The Nutrient Management Facility, owned by Alexandria Renew Enterprises (AlexRenew), recently earned the first Envision Platinum certification from the Institute for Sustainable Infrastructure (ISI) in the Washington DC/Virginia metro region. The Envision rating system provides a holistic framework for evaluating and rating the environmental, community, and economic benefits of large infrastructure projects that incorporate sustainability throughout the project lifecycle. The AlexRenew Nutrient Management Facility, an 18-million-gallon storage facility topped with a public athletic field, stores wastewater during nutrient peaks to balance the amount of nitrogen that goes into biological treatment processes. The Nutrient Management Facility 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.
