Operations like car washes and the like quickly generate large amounts of oil and grease debris. If allowed to accumulate, sand, mud, and other solids will rapidly fill the settling tank until the inlet and outlet ports clog and the water backs up. Also, oil floating on top can likewise collect and force their way down until plugging the ports. Removing these wastes requires both specialized equipment and the legal permits to properly dispose of the materials in a designated landfill.
Water backing up from a poorly maintained trap is an obvious problem. A less obvious hazard from infrequent trap cleaning is the build-up of gases. Harmful chemicals like aromatic hydrocarbons or benzene are often contained in the oily residue washed off of vehicles. Many traps are designed to let airborne waste safely vent, but when oils amass at the top, they can block the vents. Some gases can be flammable. Other gases can possibly be driven back through the water line with enough pressure. In some cases, certain gases like hydrogen sulfide will form sulfuric acid that can corrode the trap itself, requiring expensive replacement. Clearly, keeping traps regularly cleaned is a big money saver. Polarized Water Solutions has the tools to do the job thoroughly.
