A new Specialist Group on W2SM
First years of the 21st century have been marked
by several disasters of great magnitude and
diverse origins. What they all have in common is
their damage to water supply systems and direct
impact on the population
  • destruction of the twin WTC towers in New-York,
  • major flooding in eastern Europe,
  • tsunami in Asia and Africa,
  • earthquakes in Pakistan and India,
  • pollution of a major river in China,
  • hurricane Katrina in Louisiana and Mississippi….

Long before the return to normal life, partial
restoration of a tolerable situation for the
affected people greatly depends on the
availability of safe drinking water.
? In a crisis situation, the quality and level of
preparedness make the difference between chaos
and an efficient response.

Security Management in the Water Supply Why ?
? Pressure drops or interruption of water
distribution may rapidly lead to sanitation
problems and degradation of daily life fire
fighting is also a major issue.
? Ingestion, contact or breathing of
inappropriate water may result in diseases and
could cause death.
Whenever a drinking water supply service has
suffered interruption of distribution, or
insufficient pressure, or bad water quality
  • Water utilities will be held responsible
  • for their lack of anticipation,
  • for their lack of preparation,
  • for their inappropriate or insufficient
    reaction.

Security Management in the Water Supply what
risks?
  • Water supply activity related risks
  • pollutions, breaks, backflow….  part of the
    job 
  • Indirect risks as a result of interdependency
  • interruption of power supply, communications, …
  • delivery failure of reagents,
  • transportation strikes…
  • Natural Hazards
  • depending on location and more or less
    predictable,
  • potentially high level of damages to the
    infrastructure.
  • Health risks
  • SRAS, Pandemic diseases.
  • Terrorism
  • in a dangerous world, water supply is a
    potential target.

About the Risks
  • For natural hazards that have already been
    recorded in the past in the same region, the
    question is not  IF , but  WHEN  it will come
    again.
  • The risks vary from immediate effect to longer
    time to fully expand
  • earthquakes minutes
  • floods days
  • droughts weeks
  • man made threats ?
  • The concentration of human population and
    economic activity in urban centers raises the
    level of risks.

5/16

Man made threats what has changed ?
  • Matters of security are now definitely part of
    the job.
  • New relationships are being deployed between the
    water utilities and the authorities.
  • New challenges appear with new constraints but
    also with new opportunities to improve the water
    supply security.

Questions
  • How can the water supplier be prepared against a
    situation he has never met before ?
  • Natural catastrophe or terrorist risk are beyond
    the water utilitys grasp we cant protect
    against everything. What is the limit ?
  • What is the appropriate time scale to take into
    account for the sizing of protection means?
  • When does the involvement of the authorities
    starts ?
  • Who is in charge with what ?
  • What protection for what cost ?
  • How the new technologies can help ?

7/16

Some Answers
  • Water supply is a continuous activity. We need
    to be ready for crisis happening at any time.
  • We all have a probability of roughly 0.4 to face
    a centennial event during our working life.
  • Looking always at how to reduce the risks as
    part of any operational choice is a best practice.
  • There is bad luck, but there is much more bad
    preparedness.
  • The minimum level of security for a defined risk
    is often given by the populations awareness of
    this risk.
  • Training with exercises can be a stress reducer
    when faced to a real situation.

More Thoughts
? Utilities were until recently used to dealing
with  regular  water supply problems, but not
with security matters for which the notion of
risk has been re-evaluated since 9/11 to a
tremendously and unforeseen higher level never
reached before.
? For this reason, they cant afford spending
time on a self learning process for water supply
security we need to learn from each others.
  • Thankfully, crisis on urban water supply are not
    frequent on the other
  • hand, sharing of information on those
    incidents is not easy.
  • ? To a certain extend, the way to react when
  • the resource is unavailable,
  • the treatment process is not operational,
  • the pipe network is down…
  • is the same whatever the reason is.

Risk Management and Security Level
Water Utility
Risk Management
Local level
Constraints Requirements Demands
Regional level
National level
Risk management never leads to 100 security or
zero risks. It just helps water suppliers to know
at what level they are and if this level fits
with their goals.

A new Specialist Group on W2SM
After the last IWA World Congress in Marrakech
2004, Paul Reiter and Michael Rouse expressed
their wish to see a new Specialist Group launched
on Security and Safety Management issues.
This Specialist Group has been created in 2006.
The first committee meeting of the Water Security
and Safety Management Specialist Group was held
today a few hours ago.

What will the W2SM Specialist Group work on?
Best Practices ? define measures to be taken
in order to ensure continuous drinking water
supply and waste water operation.
  • Management of crisis situations in the water
    supply
  • create an international database on water
    related or water concerned crisis situations and
    to record the lessons learned.
  • use the IWA International Network to provide
    links and be used as a reservoir of experts ready
    to offer online help and advice in water issues
    whenever and wherever it is needed. The W2SM
    specialist group will offer its help in setting
    up and organizing this response.

RD ? keep up to date and informed on recent RD
and new technologies in the field of Water
Security and Safety Management and their in site
testing reported by group members.
From the various cultural viewpoints within the
framework of the IWA, different approaches and
experiences are expected to emerge from
discussions and group work.

Major Consumers Initiative Why ?
? The standards for normal operation of the water
systems vary from a country to another or from a
city to another but generally speaking, they are
known in terms of pressure, availability,
quantity and quality.
? Under crisis situations, the normal standards
for water supply wont be attained. There are
many possible levels of degradation of the
service from lower pressure, lower quality or
just lack of any water.
? This being said, what are the consequences of
the degradation of the water service for the end
user ?
14/16

Some Examples
  • The Domestic Users
  • They need water in quantity, but possibly of poor
    quality if boiling ensures that there is no
    health consequences.
  • The bakers
  • If they cannot cook their breads, the local life
    of the neighborhood will be significantly
    impacted !
  • But bakers use water during nights more than
    during days…
  • Health Centers
  • An hospital needs access, power supply and water
    supply in order to be able to operate. If one of
    these elements lacks, the hospital has to be
    evacuated.
  • Is there a need to work hard for water supply
    restoration whenever for example power supply
    cannot be restored yet ?
  • Industrial users
  • Their use of water depends on their industrial
    process, for which low pressure or low quality
    may not be temporarily unbearable.

15/16
17
The Major Consumer Initiative
In their efforts to restore the water supply that
has been impacted, the utilities have to make
choices and to define priorities for action.
The response management under crisis situation
should aim at lowering the effects of the crisis
on the end-user.
In order to be more efficient, we need to know
better the consequences of any possible
degradation of the water supply service for the
customer.
It is easier to start with the Major Consumers…
