If you have received consent to discharge trade effluent, you will receive a trade effluent bill from us.
These charges are reviewed annually to ensure they reflect the cost of the services we provide which include reception, conveyance and treatment of effluent.
The charge you pay is determined by:
The stronger the trade effluent you are discharging to the public sewer, the higher the unit charge.
The table below gives an indication of the typical unit charges for different types of customer.
The unit charge is made up from a fixed volume charge and variable strength charge, related to the average suspended solids and settled chemical oxygen demand (COD) content. COD is a measure of the organic content of the trade effluent. Examples of the how the unit charge is made up for different types of customer is shown below.
