OPW Flood Defence Schemes are generally carried out under the Arterial Drainage Act 1945 and the Arterial Drainage Amendment Act 1995, although in recent years some phases of schemes have been carried out by the Local Authorities under the Planning and Development Regulations. The OPW either works in association with the relevant Local Authorities or funds Local Authorities directly to undertake flood defence works.
