Climate change

Climate change
  • Increasing the load on the sewerage networks and requiring more maintenance and higher quality pipes
  • Temperature and rainfall increases set to strain sewerage systems


increase in rainfall

Climate change has and will likely continue to increase the frequency of more extreme weather conditions, which has multiple effects on the underground infrastructure. UIM services offer solutions for handling the pressures placed on underground infrastructure caused by climate change, as a well-maintained underground infrastructure is essential to cope with increased precipitation and to reduce the risk of flooding.

The increase in extreme weather events due to climate change mean that capacity requirements of the day water systems must increase. More precipitation will lead to the water systems having problems handling higher water levels, which can lead to sewer flooding. It is not only high precipitation that strain the underground infrastructure, but extraordinary dry weather also may result in increased need for cleaning services such as underground infrastructure and water pipes, since the flow through the system from normal weather conditions result in self-cleaning. An expected increase in average temperatures may also lead to sanitation problems occurring in the drinking water supply system, due to possible bacteria contamination. Local weather conditions vary significantly with regards to precipitation intensity, topography as well as self-drainage capacity. Investments in the underground infrastructure can lead to better handling of extreme weather conditions, by increasing the retention capacity, both through more access points to the underground infrastructure and through higher storage volumes in the retention basins. Such investments in underground infrastructure, however, do not constitute a lasting solution, and municipalities will need to continue to address problems resulting from climate change. As a result, UIM services are essential for countries with extreme weather events as a result of climate change. In addition, climate change and an increased environmental awareness among customers have increased the importance of ESG as a scoring criterion, especially in public procurement processes, which further drives scale advantages within the industry and creates opportunities for premium pricing.
