Drainage Plans

[Canski]

Hi all,

 

As I continue to plan during my wait for my bat licence I was looking at drainage and came up with this design. One of the groundworkers I spoke to suggested picking up the S&VP in the living room in line with the one in the store and then extending the run to the RHS of the building then to the garden room. I thought that S&VP's had to come down to a rest bend which would make a connection at the S&VP in the store impractical.

 

Also would I need a connection for the condense from the ASHP ?

Also maybe I could run the waste from the Utility beneath the stairs into a stub stack in the WC and save a manhole. ??

 

Any thoughts ?

I would not want a branch connection under the floor.  I prefer the below slab runs to be as short as possible.  I would be tempted to move the line from the store so it heads under the stairs.  Makes it shorter and you lose an IC.  From your kitchen, you could have a gulley outside that would be trapped and roddable and take the condense from the ASHP.  That way that bit of the line can't bring gasses into the house.

Thanks Mr P for your reply. Good point about shortening the run by going under the stairs. I wouldn’t save a manhole however as the drainage needs to change direction at the front of the house. A gully outside the kitchen is a good thought and it could take the ASHP condense as well but again I’d need the manhole at the corner for the drain from the garden room.

Thanks very much for taking time to do this @ETC. That looks better. What’s that coming out of the top right IC ? OSVP ?
