Wastewater Charges

Standing Charge

The standing charge covers the fixed costs inherent to maintaining the wastewater network e.g. asset monitoring, staffing. The standing charge for wastewater is £36.24 (£35.20) per annum for every household/business, or £9.06 (£8.80) per quarter.

Variable Charge

The variable charge covers the costs directly related to the amount of flow generated by each property's individual discharge e.g. sewer lining, pumping station repairs. Metered customers will be charged on 90% of the water that comes in through the meter (as it is estimated that 90% of water goes to waste), at a rate of £0.70 (£0.68) per cubic metre.

Unmetered customers will be charged £0.20 (£0.19) for every unit of their property's TRP per quarter.
