The construction of phase 1 of
Madibeng water purification plant,
in South Africa, is set for completion
in 2019.
Water and Sanitation Minister
Gugile Nkwinti confirmed the
reports and says that the total
estimated cost for completion
of the first phase is about
USD40-million, while the estimated
cost of the second phase is
approximately USD52-million.
Madibeng Local Municipality
owns and operates two water
treatment works, treating a
combined capacity of 70Mℓ a day.
Water supply is also augmented by
the boreholes and Rand Water with
capacity of 35Mℓ a day.
Water is abstracted from
Hartbeespoort Dam and it uses
a conventional water treatment
process that includes coagulation,
flocculation, dissolved air floatation,
filtration, and disinfection. The
municipality operates a total of 33
sewer pump stations and four water
booster pumps. u

Phase 1 Madibeng water plant due in 2019

Old Mutual’s new Water Filtration Plant
at its Mutualpark office in Pinelands
has gone off the City of Cape Town’s
water grid. As the first corporate-based
waste-to-drinking-water filtration facility
in South Africa, this means that the
166  000m² office, accommodating more
than 9  000 employees and contractors, is
now officially operating off the grid.
Employees consume about 450 000 litres
of water a day at Mutualpark and the new
plant can produce between 650  000 and
800 000 litres a day, which will save the city
10 000 to 15 000 kilolitres of water a month,
making the office self-sufficient and
independent of the regional water grid.
Old Mutual’s chief operating officer, Iain
Williamson, said before the installation
of the plant, the firm had implemented
water-saving initiatives and reduced
consumption at Mutualpark by about 30%.
“By driving mutually beneficial
projects, Old Mutual creates shared
value. A project like this, which is both
cost-effective and responsibly geared to
ensuring a sustainable future, is a win-
win for all,” Williamson said. u

The provincial government of Western
Cape announced that all three Cape
Town desalination plants are now
online and are producing a collective
eight million litres of water a day.
Despite delays due to multiple
complications,
the
Monwabisi,
Strandfontein, and V&A Waterfront
desalination
plants
are
now
complementing the City of Cape Town’s
strained water supply system. With dam
levels now sitting at 56.9% following a
marginal increase of around 0.5%, the
timing of the additional eight million
litres couldn’t have come at a better
time.
In light of the National Department
of Water and Sanitation’s failure to
augment water supply infrastructure in
the Metro, the City of Cape Town has
had to construct its own bulk water
supply infrastructure. This is where
money accrued from water tariff
increases is being spent — to prevent
a drought from ever returning to the
Western Cape.
In addition, continued water-saving
efforts by Cape Town residents are also
paying off. The deputy mayor, Alderman
Ian Neilson, revealed that the City’s

average water consumption remains
below the 500-million-litre threshold.
“I commend all the residents
who continue to comply with water
restrictions as a means of preserving
the City’s precious water resources.
I furthermore commend the staff of
the City of Cape Town for their hard
work and unwavering commitment to
ensuring Cape Town’s taps don’t run
dry,” he says. u
