coordination of actions as regards the degree of integration of the water resources
management system is further made difficult by the lack of conformity of the administrative division applicable to spatial planning with the division into drainage basins
and water regions (the catchment area division) in water management. Polish legislation lacks provisions comprehensively regulating local water resource development
practices which take into account the connection of metropolitan areas with the
catchment area arrangement. As a result the problem is frequently marginalised by
local self-government [27, 38, 39, 43, 44]. At the local level, there are no formal
planning documents pertaining to water management, while spatial planning has not
adopted the catchment area division as the basic area for planning and decisionmaking actions. This aspect should be considered at the stage of elaboration of the
integrated water resources management model recommended for implementation in
urbanised areas [28, 41].
18.4 The Metropolitan System of Water Resources
Management—A Case Study of the Pozna ´
n Metropolis
18.4.1 Location and Administrative Structure
of the Metropolitan Area
The Pozna´ n metropolis, which is discussed as a case study, is located in the western
part of Poland (Fig. 18.1) and covers an area of approximately 3,081 km
2 . Using the
OECD definition, the city of Pozna´ n together with its 21 adjacent communes constitutes a metropolitan area (Fig. 18.5). The city of Pozna´ n and suburban communities
form a monocentric settlement (the Pozna´ n metropolis) centred around the city of
Pozna´ n, which is surrounded by 21 communes. The Pozna´ n metropolis occupies
10% of the Province of Wielkopolska (Greater Poland), inhabited by more than 1
million people representing 29% of the total number of inhabitants of the province.
The population density is 320 residents per km, which is almost three times greater
than the average for Poland.
18.4.2 Resource Potential
According to the regional approach, the Pozna´ n metropolis is located in the central
part of the Wielkopolska (Greater Poland) Lowland, within the area of two Lake
Districts—those of Pozna´ n and Gniezno. The area’s low water abundance is attested
to by the unfavourable structure of the hydrological balance, which is determined
by the low sums of atmospheric precipitation (500–550 mm), high evaporation (in
excess of 500 mm), and low run-off and the high water deficits associated therewith.
The Pozna´ n metropolis is located within reach of the Warta Water Region, primarily
