The municipalities are also entrusted with the task of keeping the sewers of urban centers free and clean. Drains, wells, pipes and drains, in fact, are essential elements for disposing of white water and black water, and require frequent washing and unblocking operations.
Procedures that are effectively carried out with the so-called sewer cleaning units, based on a jet of high pressure water (produced once again by a piston pump) called hydrojet which pushes a particular nozzle along the pipeline to be unblocked, while cleaning the surfaces of the pipe itself.
In addition to roads, municipalities also deal with the maintenance of public buildings, such as offices, schools and administrative structures which, like any other private property, have pipes for toilets and, in some particular cases, kitchens and refectories.
Unfortunately, soap, food residues, hair and other debris also easily block the pipes of public buildings, just as foliage and soil block external gutters. To unblock them, we intervene by applying the power of canal-jet machines equipped with piston pumps: sewer cleaning equipment that uses a jet of high-pressure water, delivered by a nozzle specially designed for cleaning pipes. High pressure water unclog and cleans duct surfaces.
