Sentral Chorus in San Francisco.

Sentral and Epic Cleantec, a water reuse technology company, have partnered on greywater reuse systems in two Sentral-managed multifamily buildings in San Francisco. The fully operational systems are installed at Chorus at the intersection of Hayes Valley, SoMa, and the Mission neighborhoods and The Landing in the Dogpatch neighborhood.

The Chorus system will recycle up to 2.9 million gallons of water annually, and The Landing system will recycle up to 1 million gallons of water annually. The recycled water will be reused on-site for toilet flushing, cooling towers, and irrigation to significantly reduce water usage in both buildings.

“On-site water reuse is not just a sustainability initiative: It's a vital component of responsible urban development, especially in a water-stressed city like San Francisco,” says Roman Speron, chief development officer at Sentral. “Sentral is now the first multifamily management company with two active and approved on-site greywater reuse systems in the city. Through our partnership with Epic Cleantec, we are not only alleviating strain on municipal water supplies but also fostering a culture of environmental stewardship across our communities.”

Home to the City Ballet and Chorus Hall, Chorus is a 467,000-square-foot luxury apartment building pursuing LEED Gold certification for its energy-efficient design including use of locally sourced material. The Landing is a 308,000-square-foot multifamily apartment building with smart-home technology and sustainable features such as Tesla sharing.

“We are working with pioneering partners like Sentral to catalyze a movement toward more efficient, environmentally conscious water usage within the heart of our built environment,” says Aaron Tartakovsky, co-founder and CEO of San Francisco-based Epic Cleantec. “By harnessing innovation and technology, we are empowering building owners and operators to play an active role in shaping a more sustainable, water-resilient urban landscape.”

San Francisco is leading the nation in implementing on-site water reuse technologies to help conserve water and fortify the city against ongoing drought, Sentral notes. New developments of 100,000 square feet or more are now required to install and operate on-site water reuse systems. In November 2022, Epic Cleantec unveiled the area’s first approved and operational on-site water reuse system at a 40-story high-rise apartment building in downtown San Francisco.

“We are thrilled to partner with Sentral building management and Epic Cleantec, activating new water recycling systems at two more multifamily buildings in San Francisco. This expands the city's diversified water recycling portfolio while setting the example for sustainable real estate development in San Francisco,” says Paula Kehoe, San Francisco Public Utilities Commission director of water resources and chair of the National Blue Ribbon Commission for Onsite Non-potable Water Systems.

“Increasing and maximizing the use of recycled water in buildings and facilities demonstrates San Francisco's global leadership and stewardship to use water efficiently. We applaud our partners for taking a leadership role in environmentally responsible development.”
