Deep Dive into Net Zero Water in the City

December 9, 2020 @ 8:00 am - 10:00 am

The New England Living Building Collaborative is presenting a series of webinars on how water management, water efficiency and water and energy nexus concepts can be incorporated into project planning, design, construction and operation.

Deep Dive into Net Zero Water in the City will focus on urban water reuse, which has recently become practical in Massachusetts Water Resource Authority (MWRA) sewer service communities, due to a 2019 housekeeping rule revision. To introduce how urban water reuse works, case studies from Battery Park City and other projects in New York City will be highlighted, as urban onsite water reuse has been in place in Manhattan since 2002. Onsite water ruse is currently embraced by the NYC Department of Environmental Protection as a means of water efficiency and conservation.
