Grit

[sidkid]

What happens to all the tons of grit that are spread on the roads year after year. I'm guessing that most of it is washed into the drains but then surely the sewers would become clogged over time? (not sure what section to post this in so went for this one...)

much of the grit is salt which dissolves and is washed away.

I think it is rock salt.

There was a disturbing link by an aber on here a short while ago that in her area they mix the grit with anti-freeze which could be harmful to your dog and other wild-life.

Yes I saw that post cupid, I have a feeling it was Ann that posted it.

It accumulates at junctions & by traffic islands waiting for some poor motorcyclist to hit it & fall off/over

Yes, the grit gets washed into the drains. But it is a statutary requirement that local councils clear these drains on a regular basis, e.g....

Some of it can rot away your car chassis too.

Cars are better protected these days but I still get the hosepipe under the wings occasionally during the gritting season.
