Ambitions for Africa
The speed and magnitude of Africa’s ongoing urbanization, with 1.3 billion people expected to
live in cities in 2050 compared to 480 million today, combined with its rapid industrialization,
has shed a new light on the evolving and multifaceted needs for water treatment
infrastructures. To address the plurality of these needs, Veolia Water Technologies has defined
and implemented over the past year a dedicated project called “Ambitions for Africa” which
rests on 3 pillars specific to the African continent.
The first of these pillars was to invest in a brand new chemical plant to blend water treatment
chemicals in Johannesburg, South Africa. This state-of-the-art plant employs 40 people and has
a maximal capacity to produce 15,000 tons of water treatment chemicals each year, which will
allow to address the demand for quality water treatment from municipalities and industrials
throughout the continent. The plant recycles 100% of its wastewater and abids by the latest
environmental rules and regulations in place.
The second major pillar of our “Ambitions for Africa” strategy is capitalizing on our standard
equipment range which has been produced at our manufacturing plant, also in Johannesburg,
for the past 15 years. These robuste, easy-to-operate, low-energy packaged plants are designed
to be deployed in remote locations or in harsh climates and have proven their efficiency in
numerous references across Southern Africa. Veolia Water Technologies is now developing new
models rendered possible through the emergence of off-grid and digital solutions which are
revolutionizing the energy market in Africa.
The third pillar of our “Ambitions for Africa” is to be strongly anchored in the markets where
we are developing projects through local partners who bring us the invaluable knowledge and
competencies required to adapt and properly respond to the challenges of each country.
Attesting to this strategy, South African company Ceracure has become stakeholder in our
South-African subsidiary. This key partner brings not only its expertise in its own field of control
and electrical instrumentation, but also reinforces the company’s compliance with the new
“Black Economy Empowerment” regulations.
In the same spirit, we have established an
ambitious partnership with Afric Chimie under a
joint venture for the distribution of our chemical
products in Morocco which now completes our
solutions offering in Morocco. Combining our own
expertise in water treatment to that of a major
player in the chemical market in Morocco allows
us to offer our range of water treatment chemicals
to municipalities and industrials. Partnerships in
Algeria and Kenya are also in the works.
The “Ambitions for Africa” project is carried out by
our 1,000 employees across Africa. They constitute
the vital link between all local stakeholders to
contribute to an inclusive and long-lasting African
wealth.

4 WAVE I JUNE 2018
THE CONSTRUCTIONThe construction of a new chemical blending
facility started as a serious discussion in 2016.
The decision for a new facility was based on
space constraints experienced at the historical
facility that Veolia Water Technologies (VWT)
South Africa had been operating since 1999.
The selection process of a developer and
site started in February 2017 and the final
selection in July 2017, with Improvon (Pty) Ltd
being selected as the developer and the lease
agreement being signed on 17 August 2017.
Construction started on 28 September 2017,
following the approval of the building plans
by the local council. Final occupation of the
building took place on 20 April 2018. During the
165 days of the construction, 43 subcontractors
were employed to deliver the brand new facility
with exceptional safety statistics:
Near Miss Incidents: 0
First Aid Incidents: 0
Lost Time Injuries: 0
Fatalities: 0
STATE OF THE ART BLENDING FACILITY WITH HIGH ENVIRONMENTAL STANDARDSThe new 6,630 m² building is fully ASIB*
compliant with separate flammable stores.
Overhead sprinkler mains with in-rack
sprinklers and a fully integrated foam
protection system have been installed to cater
for the type of materials stored. The design
also included for a separate flammable store,
truck wash facility and a bunded area for bulk
storage tanks and effluent plant.
The design of the production facility focused
on the following aspects:
• Increased safety for staff with reduced, safer
raw material handling
• Reduced air pollution
• Segregation of reactive chemicals
• Increased production capacity & workflow
improvements
• Zero Effluent Discharge
The new chemical facility has a production
capacity of between 900 and 1,000 tons per
month. Used for the blending of Veolia’s
Hydrex® range of chemicals, it will become the
main blending facility for business in South
Africa as well as the bulk of the export business
into the rest of Africa, which forms part of
Veolia’s Ambitions for Africa plan.

Manufacture & Supply 4 Diesel Truck Mounted Mobile Water Treatment Plants
The kingdom of Lesotho counts 2.3 million people and has one of the
lowest density of population. Moreover, the country is very mountainous
which makes it difficult for the government to rely on a fixed network to
provide drinking water through the country. A mobile solution capable
of taking advantage of abundant surface water to provide drinking wa-
ter in remote locations was more appropriate.
Challenges
The main challenge was to develop and design a solution, versatile and
robust enough, to be able to adapt to various types of surface water and
deliver the same water quality in the end. Also, the integration of the
treatment solution onto a 4x4 truck chassis was a technical challenge to
be overcome.
The solution
VWT South Africa developed a Drinking Water plant mounted on a 4x4
truck. The Lesotho government was so much convinced by the solution
that they bought 4 of them. They were delivered between April 2017 and
February 2018.
Water source
Any type of surface water can be used to produce Drinking water
through the MWTP truck due to its versatility. Lakes, Rivers, Dams, can
now be a source for drinking water production delivered directly to the
population.

Our reverse osmosis process involves passing
screened and filtered sea water through semi-
permeable membranes at very high pressure.
This causes the salt to stay behind, while
pushing through desalinated water on the
other side. The concentrate (brine) produced
is sent to a dedicated brine tank.
Energy recovery systems help save electricity
whilst backwash water and brine are stored
before being slowly released back into the
ocean.

CASE STUDY
AQUAVISTA™
for a soft drink manufacturer,in AfricaPortal, Insight & Assist
Food and Beverage companies currently face
several challenges with water management,
which is especially true concerning ingredient
water used in the actual product. It is a
key challenge to monitor in real-time the
quality of their ingredient water in order
to ensure the maximum traceability of the
production processes to ensure compliance to
increasingly stricter regulations.
Project ScopeIn September 2015, a 100m/h water
treatment plant for a global beverage leader
was installed in North Africa. The solution
implemented is BERKEFELD PurBev®, a range
of hygienic water treatment solutions for
the food & beverage industries consisting
of reverse osmosis, activated carbon
and ultrafiltration technologies. This
beverage company was looking for a way
to considerably improve the monitoring of
their ingredient water. One of the client’s
main objectives was to improve their water
consumption KPI liter to liter.
The ProblemDuring operation the performance of both
ultrafiltration units had severely and abruptly
declined. Discussions, analysis and various
counter measures such as CIP procedures
on site had been carried out without
sustainably solving the problem. Since a
further degradation of the UF performance
would have lead to a shutdown of the plant
causing considerable damages and costs,
an action plan was defined by Veolia Water
Technologies engineers. The main objectives:
• Determination of root causes of rapid
differential pressure increase
• Reduction of the differential pressure of the
UF systems by performing modified CIP
• Inspection of the dosing equipment and
dosing rates
• Check of chemical quality and concentration
The ActionAs Aquavista Portal, Insight and Assist was
implemented, process experts were able
to investigate the causes based on the
available data and trends from the previous
months and to suggest counter actions
in a timely manner. The Aquavista digital
services modules provided are Portal, Insight
and Assist. The Aquavista Services has
successfully allowed the company to closely
monitor their ingredient water in real-time
by monitoring the parameters of PurBev, with
an ATAWAD (AnyTime, AnyWhere, Any Device)
access to this information.
AQUAVISTA Key Features:• Remote monitoring of parameters
• Remote control on demand
• Operations reporting

Client Benefits
The introduction of digital services in the
water treatment plant at this production
site has provided technical and operational
benefits for the client. Their processes and
plant is now more reliable and they were able
to reduce their operating costs.
They are able to now fully access real-time
data on their ingredient water and monitor
the quality of it according to the regulations,
and more importantly, to their specifications.
A full team of Veolia experts are in charge of
analysing the reports generated from the KPIs
and send out immediate feedback in case
of any problem. These experts also provide
recommendations and advice on how to
improve operations.
The client benefits from more process support
and expertise to operate the water treatment
plant, as well as from high value digital services.
“We are very satisfied with the new Veolia
performance monitoring service. This really
is a high value service which helps us to
reduce operational cost and improve the
reliability of our water treatment plant.
Veolia’s digitaliation strategy is the right
step to differentiate its services further from
competition” engineering director, April 2017.
This project has not only allowed for the client
to benefit from increased reliability but also
from increased plant uptime and an overall
improvement in performance. The client
feedback and testing has allowed us at Veolia
to considerably improve our technologies,
services and the PurBev design. ●

FOCUS
Water reusea safe and sustainable water supply
During the 20th century, the demographic
explosion and economic development
caused water consumption worldwide to
increase by 800%. In parallel, under the effect
of climate change, droughts have become
more frequent and more serious in many
regions. It is therefore crucial to develop local
solutions that preserve water resources.
The world has to rethink its relationship
with resources and come up with new social
and economic growth models that are
more efficient, better balanced and more
sustainable.
Water is a renewable resource, but it is very
unequally distributed and increasingly scarce
as a result of urbanization and climate
change: by 2030, nearly half the world’s
population will be living under conditions of
severe water stress.
A comprehensive suite of solutions exists to
respond to these challenges, ranging from
integrated water resource management
to wastewater reuse. Today, less than 5%
of all water is reused globally, but recycled
wastewater is the only resource that grows
with the needs.
Reusing wastewater increases the
productivity of the abstracted water, for
instance in agriculture where it allows to
grow ‘more crops per drop’. Reusing water
may also mean mining waste and turning it
into a new source of materials or energy as
is the case with the methanization of waste
and wastewater streams from the food &
beverage industry, or the material recovery
out of mining industry wastewater.
Drawing upon its worldwide experience
in water cycle management, Veolia Water
Technologies has developed standard
solutions for water recycling and reuse.
There is not a single specific technology for
water reuse; it is very often obtained after
association of several processes/technologies
applied to each specific case such as
clarification, reverse osmosis, evaporation and
chemical treatment.
In most industries, such as Metals & Mining,
Pulp & Paper, Power, Food & Beverage and Oil
& Gas, the high volumes of water used during
the overall manufacturing process represent
a significant expense. In many forward-
thinking companies and municipalities,
water reuse systems are already in place,
allowing these users to enjoy a guaranteed
availability of water supply; substantially
lower their water bill; supplement their
profitability by harvesting valuable resources
contained in wastewater; and practice
more environmentally sound water usage
operations.
Water reuse can take a variety of different
shapes and be achieved at any volume, as
required by customer applications. Veolia
Water Technologies, backed by a leading
portfolio of high-efficiency, low-footprint
treatment technologies, is able to treat even
the dirtiest, polluted wastewater to potable
and even ultrapure standards. ●

Some referencesfor water reuse in Africa
At the world-renowned
Goreangab Water Reclamation
Plant in Windhoek, Namibia, Veolia
Water Technologies has been actively
involved in treating wastewater and
semi-purified sewage to a potable
standard since 2001. In an arid region
that lacks adequate conventional
water sources, this plant plays a
critical role in allowing Windhoek
to be a modern, sustainable city,
supplying over 21 Ml/day (+/- one
third of the city’s total potable water
supply).
Wastewater doesn’t have to be
treated to a potable standard in
order to fulfil a valuable role in
water supply security. At the Durban
Water Recycling (DWR) Plant for
example, 47.5 Ml/day of domestic
and industrial wastewater is treated
to a standard ideal for process water
by industrial users such as Mondi
Paper and SAPREF. For industry, a
lower per-unit cost for process water
increases profitability, while the city
is able to free up bulk water supply
for a growing urban population,
thereby reducing immediate capital
investment requirements, while also
reducing pollution load on Durban’s
local marine environment.
Direct, on-site, private water reuse
systems can also be implemented.
Ambatovy Mine in Madagascar, for
example, recycles its process water
ad infinitum, achieving Zero Liquid
Discharge, while harvesting around
210,000 tons of ammonium sulphate
contained in the water that it then
sells as a high-quality agricultural
fertiliser as a secondary revenue
stream.
In Morocco, Renault’s plant in Tanger
is another example of achieving Zero
Liquid Discharge: thermal energy
consumption was reduced by 35%
and processes were redesigned
to minimise water use. A water
recirculation loop further reduced
the site water consumption by 70%
and eliminated all industrial liquid
discharges.
These are just a handful of the water
reuse plants supplied by Veolia Water
Technologies in Africa, providing a
broad overview of the possibilities of
water reuse applications.
Across our complete installed base,
Veolia Water Technologies has
provided water reuse solutions for
full potable reuse; facility cooling;
boiler feed water; industrial process
water; irrigation in agriculture
and urban green spaces; and
groundwater storage and recovery.
Success in these applications has
only been possible through having
access to the world’s leading water
reuse and recycling technologies
that Veolia Water Technologies
has developed globally. These
technologies include clarifiers,
softeners, biological aerated filters,
evaporation technologies, discfilters,
RO membranes and chemicals.
That’s why Veolia Water Technologies
is the proud supplier of some of
Africa’s largest and most important
water reuse plants. ●

WATER REUSE CASE STUDY
In Durban, industries run on recycled water
W ater resources are limited
in South Africa, especially
in the City of Durban. To ensure
the city’s residents are given
priority in accessing drinking water
resources, the Durban Recycling
Plant was developed by Veolia
Water Technologies to switch
manufacturing processes to
recycled water. 98% of the city’s
wastewater is recycled, freeing
up 40,000 cubic meters a day for
consumption by citizens.
Commissioned in May 2001, the
plant features some of Veolia Water
Technologies flagship processes
such as the Multiflo™ clarifier and
Hydrex® water treatment chemicals.
Veolia’s scope of work under the
20-year operations & maintenance
contract includes responsibility for
managing the water through the
entire value chain. This incorporates
wastewater catchment, conveyance,
trade effluent control, preliminary
and primary treatment, secondary
and tertiary treatment, reclaimed
water reticulation and utilisation.
The water catchment available to
Durban City is at the limit of its
resource capacity and increased
bulk water supply to the city could
only be undertaken by means
of extremely expensive inter-
catchment transfer schemes. The
Durban Recycling Plant therefore
serves to significantly protect and
ensure the sustainable development
of the City’s existing available
water resources. South Africa is
a water stressed nation and this
project undoubtedly contributes to
the preservation of natural water
resources. In addition, the project
is the first of its kind in South
Africa and may be regarded as a
model for this type of approach to
water resource management in the
country – and the continent.
The drought recently experienced in
parts of South Africa has brought to
the fore the benefits for industry in
using reclaimed water as opposed
to potable water for their process
needs. While all potable water users
had to reduce their off take, those
industries that receive reclaimed
water enjoyed continuous supply
with no restrictions and therefore
did not have to reduce production.
The benefits that can be derived
from switching to a reclaimed water
source from potable water are
therefore both environmental and
financial.
The Durban Recycling Plant
represents an ideal example of a
Public Private Partnership where a
local municipality supplies domestic
and industrial effluent for treatment
to near potable standards and
then distributes it to local industry
for direct reuse in their industrial
processes. In this case, the companies
involved are Mondi and Sapref. ●

Veolia and Renault partner up in TangierT ogether, Renault and Veolia have
constructed the world’s first zero carbon
emission and Zero Liquid Discharge ( ZLD ) car
manufacturing plant.
Working with the Moroccan government
to build sustainable industries, Renault and
Veolia together set out to build the world’s
most sustainable car production plant and
the first with zero carbon emission and zero
industrial liquid discharge. The first approach
involved reducing the facility’s consumption
by leveraging Veolia’s environment expertise
and co-engineering with Renault on the
manufacturing process.
Started up in early 2012, Renault’s plant
in Tangier had an initial yearly production
capacity of 170,000 vehicles which was
extended to 400,000 at the end of 2013.
Renault partnered with Veolia on both the
initial phase and the extension.
Thermal energy consumption was reduced
by 35% and processes were redesigned to
minimize water use. A water recirculation loop
further reduced the site’s water consumption
by 70%, equivalent to 175 olympic swimming
pools, every year, and eliminated all industrial
liquid discharge.
A number of steps are required to transform
the effluent into purified, demineralized water
which can then be reused on the vehicle
production lines. These results have been
achieved by optimizing the manufacturing
processes to reduce the need for water and
the corresponding discharges, and thanks
to the use of leading-edge technologies
developed by Veolia Water Technologies, which
include the Evaled™ evaporator, to recycle all
the industrial effluents.
A sustainable CHP system using renewable
biomass as the primary energy source was
selected to provide the thermal energy
requirement of the site. In total, this measure
eliminated an estimated 135,000 tonnes of
CO2.
Since it came into operation, the Renault plant
in Tangier has become a global benchmark in
terms of environmental excellence. ●

Veolia Water Technologies
executed the electrical design
and mechanical installation of the
ZAR 125 million Ujams industrial
wastewater treatment project near
the City of Windhoek’s northern
industrial zone. The plant was
designed to treat u p to 5,000 m/
day of industrial wastewater for
re-use and irrigation, and is one of
the city’s key water infrastructure
projects aimed at complying
with Namibia’s national water
regulations.
The Ujams Wastewater Treatment
Company, a Special Purpose
Company, contracted Veolia
alongside VA Tech in 2012 to design,
build, install and commission the
wastewater treatment plant. The
Ujams Wastewater Treatment
Company raised finance for the
project and will operate and
maintain the plant for 21 years.
The Ujams wastewater plant
is designed to accommodate
additional effluent from future
industrial developments in the
greater catchment area. This plant
enables reliability, efficiency and
compliance with the country’s
standards for reclaimed water used
for irrigation.
The plant’s incoming wastewater
is screened and de-gritted before
entering the latest-generation MBR
(membrane bio-reactor) system.
Before being released from the
plant, the water is disinfected with
UV treatment, and the various
treatment areas are linked to an
odour removal process.
Improved water for the Elisenheim and Brakwater communitiesThe wastewater treatment
plant replaced the region’s older
UJAMS wastewater treatment
plant, located roughly 20 km
north of Windhoek. Originally
commissioned in 1966, the plant
had gradually become overloaded
with the northern industrial
zone’s expansion. With a large
tannery, a brewery and an abattoir
discharging effluents into the
catchment area, peak flows often
resulted in poor treatment quality,
which caused odours within the
nearby Elisenheim and Brakwater
communities.
The new plant features some
of the water industry’s latest
technologies, and we’re able to
remove high levels of E. coli and
other pathogens, grease and salts,
which will make the water ideal for
re-use as irrigation water. During
the rainy season, when the demand
for irrigation water is low, the high-
grade reclaimed water is discharged
into the Klein Windhoek River,
where it enters the groundwater
system or the Swakoppoort Dam as
a high-quality water stream.
The city’s main drinking water
reclamation system at Goreangab
is a world-first in water re-use by
upgrading municipal sewage for
direct re-use in the city’s potable
water reticulation system. To
protect this system from industrial
inflows, Windhoek’s wastewater
systems have been set up in such
a way that effluents coming from
industrial areas are kept separate
from domestic sewage, and treated
separately. This, as well as the fact
that the Swakoppoort Dam is a
main source of drinking water
for the city, makes the Ujams
plant a critical part of the city’s
infrastructure. ●

Reverse Osmosis units and ensure
that the treated seawater used in
the oil extraction process meets
not only Total’s stringent quality
standards, but conforms to global
standards enforced throughout the
industry. Shipped as 10 containers
“FCL” every month, the 160 ton order
comprises Antiscalants, two CIP
Cleaners, Oxidising Biocides and
Dechlorination chemicals all from
Veolia’s renowned Hydrex® range.
“Over 75% of these chemicals are
produced locally in Isando,” adds van
Niekerk. “What this means for Total is
that by eliminating high import costs,
we are able to offer the chemical order
at a fixed rate for the duration of the
contract – a key factor for the client.
Producing this quantity of chemicals
is well within our capabilities,
and to assist us with storage and
container loading we outsourced to
local specialist freight forwarders
Intraspeed and Hellmann.”
Veolia, using Intraspeed and
Hellmann and its global logistics
partners, will ship the chemicals to
Sonils base in Luanda every four to
six weeks. “Typically chemicals are
shipped every four to six months
to these
operations,
but owing
to our local

ZambiaContribute to better water supply and sanitation
Kafubu Water and Sewerage Company
(KWSC) has entrusted Veolia, through
its subsidiaries Veolia Water Technologies
and Krüger A/S, to rehabilitate and expand
its water and wastewater infrastructures
located in the Copperbelt in northern Zambia.
The USD 101.6 million contract aims at
improving the water and wastewater services
in Ndola, Luanshya and Masaiti urban areas
and strengthening the capacity of KWSC
to operate the facilities in an efficient and
sustainable way.
Situated north of the country, Ndola is the
third largest city in Zambia, the industrial
and commercial center of the Copperbelt,
Zambia’s copper-mining region, and the
capital of Copperbelt Province. It is also the
commercial capital city of Zambia and has
one of the three international airports, others
being Livingstone and Lusaka. It is expected
that by 2020, the inhabitants of the three
urban areas will increase from 600,000 to
900,000 people who will benefit from the
project through improved health conditions
and increased reliability of the water supply
and sanitation services.
The existing water and wastewater facilities
are in a progressive state of physical
deterioration, with 67% of water wasted
through leakage in the distribution network
and sewer overflows which flood streets and
roads, resulting in serious damage to property
as well as health.
The rehabilitation program comprises
approximately 147 km of distribution
networks for drinking water, as well as 21
groundwater wells, 6 raw water intake
installations for surface water, 6 waterworks,
and 18 pumping stations. Furthermore,
the 9 wastewater treatment plants will be
renovated and approximately 30 km of sewer
networks will be upgraded. The project will be
conducted over 30 months and is expected to
be completed by September 2017.
“We are delighted to be working with
Veolia on a project so important for the
sustainable future of our region. We trust
that their experience on both a regional and
international level will contribute to the
success of the project”, said Athanasius K.
Mwaba, Managing Director of KWSC.
Jean-François Nogrette, Chief Executive
Officer of Veolia Water Technologies, said:
“We are very pleased to have been chosen
by Kafubu Water and Sewerage Company
to help it provide for a better access to
essential services. For 160 years, Veolia has
been committed to ensuring that everyone
has a sustainable and qualitative access to
basic water and cleanliness, as well as to
preserving resources. We are looking forward
to our expertise and solutions supporting the
Ndola, Luanshya and Masaiti communities’
wellbeing.”
The project was made possible thanks to
a loan granted by the Danish Government
through its international development agency
Danida Business Finance. It will be executed
by a consortium of Veolia subsidiaries, Krüger
from Denmark and Veolia Water Technologies
in South Africa. ●

Two packaged water treatment plants for
Bambisana HospitalVeolia Water Technologies
South Africa recently assisted
state-owned hospital, Bambisana,
with two standard packaged water
treatment plants. Situated in
remote Eastern Cape, the hospital
required low-footprint and low-
maintenance water treatment
solutions to provide potable
water to the hospital as well as
to treat its sewage water prior
to release in the environment.
Veolia designed, manufactured
and commissioned two of its
trademarked containerised, plug-
and-play standard solutions in just
three months for the hospital.
“Our packaged plant solutions are
a cost-effective alternative to in-
ground plants and are well suited for
remote areas that are situated away
from bulk water infrastructure, such
as with Bambisana hospital,” says
Royston Moses, Project Engineer,
Veolia Water Technologies South
Africa.
Supplying consistent potable waterThe previous reservoir infrastructure
provided an inconsistent supply
of water and was therefore
unsuitable for the hospital that
requires consistent, high-quality
water for its day-to-day operations.
“Furthermore, our water quality
studies indicated that the existing
reservoir and borehole water was
host to low-concentration bacteria,
high turbidity and slight residual
colouring,” comments Royston
Moses. Veolia supplied the hospital
its Potable Water Treatment Plant
(PWTP™) that produces 120 m of
high-quality potable water per day.
The PWTP™ features a clarifier, sand
filter, carbon filter and a range of
chlorine, coagulant, flocculant and
pH dosing equipment, all packaged
in a single container to treat
the water to SANS241 and WHO
standards.
Treating hospital sewageWith no former sewage treatment
infrastructure in place, the hospital
also required a packaged plant
to treat its wastewater according
to the RSA General Standard
for Discharge. Veolia addressed
this with its packaged Sewage
Treatment Plant (STP™) that
upgrades 60 m of sewage water
per day. Enclosed in 6 six-metre
containers, the STP™ features
Veolia’s cost-effective trickling filter
technology to treat the sewage
water to certified discharge and
irrigation re-use standards, as
well as a bar screen, septic tanks,
clarifiers and chlorine-dosing
equipment.
Both plants are fully containerised
to protect the equipment from
environmental impacts and for
a rapid and easy installation. “All
our packaged water treatment
solutions are pre-assembled and
Factory Acceptance Tested at our
workshop in Johannesburg. What
this means for Bambisana hospital is
that the plants simply needed to be
‘plugged-in and switched on’ when
they arrived on site,” adds Royston.
“By lowering manufacturing and
commissioning time, we were able
to supply these cost-effective water
treatment plants in just three
months.”
Although both plants are easy
to operate and require very little
maintenance, Veolia remained
onsite to provide local operator
training. The PWTP™ was delivered
to site in June 2017, closely followed
by the STP™ two weeks later.
Towards a re-use of the treated wastewaterThe treated water coming out of the
standard Sewage Treatment Plant
will be soon used to grow crops as
an agreement between the Hospital
and the community. ●

Veolia Water Technologies installs
Koeberg Nuclear Power Station’s
containerised desalination plantto augment water supply
Veolia Water Technologies South Africa
(Veolia) designed and installed a
containerised desalination plant to treat
borehole water for the Eskom Koeberg
Nuclear Power Station in the Western Cape.
The desalination plant is used to augment
Koeberg’s water supply during the drought
until its permanent desalination plant is
complete.
As a response to the drought in the Western
Cape, Veolia was contracted by the Koeberg
Operation Unit of Eskom Holdings Limited,
to manufacture, commission and install
the containerised desalination plant. The
plant was installed during January 2018,
with fabrication and testing conducted at
Veolia’s Water Techno Packages Worksop
in Sebenza Johannesburg. Teams in South
Africa managed plant installation and
commissioning.
The plant treats 1,317 m/day of groundwater,
sourced from an onsite borehole, to potable
water standards, which is used for boiler feed
water and drinking water. In addition to the
plant’s plug-n-play functionality, an advantage
is its scalability – its capacity can increase
if there is parallel configuration of another
containerised unit. This configuration will be
used when a second containerised desalination
plant of the same capacity is installed and
commissioned onsite in the near future.
Eskom works hand-in-hand with Veolia on
the project ensuring that there is adequate
electrical supply for the plant, and also
supplied the storage tank for produced
permeate, the groundwater (sourced
from onsite boreholes) and all rigging. In
addition to the containerised plants and all
componentry, Veolia supplies all chemicals
and provides support services to ensure
optimum plant operation for the 12-month
rental agreement, which includes operators
and supervisors for plant operation and
maintenance.
“The desalination plant is part of Koeberg’s
three-pronged water management strategy
to address the current water shortages in the
Western Cape while ensuring that the plant is
able to provide safe and sustainable electricity,”
says Koeberg Power Station Manager Velaphi
Ntuli. “This strategy includes reducing the
power station’s daily water usage, keeping
adequate on-site water storage and looking at
alternative water supplies, which include both
groundwater and sea water.”
As part of the rental agreement, Veolia
supplies three in its range of Hydrex
chemicals as well as the chemicals for
remineralisation, iron removal, disinfection
and pH. “The plant produces quality potable
water fit for human consumption, and to
a standard that meets the water quality
34 WAVE I JUNE 2018
standards for chemistry requirements as
specified for demineralised desalinated water
and potable water,” adds Jaco Oosthuizen,
Technical Manager, Industrial Division, Veolia
South Africa.
“A key success in the project is the smooth
handover from the Johannesburg-based
project team to the Veolia operational
team, with local headquarters based in
Paarl,” comments Oosthuizen. “It is a very
experienced operations and maintenance
team who also manage numerous industrial
treatment plants for clients, as well as the
Overstrand Municipal Water and Wastewater
Treatment Operations Management Contract
– one of the largest municipal outsourcing
contracts currently in southern Africa.”
Six trained personal from this division
operate and maintain the Eskom Koeberg
containerised plant for the duration of the
rental agreement.
This is one of the first plants to be brought
on line to assist in alleviating the strain from
industrial and power station activities on the
limited water resources in the Cape Town
water system during this protracted drought
in the Western Cape.
Koeberg, which can only operate for
approximately two weeks without offsite
potable water, is Africa’s only nuclear power
station and has an installed capacity of 1
860MW. The station has operated safely and
efficiently for 33 years, and provides 50% of
the Western Cape’s and approximately 5.6% of
South Africa’s energy needs. “The desalination
solution was, therefore, quite important to
ensure continuity of supply,” says Ntuli. “It is
worth noting that Koeberg Power Station saves
22 billion litres of fresh water per annum as its
condensers are cooled by means of seawater,
which is returned to the sea after use.”
Veolia has guaranteed the quality of the
process water and that the brine returned
to the ocean will comply with the coastal
discharge limits as required by law.
Veolia is very proud to produce this
desalination plant locally, which is a result of
a big investment undertaken two years ago
in a new manufacturing facility. During the
severe drought in the Southern Cape eight
years ago, Veolia designed and constructed
seven desalination plants, of which the
Mossel Bay Seawater Desalination plant
was the largest in the country at that time.
A number of the skids that were imported
then, can now be produced in our own
workshop facility. The new facility does
not only fabricate desalination skids, but
also containerised plants, modular plants,
mobile plants, package plants, and more. This
manufacturing facility comprises an area in
excess of 10,000 m, with a staff complement
of 26 engineers and drafting personnel, eight
welders, eight pipe fitters and plasticians,
two boilermakers and more. There is a total
of 65 staff working at the Veolia South Africa
manufacturing facility. ●

Veolia provides operational support to
TC Smelter’swater treatment
facilitiesI n December 2017 Samancor Chrome
appointed Veolia Water Solutions &
Technologies South Africa (Veolia) to manage
a number of their water treatment facilities
on site at the TC Smelter in Buffelsfontein,
Mooinooi, North West. The initial supply
contract is for a one trial basis, with a longer
3 to 5 year contract possible when the
client is satisfied with the services and KPI
achievements obtained during this trial year.
Veolia supplies operational support, with
one permanent engineer on site and a
second technician being on site for 3 days
per week. Veolia invested over a ZAR1000k in
onsite CAPEX related to dosing and control
equipment. They are responsible for operating
the disinfection of incoming water, the open
and closed cooling applications for the furnace
and the thickeners for suspended solids
removal. As part of the contract, Veolia also
supplies Hydrex flocculants, coagulants, anti-
scalants and biocides.
In 2016 Samancor Chrome acquired the assets
of the operation and transferred them into
a separate entity named TC Smelters (PTY)
Limited. The plant is situated in Mooinooi,
North West Province and is adjacent to WCM.
The core business of the operation is the
production of charge chrome using two closed
SAFs, a metal recovery plant, and a Pellet and
Sintering Plant (PSP).* ●
