Salesforce Tower
A towering commercial office building with a 5.4-acre park
Salesforce Tower is a 61-story skyscraper located in San Francisco. With more than 1.4 million square feet of office space, this towering project is home to the largest onsite blackwater system in a commercial high-rise in the U.S., designed to recycle up to 30,000 gallons of wastewater per day. Water from the building’s rooftop rainwater collection, cooling towers, sinks, toilets, and urinals is collected and treated onsite, then circulated for reuse in the HVAC system and for all toilet flushing.
The building reuses 7.8 million gallons of per year—the equivalent of 60 million bottles of water—reducing the building’s freshwater consumption by up to 76%. Epic Cleantec was brought in to assume control of the daily operations and maintenance of the system, including overseeing final startup and commissioning, for this LEED Core and Shell Certified Platinum building.
