During the 1990s, the City of Wilmington and New Hanover County experienced a 30 percent growth rate, taxing the wastewater infrastructure for both the City and County. The City and the County have separate wastewater collection and pumping facilities. However, the City owns and operates two wastewater treatment facilities that handle the wastewater from the City, County, and the City of Wrightsville Beach. The City's wastewater treatment facilities currently discharge wastewater that meets secondary standards into the Lower Cape Fear River. NPDES discharge permits for both facilities are up for renewal, and the State of North Carolina is expected to impose strict effluent discharge limits.

The rapid growth, anticipated discharge limits, and need to develop, provide, and fix the existing wastewater infrastructure required the City and the County to perform a wastewater master plan. They decided to perform a joint master plan, rather than develop separate plans, since both systems utilize common pump stations and interceptors to convey wastewater to the City's two wastewater treatment facilities.
