"555 City Center's infrastructure is an environmentally certified operating system. It was built to adhere to Leadership in Energy and Environmental Design (LEED) guidelines, a U.S. Green Building Council program that rates new and existing commercial structures for environmental correctness. 555 City Center is also the first high-rise in the Bay Area to be fitted with a dual plumbing system to utilize recycled water for flushing its toilets and for other non-potable uses. This 'purple-pipe' system will eventually connect to EBMUD's Bayshore Recycled Water Project. The goal of this undertaking is to deliver 2.3 million gallons of recycled water per day to businesses in Oakland, Berkeley, Emeryville, Alameda and Albany, thereby saving enough drinking water to serve more than 15,000 homes."
