Drainage installations for diverting surface water away from buildings and increasing retention an infiltration
Predefined flow routes aiming on diverting surface water away from building can be built on the property or along its boundaries, e.g. by a change in gradient, ground sills, creation of depressions or by building of water diverting structural elements like walls. Areas on the property such as basins or trenches may be constructed for collecting the water and providing a controlled infiltration into the soil. Definition of requirements by municipality is possible.
Synergies may exist between heavy rain risk management measures and other development goals like environmental protection, health care, and economic performance. Harnessing them requires involvement of different actors, enforcement of exchange between you and them and holistic thinking.
