Sometimes, there’s a difference between the amount of water you use and the amount of wastewater that returns to our sewer system.
We’ve built this into our charges already, which is why we don’t charge you for 10% of the wastewater you use.
If you can prove that more than 10% of the water you use doesn’t return to our sewers for treatment, you can apply to reduce the cost of your bill even further.
If you apply to reduce the cost of your wastewater bill, we’ll get back to you within six working days. If you have more than one property, please use a new form each time you apply.
