I suppose we use what you would call a two pipe system. There is talk
here of introducing a new third pipe for greywater. That is, water
that
comes from baths, sinks, showers, etc. as opposed to sewerage from
toilets. Difficult to retrofit of course but new estates are likely to
be plumbed this way in the near future.

My parents have a holiday cottage in a tiny village that has no mains
drainage. All the houses have their own septic tank (two-chamber sewage
treatment unit that does more than just store the sewage, as happens with
a
cesspit). However to reduce the amount of water that goes into the septic
tank, all the grey water is piped to a communal "land drain" that
discharges
into a nearby stream. I'm sure that arrangement contravenes almost every
health and safety and environmental law known to man!

Every time I've walked near a septic tank it has stunk to high heaven.

You have no idea how many you have walked near that havent.

They're a disgusting invention.

Better than a cess pit, stupid.

Do many houses have a rainwater drain in the street?

I thought all streets had those - where do you think the rainwater goes
that flows off the road?

That's not HOUSES stupid.

I thought the usual arrangement was for there to be a soakaway under the
lawn for rainwater,

Soakaways don't work, not in Scotland anyway.

Bull****.

The land is already waterlogged, you can't shove more into it.

Bull****.

so the rainwater and grey/sewage water never mixed.

How would a soakaway prevent that?

You put the grey water into the soakaway
and the **** and **** into the sewer, stupid.

Every house I know of (apart form old ones where it's all one pipe) have
to pipes, one goes into the rainwater drains and meets up with water
flowing off the road, and the other gets treated. Rain into the rivers,
grey and brown into the sewage treatment plant. All a soakaway would do
is to put less into the rainwater system which goes straight into a river
anyway.

As far as I know, our house doesn't put rainwater into the septic tank,
but pipes it into the same soakaway under the lawn that is used for the
outflow of treated sewage water from the septic tank.

You must have a huge lawn. I couldn't soak that much water away.

It must have done before the house was there.

The lawn is already full of rainwater that landed directly on it, you
can't add more to that.

Wrong, as always.
