The building was celebrated for having obtained a “LEED for Homes” sustainability certification and was the first to implement the use of both stormwater and graywater to supply toilets and irrigation, according to the lawsuit.

Microgrids could keep energy flowing at the neighborhood level, while graywater systems and other household installations will help transform properties and communities into their own miniature water districts that are less reliant on external supplies that can face outages and strain.

Non-native plants include African Basil, “which the bees love,” Cordeal says, as well as Meyer lemon and Hass avocado trees, which the couple feed with water from their bathtub through a graywater system installed by Greywater Corp.

“We want a veggie garden and another fruit tree that can use graywater. We want a lot more foliage in general to cool the backyard. We also need to figure out lots of play space for our two boys, but we’re not sure what ground cover that will be.”

San Francisco, for example, now requires large new developments of 100,000 square feet or more to install onsite reuse systems, such as graywater or stormwater systems, for irrigation, toilets and other nonpotable uses.
