Land drain

Hi all. I am a total newbie to this, but this site has helped me.

I discovered water underneath my floorboards last year, apparently it is a bit of a problem in the surrounding area. The house is beside a
natural stream which has been culverted with concrete and gets pretty high during the wet weather, this runs along the back of the house. Its a detached dormer bungalow.
The ground is pretty clay like and the water table in the area is high so I gather a soakaway will not work. What I am doing to combat this problem
is digging a trench at the back from one end of the house to the other deeper than the ground is under the house. I will have this sloping slightly following
the natural lye of the land and hope to connect it to a mains surface water drain that runs down the side of the house, via a rigid 6inch pipe with holes
at the top covered with pea gravel. Will this help alleviate the problem under the house? Is there something else I can do? Also should I not get permission
what else can I do? I am also thinking of doing similar at the front of the house.

I am assuming this is a okay plan. I have the trench dug, I am now using flexible 4inch pipe instead, hopefully going to start laying the pipe today.

Well it's done. I have gone into a conveniently located surface water inspection chamber rather than break into the pipe. Thanks for the great advice! ha.

this may come as a surprise to you but some of us have to work bank hols for the jam. if you have a stream under your house then digging down and putting in a bit of drainage wont work. you should be thinking along the lines of tanking which will cost an arm and a leg. especially if it has to be done on a bank holiday.

bank holiday == double bubble mmmm
sounds like a fair plan,it may be an idea to dig down around the foundations and tank the lot ,but this will be messy ,wait and see how your drain performs first
as a builder i have never bought a house on a hill,near water,without a drive and underneath 100 ft trees
all these things cost a fortune to rectify when they go sideways
