HOME AGENCY CERTIFICATIONS SECTORS PORTFOLIO WORK WITH US CONTACTS SEWERS Sewers SECTORS OF INTERVENTION In the drainage of sewage water, the company has gained extensive experience in the execution of white rainwater, black and mixed urban sewers by laying pipes of all types and adoptable materials, from stoneware to concrete, from cast iron to GRP (both at wound and centrifuged filament), connected with both cup, sleeve, and welded joints. The installation of the gravity sections in the trenches is carried out not only relying on the skills of its technicians and workers but, given the fundamental respect of the project slopes, during the installation phase the levels are fixed with the aid of laser levels of the latest generation and continuously checked. Even in the sewerage sector, the company is able to carry out the laying of pipelines with NO-DIG technologies, without excavation, with the aid of Controlled Horizontal Drilling, as well as with pipe pusher and / or microtunneling for crossing under the track of roads, railway networks and waterways. The tightness of the laid pipes is verified both with water and air, while both the inspection artifacts and the recurring works of art (bedrooms, spillways, lifting stations), the company is able to make them both prefabricated and in concrete reinforced cast on site, with any type of internal coating (tiles, epoxy resins or thermoplastic material such as PP / PRFW / HDPE, etc.). Also in the sewerage sector, SIA srl has built both prefabricated and on-site lifting stations, complete with all electromechanical equipment: the installation deserves particular mention in this regard, as part of the construction of the new sewer in the municipality of Torre Annunziata (Client GORISpa), of the prefabricated GRP station among the largest that the world's leading manufacturer of centrifuged fiberglass pipes has ever supplied in Italy.
