Stormwater management –
A project focus of KURAS
Building/plot level
City quarter level
Planning of measures on buildings generally focuses on residents.
Responsibility lies with the private or public owner.
.
.
Measures in city quarters are planned with a focus on residents and on water-management
requirements. Responsibility generally lies with the public sector.
De-paving
Vegetated buildings
• Partially sealed surfaces
• Extensive and intensive green roofs
• Green facades
Infiltration
Rainwater harvesting
• Through a biologically active soil layer
• Underground
• Combined (percolation/retention)
• Special forms
• Irrigation
• Indoor cooling
• Service water
Infiltration (on site)
Artificial ponds and streams
• Through a biologically active soil layer
• Underground
• Combined (percolation/retention)
• Special forms
• Ponds
• Water-carrying trenches
Treatment
• Decentralized treatment at the gully
Building/
plot level
City quarter level
Sewer catchment level
Sewer catchment level
Measures at the level of the sewer catchment area generally built to fulfil
water-management requirements. Responsibility generally lies with the operator of
the sewer network and the public sector.
Treatment
• Sedimentation basin
(separate sewer system)
• Lamella particle separator
• Retention soil filter
• Special forms
Storage capacity in sewer
• Retention tank
(combined sewer system)
• Retention sewer
(combined sewer system)
• Storage activation
(combined sewer system)
• Retention basin
KURAS has considered the potential of stormwater
management at three spatial scales: at the building/plot, the city quarter and the sewer level. Both
the measures and the responsibilities differ among
these levels. The initial aim of KURAS was to evaluate the impacts on residents, the environment and
economic aspects in a uniform manner. Based on this
evaluation, a method was developed that can support
the integrated planning of measures for stormwater management for specific urban neighbourhoods.
The results show that the combinations of measures – from building and quarter levels through to
sewer catchment area – that were developed using
the KURAS method for two Berlin neighbourhoods
(in Schöneberg and Pankow) significantly improved
the targeted effects for the environment and for
residents.
The following effects were evaluated as part
of KURAS:
Residents
■■ Building physics and services
■■ Landscape quality
■■ Urban climate
Environment
■■ Biodiversity
■■ Groundwater/soil passage
■■ Surface waters
Economic aspects
■■ Costs of measures
■■ Use of resources

sustainable development
