What is the Mogden formula?

The Mogden formula seeks to link charges for discharging trade effluent to the public sewer to the costs imposed by customers, i.e. by paying according to the volume and strength of trade effluent discharged. The formula was agreed between the water industry and the Confederation of British Industry.
