About us.

Founded in 1984 by Mr. Roberto BERTILOTTI to meet the needs for modernizing the management of sanitation and drinking water networks in the departments of the Paris metropolitan area, PROLOG INGENIERIE, headquartered in Paris, is an independent consulting engineering firm, separate from any public service operators or industrial groups.

PROLOG INGENIERIE’s expertise and scope of action have since expanded significantly. Today, PROLOG INGENIERIE and its two subsidiaries, SIGT (Computer Systems for Technical Management) and SAGEE (Water and Environmental Planning and Management Company), rely on a team of around fifty professionals with extensive experience in the fields of water resources and environmental engineering : sanitation, drinking water, rivers, telemanagement, modeling, project management, measurement, and IT. They can operate at a level tailored to specific needs, as advisors, experts, or project managers.

Our offices in Bordeaux and Lyon ensure a proximity and responsiveness to our clients across France.

With over 40 years of activity, our group has established its identity and built a culture of engineering highly valued by our clients.

Our commercial and technical teams are at your disposal to provide detailed information about our expertise and services, as well as to introduce the dedicated team members who make PROLOG INGENIERIE a recognized leader in water engineering.
