American Assets Trust developed this mixed-use three-building project that spans four blocks as part of Portland’s Lloyd EcoDistrict. The three buildings share one of the largest natural organic recycling treatment systems in the US, which treats all the buildings’ wastewater (including human waste from toilets) for reuse for toilet flushing, mechanical cooling and below surface landscape irrigation in an urban setting. It was permitted as a Water Pollution Control Facility with two on-site injection dry wells. The project showcases the economic and ecological benefits of district scale onsite wastewater treatment and reuse.
Net Zero Water, Net Zero Energy Full Plane Passive House in Portland
The Full Plane Passive House gives modern form and presence to the owner’s ecological and social values, while providing a playful environment for her son to grow and be educated in sustainable living in the City. To meet net-zero water goals she combined stormwater catchment, graywater irrigation for her living landscape and composting toilets. It all complied with Oregon’s statewide alternative water re-use plumbing rules adopted a decade before many other US Cities even considered it.
