Waste water reductions
There may be reductions available from the sewerage companies for waste water (the water from sinks, toilets, baths etc. in your property) or Surface Water (the water that goes into drainage from rain or snow falling on your property). This reduction is given by your waste water company who will advise us to apply the reduction to their part of the bill. We cannot change your bill until we hear from them.
If none of your waste water or surface water goes into the main drainage system, i.e. you have a septic tank or your own waste management system, the waste water companies will not normally charge you. The reduction is at the discretion of the waste water companies, and you should contact them first using the details above. They may ask you to confirm current charges, which are on your bill, or we can help with this. Please click on Contact us at the top of the page.
Surface water abatement
There are some circumstances where you may not need to pay the full amount of your sewerage charges.
If the rain water falling on your property does not go into the main drainage system, if it goes into a soak-away for example, you could apply for a surface water abatement. Please contact your waste water company.

Thames Water - Waste water abatement
If there is a difference between the amount of water you use and the amount of effluent you discharge into the sewer system, for example water used to irrigate plants. Thames Water may grant a wastewater abatement allowance, which takes these differences into consideration. Customers will need to prove that over ten per cent of their metered water usage is not returned to the sewer for treatment and you should contact them on the details above.
Anglian Water - Waste water abatement
For domestic customers, Anglian Water already allow 10% for water that does not go into the main drainage system, for metered customers, this means that usage shown by your meter readings will be used in full for water charges but only 90% of the usage will be used for waste charges.
If you are a business customer or can demonstrate that less than 90% of your water is returned to the main sewer, you should contact Anglian Water directly to discuss whether a higher allowance is appropriate for you.
