No. Well, yes, but Building Control will not let you.
Reason being is that foul drains are designed for a known amount of waste, plus some spare for further development, based on a ratio of homes/occupants/number, the further away from the house, the larger the drain, and this water goes to the treatment plant.
Storm drains use a similar ratio to work out the size, but the water does not go to the treatment plant, it goes to the main watercourse, be it a stream or river. The Water Companies don't like having to pay to treat rainwater, and they also don't want the foul drains overflowing during periods of heavy rain, due to rainwater being fed into the foul system. The Storm drains are usually slightly bigger (or change to a larger diameter pipe sooner) than foul drains.
With older properties, they used a communal system, but from the Victorians onwards, there were two systems installed.
