The afternoon session includes presentations on managing changes in construction, and in pipeline routing.  Other case studies include re-purposing a transmission main, protecting pipes for the next 100 years, protecting critical pipelines during construction of light rail in Seattle, and a hydro-electric project collaboration between Portland Water Bureau and Lucid Energy.

Tour of Area Membrane Treatment Plants – Mid-day Seminar

Hosted by the Water Treatment Committee

This half-day seminar will include a guided walking tour of two area membrane treatment plants:  the City of Kennewick’s Columbia River Water Treatment Plant and the City of Pasco’s West Pasco Water Treatment Plant.  Operators from each plant will lead the tours and provide an overview of the treatment process, describe how the plant works, and answer questions about the plant.  The seminar will start mid-morning and begin with a bus ride from the conference center to the Columbia River Water Treatment Plant.   Following the morning tour and lunch break at the Columbia River Water Treatment Plant, attendees will take the bus to the West Pasco Water Treatment Plant.  The seminar will end mid-afternoon with a bus ride back to the conference center.  Box lunches will be provided for all attendees.
