Title: Integrated Water Resources Management and Water Safety Plans


1
  • Integrated Water Resources Management and Water
    Safety Plans
  • Are there any links?

Dr Rainer E. Enderlein Regional expert, UNECE,
Geneva

  • Acknowledgment
  • The following presentation uses pictures and
    graphs kindly prepared by my colleagues from
    DHI/Denmark and WHO/EURO graphs from the WHO
    publication on water safety plans and a lecture
    from New Zealand, downloaded from the Internet

  • IWRM is a process,
  • which promotes the coordinated development and
    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
  • (GWP, 2004)

4
  • Implementing an IWRM process is a question of
    getting three pillars right (GWP, 2004)
  • moving towards an enabling environment
    (policies, strategies and legislation for
    sustainable water resources management,
  • putting in place the institutional framework
    (to implement the policies, strategies and
    legislation),
  • setting up the management instruments (required
    by the institutions to do their job)

11
IWRM importance for water supply and sanitation
  • Water management policies, strategies and
    legislation also comprise water use for drinking
    water and discharge of waste water
  • Water-quality standards and pollution charges are
    part of the legislation
  • Monitoring of surface waters and groundwater as
    well as source water quality

12
By the time monitoring shows that drinking-water
maybe / is microbiologically contaminated many
people may have been infected (in some cases
fatally).

  • Two principal concepts
  • Product Quality Control (QC) monitors compliance
    with standards
  • QC tells us that something has gone wrong after
    it had happened.

  • Two principal concepts
  • Product Quality Control (QC) monitors compliance
    with standards
  • QC tells us that something has gone wrong after
    it had happened.
  • Process Quality Assurance (QA) uses risk
    management
  • QA tries to stop that something is going wrong.

21
  • Water Safety Plans are a major Quality Assurance
    (QA) tool for drinking water quality management

22
  • Water safety plan
  • The objectives of a water safety plan are to
    ensure safe drinking-water through good water
    supply practice to
  • Prevent contamination of source waters
  • Treat the water to reduce or remove
    contamination to the extent necessary to meet the
    water quality targets and
  • Prevent re-contamination during storage,
    distribution and handling of drinking-water.

23
  • What are the hazards ?
  • What events could occur ?
  • What could be their effect on public health?

24
HAZARD
CONSEQUENCE
EVENT
Chlorinator fails
People are sick
E. Coli
25
  • For each event
  • How severe would the public health consequences
    be? Severity
  • How likely is the event to happen ? Frequency

27
  • Decide the order of priority for managing each
    risk use a benefit/cost approach
  • Decide the order in which to make improvements
  • Develop a programme for managing the risks

28
  • Prepare an improvement schedule, taking into
    account the available resource
  • Define the responsibilities for implementing the
    plan
  • Specify a date for reviewing the plan

29
  • The WSP is one of the sets of drinking water
    quality management tools available to regulators
    and suppliers.
  • The use of the WSP and IWRM tools should be
    integrated, so that they combine to function as a
    mutually supporting system.
