Wastewater collection systems

Collection systems are as important as distribution systems. They can have a severe impact on environmental and sanitary issues if capacity and maintenance are inadequate. Overloaded systems will overspill and may flood streets and basements with contaminated water.  This water can carry and spread diseases. Overloads also accelerate the production of hydrogen sulphide which corrodes the systems. 

The supply of fresh water has the first priority, but the second priority to get rid of the wastewater is just as important.

Sewer systems require massive investments to establish and are costly to maintain. Particularly as the pressure on the systems increases as urbanisation develops and the effects of climate change become more pronounced. Investments and maintenance costs can be reduced by planning and operating the systems more efficiently by incorporating innovative solutions. 

Even existing systems can be utilised better by implementing decision support systems, which enable the operators to maximise the utilisation of the capacity more efficiently.

Mapping the actual capacity of the system provides the overview. The next step is to optimise the utilisation, pinpoint the bottlenecks and design the appropriate alleviation measures.

Urban water management

By addressing the entire hydrological cycle and focusing on the interconnected nature of this, sustainable water policy and management can be developed. The aim is to protect the environment and resources and at the same time foster growth and sustainable development to the benefit of society. It provides a measure to deal with the issues in a holistic manner as it brings the stakeholders together.


Drinking water and distribution systems

DHI technology and methods enable authorities, designers and operators to address entire distribution systems, pinpoint leakages and operate more efficiently in order to meet demands. Combing on-line measurements of water quality and discharging with dynamic models which address all the relevant issues provides the understanding of how the system functions.


Water utilities

The future requires innovative solutions based on years of experience and the ability to quantify the implications and develop appropriate measures. Rapid urbanisation combined with the implications of climate change is one of the major challenges society faces now and decades to come. Urban water management integrates the various stakeholders and is an important step towards sustainable development.



Our consulting services are backed by our competencies within development of software tools and within the acquisition of information from nature, as well as services provided by our various laboratories and testing facilities. To do so we apply our methods and technology within the DHI Group and do so in close cooperation with you - thus making key resources available regardless of your location or the technical challenge.
