The Australian Standard, AS 4494: Discharge of commercial and industrial liquid waste to sewer, states that the receiving water authority has the power to regulate the use and design of grease traps in their jurisdiction.
Local water authorities have specific regional requirements. They recommend the size of the grease trap, the total volume of wastewater to be held in retention and approve the installation of the grease trap.
To ensure the longevity of the installation, water authorities usually provide a conservative estimate for the volume of wastewater to be treated.

ACO’s range of grease traps are designed and manufactured in Europe in accordance with EN 1825: Grease traps. ACO Australia believes that this is the most appropriate internationally recognised performance based standard.
EN 1825 specifies a wastewater quality requirement of a maximum 25mg/L concentration of hydrocarbons. This ensures that a grease trap can effectively separate Fats, Oils and Grease (FOG) from wastewater, before discharging it into the sewer system.
