We share around 10,000 customers with Thames Water in the Dartford and Godalming areas.
The following information is designed to help customers who receive water supply charges from Thames Water and wastewater charges from us.
You receive two bills because the water and wastewater services to your property are supplied by two different companies, Thames Water for water services and Southern Water for wastewater services.
Thames Water provides us with all the information we need to bill your metered wastewater charges.
Your water company will provide us with the meter details and we'll base our charges on the readings provided by them.
We can't meter the water that returns to the sewer for treatment because not all the water you use returns to the sewer. We've assessed the typical percentage return as 92.5% and so we bill based on a 'standard return to sewer' of this amount.
This means that for every 100 cubic metres supplied, we will bill for 92.5 cubic metres.
Please contact Thames Water.
If there are any problems with the meter that require a change to your bill, we'll be notified automatically.
If it's not possible to meter your water supply, you will switch from paying unmetered charges to paying assessed charges. These are calculated in various ways, for example the number of bedrooms in your home, or on single occupancy.
Where a wastewater-only customer is placed on an assessed measured charge for water services, we'll also switch that customer to assessed wastewater charges.
In this situation, we use Thames Water's method of assessment to calculate our wastewater charges.
Each independent water company has its own method of calculating assessed measured charges and therefore our wastewater charges reflect those differences.
If you think you are eligible for the single occupier charge please contact Thames Water, who'll inform us.
