Hydraulic modeling software for pressurized pipe systems

For almost 40 years now, SIR 3S has been the leading software for the (thermo-)hydraulic calculation, simulation, analysis and optimization of flow processes in supply networks: Gas/water/heat, plants, pipelines and caverns. SIR 3S offers a variety of different calculation options ranging from analyses of the actual state to planning calculations for individual operating and expansion states as well as transport calculations through to questions for operational simulations and automation.

  • Steady-state hydraulics and extended period simulations
  • Transient hydraulics including pressure surges, water hammer
  • Safe, efficient and optimal system operations

The simulation software for your asset management according to ISO 55000

KANEW 3S® has been supporting strategic, tactical and operational rehabilitation planning for network management in accordance with ISO 55000 for over 30 years. The software can be used to include all operating resources, e.g. pipes, valves or systems, individually or in combination with each other in the various analyses and planning simulations. The range of applications extends from the optimum asset strategy to risk analyses and proposals for measures for re-investment priorities.

  • Condition assessment and reliability
  • Risk assessment and management
  • Asset strategies

Hydraulics for wastewater treatment plants and open channel systems

HYDKA 3S is used for the steady-state calculation of hydraulic losses in open and closed channel systems and was developed for modeling complex hydraulic processes in wastewater treatment plants. HYDKA 3S calculates flow rates, water levels (pressure lines) and energy lines. This can involve complex hydraulic systems with branched and meshed channels and pipelines in single and multi-line plants.

  • Hydraulic dimensioning of channels and pipelines
  • Verification of load cases and process concepts
  • Solution of hydraulically caused operating problems
