BEPG

What BEPG does

BEPG is an independent French engineering consultancy (SARL) founded in 1987 and headquartered at the Technopole Nancy-Brabois in Villers-lès-Nancy, operating in the Grand Est region. The firm provides project-based professional services covering drinking water supply networks, hydromorphological diagnostics of watercourses, stormwater management, collective and non-collective sanitation, regulatory dossiers (Water Law, DIG, DUP), project management assistance (AMO), wetlands delineation, and contaminated sites studies. Its primary customers are local and regional public authorities across the Grand Est — communes, intercommunal structures (EPCI), water and sanitation syndicates (SIAEP, SIVOM, SIE), and departmental and regional councils — with a secondary base of property developers, industrial operators, and private individuals requiring non-collective sanitation or contaminated-land assessments.

BEPG's technical delivery rests on a stack of specialised hydraulic, hydrological, GIS, and CAD tooling that includes RIDROLO (its own proprietary modelling software), HEC-RAS, HEC-HMS, Mike-Urban, QUALPHY, ArcGIS, QGIS, and AutoCAD. The firm is OPQIBI-certified in AMO, water resource protection, sanitation, and water distribution networks, a credential that is effectively required for many French public-sector tenders. RIDROLO is also released as a free mobile application (RIDROLO Lite) for limited public use.

The business model is professional services revenue delivered through public procurement tenders (marchés publics), with quote-based per-project pricing, deposits at order, and balance payment within 30 days of invoice. BEPG markets primarily through its institutional website, regional press coverage, and memberships in HYDREOS, REVER, and ASTEE rather than active digital channels. The firm is privately held with no disclosed external investors, no subsidiaries, and no recorded M&A or funding activity.

Revenue model

1. Engineering and Consulting Studies: BEPG generates revenue through project-based professional service contracts delivering technical studies, hydraulic modelling, environmental assessments, and GIS solutions to public-sector clients (collectivités, municipalities, water syndicates). Contracts are typically won through public procurement tendering (marchés publics). Projects range from preliminary studies (AVP) through to full engineering design (PRO), tendering (ACT), site supervision (VISA, DET), and acceptance (AOR). Pricing is quotation-based, with deposits required at order and balance due on delivery within 30 days of invoicing.

Core offering

BEPG is an independent French engineering bureau d'études that delivers project-based water, environment, pedology, and geology studies to local and regional public authorities. Services span the full project lifecycle — preliminary studies (AVP), detailed design (PRO/ACT), site supervision (VISA/DET/AOR), and regulatory dossier preparation (Water Law, DIG, DUP) — covering drinking water, rivers, stormwater, collective and non-collective sanitation, wetlands, polluted sites, and GIS-based asset management.

Product overview

BEPG is an independent engineering consultancy firm founded in 1987, offering comprehensive studies and services in water and environment. The firm operates through specialized consulting service lines rather than a unified software platform: RIDROLO is their proprietary hydraulic/hydrological modeling software; the core service portfolio covers drinking water supply, waterway studies, stormwater management, collective and non-collective sanitation, regulatory dossiers, project management assistance, wetland studies, polluted sites studies, and Geographic Information Systems (SIG). Services target local authorities, professionals, and individuals primarily in the Grand Est region of France.

Targeted at municipalities, syndicates, and landowners lacking in-house project management capacity.
• Wetland Studies (Zones Humides) Wetland determination and delineation through soil surveys, diagnostic studies for sewage treatment plant siting, ICPE site studies, and environmental compensation studies. Targeted at local authorities, industrial operators, and developers.
• Polluted Sites Studies (Sols Pollués) Simplified risk evaluations (ESR) for potentially polluted sites, environmental studies for industrial reconversion, field investigation plans, and construction recommendations. Targeted at property developers (e.g., Nexity Foncier Conseil), landowners, and public land agencies (e.g., EPF Lorraine).
• Geographic Information Systems (SIG) Creation of databases, georeferenced field surveys, SIG solution installation, and training for local authorities to manage geographic and infrastructure data. Targeted at communes and EPCIs that need to map and maintain their water/sanitation assets.
