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.|
|Chemical 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.
