Abstract
Urban flooding is an increasingly common phenomenon around the world. The reasons are
usually attributed to the insufficient capacity of the combined sewer system and its inability to adapt
to the changing dynamics of rainfall. This is also the case inWarsaw (the capital of Poland), where the
sewage system was designed in the 1960s. The aim of the article is to highlight possible hydrological
solutions that would significantly improve Warsaw’s situation in terms of rainfall runoff. The article
looks at some solutions that were previously mentioned in the literature and presents an assessment
of the possible changes in land use/land cover on the hydrological processes and improvements
in the general hydrological situation of Warsaw. In addition, the article points out the need to
update the programme and spatial approach to the discharge of water from specific watersheds
in Warsaw, as well as to establish a single manager for stormwater drainage in the city of Warsaw.
An important issue is the restoration of natural retention basins in the city and the construction
of artificial basins in places with frequent local flooding. The article emphasises the importance
of building individual detention basins (as well as low-impact developments) for newly planned
investments. Other important aspects are as follows: the construction of suitable underground or
open channels, the need to disconnect Ursynów’s stormwater runoff from the catchment area of the
Słu ˙ zewiecki Stream and to channel it along the southern bypass for Warsaw (S-2) to the dry lakes
and ponds in Wilanów. Finally, the article discusses the application of Sustainable Drainage Systems
(SuDS) and Real-Time Control (RTC) in urban drainage systems as a possible solution to improve
wastewater management in urban areas.
