General origin
Urban areas are facing enormous challenges
from population growth, industrialisation,
suburbanisation, climate change resulting in
escalating costs of water, bad conditions of
technical infrastructure and other risks.
Water resources are frequently threatened by
waste disposal, releases of industrial pollutants
and rainfall and runoff affecting water
availability.

Natural land
Influence of urbanisation on
urban water cycle



In highly urbanised areas, over one-half of all rain becomes
surface runoff, and deep infiltration is only a fraction of
what it was naturally. The increased surface runoff requires
more infrastructure to minimize flooding.
Natural waterways end up being used as drainage
channels, and are frequently lined with rocks or concrete to
move water more quickly and prevent erosion.
In addition, as deep infiltration decreases, the water table
drops, reducing groundwater for wetlands, riparian
vegetation, wells, and other uses.

IWRM as a good practices example

Integrated Water Resources Management (IWRM) as a response
to increasing pressures on water

Global Water Partnership definition of IWRM „a process which
promotes the coordinated development and the management
of water, land and related resources, in order to maximize the
resultant economic and social welfare in an equitable manner
without compromising the sustainability of vital ecosystems”

Goal of IWRM at river basin level:

Achievement of water security

Risk management

Effective and reliable delivery of water services

Coordinating and balancing the various water-using sectors as
a part of sustainable water management.

Goal of IWRM at urban level – need to be redefined including
specific local conditions

Climate change adaptation through strategic planning
 Social and economical studies related to the management of water
resources
 Integrated approach to environmental management with reference to
urban sprawl, population growth and economic development issue
 Promotion of participative dialogue model
 Identification of eco-innovation solutions reducing quantity of pollutants
drained with rainwater to water bodies
 Enhancing original methodologies for recycling or reuse of waste/rain
water on urbanised areas
 Elaboration of a set of assessment tools to benchmark urban areas
regarding implementation of river basin management principles


Benefits




Improvement of information on the effects that
different activities have on water resources
availability, use and quality
More effective transposition of environmental policy
including water issue on urban/postindustrial areas
Better understanding of interrelations between spatial
planning, pollutant discharge and quality of water
bodies (surface and groundwater) in reference to
specific local conditions
Networking collaboration between researchers,
decision-makers, ecologists and engineers in the
field of diminishing an intense pressure of urban
areas on ground-water environment
Conclusions

Complexity and commonness of this issue is a widespread challenge and
requires profound researches and studies including:

Spatial planning vs development of urban centres in economic and social
dimension,

Researches regarding sources and directions of pollutions discharge into the
environment (surface runoff, runoff from postindustrial areas and dumping
sites),

Implementation of Decision Support System (DSS), supporting practical aspects
of IWRM on postindustrial areas,

Best practices in identifying urban water cycle and implementation of IWRM,

Financial and legal aspects of environmental management in urban areas,

Eco-innovation research.

Due to crosscutting character of water issue in urban areas, there is a need
of effective networking of multidisciplinary teams and creation of
mechanism of stakeholders involvement.

Joint actions and cooperative initiatives should promote implementation of
eco-innovations in water sector and consolidation of research potential
across Europe
