Does trade effluent control apply to my business?

Trade effluent control applies to all businesses that discharge wastewater to a public sewer, from independent traders to large multinational companies. In the UK even small discharges of a few litres a day require legal consent from the water and sewerage company.

Trade effluent is typically wastewater or other waste liquids not considered to be domestic sewage or uncontaminated rainwater run-off. Consent conditions include volume, flow rate, pH, temperature, suspended solids, chemical oxygen demand, fat-oil-and-grease (FOG) and metals.

Facilities involved in the production of food and drink, chemicals, metals, textiles, paper and sites recycling solid waste are all likely to require a water company consent to discharge.

Why do I need to test my facility’s effluent?

UK water companies calculate trade effluent charges based on a number of variables, including volume, type and the degree of contamination, this is known as the Mogden formula. By knowing the parameters of your effluent, you can make better decisions on how to optimise your liquid waste processes and minimise costs.
