The Water and Drainage Department of Fingal County Council is the agency responsible for water supply and drainage, water pollution control and public toilets within the Malahide area. They can be contacted by e-mail at Fingal County Council Water & Drainage.

The Malahide Community Forum is concerned at the lack of clearing of road gullies, particularly in the village, which is causing localised ponding during heavy rain, and the Forum has made several representations to Fingal County Council on this issue.
