Grease Trap Services

OdorCure offers a wide range of specialised grease and fat trap services from the supply and installation of new grease traps to services such as, Automated Dosing Systems, Scheduled daily, weekly or monthly maintenance programs and once-off deep cleans of grease traps, sewer sumps and septic systems.

When maintained properly, a grease trap prevent your kitchen grease and food waste materials from entering the city sewer system.  Grease is a leading cause of sanitary sewer overflows, since it clogs sanitary sewer lines and ultimately causes line blockages. The result is all too frequent discharges of untreated wastewater into streets, homes and commercial enterprises. Ultimately these problematic waste streams enter our local waterways, where they cause further cleanup costs and restrict recreation, tourism and commerce. Your traps must be regularly emptied and periodically cleaned to prevent costly and dirty back-ups or over-flows.


At OdorCure (Pty) Ltd our mission is two fold: protect your business and protect the environment.

We protect your business by collecting and properly disposing of your non-hazardous liquid waste streams. We pump non-hazardous liquid waste out of your collection tanks (traps or interceptors,as well as holding tanks or containment areas for wastewaters), preventing overflows of waste and keeping your facilities safe from contamination. We also keep you in full compliance with strict waste removal and disposal regulations, shielding you from government fines.

Protecting your business also helps us, and you, protect our precious environment. The environment is everywhere — where we live and work, where livestock feed, where crops grow, where fish swim, and where our kids play.


What does it take to protect your business and the environment too?

  • A fleet of custom built Vacuum Tankers to ensure consistent, timely pumping and cleaning of your waste traps.
  • Our direct supervision and control to ensure proper disposal of waste at every step.
  • A meticulous and comprehensive process for collecting and disposing of waste that complies not only with government regulations but also with environmentally responsible principles.
  • A team of waste management experts, from the operators of our Vacuum Tankers to our legal compliance team who follow our process to the letter.

How improper waste management harms our environment.

Here are just a few examples of the potential for harm to our environment:

  • Improper collection and disposal of fats, oils and grease can lead to these substances getting into our municipal sanitary sewer system. This can lead to sewer overflows that can contaminate business sites, homes and the outdoors too. Post-spill clean up and maintenance is expensive.
  • Many businesses don’t regularly inspect and clean out their storm water retention systems. These systems become full and then overflow, dumping not only fats, oils and grease, but also metals, chemicals and other potentially dangerous pollutants directly into our streams, rivers and oceans. Local governments are starting to enact regulations to prevent this and businesses will be required to comply.
  • Rainwater mixed with even a trace amount of oil or industrial materials is a threat to agriculture, wildlife and our own water supplies.

Proper waste management is the key to preventing these and other threats to the environment we live in.


Most importantly, it takes a company-wide commitment to keeping our environment 100% free of pollution. Everyone who works at OdorCure shares this passion — for the good of you, and for the good of our community. This commitment is your best assurance that your waste is being handled in the most responsible manner.


Grease traps and interceptors

What are they?

Grease traps are used primarily in mechanical workshops and food industry kitchens. Their function is always the same: to remove solids and fats, oils and greases (FOG) from liquid effluent streams.

A typical grease trap has three parts:

  1. A solid particle interceptor – also known as a sludge catcher;
  2. A grease/fat interceptor – called the ‘stilling tank’ where FOG in dirty water is prevented from rising to the surface; and
  3. A small sampling chamber – where the improved quality of the cleaned effluent can be observed.

Grease traps are rated on their flow performance. For example:

  • Small users such as households and sandwich bars will use traps rated at 1.5lt per second;
  • Medium-sized restaurants and food production lines often use traps rated at 4.5lt per second; and
  • Food courts, dairies, cheese factories, etc. will use a trap rated at 11lt per second.

How a grease trap work

The aim of a grease trap is to improve the discharge quality of the effluent prior to it entering the municipal sewer, and to allow an operator to remove solids and grease from the effluent stream with ease.

Well designed grease traps usually have three chambers. The first chamber is equipped with perforated solids retention baskets into which the inflowing effluent arrives. The second chamber, between two baffles, slows the liquid permitting the oils to float to the surface (since oil floats on water) where microorganisms – both latent and added – degrade the floating scum from the underside, improving the quality of the effluent. When there is excessive fat in the effluent a scum will form and is liable to steadily thicken with the increased daily volumes. This fat scum should be removed carefully to avoid dripping and discarded in an approved fashion (BIO-SYSTEMS can provide an established protocol for this task). The third chamber is narrow and allows for visual inspection and sampling.

In many cases grease traps receive effluent from both floor drains and sinks. Dirty water flows through the particle interceptor (perforated sieve baskets) where small solids such as metal swarf, scraps of meat and vegetable solids are caught in the chamber baskets – these should be emptied into disposal bags twice a day before the rubbish putrefies and becomes unpleasant to handle. The grease interceptor trap should be situated sufficiently far away (down-line) from the under sink particle interceptor to allow the temperature of the dirty water to drop to below 40oC, preventing the biomass of bacteria in the stilling tank from being damaged.

Common grease trap problems

Oil overload is a frequent problem plaguing industrial grease traps. Modern fuels, lubricants and catering oils are highly complex compounds and pose even more of a problem because they are difficult to degrade and take a long time to break down. The result? Congested, slimy drain pipes and sulphurous, foul odours. This is also true of effluent in the food and catering industry where modern ‘trans fats’ often accumulate and cause blockages unless dealt with correctly and timeously.
