Geosynthetic Lining Systems

Irwin Creek Equalization Facilities


In 1999 the engineering firm of Camp, Dresser & McKee was examining the options available for a subsurface drainage system as part of the Irwin Creek Equalization Storage Basin for Charlotte-Mecklenburg Utilities in Charlotte, NC.

This facility presented a significant challenge due to the 2:1 slopes present on the side walls of the basin. Initial consideration was given to placing free-draining aggregate in the subsurface drainage system; however, an alternative was sought due to the logistics of grading aggregate on 2:1 side slopes.
