STATEMENT OF FACTS:
1. Wastewater contains heat energy as it flows through pipelines to the treatment plant and can be both a source of heat for buildings and a sink for unwanted heat from buildings.
2. Recovery of heat energy from wastewater is consistent with the wastewater treatment division's mission to recover resources from wastewater.
3. Use of that renewable heat energy reduces use of fossil fuels for heating and cooling, contributing to efforts to reduce the region's carbon footprint, consistent with King County's Strategic Climate Action Plan, and supports countywide greenhouse gas emissions reduction targets adopted as Countywide Planning Policies by the King County Growth Management Planning Council in 2014.
4. In 1992, the former Municipality of Metropolitan Seattle wastewater utility, now known as the King County wastewater treatment division, and the Boeing Company realized the potential to utilize effluent from the Municipality of Metropolitan Seattle's South Treatment Plant in Renton to cool buildings at the adjacent Boeing Longacres building complex, as an early sewer heat recovery system.
5. The Municipality of Metropolitan Seattle and Boeing signed an agreement in 1992 for construction, operation, and ownership of an effluent cooling model project at the site. The agreement expired in 2017.
6. The effluent cooling system was constructed, has been operating successfully since the mid-1990s, and is currently operational.
7. During the term of the 1992 agreement, ownership of most components of the effluent cooling model project passed to Boeing, although the transfer of title to the components may not have been formally memorialized.
