Story

The deadline for local developers to submit ideas on harnessing thermal energy in wastewater pipelines to heat, cool and power commercial buildings has been extended to Thursday, Sept. 20.

King County’s Wastewater Treatment Division (WTD) has issued a Request for Information (RFI) that invites local developers and commercial property owners to submit ideas for privately-owned district energy systems that could extract and recover energy contained in WTD’s conveyance system.

District energy systems produce energy from a local plant that can be piped underground to nearby buildings, replacing the need for boilers, furnaces, or air conditioners. Wastewater that picks up heat from people, home appliances, and industrial processes maintains an annual average temperature of about 65 degrees Fahrenheit, warm enough to provide an extractable source of energy.

The County will host an informational meeting for the public on Thursday, Aug. 30 from 3:30 to 4:30 p.m., at King Street Center, 201 S. Jackson Street, 5th Floor.

 King County’s goal through the RFI is to gauge interest within the private sector about investing in new technologies that would make heat energy and possibly other forms of energy contained in its wastewater system more widely available.

The district energy systems outlined in the King County RFI would need to be privately owned and operated, and installed on private property with a connection to a WTD regional wastewater conveyance line. The district energy system could not impact King County’s operations or facilities, and the developer or property owner would have to assume responsibility for costs or risks associated with the project.
