You are correct, there is a tiny reduction. However the sewage charges
are still more than the fresh water charges. I appreciate it all costs
money, but I would have thought it would cost more to make water
potable than treat sewage?

Watch out for any charges they may impose to read the
second meter especially as the intention is to move towards roadside,
remote metering using readers in vans.

Yes, I have asked them about that too. The idea is to save more, not
get charged more.
