Surface water drainage
You are charged for surface water drainage. Different sewerage companies charge for this in different ways. If none of your surface water drains into the public sewers then you may be entitled to a rebate.
Your water company may charge for surface water drainage based on site area. If this is the case, then if more than 10% of your site area does not drain into the public sewers your company should give you a partial rebate. Typically,
- grassed areas
- gravelled areas
- areas that drain into a soakaway or
- areas that drain into a sustainable urban drainage system (SUDS)
qualify as not draining into the public sewers. Separate areas cannot be aggregated to make up the 10%.
Foul sewage
If you are a metered customer, your charges for foul sewage are based on your water usage. Find out more about cutting your water usage.
