There is a growing challenge in providing quality water to communities and serving the rapidly growing cities with efficient water supply, drainage and wastewater systems. The demands for improving and protecting the environment and human health conditions are also increasing. One of the major challenges in the 21st century is to decouple economic growth from environmental degradation.

Freshwater is a precious resource. Providing high quality drinking water and efficient drainage and wastewater systems for the world’s growing communities and cities is a formidable challenge. The impact on urban flooding, combined or separate sewer overflows, treatment processes and receiving waters are high priority issues worldwide. Both the scientific community and the United Nations anticipate resource efficiency for industrial production to increase by a factor of four corresponding to a doubling of production using half the present resource consumption in the coming 20 to 30 years. DHI contributes to industry by making the numerous and complex water-related challenges manageable – from sewers to wastewater treatment plants and flood risk assessment.
