Climate actions
Construction of urban water system elements for draining rainwater (canal systems, infiltration wells) and improvement of infiltration capacity. The effectiveness of the measure can be low; the structure requires maintenance and is more expensive than the underground system; conflicts with other urban uses may arise.
Water drainage
Objective
Drain rainwater.
Description
Expected results
Implemented and optimized surface or underground canal system through: infiltration ditches, basins, wells, galleries, systems of ditches and ponds or similar; reduced sealing surface by building water-permeable pavement; reduced flooding during peak flows, increased life quality, and improved biodiversity.
Result indicators
Area of water-permeable pavement [m²]
Length of water system elements [m or km]
Involved actors
Municipalities and technicians.
