Facts about Fat, Oil & Grease
Fat does not just cause problems in local drainage systems - it causes major issues for sewer networks.
The reduced capacity of the network caused by FOG accumulations can lead to surcharges where sewers are forced to 'overflow' into rivers, streams and beaches. Many major utilities have set up task-forces to address the problem and are adopting a 'polluter' pays principle.
