B-roll: Converting wastewater into renewable energy for South Lake Union campus

King County’s Wastewater Treatment Division and Alexandria Real Estate Equities, Inc. are partnering to draw heat from a large, underground sewer pipe to heat a 1.6 million-square-foot mixed-use life science mega campus in South Lake Union. This is one of the first large commercial projects in the nation to save energy using sewer heat recovery technology, demonstrating how public-private collaborations can significantly reduce greenhouse gas emissions.
