Caerphilly County Borough Council has issued advice on flooding for residents.
A spokesman said: “Over recent years, following flooding incidents, the council has received many enquiries regarding watercourses on private property.
“It appears that significant numbers of the general public are unaware of their responsibility under the Land Drainage Act 1991 to maintain the free flow of water over or through their land. Under the Land Drainage Act this is referred to as the landowner’s ‘riparian responsibility’.
“In practice this means that individual land or property owners are required to keep watercourses and any culverts that pass through their land free from obstruction caused by artificial and natural material – ie if man-made debris or a tree were to cause the watercourse to block, the land owner is obliged to remove the obstruction.”
Councillor Rob Gough, cabinet member for transportation and planning, said: “Drainage is a complicated matter and we want to ensure that residents clearly understand their responsibilities.
“Problems caused by flooding can be devastating so it is important that steps are taken to limit the risk as much as possible.”
The council is also keen to stress there are other drainage systems not covered under the Land Drainage Act. Riparian responsibility, such as private drainage, would also be the responsibility of the landowner.
Other drainage responsibilities would lie with other bodies – eg main rivers (Environment Agency), highway drainage (highway authority), public foul sewers, combined sewers and surface water sewers (Welsh Water).
There are many housing developments where, until the site is adopted, the responsibility for all drainage matters lies with the developer.
