SEPARATORS
A Range of Fuel/Oil Separators
Surface water drains normally discharge to a watercourse or indirectly into underground
waters (groundwater) via a soakaway. Contamination of surface water by oil, chemicals or
suspended solids can cause these discharges to have a serious impact on the receivingwater.
Where run-off is draining from relatively low risk areas such as car-parks and non-operational areas, a source control
approach, such as permeable surfaces or infiltration trenches, may offer a suitable means of treatment, removing the
need for a separator. Oil separators are installed on surface water drainage systems to protect receiving waters from
pollution by oil, which may be present due to minor leaks from vehicles and plant, from accidental spillage.
Effluent from industrial processes and vehicle washing should normally be discharged to the foul sewer
(subject to the approval of the sewerage undertaker) for further treatment at a municipal treatment works.
Full retention
Separators
Full retention separators treat the
full flow that can be delivered by the
drainage system, which is normally
equivalent to the flow generated by
a rainfall intensity of 65mm/hr.
On large sites, some short term
flooding may be an acceptable means
of limiting the flow rate and hence the
size of full retention systems.
