Feasibility of energy recovery for heat pump-assisted district heating and cooling from the Metro Renton wastewater treatment plant and effluent transfer system
The Municipality of Metropolitan Seattle (Metro) is constructing a 12-mile effluent transfer system (ETS) from its Renton wastewater treatment plant to Duwamish Head on Puget Sound. The preliminary stud (Phase I) concluded that the Renton treatment plant's effluent could feasibly sustain large amounts of heat pump output, i.e., 500 to 800 million Btu per hour. Further, the study identified eight locations along the ETS where district heating and cooling (DHC) networks could be favorably established to serve existing businesses and/or new growth. In December 1985 this second phase study was commissioned as a detailed assessment of specific customers in several of the recommended DHC development areas. The potential customers evaluated in this report include: Seattle-Tacoma International Airport, the Container Corporation carton manufacturing plant adjacent to the Renton treatment plant, Metro Transit Department's South Base, two buildings at the Boeing Developmental Center, and the Valley 405 Business Park adjacent to the Renton treatment plant. These potential users of effluent-based heating and/or cooling have been evaluated in terms of their heating and cooling demands, the type of effluent-based heat pump system necessary for serving them, and the economics of the effluent-based energy approach. In the cases of Sea-Tac and Container Corporation, the assessments also examine environmental and institutional issues, and generalized feasibilities for financing effluent-based systems.
