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                 

Internal Drainage District

The River Arun Internal Drainage District is an area where there is a special drainage need and is currently managed by the Environment Agency.        

Highways

Trunk roads

Drainage issues on trunk roads (road or section of road under the control of the Government) such as the A27, should be reported to National Highways.

Other public roads

Drainage issues on all other public roads in the district should be reported to the Highways department at West Sussex County Council.                

Groundwater and surface water

Flooding from groundwater and surface water should be reported to West Sussex County Council.          

Sewers

Public sewers and lateral drains (drains that sit outside of the boundary of a property) are the responsibility of Southern Water Services Limited. Information on what to do in an emergency, including reporting sewer flooding can be found on the Southern Water website.  

Private

Cesspits and drains serving only one property within the property boundary are the responsibility of the property owner. More information about the transfer of private sewers is available from Southern Water.
