No drainage, what now?

[Noidea123]

Morning,

I have done patios before in previous homes of mine which have turned out really well, however I have stumbled across an issue.

My current home has bad clay and terrible drainage. There is no where for the rain to 'fall away' as its a built up area. I was going to install a linear drainage to the sewer mains but we have non that I can find in the back garden!!!

It a weird property in that all our gutter flows connect to next doors and go down the side of their house into a joint flow away???

From what I can see the rest of the sewer flow is at the front of the house.....

What can I do in this instance? Where I have dug the patio ready to be laid its retaining about 3" of rain water when we have a couple of wet days..... I'm paranoid this is going to happen if I just lay the slabs and water sit on top of them causing all kinds of headaches.

I did look at next door and they have no drainage whatsoever, just plain slabs laid with a very similar layout to mine.

Can I build a sump pit say 4ft x 4ft and back fill it under the linear drainage?

I'm stumped what to do.

Thanks,

It's hard to give any suggestions without a few photo's, a rough sketch or at least a description of the area in question.

I have managed to draw (badly) the layout of my garden.

As you can see from the diagram in my pictures, the patio would be directly outside my conservatory doors.

To the left and right are the neighbours.

My guttering runs onto next doors flowaway....

Can't see any way that a drain can be connected to sewerage and the end of the patio is only about 3m from the house so don't think I could do a soakaway.

Should also add that the border around the patio will be a wooden retaining wall upto a hight of 1.2m so it's level with the grass top area.



Thanks.
