You'll probably get a good crop of self-sown tomato plants

During the floods of last week, Thames water sewage plants couldn't

up and out of the drains... right into our back garden.

The result was 3 days of 6in deep sewage filled water covering a large
expanse of lawn and patio. Luckily none got in the house, but it is
the
garden that I am concerned about.

After 3 days, the residue of sewage remained (the water soaked away),
and
1
week later I am stil waiting for the "professional" clean-up of this
toxic
stuff.

Question: Will the sewage adversely affect the lawn, or the Apple tree
(eaters), or the large clematis that it soaked? If this is not a bad
thing... will the "clean-up" with powerful detergents do more harm than
good?

If it is domestic sewage, and you don't use too many of the most toxic
household chemicals, then it will do little harm. Effectively, it will
break down as the weather warms up and be a general fertilisation. You
may well get localised damage from burning and smothering, but probably
no more.

There is a significant chance that the clean-up will do massive damage,
depending on what chemicals and techniques they use. I have no
expertise
here, but I would be VERY cautious before allowing such a thing to be
done to my garden - even for free.

Why do you think that it is toxic? Human excrement isn't particularly
toxic, even if you do eat at MacDonalds.

Slough sewage works distribute some stuff called cinagro!

Which is just sewage after treatment.

So I would say if it isn't causing any other problems leave it alone.
