Urban drainage and climate change (completed 2008)
Climate change, e.g. more intense rainfall events, will affect urban drainage systems, and cause problems in cities. There is a need to understand and assess these impacts and consequences better. In many cities in Sweden, the rate of renewal of pipe systems is very low, but it is likely that renovation activities will increase. When urban water systems are replaced, climate change must be considered. The design of the future urban water system must take the climate change into account. What will be the problems and/or the possibilities? Which water system will cause most problems in a technical way or in an economical? Will it be a more energy demanding system? Will the systems be less sustainable?
