Petrol interceptor

A petrol interceptor is a trap used to filter out hydrocarbon pollutants from rainwater runoff.

It is typically used in road construction and on Petrol Station forecourts to prevent fuel contamination of streams carrying away the runoff.

Petrol interceptors work on the premise that some hydrocarbons such as petroleum and diesel float on the top of water.

Typically petrol interceptors have 3 separate tanks each connected with a dip pipe.

When the water leaves the third tank via the outlet pipe it should be contaminant free.
