What IGRETEC does
IGRETEC (Intercommunale pour la Gestion et la Réalisation d'Etudes Techniques et Economiques) is a public inter-municipal engineering and territorial development cooperative headquartered in Charleroi, Belgium, serving Walloon municipalities, public institutions, and enterprises across Wallonia and Brussels. Formally created in 1985 through the merger of IEGSP (1946) and ADEC (1964), with intercommunal cooperation roots dating to 1937, the company operates as an "intercommunale pure" under the Code wallon de la démocratie locale et de la décentralisation, owned by its associated communes. The company mobilizes 400+ specialists across 30 complementary technical trades and has completed 1,200+ public infrastructure projects.
The company's core product is an integrated service platform combining a multidisciplinary engineering bureau (architecture, urban planning, energy, environmental studies, special techniques, structural stability) with project ownership services (assistance à maîtrise d'ouvrage, maîtrise d'ouvrage déléguée, construction surveillance), territorial development agency functions, water and energy utility operations, and citizen participation services. Technology assets include Geisica, a proprietary in-house software, an energy purchasing central aggregating 300+ public members for collective gas and electricity procurement, and CENEO, a subsidiary developing renewable energy projects (wind, photovoltaic, biomethanization, aquathermy). The company also operates 44 sewage treatment stations (40 EMAS-registered) and manages industrial site reconversion through Soresic (51%-owned with Wallonie Entreprendre).
IGRETEC generates revenue through fees from municipal engineering studies and construction supervision; managed services for water treatment and drainage; administrative fees from the energy purchasing central; real estate leasing in Charleroi Métropole business parks; and motor force tax verification services for Walloon municipalities. Pricing is not publicly disclosed and operates on customized project-based contracts funded through municipal budgets, Walloon regional subsidies, and public grants. The company maintains ISO 9001 (25 years), ISO 14001, ISO 50001, and EMAS certifications. Named customers include Belgian Defence (€600M Quartier du Futur), Ville de Charleroi (multiple school renovations with quantified energy savings), CPAS de Charleroi, and 70+ Walloon communes.
