Wastewater from Long Creek and Paw Creek Basins is currently pumped about 27 miles via two pumping stations to McAlpine Creek Wastewater Treatment Plant in Pineville. For several decades, the area near where Long Creek empties into the Catawba River has been examined as the site of a new wastewater treatment plant. In 2007, a wastewater master plan identified the need for additional wastewater capacity for the Charlotte Water system, including a new facility to serve the western portion of the county. Work was initiated in 2007-2008 to find a collaborative, regional approach to wastewater treatment in the area.
The Long Creek Regional Wastewater Treatment Plant (LCWWTP) is planned to be a regional approach to wastewater treatment for not only Mecklenburg County, but for the Belmont and Mount Holly communities in Gaston County. Studies have indicated that this would be the most feasible and cost-efficient solution for wastewater treatment for the towns and western Mecklenburg County.
