Grease traps are employed by restaurants and hospitality businesses around the world to prevent fat, oils and other greasy substances (commonly referred to as FOGs) from entering and causing problems in the public sewer system. Local governments have made the installation of these interceptors a legal requirement for new establishments in order to better service the community. Any vacuum truck for sale today can provide further assistance by emptying and transporting the collected FOGs from the traps – a fact that is causing many businesses to invest in new trucks in order to expand their practices into grease hauling territory.

To intercept incoming FOGs on their way through the pipeline, the grease traps are installed somewhere between the pipe opening and the municipal sewer system, either on or outside the business property. The flow of greasy water is slowed down by the trapping mechanism, giving the liquid time to cool and the FOGs to coagulate, separating heavy solids that sink to the bottom of the septic tank from lighter substances, which float to the top. The remaining water passes through the trap into the sewers. Although more modern interceptors use microorganisms to break down the FOGs, allowing for less maintenance and smaller tanks to be used, the standard grease trap system in the US is the one described above. This technology requires the septic tanks to be cleared on a regular basis, ranging from every three months for big businesses to approximately once per year for smaller restaurants. This is where the need for vacuum trucks comes in.
For the purpose of cleaning and transporting FOGs, the most popular kind of vacuum truck for sale is one with a storage tank made from a light, versatile material, such as aluminum. Most businesses have several trucks with varying tank sizes, ranging from a few hundred gallons to several thousand gallons of loading capacity. It is important for the hauling company to confer with the business looking to empty their grease trap in order to perform the operation safely and thoroughly. Most local governments mandate a fine for mishandling and large spillage of FOGs, especially if they enter the sewer system. Before the vacuum truck is put to use, the tank should be emptied of the remaining water and have its walls cleaned using a power flush or pressure cleaner to ensure that all the grease is collected in one place. Once the grease is collected it can be extracted using the truck’s vacuum hose. Dense clusters can generally be removed using moderate suction, though stronger suction may be required to remove thinner layers.
With the grease trap thoroughly emptied, and the extracted FOGs stored safely in the septic tank of the truck, the restaurant proprietors can safely return to business as the waste is transported away. The regular nature of the procedure can provide hauling companies with many ongoing partnerships with restaurants and other businesses requiring the use of a FOG interceptor, and finding a suitable vacuum truck for sale is the first step for a growing company to expand into the hauling industry.
