Hannah Mason Pump Station to Deliver Ongoing Savings to Customers and Reduce Carbon Emissions

Oversized check presented to Portland Water Bureau

Earlier today, the Energy Trust of Oregon (Energy Trust) presented the Portland Water Bureau with a check for nearly half a million dollars in front of City Council – an incentive that will benefit Portland Water Bureau customers.

This incentive was awarded to the Water Bureau’s new energy-efficient Hannah Mason Pump Station, which replaced the old 1912 Fulton Pump Station.

Pumping water uphill is the Water Bureau’s largest single use of electricity, system-wide. Making pumping more efficient saves energy and money and reduces carbon emissions.

By combining energy-efficient pumps, an innovative pump station design, and the properties of gravity, the Portland Water Bureau is cutting annual energy costs by nearly $163,000 and also contributing to achieving goals outlined in the City of Portland’s award-winning Climate Action Plan.

“The new Hannah Mason Pump Station supports a citywide goal of reducing energy use by 2 percent,” said Portland Water Bureau Administrator Mike Stuhr. “Energy Trust’s assistance allowed the City to make a major contribution to meeting these goals with an investment that will pay for itself in only 3.3 years.”

Energy Trust Partnership

Energy Trust provided technical assistance on the project which enabled the Water Bureau to identify an estimated annual savings of 2.37 million kilowatt hours. The carbon equivalent for these savings is 610 metric tons, or approximately 1.345 million pounds, of CO2 reduction.

“We commend the Portland Water Bureau for seizing the opportunity to rethink how to efficiently deliver water to the residents of the city’s west side,” said Energy Trust Executive Director Michael Colgrove. “We’re excited to be part of this project that not only saves energy, but improves the overall quality of the pumping system while providing benefits to both water and electricity ratepayers.”

How Energy Is Saved

Map of location of new Hannah Mason Pump StationHannah Mason Pump Station receives electricity from Portland General Electric and draws water primarily from the city’s Washington County Supply Line. The old Fulton Pump Station drew water from the Southeast Supply Line. With an average hydraulic elevation approximately 125 feet higher than the old Fulton Pump Station, the Washington County Supply Line requires less pumping, enabling the Water Bureau to use three energy-efficient, 150-horsepower pumps to meet most of its pumping needs. This cuts pumping energy by approximately 45 percent, annually.

In addition, Portland Water Bureau opted to use hydraulically-operated butterfly valves for pump control which reduces the head pressure the pumps must provide, reducing energy use another 14 percent compared to more traditional diaphragm control valves.

Hannah Mason Pump Station

Hannah Mason Pump Station is the first Water Bureau infrastructure project named after a woman. A philanthropist, landowner, and widow of Portland Mayor William S. Mason, Mrs. Mason owned most of the land on which Willamette Park sits today.
