Introduction
  • Water is a vital natural resource because it is
    fundamental to life. Although it is a key
    indispensable natural resource, water in South
    Africa is very scarce.
  • Water in South Africa is being transferred over
    long distances on very large scales which means
    the performance of all water providers should be
    monitored and improved.
  • The NWA, 1998 is founded on the central
    principles of equity, efficiency and
    sustainability.

Extent of Water Losses and Wastages NRW
Non-Revenue Water refers to the total of apparent
losses, real losses and the proportion of
authorised consumption, which is not billed.

Non-Revenue Water refers to the total of
apparent, real losses and the proportion of
authorised consumption, which is not billed
  • 390 million m3 of water lost through Non-Revenue
    Water is a massively huge amount of water FAR IN
    EXCESS OF THE NEXT AUGMENTATION SCHEME FROM
    LESOTHO _at_ R15billion.

Causes of the water losses and wastages
  • Lack of dedicated financial resources to support
    implementation of water conservation and demand
    management interventions including O and M.
  • Lack of institutional commitment and regulatory
    tools to enforce implementation of WC/WDM as per
    the NWA, 1998 and the WC/WDM Strategies resulting
    in
  • Old dilapidated infrastructure (physical
    leakages),
  • Institutional capacity (billing systems and
    auditing),
  • Education and awareness (consumer behaviour to
    water),
  • Political leadership at provincial and local
    level (technical managers complain of not getting
    support to implement with budgets being reduced
    or not availed for WC/WDM).

27
Work In Progress Institutional Interventions
  • Institutionalising WC/WDM through regional office
    structure
  • Developing protocols governance tools for
    WC/WDM
  • WC/WDM conditions for WUA,
  • WC/WDM sector Guidelines,
  • WC/WDM Training Manuals,
  • WC/WDM Info. System,
  • WC/WDM Regulations.

28
Work In Progress Implementation Support
WMA situation assessment studies
  • Developing WC/WDM Strategies and implementation
    plans for the following WMAs in support of Water
    Allocation Reform
  • Olifants WMA (Mpumalanga and Limpopo),
  • Inkomati WMA (Mpumalanga),
  • Mvoti-Mzimkhulu WMA (Kwa-Zulu Natal),
  • Uthukela WMA (Kwa-Zulu Natal),
  • Usuthu-Mhlathuze WMA (Kwa-Zulu Natal), and
  • Upper and Middle Vaal WMAs,
  • Mokolo Catchment.

29
Work In Progress Implementation Support
Municipal support interventions
  • Providing support (financial and technical) to
    municipalities to develop and implement water
    conservation and water demand management viz.
  • Emfuleni (Gauteng),
  • Umkhanyakude, Uthungulu and Zululand Districts
    (Kwa-Zulu Natal),
  • Nelson Mandela and Buffalo City (Eastern Cape),
  • Ramotshere Moiloa, Rustenburg (North West),
  • City of Johannesburg, Tshwane, Ekurhuleni,
    Sedibeng, Dr JS Moroka, etc (Gauteng/Mpumalanga),
    and
  • Matjhabeng, Moqhaka LM (Free State),
  • Lephalale, Greater Tzaneen, Capricon, Sekhukhune
    DM (Limpopo).

Scope for water conservation and Demand
Management
Where can savings be made ?(addressing only the
wastage and not the billed and paid for
consumption)
31
Recommended Interventions and Work in Progress
  • Develop National Regulations for WC/WDM to
    address amongst others the
  • Setting of national water use efficiency
    standards,
  • Setting of national, provincial and local
    specifications for housing developments with
    respect to water efficient plumbing devices,
  • National labelling of water efficient devices,
  • Enforcement of WC/WDM through provincial
    legislation local bylaws,
  • Setting penalties for wasteful use of water
    within public buildings,
  • Provision of incentives for achieving WC/WDM
    targets and benchmarks.
  • The Department is already in process of
    developing these regulations

32
Recommended Interventions and Work in Progress
  • Establishment of a National Water Demand
    Revolving Fund to support water conservation and
    demand management programmes
  • Australia, USA, and other efficient countries
    have such dedicated funds in place for
    facilitating uptake of WC/WDM.
  • In SA Eskom is piloting an excellent similar
    initiative through its Demand Side Management
    (DSM) Fund for energy efficiency.
  • Discussions are ongoing with institutions such as
    TCTA to explore possibilities for funding WC/WDM
    interventions at a reasonable tariff recovery
    rate.

33
Recommended Interventions and Work in Progress
Backlog of Maintenance before which certain WDM
measures cannot be implemented
Other WDM Interventions
Quick fix WDM interventions
Indirect WDM measures
Valve maintenance and repair, Pipe
replacement Bulk Meter replacement Domestic
meter replacement Replacement and repair of
water towers etc
Full sectorising Proper billing and cost
recovery MIS and analysis of Minimum Night flows
etc Certain Bylaws
Pressure management Leak location
Repair Manage impact of inefficient garden
irrigation etc
Schools awareness Public Awareness CLOs door
to door discussions
Billing and Payment for water
34
Return on Investment on Water Conservation and
Water Demand Management (Municipal Revenue)
  • Emfuleni Local Municipality we invested R8m in
    WDM and we are saving in excess of 9million cubic
    metres of water and well over R24m per annum to
    the municipality
  • City of Johannesburg through Operation Qcina
    Amanzi invested has invested R 600 million over a
    period of five years to save 60 million of water
    which would have cost new infrastructure scheme
    of over R 5 billion.
  • In Vaal River System we can invest an estimated
    R3billion on WC/WDM to make available to save in
    excess of R15billion worth of augmentation scheme
    either from Lesotho or Thukela

36
Return on Investment on Water Conservation and
Water Demand Management
  • Create an informed public regarding WC/WDM
  • Create the culture of WC/WDM through water use
    institutions
  • Promote and enforce water wise behaviour
  • Capacitate water utilities and institutions on
    WC/WDM
  • Improve service delivery
  • Address socio economic development of local
    communities through job creation
