A Headwall (also Endwall) is a small retaining wall placed at the inlet or outlet of a stormwater pipe or culvert. It serves to minimise vegetation growth and reduce erosion around the culvert inlet and outlet. Although the terms headwall and endwall tend to get used interchangeably it may be more correct to call a retaining wall at a pipe inlet a headwall and a retaining wall at a pipe outlet an endwall.7
