GESTAR offers the most complete software package for engineering pressurised irrigation systems (collective distribution networks and systems for use in irrigation on plots). Its tools and modules, specifically designed for pressurised irrigation and tested over the long term, enable optimum design, execution and management, integrating a wide range of resources, many of them available exclusively in this programme, and a long history of innovations and application to large and small systems.

 Some of its principal features are summarised below.

• Integration of modules for optimisation, hydraulic analysis and analysis of energy in the same environment, making these tasks easier and more convenient, while more importantly, enabling much more economic and reliable solutions to be found than those obtained in processes simply based on optimisation routines. 

• High optimisation levels for branching networks with a set layout, with multiple options, protocols and handy tools for finding solutions with substantial reductions in system costs.

• Hydraulic analysis module, unique in its robustness, flexibility and efficiency, developed specifically and with exclusive capabilities, such as Inverse Analysis, effective treatment of low resistance elements and regulating valves, general modelling of individual and lateral emitters with pressure-dependent flow emitted, pump performance curves with inflection points, modelling of direct pumping stations, etc.

• User-friendly intuitive graphic interface. All modules and tools, while making intensive internal use of advanced numerical procedures, are transparent to the user, in an intuitive graphic interface.

• Interoperable environment using the ACCESS standard as an intermediary for communicating with all types of CAD/GIS systems or third party programmes, as well as utilities for bidirectional communication with AutoCAD. Exporting of nodes and conduits to EPANET.

• Integration of many innovative tools (generating scenarios, alarms, filters, evolution over time, configuration of pipes with en route consumption, emitters, etc) conceived and developed thanks to extensive experience in network design and modelling.

• Availability of databases for pipes, valves, singular losses, sprinklers, drip branches, fluids, electricity prices, pumps, etc.

• A single platform for all users and every stage in the development of systems (project, execution and exploitation) letting you transfer, change and update the model interactively, giving instant results for the effects of any change or adaptation of the initial project in construction or during use.
