UK Trade Effluent Savings Calculator

Use our calculator to find out how much the Hydro MicroScreen™ could help you save on your trade effluent charges.

Industrial or process wastewater sent to a sewer attracts a "Trade Effluent Charge”. This charge varies depending on effluent volume and quality: the more there is, and the ‘dirtier’ it is, the greater the cost. Anyone who uses water in their production process is paying to discharge their effluent into the sewer...but if you can improve the cleanliness of your effluent then you can reduce your discharge costs.

Our separation systems can help you to discharge cleaner effluent, cutting your trade effluent charge. Try our calculator to find out how much you could save.

Select your water company area, input your flow level and your TSS and COD levels, or select an industry to get average TSS and COD figures. Our calculator will work out how much this would cost you in trade effluent charges, and will show you how much you could save by using a Hydro MicroScreen™ system to treat your process water.

About the Mogden formula and Trade Effluent

What is Trade Effluent?

Trade effluent is any waste water, other than domestic water or surface water, which is discharged from a commercial or industrial process or activity.

How are trade effluent bills calculated?

Trade effluent charges are calculated using the Mogden formula, and are agreed by the water industry and the Confederation of British Industries. Monitoring and sampling costs are included within the overall charges calculated.

How are businesses charged for trade effluent?

Charges are based on much effluent is discharged, and what level of pollutants (TSS - Total Suspended Solids, and COD - Chemical Oxygen Demand) are present in it. Charges are payable in addition to adjusted sewerage charges.

What is trade effluent consent?

A trade effluent consent is a legal document issued by the company responsible for sewage and the upkeep of the public sewer. This document contains a number of conditions and places certain limitations on the quality and quantity of the discharge.

What does a trade effluent consent contain?

In order to prevent issues in the sewer network, at water treatment plants or in the environment, a trade effluent consent is likely to prescribe limits on the maximum daily volume discharged, the maximum discharge rate, and the concentration of TSS, COD and other pollutants. There may also be limits on substances that produce flammable, harmful or toxic vapours, and there may be limits on the temperature of the effluent discharged.

How can a business demonstrate compliance with a trade effluent consent?

Standard statements and reports are available from water companies. Monitoring businesses may also be able to provide assistance.

How can I save money on trade effluent?

The amount a business is charged for trade effluent depends on both the quantity of effluent produced and the level of pollutants that it contains. Reducing the volume of effluent and improving its quality will ensure that your business remains compliant with consents, and cuts charges. Accurate monitoring (including meter readings) is critical to reporting, and recycling or reusing effluent water will reduce discharge volumes.
