Plus all the autumn leaves and other detritus that overflowss into
the foul system after heavy rain.

This is why Southern water used a Tunnel Boring Machine to make a vast
chamber that runs the length of Brighton Promenade to catch all this
excess storm water and sewage after torrential rain. Then it can
be pumped out and 'treated' before being pumped a mile or so out to
sea off Peacehaven I think.

30 years ago there was a pressure group called SAS, Surfers against
Sewage, based in Brighton I think because of the problem with untreated
(and not even filtered) sewage in the sea off the Brighton coastline.

Its not just chip shops. The problem is that most of us, unknowingly do put
some fat down the drain, but there are other factors, nappies, wet wipes,
even surplus concrete gets down to the sewers, making for a smelly toxic
solid mass which builds up in places where flow is only intermittently high.
A friend of mine went on a tour of the Brighton Sewers a few years ago, and
was amazed by the stuff that gets down drains.
