1. Scenarios for Urban Water Management:
Europe and Developing Countries
Prof. Dragan Savic

2. Urban Population

3. Urban Water: Supply and Distribution
Groundwater Source
Storage
Lake or Reservoir Source
Consumers
Water Treatment
Pumping

4. Urban Water: Wastewater Systems
Waste Water Treatment
Rainfall
Combined System
Receiving Waters
Sanitary Sewer

5. Urban Water Systems River catchment - unit of analysis (EU WFD)
a vital component
to be integrated
Important impacts
human health, environmental protection, quality of receiving waters, water demand, affordability, equity, recreation, amenity, and stakeholder satisfaction

6. How to manage all this? Urban Water: Europe
Source: D. Macaulay. ‘Underground’. 1976
Tighter financial climate (private / public)
Sustainability, but need to demonstrate “value for money”
Uncertainties about current system state (e.g. where are pipes, what state they are in, deterioration, etc)
Uncertainties about future (technical, environmental, economic and social)
How to manage all this?

7. Urban Water: Developing World
Increased urbanisation!
Over 1 billion people, or 18% of the world's population, lack access to safe drinking water
Over 2.4 billion people do not have adequate sanitation
The EU Water Initiative
to halve the proportion of people lacking access to safe drinking water by 2015
similar target for sanitation
How to manage all this?

8. Main Goal
Design and manage sustainable systems so that they perform reasonably well in the face of significant uncertainty

9. Scenario Elements for UWM
Baseline Scenario - “Business as usual”
Continuation of current policies and trends
6-fold increase in demand, 3-fold increase in population (historical)
Climate Change
Change in precipitation, temperature, etc.
Technological/Economic Change
Improvements in efficiency of water use
Decentralised (on-site) treatment
Socio-economic Change
Changing values and behaviour (demand, re-use, recycling, public-private partnership)
UNCERTAINTY & SCENARIO GENERATION

10. Current EU UWM Projects
CityNet
a cluster of 6 ongoing EU FP5 projects dealing with urban water issues (47 R&D institutions)
an EOI for an FP6 NoE on Integrated Urban Water Management (200+ R&D institutions)
Aquarec
Integrated concepts for reuse of upgraded wastewater (EU FP5 project), 22 partners
as a fresh water substitute primarily for non-potable use

11. Current UK UWM Projects
Five UK Universities with “Platform” grants
Cranfield, Exeter, Imperial, Sheffield & Bradford
WaND (Water) & CoDES (Decision Support)
Two of 14 consortia in the “Sustainable Urban Environment” programme
Whole-life costing projects
DSS for water supply and distribution networks
DSS for wastewater networks
Flooding Consortium
Climate Change Consortium (Audacious)
