Sewerage sludge odours
This is a by-product of the treatment of sewage at wastewater treatment works. Water is removed from the sludge and lime is added to produce sewage sludge cake. The Government policy is that the best environmental option is to dispose of sewage sludge on agricultural land.
The addition of lime reduces potential for odour, kills bacteria to a safe level and improves its suitability for spreading on agricultural land.
Any environmental problems caused by the storage of sewage sludge are regulated by the Environment Agency.
Odours caused during the spreading of sewage sludge can be investigated by our Environmental Protection team.
