Less water lost. Every pipe accounted for.

Hidromodel builds hydraulic models, cuts water losses and maps networks for water utilities — in Croatia and around the world, since 2009.

What we do, in one sentence

We make a working digital copy of your water network, measure how it really behaves, and use both to find where water is being lost — then help you fix it, zone by zone, without wasting a metre of pipe.

Six ways we help a utility run tighter

Water-loss reduction

Metered zones, pressure management and an action plan that shows where the water goes and how to keep it.

Hydraulic modelling

A calibrated model of your network, checked against real measurements, so you can test changes before you dig.

Network improvement and master plans

A long-term development plan, conceptual designs and cost estimates that stand up to EU and bank reviewers.

GIS and digital maps

Every pipe, valve and meter on one current map your whole team can open in the office or on site.

Site investigation and due diligence

Flow and pressure logging, valve and manhole surveys and an honest assessment of the state of your system.

Training

Hands-on courses in WaterGEMS and GIS for your own engineers, from first model to full calibration.
