Urban hydrology & sewerage

Every city has its own hydrological cycle of precipitation and inflow, storage and losses, and runoff, and differences between these cycles over the world are enormous. In the basis, however, urban hydrology is about two central themes: public health and keeping dry feet.

Because local circumstances vary so much, designs of urban hydrological systems also vary greatly. There is no standard blueprint. Factors such as soil characteristics, surface elevation, precipitation characteristics, the requirements and availability of fresh water, organizational elements and budget restrictions are parts of the puzzle that must be weighed and valued.

The importance attributed to these factors form the basis on which a vision and strategy can be built for the urban hydrology, which can then be implemented.

Every project that is carried out in the field of urban hydrology has a place in the process of further system development. Steps are continuously required, but with scarce means – budget, human resources, information position – you of course need to be sure that the right steps are taken. Urban development or drainage system improvements cannot be put on hold for a few years.

We feel at home in this field. Analysing the hydrological system and its current situation. Gathering information on relevant factors and their weights. Developing a vision and strategy that is realistic. Optimizing the cost and added value of the measures taken.


Typical issues:

  • What are the possibilities for a higher efficiency of sewer systems?
  • What are the effects of climate change to floods?
  • How does the input and output of the water system affect the chanses and mechnisms of flooding?
  • How can we optimize the input and output of the water system to prevent floods?
  • How can we design and construction information systems to support policy makers and decesion schemes?.
  • How does urban developments affect the water system and safety risks
