GREEN INFRASTRUCTURE - WATER SENSITIVE URBAN

DESIGN (WSUD)

The forthcoming MIKE URBAN 2016 adds advanced WSUD functionality enabling you to preserve and create natural landscaping features - as well as soakaways - to establish functional and appealing drainage systems. There are two approaches to WSUD modelling in MIKE URBAN:

At a screening level (watershed/catchment based), MIKE URBAN can be used to assess the cumulative impact of implementing various green solutions within a catchment. These can include:

Catchment based modelling of soakaways

Permeable surfaces

Bio-retention cells (e.g. green roofs)

Infiltration trenches

Continuous porous pavement

Rainwater tanks

Vegetative swales

At a detailed hydraulic modelling (drainage network based) level, MIKE URBAN allows detailed modelling of individual green solutions connected hydraulically to the storm water pipe network.

MODELLING OF WATER QUALITY OR TREATMENT IN

SUSTAINABLE DRAINAGE SYSTEMS (SUDS)

ECO Lab is the complete numerical laboratory for water quality and ecological modelling. You can develop exactly the model you need and describe the processes you wish. No ecological problem is too simple or too complicated for ECO Lab:

Open Equation solver for coupled ordinary differential equations

Designed for point descriptions of processes of chemistry, ecology, etc

All equations, parameters contained in flexible, portable ECO Lab templates (use DHI supported templates or create your own)

Integrated with DHI’s hydrodynamic models.

Use of MIKE URBAN to model the water quality and treatment processes in soakaways:

The pollutants on the surface can be modelled dynamically using build-up and wash-off processes – or connected as a constant to calculated runoff directly

Pollutants enter the soakaway with captured runoff and treatment efficiency is modelled with ECO Lab

If the soakaway is connected to a drainage network, the remaining pollutants will be modelled in the pipe by MIKE URBAN’s Pollution Transport module

Treatment processes include sedimentation, adsorption and biological processes, and can include for dissolved COD, ammonia, total N, dissolved P, total P, heavy metals and coliforms among other constituents.

AUTOMATED SEWER MODEL SYSTEM FOR PUB,

SINGAPORE’S NATIONAL WATER AGENCY

In collaboration with PUB, Singapore, DHI has developed a new and innovative sewer planning support system based on MIKE CUSTOMISED technology. The new system, developed in accordance with PUB’s established work processes and specification, provides near full automation of network modelling in order to quickly and effectively assess the implications of any land-use changes to the sewer network.

The system allows PUB’s Catchment Managers to synchronise updated asset data, within their existing GIS database, to a newly created catalogue of sewer models in order to check the adequacy of the existing sewer network, and to plan network expansion to serve new urban development. On a scheduled basis, the system interrogates the GIS database for changes, automatically updates the MIKE URBAN sewer models, performs validation checks, runs a simulation, and then re-catalogues the updated sewer models. The user interface allows for easy creation and maintenance of the sewer network models, and the system can even send error reports to the managers should models fail to validate.

In order to build the sewer models, the system has native support for MIKE URBAN but a variety of hydraulic models may be incorporated into the model creation and maintenance processes.

With MIKE INFO you can create your own automated model system for storm, foul and clean water networks.

Optimise the capacity of YOUR drainage infrastructure and improve water quality by a unique hybrid approach of retrofitting sustainable urban drainage systems and smart management of storm water.

DHI BATHING WATER FORECAST SERVICE FOR AARHUS

More than 300,000 people live in Aarhus, Denmark’s second largest city. The city, like many other coastal cities, has recently undertaken the task of restoring its old industrial harbour area into residential and recreational use. Aarhus Water – the local water company – has 10 wastewater treatment plants that receive 35 million m3 of wastewater per year. In 2005, the receiving waters were affected by 75 combined sewer overflows (CSO) spills and discharges from 58 storm water drains. In addition, 50% of the flow in the river comes from two wastewater treatment plants.

To support the opportunities for recreational use of the lake, river and harbour, the City of Aarhus decided to improve the hygienic water quality in these receiving waters. In more measurable terms, this decision was driven by the European Water Framework Directive and the Bathing Water Directive. Faced with the demands of a growing city, climate change and the increased demand for recreational use, Aarhus needed to find a way to increase their wastewater treatment efficiency and capacity, ensure hygienic bathing water in Lake Braband and the harbour and improve water quality in the River Aarhus. Adding new machinery and tanks would have strained the city’s finances, so they turned to DHI to find a cost-effective solution.

THE DHI SOLUTION

The DHI solution was to develop a X-band Radar based, integrated real-time control, optimisation and warning system for urban areas and receiving waters.

Built upon MIKE OPERATIONS and underpinned by fully integrated hydrological and hydraulic models which include the upstream catchments, sewer network (including retention basins), rivers and lakes, the coastal environment and the Waste Water Treatment Plant (WWTP). The new system was used to assess the optimal location and size of additional retention basins and to optimise the control of the sewer system and WWTP. Aarhus Water’s ultimate investment in new infrastructure (consisting of retention basins, disinfection at WWTP and increased hydraulic capacity at WWTP) represented a significant saving over the original proposals (without the optimised control system).

The X-band (DHI LAWR) radar optimised control system enables storm water to be stored and moved around the system depending on where the rain is falling and the intensity of that rainfall. Following a period of construction and commissioning, the project has now delivered the original aims (hygienic bathing water in Lake Braband and in the harbour and improved water quality in the River Aarhus) plus multiple supplementary benefits including mitigation of the risk of surface water flooding due to our changing climate.

Integral to the project is a forecasting service to provide the public with information on the forecast bathing. The forecast is delivered via a web-based public warning system at

newostjylland.badevand.dk and DHI’s Bathing Water App.

The Aarhus project sets the global standard for others to follow and is an example of a truly integrated catchment forecasting system which includes real time operational control and optimisation.
