Clean rainfall arriving on the catchment when the platform in not is use is directed to stormwatervia the Oil/Water Separation System
The risk of “Flammable” fuel spillage becomes apparent during fuel transfers
Stormwater discharge to the environment requires @ <5ppm hydrocarbon content = Current Industry Best Practice
Installation of a fuel spill retention and alarm system is required to manage this environmental risk
The accumulated minor spill retention capacity needs to be approx. 600 litres
The system requires the ability to isolate the stormwater discharge in the event of a major spill
The system requires an accumulated spill detection alarm to notify when the collection tanks requires evacuation of the floating layer of hydrocarbons
The Alarm system requires an Intrinsically Safe barrier and sensing module as the air space above the water level in the collection tank is classed as a zone 1 explosive hazard
Typical stormwater Rainfall IFD requires calculation, but will on most cases be < 20.0 L/sec
Collection pits or gratings are installed in the catchment pavement, with (fire rated) discharge pipework directed to the collection, treatment and isolation tank installed at ground level
Conduit materials and signal cable seals to be appropriate for Flammable Fuel applications
Product Ref- Option 1
LH-ESK-20-FL-LA – Refer drawing – Pre-cast concrete tank installed at ground level with 200mm inlet and outlet stubs, oil separation medium, spill retention capacity, spill isolation valve, spill sensing probe and remote alarm signaling capability
Tank Access Cover is located at Finished Surface level
Alarms to be local, with the option also available to communicate to a remote BMS
Note
These projects require input and design assistance available from our engineering department
