# Why are billed amounts for clean and waste water the same?

Volume used is 19m3, so why is 19.00 charged for both clean and waste? Shouldn't it be a combination of two values totalling 19m3?

that is correct, its all based on clean water going through your meter , there is no meter on your sewage

So this assumes all clean water I use eventually goes down the drain....

My thinking is that I can fill a bucket with xm3 of clean water, and water the plants with it. That volume never goes down the drain, yet I'm being billed for it?

You've got a point.
Yorkshire Water charge for waste water at 95% of the metered volume.

In the last couple of years I've been with Southern Water and South East Water and both charged at 92.5% for waste water.

Just an aside but in two months you have used almost 2 tonnes of water!

Always been so, so if you hose the garden it doesn't go down the drain.

Assuming two people, isn’t that roughly on target for the national average? (55 m3 / year)

Apparently the 5% or 7.5% reduction in charges to allow for evaporation, garden watering etc is done by reducing the per cubic metre sewerage charge.
E.G. take a customer being supplied with, say, 100 cubic metres(m3) of water from the mains, and the water company allowing 5% for evaporation etc. The full charge for sewerage is £2 per m3.
They can either.
1. Charge £2 on 95m3 = £190 -
or
2. Charge £1.90 on 100m3 = £190

In the early days of metering method 1 was used on bills, but for years now method 2 has been used by my water company.
So the OP's charge of £0.8672 per m3 is after it has been reduced by 5% or 7.5% (or whatever figure Thames Water use.

Or 19 tonnes, to be precise!

Ah yes, that's what I meant.
