Surface water drainage - Front drains to soakaway at rear

[Dvdmarm]

Building regulations on a new build state that surface water from two down pipes at each of the front corners of the front of the property must drain to a soakaway at the rear. In this instance, the only route available is beneath the building.
I'm assuming that the pipes would connect to a single pipe via an access point before making its way to the rear of the property and terminate at the soakaway, but need to check on the correct procedure.

All advice greatly appreciated.

Haha lpad, Flowjoe is the expert

Have you got some photos etc or plans why does it have to go under the house is there no room to squeeze it down the side under a path. On a new build I highly doubt they'd have let you build right upto the boundary on both sides.

You going to struggle that if your downspouts are on the corner and you are flowing to the back of the property you can't really flow forwards to flow backwards.

So you are going to have to run two lengths meeting at the back of the house in an ic then run that into your soakaway 5 metres from the house,

Have you got enough fall? You're going to have to lintel it every internal footing wall you pass through.

I'd go with the two runs to the soakaway. A junction needs to be within 12 metres of a rodding eye. 150ml pipe run.

Many thanks for replies. Unfortunately the side walls are right on the boundaries, therefore the only route to the rear in this instance is under the house. Building control's insistence about this seems to be a bit bloody minded, they refuse to allow it to drain via a sealed trap to the foul system via an IC at the front. Looks like we're going to have to tow the line with the two lengths as suggested. Thanks again!
