A sewer suction machine, also known as a sewer cleaning truck or vacuum truck, is a specialized vehicle used for cleaning and maintaining sewage and drainage systems. These machines are equipped with a powerful vacuum system that can remove debris, sludge, and other obstructions from sewers, storm drains, and wastewater pipes. Sewer suction machines play a crucial role in the maintenance of urban infrastructure and wastewater management.

Sewer suction machines are essential for regular maintenance, cleaning, and repair of sewage and drainage systems, preventing blockages, backups, and ensuring the efficient flow of wastewater. They are commonly used by municipal authorities, utility companies, and contractors responsible for sewer and stormwater management.
