Open Water Charges


There are three types of measured water and sewerage charges.

The standard measured tariff where a measured supply of water is made available subject to our standard terms and conditions of metered water. The sewerage charges are usually calculated on the assumption that 95% of the water consumption recorded by the meter is discharged to the sewer. If you believe that consistently less than 95% of the recorded water supplied is discharged to the sewer please download the form below, complete it and return it to us at P.O. Box 690, Cardiff, CF3 5WL.

Where it is not reasonably practicable to fit a meter, or it is unreasonably expensive to fit one, then we may charge on an assessed measured basis.

Customers may choose our industrial tariff when a large volume of water is used at a single site and/or the discharge of sewage is 100 Ml or more per annum from a single site. If you think you may benefit from this tariff please download the form below, complete it, and return it to us at P.O. Box 690, Cardiff, CF3 5WL.

For traders who have been permitted to discharge trade effluent directly or indirectly to a public sewer, they will be charged on our trade effluent tariff. This will either be on our standard tariff, or where the volume of effluent discharged from a single site is 100 Ml or more, then you may choose the industrial tariff.
