Vacuum tanks perform a variety of duties. On drilling and hydro-excavating jobs, a vacuum tank can remove sludge, water, and muddy debris from a job site both from the surface and underground. For the cleaning of septic tank systems and sewers, the powerful suction of a vacuum tank can easily handle removing build-up and sludge leaving the sewer more efficient and resistant to flooding. Vacuum tanks are often used in environmental spills and clean-up where because of their unique construction, they have the ability to suction up, store, and remove hazardous waste. Vacuum tanks are versatile because they can be transported on a flatbed or trailer and taken directly to the site where they are needed.
