For almost 30 years, we have mastered the polyethylene extrusion blow moulding process, an industrial technique that enables the manufacture of large capacity hollow vessels, thanks to our machine population which is one of the biggest. As a specialist in the design and manufacture of vats and storage tanks, domestic fuel tanks, self-contained sewage systems and related products (septic tanks etc.) and water treatment equipment, Sotralentz is a member of the IFAA ('Industriels Français l´Assainissement Autonome' – French manufacturers of self-contained sewage systems).
