Oil separators are designed to prevent oil and other hydrocarbons from entering the drainage system. They
separate oil from water, and safely retain the oil until it is removed.
Oil cannot be treated easily and will therefore cause severe pollution if allowed to enter mains sewers or
drainage fields. Statutory controls enforce strict regulations on the discharge of such pollutants.
Separators should be used in such applications as petrol stations, industrial yards and garages; or virtually any
site where a risk of oil contamination exists.
Discharge requirements for oil separators may vary in different areas of the country and it is therefore
essential to consult the appropriate environmental controlling authority prior to specifying an oil separator. If
the discharge is to a public sewer then local Building Control, the Water Authorities and water companies
should also be contacted.
