Full Retention Separators

Full Retention Separators

As the name implies these separators treat the full flow that can be delivered by the drainage system - normally equivalent to the flow generated by a rainfall intensity of 65mm/hr.

On larger sites however, some short term flooding may be an acceptable means of limiting the flow rate and thus the size of full retention systems. Full retention separators are used where there is a risk of regular contamination with oil and a foreseeable risk of significant spillages e.g. vehicle maintenance areas and retail fuel forecourts.  All full retention separators are fitted with an automatic closure device (ACD) as standard.  Compulsory for all PPG3 compliant full retention separators, the ACD prevents accumulated pollutants flowing through the unit when the maximum storage level is achieved.

Areas for possible application:


• Sites with high risk of oil contamination 

Fuel storage depots 

Refueling facilities 

Petrol forecourts 

Vehicle maintenance areas/workshops
