Watercourses
All watercourses, including rivers, ditches and streams, are the responsibility of riparian owners to look after. You are a riparian owner if your property or land is on, or borders, a watercourse. Riparian owners have a duty to keep the watercourse clear of any obstruction to flow. Hampshire County Council can serve legal notices on riparian owners to deal with obstructions. Please see the Hampshire County Council leaflet on Riparian Ownership for more details. For further advice, please email fwm@hants.gov.uk
Flooding from groundwater
In areas with high groundwater levels, flooding can occur. Groundwater flooding typically affects basements and low-lying land. If you experience groundwater flooding, please contact Hart District Council at drainage@hart.gov.uk.
