This document discusses integrated urban water management (IUWM) as an approach to address water security challenges in cities. IUWM takes a holistic view of the urban water cycle and involves stakeholders across sectors. The document outlines the principles of IUWM, including considering the entire water cycle as one system and integrating social, institutional, geographic, inter-sectoral and governance aspects. Case studies from Durban, Singapore, and Dakar demonstrate benefits of IUWM such as cost savings, job creation, increased water supply and improved sanitation. The document concludes by describing IUWM modules and programs that can be implemented to plan and finance IUWM projects at the city level.

2. 1. Introduction
Urbanization will be the defining trend over the next several
decades. Today, 50% of the world’s 7 billion people live in cities,
and, by 2050, this will rise to 70%.
Current models of urban planning and water management are
not always effective from the perspective of cost effectiveness,
technical performance, social equity and environmental
sustainability.
A change in water management approach is needed in
order to face existing urban water challenges but also to better
shape the emerging cities of tomorrow.
Integrated Urban Water Management (IUWM) is an
approach that is holistic, considering the entire water cycle as one
and involving all relevant stakeholders.

3. Integrated Approach
Integrated
Approach
One Cycle
(Sanitation,
Stormwater,
surface
water,groundwater
, wastewater)
Social
(Poverty
reduction,
inclusivenes,
gender)
Institutonal
(Involvement of
all stakeholders)
Geographic
(River Basin
Catchment
management)
Inter - Sector
(WRM, water
supply, sanitation,
energy, urban
agriculture)
Governance
(Public, private,
social
partnerships,
decentralized
systems)
URBAN WATER
SECURITY

4. Advantages of An Integrated Approach
• Get a holistic overview of current water uses and balance interests
and needs of users
• Ensure selection of appropriate solutions and reduce duplication and
contradiction of activities
• Increase awareness, cooperation and ownership
• Increasing Efficiency of Water Use – Reuse, Recycling, Demand
Management
• Increasing portfolio of water resources – stormwater, rainwater,
wastewater
• Positive Economic Impacts: Urban Agriculture, Job creation, savings
in expensive water treatment etc.
• Increased resilience against Floods and Droughts
• Effective River Basin and Catchment Management

5. Durban Experience....
Challenges:Poverty and job creation, Food security, Energy constraints, Migration,
Growing informal areas, Water demand, Climate variability
Beneficiation Strategies: Non-revenue water reduction, Improving service levels, Re-use of
treated effluent, Biodiesel from Microalgae, Deep row entrenchment
of sludges, Mini and pico hydro, Water Reuse, Rainwater
harvesting, Use of effluents in agriculture, Stormwater and drainage
Approach: Integrated Water Management involving all stakeholders and integration through
various sectors and governance. Also 3 levels of service: Regulated supply of
200kl/per day (free basic), Semi – pressure, Full pressure

6. This program has realized savings
of R310m in the past 3 financial
years at EWS at a cost of
R152.6m
Results
5/5/2014 6
Job Creation with more
than 60000 new jobs
Increased energy
generation
Less firect discharge to
sea

7. Singapore Water Story
Challenges: High Population and economic
growth, 2 water sources: catchment, imported
water from Malaysia, Low Sewer coverage, High
Non Revenue Water
Approach: New Partnerships (PPP, Stakeholder involvement), Investing in Research and
Innovative Projects and Approaches
Increasing Water Supply + Managing Demand
Collecting every drop- rainwater, stormwater etc Leakage Control, Education
Collecting every used drop- water storage, Water Tariffs
increasing catchments
Recycle and Reuse

8. • 4 National Taps/Water Resources -
Resilient supply of water
• Unaccounted for Water below 5 % –
One of the lowest in the world
• Domestic water consumption per
capita reduced to 153 litres/day
• 100% of population served by potable
water at the tap & 100% modern
sanitation
• Integrated urban and water planning
to enhance the quality of our living
environment

Singapore Water Story

9. Constraints: No Town Planning Code; No correlation between land rights and
customary rights; Agricultural production areas transformed into dwelling place
9
APPROACH:
• Assessment of health risks associated with the use wastewater - Identification of
hazards in irrigation water, Identification of hazards in agricultural field, Risk analysis.
• Best practices for risk management - Promoting the use of treated wastewater,
Effectiveness of good agricultural practices, Consumer protection, Protection against soil and
groundwater salinization.
• Policy , legal and institutional aspects- Update of legal and regulatory framework,
Awareness of the administrative authorities and local communities for better management of
urban agriculture and Peri-urban agriculture, Promotion of master plans incorporating urban and
peri-urban agriculture and creativity
Urban Agriculture in Dakar (Senegal)

10. Results
• 60 % of the total production of
vegetables come from urban
agriculture(lettuce, pepper, onion,
tomato, cabbage, carrots, turnips)
• 250,000 people get most of their
income from market gardening
• Main sources for this production
:Used water, treated waste water,
national water supply.
• Potential to do much more: 300 000
m3 treated used water produced for
discharge, and only 6000 m3 is
being used !!!

11. IUWM Modular Approach

12. IUWM Modules
• A basic IUWM Awareness Raising Module - designed to be implemented in a
one day event, targeting decision makers, urban planners and senior water sector
managers.
• 3 Kick-Off Modules – Following a cascade approach, these are designed to be
implemented as first steps at city level, in guiding decision makers, planners and
facilitators to get organized for the implementation of IUWM.
• 4 Planning Modules - designed to be implemented as the next step To make
water balances, economic assessments, technology selection and Support city
Planners to develop IUWM Proposals.

13. IUWM Awareness Raising Module
It includes awareness raising and case building on IUWM and
consensus building from decision makers, financing partners and other
stakeholders to develop a common vision and goal. The main aim
here is to generate political will to induce an IUWM approach at
national or city levels and to get financial backing for the same.

14. KICKOFF Modules - 1
Manual for stakeholder Engagement - Tool to provide
direction on identifying the relevant stakeholders support in
facilitating communication in stakeholder processes and
engagement in planning
Institutional mapping tool - guide for effective institutions.
It starts with a mapping process of interests and relationships
among different institutions relevant for IUWM. These
relationships can be compared to effective IUWM institutions
and suitable transition steps can be identified and developed.

15. KICKOFF Modules - 2
IUWM Diagnostics Tool – To evaluate and appraise
cities for their readiness to implement IUWM in
different spheres. A suitability index will also be
developed to compare the readiness.

16. Planning modules - 1
Urban Water Balance Modelling Tool - to identify
additional water sources, prioritizing their selection, and
assessing water flows and contaminant fluxes capturing
developing country conditions such as on-site sanitation
(i.e., pit latrines, septic tanks) and different water users
(i.e., public taps, yard taps).
Technology Selection Tool - to identify and select
technologies appropriate to implementing the principles
of IUWM such as sustainable sanitation, water demand
management, leakage management, greater recycling,
resource recovery (energy and nutrients), cascading water
use and water neutrality.

17. Planning modules -2
Economic assessment tool - tool will support
better economic and financial development
decisions. The tool will provide a way to look
beyond the bottom line of capital outlays.
Project development and financing - This
module will guide city planners in Working out an
IUWM Project proposal within existing urban
planning formwork and strategies, and will be
proposing various financing options
