Looking for some advice on soil pipe routing in a bungalow. Red is sewerage, blue is grey water. Both will end up in on site waste water treatment.

 

I was going to put a stack on the end of the red pipe up through the roof. I was also going to run the blue pipe into the attic and connect into the red stack to vent or else give it a separate vent.

Thanks Dave,

 

Yes new build. My thoughts were to bring the pipes straight out to minimise pipes under the foundation where I can't get to them.

 

Also I was advised to bring washing machine and kitchen through a grease trap before entering the treatment plant.

 

Does it matter where in the 'circuit' I connect the stack? There will be no drains into it just a vent.

why not take the LH drains the other way, joining the end of the red? a much shorter run, if the falls will allow it.

save 15m of drain and some chambers.

One reason would be to avoid a drain pipe under the building.

Thanks ETC that's very helpful. What are the BIGT?

 

For the drains from sink bath etc I was going to use the detail below. I don't have any stud partitions to pipes in so was going to run 110m drain to each point.

 

From reading regs I need to make sure there is at least 450mm from connection to drain and invert so I suppose that will set my level and I will install the treatment system as required by pipe falls.

Have you got enough elevation in the ground levels for the drainage fall to go round the outside of the build, or will you need to dig a really deep hole for the treatment plant invert?

I'm getting tired of this. Your messages are either good practical advice or this hatred of others. 

The former is all that stops me blocking you.

Please give out advice not hatred.
