The Durban Metropolitan Area's (DMA) freshwater issues are being managed
through national and local policies and Durban Metro Water
Services programmes. At a local level, the Durban Metropolitan
Environmental Policy Initiative sets out policy statements
and implementation strategies for the sustainable use
of freshwater resources. This is supported by initiatives by
Durban Metro Water Services to plan for Durban's future water needs
and manage waste water.
Durban's water supply and demand management
plan
Durban Metro Water Services has developed a strategy plan for the
DMA's future water needs. A number of initiatives are underway to
ensure that the DMA has an adequate water supply to
meet future water demands. One of the larger projects planned for
the year 2007 is the drawing of approximately 300
megalitres of water a day from the Umlaas Road Reservoir. This
will supply the Outer West and Inner West Local Councils.
Associated with this proposal is the development of the Jackson
Falls Reservoir which will have the capacity to store
approximately 200 megalitres of water. Other projects include
the construction of the Hammersdale Reservoir, which is
currently underway and 3 additional reservoirs in the Inanda
area within the next 3-4 years.
In parallel to initiatives to address the water supply issue
are efforts to decrease water demand in the Durban Metropolitan
Area. Durban Metro Water Services aims to decrease water
loss to zero growth for the next four years. Projects are
being successfully undertaken in Kwa Mashu and Umlazi to
decrease water loss. Problems such as taps left running
unnecessarily and leaks are being addressed by installing
meters, and putting pipelines under the roads, for easier
monitoring access.
Plans are also in place to begin water recycling. Durban Metro
Wastewater Management Department have negotiated a private concession to
construct a water recycling plant. It is envisaged that the
plant will recycle approximately 47 megalitres of water per
day. The water, which will be of good quality, will be sold to
industries in the Durban South Industrial Basin. The
construction phase of the project will begin in the near
future and it is expected that the plant will be operational
in approximately 14 months.
In addition, the DMA has initiated an
innovative pricing policy for water consumption and waste
water discharge. The price you pay for water depends on
the quantity used - the more you use, the more you pay per
kilolitre. This promotes the wise use of the water resource
and reduces water wastage.
Liquid waste management
Durban Metro Water
manages industrial effluent by permitting and regulatory
policies. It also carries out a routine chemical and
bacteriological monitoring programme of river water to ensure
the operational efficiency of the entire sewerage system. This
also includes detecting sewage leakages and identifying
pollution 'hotspots' where malpractices by industry
occur.
New national legislation
The National Water Act
36 of 1998 provides for the management of water
resources in accordance with a wide range of ecological,
social and economic factors. It provides for the establishment
of catchment management agencies to manage water resources on
a regional basis. Local authorities will be represented
(either directly or indirectly) on the board of the relevant
catchment management agency. This will provide an opportunity
for the Durban Metropolitan Council to become actively
involved in the management of catchments, both those within
the metropolitan area, and more importantly those extending
outside the city boundaries upon which the Metro depends for
its supply of potable and industrial water.
Durban Metropolitan Environmental Policy
Initiative
An Environmental
Management Policy has been prepared for the Durban
Metropolitan Area. Objective E3 addresses the management of
water resources.
|
Objective E3 : To manage water
resources in an integrated manner in order to provide
for basic human needs, for the minimum flow requirements
of water systems and for economic activity, on a
sustainable basis. |

Policy statements
- A water resource management
policy for the DMA shall be developed by relevant
stakeholders.
- Local government shall
continue to improve the effectiveness of its water
demand management programme.
- Integrated catchment planning
and management shall be carried out for catchment
areas in the DMA and its hinterland, including those
supplying the DMA or affected by it, in collaboration
with relevant stakeholders.
- Local government shall
participate in the process initiated by the Department
of Water Affairs and Forestry to establish catchment
management agencies for catchments within, and
supplying, the DMA with freshwater.
- Local government shall link
natural resource management within the DMA to
initiatives in the hinterland of the DMA through a
system of sub-catchment fora, catchment management
committees and catchment management agencies.
- Water quality and quantity
shall be planned for and managed in order to achieve
the desired future state for each freshwater system.
- Ecological services provided by rivers, wetlands
and the ocean shall be protected, with the assistance
of all users.

Possible implementation strategies
- Establishment and review of
desired future state of all water systems.
- Investigation of flood
protection measures other than hard engineering
solutions (ie channelisation and canalisation)
- Water attenuation measures to
lessen increasing flood levels from urban run-off from
impermeable surfaces.
- Removal of alien invasive
vegetation from river catchment areas.
- Investigating alternative
water supply sources to the construction of large
dams.
- Maintaining and upgrading
water reticulation systems.
- Collection of rainwater from
roofs.
- Investigating systems for
reuse of different qualities of water, including
'greywater'.
- Water recycling schemes.
- Encouraging the use of water
saving devices in existing, new and upgraded
developments.
- Land-use planning instruments
to control water demand and water quality.
- Pricing of water to manage
demand.
- Industry, school and adult education on water
conservation.
