Does anyone have a definitive answer. I have several gateways where the pipe is blocked. One is to a private house. the other two are to arable fields. If they need replacing or just cleaning whose job is is.? The local authority, the landlord of the fields in question or the tenant of the fields in question. The blockages are causing temporary flooding close to some properties. The gateways connect up ditches that are all running along the main road, definitely a meter of less next to the road.
