Sustainable Stormwater Management

Efficiently drain surface water while minimising pollution and its impact on water quality with smart, sustainable solutions to control and treat stormwater.

The issue

Urban landscapes continue to expand in the midst of a changing climate. Growing populations, development and densification combined with more frequent severe weather events is overwhelming traditional drainage systems. In cities with mostly hard surfaces, the pollution content in runoff from traffic, building materials and air pollution is threatening water quality in open waters.

Why it matters

To transform a city from a funnel into a sponge, the harvesting of stormwater within its water cycle should be considered for long-term, resilient water balance and reuse. Through vegetation, storage and infiltration, sustainable urban drainage systems (SuDS) or low impact development (LID) rely on natural processes to absorb, filter and break down pollutant substances to protect receiving waters and their biological environment from hazardous substances.

How we can help

The best way to minimise environmental degradation is to integrate the entire water cycle into your planning process. DHI supports the design and implementation of SuDS and LID for both new and existing developments. Through advanced hydraulic and catchment modelling, comprehensive risk assessments and flood mapping, your city can benefit from reduced runoff and improved water quality, efficiency and resilience to climate change.

Integrated solutions

Here are some ways DHI can help city planners, water utilities, municipalities and urban developers revitalise infrastructure and receiving waters for greener cities.

How to manage urban stormwater quality in three steps

To guide the selection of stormwater management options to reduce the impact of polluted stormwater runoff to water quality in receiving bodies, it’s necessary to characterise the catchment and untreated runoff quality both spatially and temporally. A spatial analysis and planning system can identify critical source areas for pollutant load reduction, prioritise mitigation based on contaminant influence on in-stream ecological health, and provide mitigation options through best practice stormwater management systems.

Shaping the future of our cities with sustainable urban drainage systems

Sustainable urban drainage systems (SuDS) or low-impact development (LID) are approaches in managing surface water. With efficient SuDS in place, governments and water utilities can better manage flood risks and water quality to improve spaces where we work, live and play. With many national planning policies now encouraging the use of SuDS, government and regulators are increasingly expecting this approach to be incorporated in new developments.

Sustainable stormwater modelling in cities using MIKE URBAN+

Making cities more sustainable involves managing a larger portion of the stormwater locally through the implementation of green solutions, surface storage and controlled surface flooding often combined with rehabilitation and an extension of existing infrastructure capacity. Register for this free 45-minute webinar to learn how MIKE URBAN+ can support these initiatives through various stormwater modelling options.
