Reporting drainage problems

Ditches and watercourses

Main Rivers

Main Rivers are the watercourses shown on the Environment Agency Main River map. Responsibility lies with the riparian owner, however the Environment Agency has powers to undertake maintenance of Main Rivers. 

Ordinary Watercourses

Ordinary Watercourses include all ditches and watercourses not designated as Main Rivers by the Environment Agency. Responsibility lies with the riparian owner and enforcement is undertaken by us, on behalf of West Sussex County Council, the Lead Local Flood Authority.  To report any drainage problems where enforcement may be required, please email land.drainage@arun.gov.uk
