soak away

[paulpa]

I have a soak away taking rear roofs of property and extension. After talking with the Water board they have said i could run direct to the main sewer.
My question is, i could do this in two ways.
1) dig down and find the pipes then divert to a manhole approx 2 metres away.
2) easier option dig down the side of soak away, put new pipe in from there to main sewer leaving original pipes as they are.

Would option 2 release water from the soak away?

Go for option 1.

Find the pipe, fit a y junction and a trapped gulley, otherwise you will have smells coming back from a combined system.

What fit the trap gulley at the downpipe on side of house?
Why the y connection?
Another option i thought about was just dig a trench from soakaway to manhole fill with rubble creating a type of french drain, just extend soakaway to manhole.

With running the pipe from a soakaway to the manhole you will have all sorts of stuff going into the manhole and could cause a blockage, plus how do you stop the smell from the foul drains.
If theres a pipe you can connect onto, that already runs into the manhole, its just a case of cutting into it, connect a Y junction then run it to the trapped gulley.
If not the run a new pipe into the manhole, you still need the trapped gulley to prevent smell coming back from foul drains.

Hi, yes it was to run the pipe from the existing straight to manhole. Cut hole in side of manhole to poke the new pipe into. ( brick manhole).
So i guess i need to remove some patio, dig down and fit a trapped gully.Or put the gully near the manhole .

Gully goes at the bottom of your down pipe, then find the pipe that runs into your manhole branch into it with a y junction. Best not to break into manhole.
