Designed in consideration of its ecological and hydrological setting, Zion National Park’s East Gateway Lodge and Visitor Center will treat effluent with a zero discharge water recycling approach.
Each year, more than four million people flock to the spectacular slot canyons and sandstone cliffs of Zion National Park. Carved by the Virgin River and its tributaries, the geologically and topographically diverse park supports a myriad of habitats. While lodging and visitor facilities are abundant near the park’s western entrance, support facilities are nonexistent at the park’s eastern entrance, which accommodates more than one million annual visitors.
Lacking space for an eastern visitor station within the park, the National Park Service partnered with Zion Mountain Ranch, a local property owner of 8,000 acres of adjacent, private land. With a shared vision to add visitor lodging and amenities, stimulate local economic growth, and create a place that fit within the context of its ecology and watershed, the partners developed a plan for a 190-room lodge and a visitor contact station. The site occupies the edge of the Colorado Plateau, a region with critical water management issues. The landscape, developed for more than a century and used primarily for ranching and second homes, has suffered impacts such as overgrazing, erosion, and habitat fragmentation.
As the ecological and water consultant on Overland Partners’ planning team, Biohabitats provided an ecological framework to guide the project based on an understanding of the interrelationship between the site’s geology, hydrology, and habitat. Using a conservation suitability analyses, Biohabitats recommended management zones and areas for restoration and conservation within each zone. Strategies include creek restoration, wildlife connectivity, stormwater green infrastructure integration and recreational planning. After determining the project’s water footprint and wastewater generation rates, Biohabitats developed two concepts for treating effluent including a constructed-wetland based system as well as a Moving Bed Bioreactor (both coupled with seasonal storage) to treat wastewater from the lodge, visitor center, and nearby properties with aging systems. The project is seeking a ‘zero discharge’ approach by reusing all effluent for toilet flushing and irrigation of pasture lands.
