Surface water drainage

Surface water is the water that falls on your roof or the hard paved surfaces of your property such as a driveway or patio.

The cost of removing and treating surface water is included in the sewerage charges you pay.

You may be entitled to an allowance if you receive sewerage services from us and the majority of the surface water drainage from your property does not return to our sewer.
