A consent is a legal document issued under the regulations within the Water Industry Act 1991. It is issued to the owner or occupier of a commercial or industrial property.
It allows the discharge of trade effluent into the public sewer under enforceable conditions which control the volume and quality of the discharge.
There are three types of consent:
You can apply for all three types of consents on the retailer portal on the G02 forms. You can find more information about each types of consent below.
|Condition||Why do we control it?|
|Volume and flow rate||Controlled to protect our sewers and wastewater treatment works from flooding, as well as protecting treatment processes from becoming overloaded.|
|pH (measure of acidity/alkalinity)||Extremes of pH can lead to an unsafe working environment, affect wastewater treatment processes and damage equipment or sewers.|
|Temperature||Temperature can increase odour in sewers as well as creating a dangerous working environment.|
|Suspended solids||The amount of particulates in a discharge and is controlled to prevent settlement and blockages in our sewers.|
|Chemicals Oxygen Demand (COD)||COD is the measure of oxygen consumption from the decomposition of organic matter. It's controlled to protect our biological wastewater treatment processes.|
|Fat, oil and grease (FOG)||FOG can cause blockages in our sewers and pumping stations which can lead to flooding or odours. It's also controlled to protect our wastewater treatment processes.|
|Ammonia||Ammonia can cause toxicity in watercourses and is removed in the wastewater treatment process. It may produce an unsafe environment in the sewer.|
|Sulphate||Sulphate can cause corrosion of concrete structures and produce odours.|
|Metals||Metals are controlled to protect agricultural land and the environment where treated sludge is spread.|
Some substances are classed as hazardous and must be reported to the Environment Agency prior to a consent being awarded.
Breach of any consent condition is a criminal offence and may result in prosecution.
