Almost endless options for your collection systems


From modelling surface runoff and flows to water quality and sediment transport, MIKE+ has all the features and functions to help you solve even the most complex collection system issues.

Simulate pipe and channel network flows

For both short and long-term collection system management, use MIKE+ to run simulations of subcritical and supercritical flow conditions in partial, full and pressurised pipe networks.


Simulate every aspect of your collection system using the MIKE1D Pipeflow module, including:


  • Standard and flexible cross-sections

  • Circular manholes

  • Retention basins

  • Soakaways

  • Overflow weirs

  • Orifices

  • Pumps

  • Flow regulators

  • Stormwater inlets

  • Junctions

  • Valves

Accurately assess water quality and impacts

Make advanced water quality assessments by combining the MIKE1D Pipeflow module with the Transport and MIKE+ ECO lab modules. Used together, you can conduct a city-wide network simulation of ecological, biological and chemical water processes.

  • Identify the cause and location of hydrogen sulfide formation

  • Test various mitigation options

  • Model stormwater quality

  • Evaluate LIDs treatment efficiency

  • Assess the impact of pollutant transport on rivers, lakes, and surfaces


Model stormwater and wastewater systems


Plan, design, and analyse your stormwater, sanitary and combined systems using the MIKE+ SWMM module. Evaluate low impact development designs, mitigation options and pipe capacity to ensure a high standard of service and cost-effectiveness.

Create dynamic models for:

  • Pipes, open channels, storage units, and more

  • Stormwater runoff from sub-catchments including LIDS

  • Stormwater routing by kinematic wave method

  • Infiltration by either the Horton or the Green-Ampt methods

  • Rainfall dependent inflow based on RTK method

  • Vertical movement of water infiltrating sub-surface groundwater zones

Evaluate low impact development (LID) initiatives

We all know stormwater can be managed more sustainably, but do you know which LID practice to pursue for your collection system? With MIKE+, you can model different LID practices at both the hydrological screening and detailed hydraulic level to evaluate their effects before making any investment.

Model and simulate LID practices including:

  • Bioretention cells

  • Rain gardens

  • Green roofs

  • Rainwater barrels

  • Permeable pavements

  • Infiltrations trenches

  • Soakaways


Easily couple collection systems and rivers


Most cities are built near rivers and are affected by them. With MIKE+’s transversal modules, you can model collection systems and river networks together to better understand their relationships.

With such insights, you’ll be able to:

  • Increase city resilience and liveability

  • Ensure sustainable stormwater management

  • Assess the impact of pollutant build-up and wash-off

  • Make long-term impact analyses

  • Simulate water quality processes and treatment options
