Description

At the NREL office complex in Denver, Colorado, a forward-thinking approach to water sustainability is brought to life through the implementation of an advanced greywater recycling system. Designed to treat approximately 1,429 gallons (5,400 liters) of greywater per day, the system plays a key role in reducing potable water consumption and supporting environmentally responsible building operations. In this project, greywater from showers and lavatories is captured, treated, and reused for toilet flushing across the facility. This smart reuse strategy significantly lowers the demand for fresh drinking water—an increasingly valuable resource in water-stressed regions. To meet strict local regulations, including Colorado Regulation 86, the AQUALOOP greywater system is based on an NSF 350 Class C certified solution, ensuring safe and reliable water reuse for non-potable applications. A pre-assembled, AQUALOOP GW5400 system was selected for its treated water quality, compact design, and ease of installation. At the heart of the system is the membrane ultrafiltration technology, delivering consistently high water quality. The standardized, above-ground configuration allows for fast deployment and simplified maintenance, making it an ideal solution for modern commercial buildings. This project demonstrates how innovative water reuse technologies can seamlessly integrate into everyday infrastructure—transforming greywater into a valuable resource and setting a benchmark for sustainable building design in the United States.
