The Northeast Ohio Regional Sewer District (NEORSD) Southerly Wastewater Treatment Plant in the Greater Cleveland area is the recent recipient of the Envision® Silver award for sustainable infrastructure from the Institute for Sustainable Infrastructure (ISI). Typically applied at the planning and design stages of infrastructure development, the Envision system rates infrastructure projects across the full range of environmental, social, and economic impacts. For the NEORSD Southerly Plant, a pilot initiative was undertaken in which Envision verification was pursued well into the plant’s operational life, making this the oldest infrastructure project that has been verified by the Envision sustainable infrastructure rating system.
The original NEORSD Southerly Plant became operational in 1928, and underwent a major rehabilitation of in 1974 with investments of $400 million. More recently, the construction of a Renewable Energy Facility (REF) at the Southerly Plant became fully operational in 2014 and the construction of the REF facility was a key driver to pursuing Envision verification for the facility.
The NEORSD Southerly Plant is located in the Village of Cuyahoga Heights, Ohio on a 288-acre site and it serves a population of more than 530,000 in the Greater Cleveland area. The Southerly Plant is the largest of the district’s three wastewater treatment plants and is among the largest of its kind in the United States, handling an average daily flow of 120 million gallons per day (mgd).
