Resilience measure: Increased capacity of sewer/drainage system


Increasing the capacity of the sewer/drainage system increases the ability of the system to drain excess surface water during heavy rains and prevent flooding. The capacity of stormwater systems may be increased by new and larger pipes when old pipes cause problems with flooding, pollution, etc. or even with maintenance works ensuring that the capacity of the system will be as designed (e.g. sediments trapped).
(Torgersen G., et. al., 2014).

Co-benefits and impacts

Increasing the capacity of the sewer system also decreasing the chance of sewage overflow into surface waters, especially for combined sewer systems.
