********. It means a sewage treatment plant.
big snip

AIUI, dishwaters incorporate a salt-dispensing (and tablets boast of
containg salt) water softener; so are such devices 'caught' by these
regulations?
They *should* be, based on he legislation. Possibly there's an
internal check valve, but I've never heard of one.


Hmm, "interesting ", what?


How does the 'salty' discharge of a dishwasher used two times a
day by a large family compare against a water-softener used by a
two-person
household?
Less because the amount of water being softened is less.

I've become interested in the thread because I'm contemplating installing a
water softener [this fiscal year]. AIUI, the 'Kinetico' dual cylinder model
type only purges a
cylinder with about 16 litres of water. Intuitively the dishwater would
discharge more than this amount each time it was used. How much water is
softened on each dishwasher operation? I purchase about 1Kg of (dishwater)
salt per month ... how does this compare with the salt consumption of a
softener?

I get through 25kg a month - about £6.50.

Thats on a largeish house that squanders water in a very hard water area.

However I buy about 8 bars of soap a year, and probably as little shampoo...
