosphorus removal.

A pipeline route had been chosen in May 2016 based on community input. The PUD had indicated that pipeline design would be conducted in 2016 and anticipated construction would begin in 2017.

Pipeline design continued and cost estimates were updated in 2016. The estimated project cost dramatically increased and the PUD determined the project is no longer feasible for the wastewater utility. Therefore, the PUD has halted design of the Dryden to Peshastin pipeline project.

The PUD is continuing discussions with the Washington State Department of Ecology to develop a more cost effective solution in Dryden to protect Wenatchee River quality.

Peshastin treatment system design improvements are underway to reduce phosphorus discharge to the Wenatchee River.

We will notify residents and property owners when more information is available. We will continue to update this website regularly.
