Joint Southern Water customers

Last reviewed:
If Southern Water provides your clean water and we take away your wastewater, you should be aware that Southern Water is installing water meters for all its customers.

How is my wastewater calculated?

Your wastewater bill will be based on 90% of the water you use, as that is what we take away. So the less water you use means the less water we take away and the lower your wastewater bill will be.

We won’t change the way your wastewater bill is calculated for two years after Southern Water has fitted your meter, unless you ask us to. You’ll continue to receive your bill from us as normal.

Over that period we will write to you, showing what your wastewater bill would be if you were charged using your meter. This will happen around three months after the activation of your meter by Southern Water, then every six months after that.

This will give you an idea what your wastewater bill is likely to be when we do start charging you using your meter.
