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.

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.

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.

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

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. ●

A wastewater treatment plantfor the Monastir Technopole and textile polishing park in Tunisia

Veolia Water Technologies (VWT) has

been awarded by the Tunisian national

sanitation office (ONAS) the contract for the

design and construction of the wastewater

treatment plant for the Monastir Technopole

and textile polishing park, along with the

collection of raw sewage and discharge of

treated water. During the initial phase, the

plant, located 170 km from Tunis, will have a

treatment capacity of 6,000 m/day (100,000

PE).

VWT will deliver the project in partnership

with the Austrian company GIS Aqua Austria

GmbH (consortium leader), and the Tunisian

company Bouzguenda Frères Bâtiments et

Travaux Publics. The works will be achieved

within a 32-month program.

As part of this project, ONAS, in partnership

with the Monastir Governorship and

Monastir El Fejja Competitiveness Cluster,

signed an agreement for the study, design

and construction of the industrial wastewater

treatment plant for the Monastir Technopole

Park.

“The wastewater treatment plant will enable

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. ●

Veolia Water Oil and Gas Angola

Lda has been contracted by

Total and Sonangol to supply Veolia’s

range of Hydrex® chemicals for its

Floating Production Storage and

Offloading (FPSO) fleet operating

off the coast of Angola. Veolia

Water Technologies South Africa

will manufacture and deliver 160

tons of chemicals every six weeks

for the next three years to keep

the company’s Sulphate Removal

seawater treatment units running at

optimum capacity.

This chemical supply will augment

the V-Care Service support contract

Veolia Water Oil & Gas Angola Lda

already has with Total E&P Angola.

“V-Care Solutions is our commitment

to the oil and gas industry,” says

Hein van Niekerk, General Manager,

Hydrex & Consumables, Veolia Water

Technologies South Africa. “Through

this programme, we are able to offer

onshore and offshore services as well

as engineering, maintenance and

training contracts.”

Veolia will supply five primary

chemicals to maintain membrane

functionality of the seawater

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

production

we are

able to

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.”

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).* ●
