The Sostelia Group

CID has specialised in the design, construction and operation of wastewater treatment and purification plants since 1979. Since 2024, our company has been part of Sostelia, a Italian reference group for industrial water treatment. The Group consists of eight highly specialised Italian companies, with which it responds to any water purification and treatment need.

The purifiers built over time, the decades of experience of the companies that make up the Group, and their widespread presence across Italy allow Sostelia to meet all requests for the development of innovative and efficient industrial water treatment plants. The Group’s products promote sustainability, water recovery and the proper disposal of liquid waste from companies and public bodies.
