For some agricultural, recreational, industrial and commercial uses where large amounts of water are not returned to the sewers, we may make a special allowance. Please contact us if you think you qualify.
Some commercial and industrial businesses produce wastewater which is also known as trade effluent. If this effluent is discharged to sewer you are required to apply for a trade effluent consent.

Trade effluent charges are calculated by using the Mogden formula.
C = R + V + Bv + Ot. B + St. S
Os Ss
Where:
| C = | Total Charge per cubic metre |
|---|---|
| R = | Reception and conveyance |
| V = | Volumetric treatment |
| Bv = | Volumetric charge for biological treatment |
| B = | Biological treatment charge |
| S = | Sludge treatment and disposal charge |
| Ot = | Chemical Oxygen Demand (settled COD) in mg/l |
| Os = | Regional weighted average COD = 345mg/l |
| St = | Total suspended solids (settled) in mg/l |
| Ss = | Regional weighted average suspended solids = 160mg/l |
Trade effluent charges for the period 1 April 2011 - 31 March 2012 are detailed in the table below:
| Pence per cubic metre | |
