Project Merit: Water


Alexandria Renew Enterprises (AlexRenew) and CH2M (Englewood, Colo.) for the Nutrient Management Facility (NMF), which recently earned the first Envision Platinum certification from the Institute for Sustainable Infrastructure in the Washington DC/Virginia region. An 18-million-gallon storage facility topped with a public athletic field, the NMF stores wastewater during nutrient peaks to balance the amount of nitrogen that goes into biological treatment processes. The NMF is the largest project under AlexRenew’s $160-million State-of-the-Art Nitrogen Upgrade Program, the utility’s response to regulations limiting the amount of nutrients water resource recovery facilities can release into the Chesapeake Bay watershed. The NMF’s dual-purpose nature, improving the health of local waterways while engaging the community with beneficial greenspace, was crucial in achieving Platinum certification. Other sustainability efforts included using local and recycled materials, recycling construction waste, recovering a brownfield site, expanding stream buffers, using sustainable stormwater practices, and employing energy and water monitoring systems.
