Port Angeles Water Treatment Plant

Purpose:
The City of Port Angeles has historically obtained its potable water supply from a Ranney collector along the Elwha River, located about three miles upstream of the mouth of the river.

Because the Ranney collector draws both groundwater and surface water, the city’s water system has not been in compliance with drinking water standards. Water quality would be further affected by dam removal and the subsequent release of accumulated sediment.

The new Port Angeles Water Treatment Plant (PAWTP), which became operational in February 2010, allows the city to comply with water quality standards during the dam removal process and into the future.

Design:
The PAWTP is designed to provide up to 10.6 million gallons of treated water daily to the City’s water distribution system. The majority of water during dam removal will come from the Ranney collector, or the Elwha Water Treatment Plant when necessary.

Primary elements of the facility include an Actiflo/filter/clearwell/administrative building, a concrete backwash holding and recycle storage basin, and a concrete sludge drying bed with a sand layer for drying.
