WB05 - Blazing a Trail in Sustainability: Salesforce Tower's Onsite Blackwater System

Tuesday, November 13 from 11:30 AM to 12:30 PM | 185D « Back

Abstract Text:

In collaboration with the City of San Francisco and Boston Properties, Salesforce announced they will install a blackwater system in Salesforce Tower, making it the first partnership in the U.S. between a city government, a building owner and a tenant to support blackwater reuse in a commercial high-rise building. The panel will discuss how a city government, business, and building management can work together toward a more sustainable future. In Salesforce Tower, wastewater—from cooling towers, showers, sinks, toilets, and urinals—will be collected and treated in a centralized membrane bioreactor (MBR), which works in tandem with the building’s rain catchment system. Once treated, the recycled water will recirculate through a separate pipe system to serve non-drinkable uses in the Salesforce building, like drip irrigation, toilet flushing and cooling towers. The MBR will be the largest onsite water recycling system in a commercial high-rise building in the United States (saving more than 7 million gallons of fresh water a year).
