February 21, 2011—Worrell Water Technologies, a leader in ecological wastewater re-use technology and innovation, announced that the San Francisco Public Utilities Commission (PUC) selected its Living Machine system for on-site wastewater treatment and water reuse in its new office building located in the heart of San Francisco.
Designed with cutting edge, green building technology, the new San Francisco Public Utilities Commission’s administration offices will be a 13-story, 277,500-square-foot building that generates its own energy through integrated solar panels and wind turbines, and treats and recycles all wastewater for re-use with an on-site Living Machine system.
The Living Machine system will be integrated into the lobby and outside landscaping, taking all grey and black water from the building and treating the water through advanced ecological engineering. The system is composed of enhanced wetland processes treating up to 5,000 gallons of wastewater per day. The wetlands require only about 1,000 square feet and that area provides green space, supporting a host of lush plantings. Wastewater will flow below the wetland surface in watertight cells so there is no smell, mosquito habitat, or health hazards.
The treated water will be re-used for toilet flushing. The SFPUC projects that the Living Machine system will allow the building to save approximately 750,000 gallons of water per year, with an additional 900,000 gallons available for nonpotable future uses.
