Hidroing

What Hidroing does

Hidroing d.o.o. is a privately held Croatian engineering consultancy founded in 1990 and headquartered in Osijek, with a secondary office in Zagreb. The firm specialises in the design, supervision, consulting, and engineering of hydraulic structures, including water supply systems, wastewater collection networks, wastewater treatment plants, river regulation works, irrigation infrastructure, port facilities for river traffic, and flood protection structures. Service offerings span the full project lifecycle — feasibility studies, master plans, conceptual and preliminary designs, main and detailed construction designs, environmental impact assessments, construction supervision, and EU funding application documentation. The underlying technology stack centres on specialised hydraulic modelling software (Epanet, WaterCAD, WaterGEMS, Urbano-Hydra) combined with mainstream CAD and BIM tools (AutoCAD, Revit, 3D Max, Canalis) and GIS/stormwater tools (ArcGIS, EPA SWMM).

Hidroing operates a B2B professional services model, delivering project-based engineering work under quote-based, multi-year contracts to Croatian municipal water utilities, municipal governments, state water management authorities (notably Hrvatske vode), and construction prime contractors. Pricing is determined per project by scope and complexity; no standardised pricing tiers are publicly disclosed. The firm's revenue streams are exclusively professional-services engagements: engineering design, construction supervision, environmental impact studies, and EU project documentation preparation. The go-to-market is sales-led, relying on direct enterprise engagement, long-term relationships with scientific institutions (Faculty of Civil Engineering Zagreb and Osijek, TU Darmstadt IWAR Institute, University of Osijek Department of Biology), a project reference portfolio on its website, and participation in industry conferences. The company operates without app products, APIs, external integrations, or disclosed funding, and reports approximately 30-40 employees across engineering, environmental, supervision, and finance functions, led by long-tenured directors.

Core offering

Hidroing is a civil engineering consultancy providing design, supervision, consulting, and engineering services for hydraulic structures in the water management sector. The company prepares feasibility studies, master plans, conceptual solutions, preliminary, main, and construction designs; conducts environmental impact assessments and ecological studies; and delivers professional supervision during construction. It also prepares study documentation for EU co-financed projects (Cohesion and IPA funds) for water supply, wastewater drainage and treatment, river regulation, irrigation, and port infrastructure.

Product overview

Hidroing is a civil engineering and water management consultancy that offers a comprehensive portfolio of professional services rather than a unified software product. The core offering consists of engineering design and consulting services for hydraulic structures, organized into distinct service categories: water supply systems (vodoopskrba), wastewater drainage (odvodnja otpadnih voda), wastewater treatment (pročišćavanje otpadnih voda), river regulation and irrigation (regulacije i navodnjavanje), environmental protection (zaštita okoliša), EU funding study documentation, and construction supervision. These services are delivered by specialized sectors within the company and are applied to projects across water supply networks, sewage systems, treatment facilities, flood protection, and port infrastructure.
