Patio drainage issues

We’ve built a new wall at the back of our property. It’s replaced a fence. We are going to lay a new patio area and are trying to work out what to do about drainage.

the gutters drain to somewhere under the patio. We haven’t dug it up yet but I imagine it’s a bodged Soakaway or something like that.

But....the back wall is only about 6-7m from the house. Regs state Soakaway must be 5m from house and 2.5m from boundary line. Which just isn’t possible. 

We also have clay soil. 

I’m concerned about the Soakaway being too close to the garden wall - will it undermine the wall foundations?

we can’t run a drain down the side of the house.

so I’m really confused as to how to solve the problem.

any ideas?

    Surely your gutters are tied into your drains

    No. They run off into the garden. I haven’t dug them up yet but my guess is it’s a perforated pipe.

    Is it an older style house? Is there a rodding point for the foul drain at the back, presuming the drain runs back to front?

    rain water on domestic properties should not run into mains drains, they should be connected to a soak away (this is to comply with building control regulations) if all rain water went directly to the drains the country would be flooded every other week in winter. Very rarely are they built in a satisfactory manner and it's usual to find you can't meet the distance limits from house and boundaries. A true soak these days should be built with the plastic cage frames with a permeable fabric liner over before back filling, thing is in winter the water table can get so hi that they are permanently full of water. If you had a proper footing put in then the wall should be ok

    Apologies should've asked if there is multiple rodding points which would indicate a separate storm drain.  Only way to be sure is dig down and see what you have got underneath, then you can get better advice
