Regular servicing of your grease trap helps to protect our environment
Clarence Valley Septics is a liquid waste company that offers the collection, transportation and processing of liquid wastes and industrial services from domestic, commercial and industrial activities in the Clarence Valley and Coffs Coast areas.
A grease trap is designed to trap insoluble and difficult to breakdown greases and fats before they enter the sewer system. Traps are pumped with vacuum tankers and the contents transported to our liquid food waste processing facility. Here, a state-of-the art system removes the greases and fats forming a biosolid whilst the liquid is transformed into a reuse quality.

The proliferation of restaurants and fast food establishments over the past 30 – 40 years created a situation where large quantities of cooking fat, oil and grease were being discharged to the sewer. These materials were in turn blocking up the sewer pipe lines and creating problems with sewage treatment.
Commercial size grease traps were installed to trap these wastes (on the site of the generating premises) before they extend to the sewage system. Council regulations were then introduced to ensure that they were pumped out on a regular basis.
Further regulations stipulate that these wastes must be separately treated before they re-enter the waste stream.
The treatment of these wastes commences with filtration and screening before pH adjustment and a sludge/water separation via a dissolved air floatation process. The solids/sludge (grease oil and fat) from this process is dewatered and formed into a semi-solid cake before landfilling while the water component is aerated until the biochemical ozygen demand (BOD) is reduced to a council sewer acceptable level.
This process is closely monitored by council and the E.P.A.
