The term headworks can mean either:
a) a structure at the head of a waterway diversion.
b) upgrade works that have to be carried out to cater for the additional demands placed on existing or proposed infrastructure as a result of new developments within an area or catchment.


A high density development within an existing drainage catchment for example may result in greater volumes of runoff entering downstream stormwater pipes, necessitating that those pipes be duplicated or up-sized. These upgrade works could be considered to be headworks, and headworks charges may be levied on the developer to help pay for them.
