Conder CNS6S/11 Full Retention Oil Separator - up to 333m2
£983.00
Direct Drainage Reviews

The Conder range of Full Retention Separators are used to fully treat the full flow that can be delivered by a drainage system, which is normally equivalent to the flow generated by a rainfall intensity of 65mm/hr. Full Retention Separators are used when there is a risk of regular contamination with oil and a foreseeable risk of significant spillages, such as vehicle maintenance areas and retail fuel forecourts.

All full retention separators have an automatic closure device (ACD) fitted as standard. Compulsory for all PPG3 compliant full retention separators, the ACD prevents accumulated pollutants flowing through the unit when maximum storage level is reached.

Process and Performance


Contaminated water enters the separator, the liquid is retained for a sufficient period to ensure that the lighter than water pollutants, such as oils and petrol, separate and rise to the surface of the water and are retained within the separator. Decontaminated water is discharged. Retained oil must be emptied from the separator once the level of oil is reached, or the oil level alarm is activated and the closure device operated.

Alarm Options


Environment Agency PPG3 Guidelines stipulate that all separators must be fitted with a robust system to provide an audible and visual alarm if the oil level becomes too high. We strongly recommend that you purchase the High Oil Level Alarm alongside this item, and it will be delivered with the separator ready to wire in.

Alarm options include the Darcy indoor oil alarmDarcy outdoor oil alarm, Darcy battery-powered GSM alarm or Darcy solar alarm
