Audubon Nature Center - 4700 North Griffin Avenue, Los Angeles
The Audubon Nature Center is a LEED-Platinum certified "green" development consisting of a nature center building complex with adjoining garden and courtyard areas. EPD helped the Audubon Society meet its sustainable development goals by designing a system that treats the building's wastewater for onsite reuse. Because the city does not yet permit the reuse of even highly treated wastewater within a building, the water is presently being used for subsurface irrigation. However, the system is designed to be easily modified to use this water for toilet flushing and other building processes such as cooling once the State Department of Health Services verifies continuous acceptable water quality.
The Audubon's wastewater treatment and reuse system consists of:
- Orenco Advantex hybridized anaerobic/aerobic treatment and filtration.
- Peracetic acid / ultraviolet light advanced oxidation disinfection.
- Discharge to a Geoflow subsurface irrigation system.
Once the city/state approves reuse of the treated water inside the building, there will be an estimated 70 percent water savings over a comparable conventionally-plumbed building.
