My back garden is very poor quality soil which is shallow on top of shale then clay,it is always waterlogged. Can I drain it into the foul water system.

Is there no surface water system present, Frank? Draining into the Foul is a last resort and needs to be 'trapped' to prevent bad smells escaping.
