For all of you Brisbane renovators out there I was wondering if anyone had done substantial renovations where a combined sewer was involved? My neighbours and I are both looking to do some renovations in the next 2 years and we share a combine sewer. Their sewer runs into our yard and then to the main sewer line. I don't think either of us would have problems sorting it out/paying. Do you have to split them? Did the neighbours Pay half? Any other interesting points? Does the order of renovation make any difference?
