Collection Systems

Confidently make collection system decisions

Design real-time controls, assess resilience solutions and manage rainfall-dependent inflow and infiltration (RDI) for both stormwater and wastewater collection systems.

Almost endless options for your collection systems

From modelling surface runoff and flows to water quality and sediment transport, MIKE+ has 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 various aspects 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
  • Storm water 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 with full access to 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 subcatchments 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 connect 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 washoff
  • Make long-term impact analyses
  • Simulate water quality processes and treatment options
  • Accurately represent the outflow of a river or pipe
  • Include the propagation of pollutants in your models

Document emergency storage requirements

With the new Pump Emergency Storage tool, you can easily calculate available emergency storage and time in the event of a pump failure – before reaching the alarm level or having a sewer overflow occur.

This powerful tool also enables you to:

  • Stop upstream flows of the failed pump
  • Locate the lowerst overflow level for each pumping station
  • Set your own pump failure time and custom alarm levels

More accurately analyse inflow and infiltration by integrating seasonal groundwater data from MIKE SHE

Seasonal variations in groundwater levels can significantly impact various processes, including wastewater management, stormwater control, and water quality assessments. To address these challenges effectively, the integration of seasonal groundwater data becomes essential.

By seamlessly coupling your Collection System (CS) networks with MIKE SHE, you can unlock a more comprehensive understanding of how these seasonal fluctuations influence your systems and make informed decisions for sustainable and resilient operations.


Additional capabilities & unique features

Streamline your work process with ease by viewing model results and input data side by side within the same editors. This simplifies the task of achieving ideal pipe network characteristics, allowing you to effortlessly adjust parameters based on specific criteria while simultaneously editing input data and reviewing the results. Say goodbye to the hassle of searching for matching data, like pipes, between two separate tables as previously required.

Explore the influence of snowmelt and irrigation through elevation zones, while enhancing your comprehension of river dynamics and precipitation patterns.

Introducing one of our latest features for enhanced results with a natural, precise, and gradual intensity distribution. With spatial rainfall intensity interpolation from rain gauges, you’ll enjoy smoother, more realistic outcomes.

Gain greater control over your catchment modelling process by defining multiple types of land uses within each catchment and customising loss/infiltration settings.
