The Reedy River Basin Sewer Tunnel, a $46 million project completed by Renewable Water Resources (ReWa), addresses the growing wastewater needs of Greenville, S.C., as the city experiences rapid population expansion. The gravity-fed sewer tunnel, which spans 1.3 miles was constructed to relieve pressure on the aging sewer system that risked overflows in the downtown area. This underground tunnel provides the necessary infrastructure to support Greenville’s continued growth while safeguarding water quality and the environment.

BILCO’s custom floor access doors play a vital role in maintaining and operating the new tunnel system. These doors allow workers to safely descend into vertical shafts to access the tunnel for inspections and equipment handling. Designed to withstand corrosive environments, these durable and reliable access doors were selected for their ability to meet the demands of wastewater projects.
