L.E.E.D. Platinum Home / City of Piedmont

LEED platinum home

DIG Cooperative Inc. designed and built a comprehensive greywater, rainwater catchment and bio-filtration system for this home exceeding L.E.E.D. Platinum standards including 100% of roof surface harvesting area and 100% on-site storm water retention. Several rain tanks were plumbed together beneath a deck to provide almost a full years of rainwater supply for indoor laundry use, toilet and urinal flushing and a living wall.

This family's greywater system, rainwater system overflow and on-site spring/weep are plumbed to a beautiful constructed wetland. The wetland filters water before it is pumped to irrigate up to 75% of the property.

Project Features

  • 8875 Gallon Rainwater Tanks to Indoor Plumbing
