well first good luck you will need it we have a similar problem and councils are duty bound to clear the highways of water it is there method of doing so that causes the bother
at one time the road to the west of us was quite narrow old leyland tiger buses had to pass at specific points then in the early seventies there were two major construction projects with vast increase of lorries they had a code that the full wagon ran on the road with the empty ones running on the grass bank
the original road drainage ended up silted and buggerd with the road being barreled and lying in water when it rains now councils think that farmers fieldsare there for diverting there piss poor road maintenance water onto we have had numerous confrontations over the years and given them various options to remedy but money is the big issue they got there fingers burned years ago with a developer that had council connections spent thousands doing a road crossing when all that was required was a ditch cleaned there is another field the drainage contractor was working on when he discovered the main drain was silted he just piped it out to the road and now there is water constantly running on the road
the part of the road that affects me everytime they dug a hole through the dyke i filled it with concrete and stones so they could not dig that bit back out which reminds me i have one to fill in this year
anyway as i said good luck from my experiences you will need it
