SARL HYDRO ASSISTANCE INGENIERIE

What SARL HYDRO ASSISTANCE INGENIERIE does

SARL HYDRO ASSISTANCE INGENIERIE is a French private limited company (SARL) headquartered in Hinx, in the Landes department, operating as the engineering arm of the HYDRO ASSISTANCE group since its founding in 1999. The firm delivers specialized hydrogeological engineering services centered on water borehole diagnostics and rehabilitation, deploying five mobile diagnostic units capable of working on cased and open-hole boreholes down to 2,300 meters depth. Core technical capabilities include diagraphies (gamma-ray, resistivity, acoustic wall imaging, temperature-conductivity and flow logs, cement bond logging), high-pressure video endoscopic inspection (including a 100°C/200 bar thermal variant), stepped and long-duration pumping tests, depth-selective sampling via COFRAC-accredited laboratory workflows, hydrogeological studies covering aquifer characterization and regulatory dossiers, and works regeneration using brushing, air-lift, and chemical/mechanical treatments. The integrated sister division HYDRO ASSISTANCE INDUSTRIE adds a manufacturing and equipment line covering data acquisition units, pressure and flow sensors, physico-chemical probes, exploitation pumps from 2 to 10 inches (1–400 m³/h), and stainless-steel extraction columns with the patented HA/R2 quick-connect system (Brevet Hydro Assistance).

The company monetizes through two streams: project-based professional services (engineering diagnostics, hydrogeological studies, technical assistance missions, well rehabilitation) priced per scope, and industrial equipment sales plus installation (HYDRO ASSISTANCE INDUSTRIE). GTM is direct enterprise field services — multidisciplinary teams are mobilized to client sites in France, primarily within the Nouvelle-Aquitaine region. The customer base is concentrated in French water sector end-users and includes major water utilities (Veolia, Suez, Saur), bottled water and mineral water producers (Danone, Cristaline, OGEU), engineering consultancies (Artelia, Antea, Safege, Burgeap), drilling contractors, thermal spas, and the French geological survey (BRGM). The company is owner-operated under Gérant Sebastien Dangouma, has no external funding events on record, and operates from two offices (Hinx headquarters and Talence/Bordeaux agency). Pricing is quote-based and multi-year contract in structure, with no publicly disclosed price list, consistent with custom B2B engineering delivery.

Core offering

SARL HYDRO ASSISTANCE INGENIERIE provides specialized hydrogeological engineering and water borehole diagnostic services, including diagraphies, endoscopic inspections, pumping tests, sampling, hydrogeological studies, and technical assistance for drilling and rehabilitation. Its industrial sister division manufactures and installs measurement and production equipment, including patented HA/R2 quick-connect fittings and exploitation pumps.

Product overview

SARL HYDRO ASSISTANCE INGENIERIE operates as an engineering and industrial services company specializing in water borehole diagnostics and equipment. The company comprises two main divisions: HYDRO ASSISTANCE INGENIERIE provides specialized engineering services including diagnostic units for borehole inspection (diagraphies, endoscopic examination, pumping tests, sampling), hydrogeological studies, technical assistance missions, and works regeneration; HYDRO ASSISTANCE INDUSTRIE manufactures and sells measurement equipment (data acquisition units, pressure sensors, flow meters, physico-chemical probes) and production equipment (pumps from 2" to 10", exhaure columns with patented HA/R2 quick-connect fittings), plus installation and rehabilitation services. The divisions operate as an integrated offering where engineering diagnostics inform equipment specifications and rehabilitation services.

Broad incumbents

• SGS: Global testing, inspection, and certification company with water and environmental testing capabilities. Provides industrial measurement services at scale and overlaps with Hydro Assistance's measurement equipment and diagnostic activities.
• Bureau Veritas: Global testing, inspection, and certification firm with industrial asset services including water infrastructure. Larger incumbent that overlaps in industrial measurement and water-related compliance work.
• SLB (Schlumberger): Global oilfield services giant with deep expertise in well logging, downhole measurement, and pumping diagnostics. While focused on oil and gas, its well diagnostics technology and methods are technically transferable to water wells.
• Fugro: Global leader in geotechnical, geophysical, and subsurface investigation services. Operates at much larger scale with broader geographic footprint but overlaps with Hydro Assistance's borehole diagnostics and diagraphies offerings.
• Halliburton: Global oilfield services company providing well logging, drilling, and completion services. Operates at vastly larger scale in the well services space but serves an adjacent (not water-focused) customer base.

Emerging players

• BRGM (Bureau de Recherches Géologiques et Minières): French geological survey and public research institution conducting hydrogeological studies and groundwater resource management. Both organizations collaborate on French hydrogeology work but BRGM is a public research body, not a commercial services competitor.

Direct peers

• Safege (Suez Consulting): Suez subsidiary providing engineering consulting for water, environment, and infrastructure. Direct competitor in French water and hydrogeological engineering consulting.
• Burgeap: French geotechnical and hydrogeological engineering consultancy (Egis subsidiary) offering aquifer studies, well diagnostics, and environmental services. Direct competitor in French hydrogeological engineering.
• Antea Group: French environmental and water engineering consulting firm with hydrogeology expertise. Both compete for and collaborate on water well and environmental engineering projects in France, serving similar utility and industrial customers.
• Artelia: French engineering consulting firm with significant water, environment, and infrastructure capabilities. Competes for water engineering mandates and shares similar enterprise customers in the French market.
