You could reduce your bill if your surface water doesn't drain to the public sewer
First things first – what is 'surface water'? Well, we describe it as water that falls as rain, is collected by drains and gullies on your property, before being removed by us via a public sewer.
And you could knock money off your bill if:
- all the rainwater or groundwater from your home including your roof (or shared roof), garden, drive, patio and yard, drains directly to the ground or via a soakaway (a means of draining away water through the ground) at both the front and/or rear of your property
- all the rainwater or groundwater from your home, garden and hard standing areas (e.g. drive, patio or yard) drains directly into a watercourse, brook or stream and does not enter the public sewer
- you pay a third party (e.g. British Waterways) to dispose of your surface water
We've included a diagram to illustrate a property that may be entitled to a reduction.
You are not entitled to a reduction if:
- any proportion of your surface water drains to the public sewer
- only part of your surface water goes to a soakaway, with some surface water still draining to the public sewer
- you have re-directed your roof drainage into water butts
- you drain to a watercourse, brook or stream via the public sewer
We've included a diagram to illustrate a property that is not entitled to a reduction.
How to apply for a reduction in your water bill
- If you believe that none of your surface water drains to a public sewer, please download our application form and answer all the questions. You will also need to draw a diagram showing your home, garden and hard standing areas, and indicate where you think your surface water drains to. This will help us if we need to visit your home to check whether or not your surface water drains to the public sewer.
