Full Retention Range
Application
Full retention separators are used in areas where there is a risk
of regular contamination of surface water run-off oil and/or a risk
of larger spills. These areas include:
• Fuel Depots
• Vehicle Workshops
As contaminated water passes through the separator, it is
retained long enough to allow pollutants to accumulate on the
surface. Carlow Precast full retention separators are single
chamber vessels, resulting in the minimum of turbulence, while
maximising retention time. The pollutants are retained within the
separator, allowing treated water to discharge.
Each full retention separator features the following:
• Oil Storage Capacity
• Silt Storage Capacity
• Coalescer (Class 1 only)
• Automatic Shut-off Valve
Maintenance
The hydrocarbon pollutants and silt that build up within the
separator, should be removed periodically to ensure that
maximum effectiveness of the unit is maintained. In the event of
a major spillage, the separator should be emptied immediately.
Materials
Carlow Precast full retention separators are manufactured from
70N concrete with steel fibre reinforcement at 40kg/m3 . Larger
units contain conventional steel reinforcement as well as steel
fibre.
Installation
The unit should be installed on a level bed of sand, gravel or
broken stone. The base of the excavation should be level and
free from projecting hard points such as rocks or boulders.
The separator is lifted into position by our truck-mounted crane,
assuming there is suitable access for our delivery vehicle.
Backfilling is commenced as soon as possible after placement of

the separators. In most installations, it is not necessary to backfill
around the separator with concrete.
Advantages
- Ease of installation
- Speed of installation
- Reduced civil costs - no expensive concrete backfill
- Durability and robustness
- No extra reinforcement in heavily trafficked areas
Accessories
Access covers to suit all loadings are available on request.

Oil level alarms can be fitted to indicate when the separator
requires emptying. They are mounted remotely from the unit and
are available with an audible or visual alarm. Off-site monitoring
is also available from our technical department.
