WATER and
Sanitation Minister Pemmy Majodina, on 25 October commissioned the newly
upgraded Hazelmere Dam. The commissioning of the dam comes after the Department
of Water and Sanitation completed a project to raise the dam wall by seven
metres to increase capacity of storage as well as augment water supply to areas
such as Verulam, Groutville, Blythedale, and Ballito.
Minister
Majodina said the North Coast has experienced rapid growth in recent years,
especially in the housing sector which resulted in an increased demand for
potable water. “The Department of Water and Sanitation upgraded the Hazelmere
Dam wall to meet the needs of the increasing population in the North Coast as
it is our role to ensure bulk water supply. The concerned municipalities should
now roll up their sleeves to ensure that water is directed to households,” said
Minister Majodina.
The project
scope of the work entailed the raising of the dam wall from 86 metres to 93
meters. This included the construction of retrofitting a Piano Key Weir (PKW)
onto an existing dam spillway structure, the installation of 83 rock anchors,
as well as foundation grouting and other minor related works.
Minister
Majodina expressed that the Hazelmere Dam forms part of the country’s state-of-the-art
dams. “The Hazelmere Dam can now be measured against world-class standards due
the type of spillway selection, technology, and innovation used in implementing
the project,” she said.
The dam has
an uncontrolled PKW spillway, this was done to ensure that the dam wall
withstands extreme concentration of floods of between six and eight hours for
the dam catchment area.
Some of the
employed technologies undertaken to upgrade the dam wall included the world’s
highest PKW, the world’s largest anchors were installed to improve stability of
the concrete gravity dam wall structure, and the largest capacity
post-tensioning stressing jacks were deployed during construction. Some of the
technologies employed included the use of innovative data management software
for real-time monitoring of anchor performance, and 3D digital crack meters.

The Municipality commissioned five boreholes recently
in areas experiencing water supply challenges.
The boreholes were commissioned in Ward 60, Mhlasini
area 2 in Verulam, Ward 100 in uMlazi V-Section and the Nwabi area, and Ward 98
in Nkwali Mahagana and Mgobhozini.
These communities will no longer rely on the tankers for
their water supply as the boreholes are in the communities as part of interim
relief.
Ward 60 Councillor Fakazi Mdletshe expressed gratitude
and said the borehole will go a long way in mitigating the water supply
challenge in the area.
“We appreciate having a borehole in the Mhlasini area
because relying on water tankers is not sustainable as these trucks do not come
to the area every day. The Mhlasini area has grown rapidly with many households
and residents. This resulted to the water bulk line not having capacity to meet
the growing demand. There is not enough pressure to push water to this area;
however, this is being attended to through infrastructure upgrade,” said Councillor
Fakazi.
The borehole produces 2 000 litres a day and can run up to 20
hours a day. Water
produced from the borehole has been tested and complies with the South African
National Standard 241 for drinking water requirements.
Residents are discouraged from washing their
cars, clothes, and connecting hosepipes to and from the borehole taps to their
household static tanks.
“I urge residents to look after this borehole
as it has been installed for their benefit. I hope I will not hear any reports
of the theft of taps and other components as this will be a setback for
residents who rely on this water. Also, the water must be shared equitably,” he
said.
