Description

The separate rainwater and greywater treatments will meet SFPUC’s stringent requirements following a risk-based approach for water quality and safety.

Rainwater treatment will use proven treatment methodology from Aqua Treatment Services (ATS) which exceeds typical treatment for non-potable applications. The Greywater treatment uses Aqualoop technology, the only process certified for NSF350 C commercial scale greywater recycling for indoor non-potable uses.   Following Aqualoop, NSF350 C water passes through additional treatment to meet SFPUC requirements.  This treatment uses EPA 3rd party certified treatment for potable surface water, also provided by ATS. The treated rainwater and greywater will be the primary sources of water for toilet flushing in the 422,000 square foot complex. By collecting and treating water onsite the use of municipal water demand will be reduced by at least 25%.

Collaborative System Design & Implementation

The water system was designed by local San Francisco firm, Heat Transfer Equipment Company (HTEC) in close collaboration with Ecovie of Miami Beach FL. 

HTEC is the sole provider of Aqualoop technology in Northern California & Ecovie is the exclusive distributor in the U.S.
