Incorporating a natural wetlands as part of the tertiary water treatment process, the Ellis Creek Water Recycling Facility is a sustainable campus of buildings and landscape. The facility includes an Operations/ Maintenance/Lab Building and multiple process structures.

Materials include a low slope green roof, high fly ash concrete, concrete masonry, metal roofing, copper siding and low VOC interior finishes. The building was designed to meet LEED Silver standards. Sustainable design elements include clerestory daylighting, exterior sunshades, interior light shelves and an indirect/direct heat exchange HVAC system. The tertiary treatment ponds create a natural landscape amenity and wildlife habitat, with open space walking trails connected to the adjacent park. Along the trails, interpretive signage explains the treatment process.
