Chabot Space & Science Center

Chabot Space and Science Center

During the Fall of 2012 the Chabot Space and Science Center was retrofitted with a 2825 Gallon Tank and Rain Garden. Dig Cooperative, Inc. designed and built a system to catch, store and release rain water to irrigate a California native plant garden and reduce erosion on site and downstream. The system will soon be integrated into the tours and curriculum as a model of watershed stewardship.

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

LEED platinum home

DIG Cooperative Inc. designed and built a comprehensive greywater, rainwater catchment and biofiltration system for this home exceeding L.E.E.D. Platinum standards including 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.

Berkeley EcoHouse

The EcoHouse

At the EcoHouse, a program of the Ecology Center, DIG Cooperative Inc. designed and installed the City of Berkeley's first permitted greywater system as well as California's first residential Constructed Wetland for the treatment of greywater. The following year, DIG led a volunteer rainwater catchment workshop which successfully installed a 1100 gallon Rainwater Catchment system and Earthworks garden in one day.

San Francisco Zen Center / Green Gulch Farm

Rainwater Tanks at Green Gulch

This green point-rated project in Marin County integrates two 2500 gallon tanks, supplying enough rainwater to supply four flushing toilets for most of the year. Stormwater overflowing from the tanks leads to an on-contour swale, which harvests rain before flowing into the local creek. This multi-unit dwelling's design results in an energy consumption decrease of 90% over normal to-code buildings.

Skyline High School

Raintanks at Skyline High

DIG Cooperative designed and installed a 5650 Gallon Rain water Catchment System and Rain Garden at Skyline High School in partnership with the Oakland Rain Barrel Program and prime contractor, The Watershed Project. The project installation incorporated green job training for Program interns as well as an educational public workshop.

East Oakland Boxing Association

Rainwater tank and hand pump at EOBA

DIG Coop collaborated with the City of Oakland Redevelopment Agency to provide a Green Job Training Program at the East Oakland Boxing Association (EOBA) facility. Twelve EOBA interns and several volunteers graduated as Apprentices following a three month build-out and retrofit of the garden and facility. The project features dual flush toilet conversions, rainwater harvesting and irrigation systems, and greywater irrigation to an orchard planted with drought-tolerant, native plants.
