Simply Build It

I don't know for sure but I think that sounds ok to me. Rainwater entering sewage drain isn't a problem, if it were the other way around (rain water drain being used for dog foul) then it would be a problem.

I have two inspection covers in my back garden one of which the toilet empties into so when I clean up after my dogs I just lift the inspection cover and drop it down. No different to a toilet being flushed in my opinion!

If anyone knows any different I'd be interested to hear.

Your local area will either have a combined system (foul and storm water into the same drainage system) or will be a separate system (separate pipework for the strom water to the foul sewerage).

lillian123 is right in as much as putting storm water into a foul drain is not as much as sin as the otherway around, but is still frowned on by the waste water board.

Hope this helps
