SeparatorsPlus is now part of Acumen

Separators and Sewage Plant

Acumen’s exclusive separator range includes Full Retention Separators, which are utilised for treating the full flow that can be delivered by the drainage system, normally equivalent to rainfall intensity of 65 mm/hour.

Our Bypass separators fully treat all flows generated by rainfall rates of up to 6.5 mm/hour (99% of all rainfall events). Flows above this rate can bypass the separator.

Our Forecourt separators provide a full retention separator specified to retain on site the maximum spillage likely to occur at a petrol filling station. A separator with an oil storage capacity of 7600 litres is usually required.

Whether you require assistance with design, build, supply or installation, Acumen can support your requirements, along with service and maintenance of the waste water treatment and monitoring equipment we provide.
