The OPW is responsible for a total of approx. 11,500km of river channel, including approx. 800km of embankments, which form part of the Arterial Drainages Schemes completed since 1945.
The OPW keeps these under proper repair and in an effective condition through an annual maintenance programme. Consent is required from OPW to construct, replace or alter a bridge or culvert.
Local authorities are charged with responsibility to maintain approx. 4,600 km of drainage districts. The Arterial Drainage Act, 1945 contains a number of provisions for the management of Drainage Districts in Part III and Part VIII of the act.
