4. Biosep
TM
An aerobic biological
treatment for
wastewater
treatment and water
reclaim
An innovative solution developed by
Veolia Water Technologies, Biosep™
combines two proven technologies:
• Biological treatment using activated
sludge
• Membrane filtration
Biosep™ produces very high quality water,
fully compliant with the highest standards
for water reuse for irrigation, industrial and
municipal applications.
With more than 120 references worldwide,
Biosep™ is recommended for:
• Significant reduction of carbon, nitrogen
and phosphorus pollution
• High and simultaneous removal of
bacteria depending on the treated water,
completed by downstream disinfection.
Biosep™ Pack - new standard
membrane filtration units
> Flow rates from 4 to 110 m⁳/hr
> Flexible and modular solutions,
manufacturing in-house in the
Veolia workshops
> Guaranteed performances
identical to those of the
conventional Biosep™ process
Biosep™ Pack is added to a biological
aeration tank. The membrane
bioreactor replaces the traditional
settling system and separates
perfectly the purifying biomass
from the treated effluent through
microfiltration. The microfiltered
water is of excellent bacteriological
quality and removal of TSS is
guaranteed at any time. Flow rates
from 4 to 110 m⁳/hr.
Applications
> Small or medium sized industrial
effluent treatment plants (800 to
10,000 PE)
> Temporary solutions during
refurbishment or upgrade work
Biosep™ is sold under the Neosep™
trademark in Japan, the United States,
Australia and New Zealand. ●

5. Woodlands Dairy, 1000+ people, is
one of the largest manufacturers of
UHT milk in South Africa, marketed under
the brand FIRST CHOICE®. Woodlands Dairy
is a local, Eastern Cape processor of farm
fresh milk, who produces and packages high
quality dairy products. Dairy farming methods
should not only have a minimal impact on
the environment but should also be animal
friendly and boost public support for dairy
farming.
The challenge
Veolia Water Technologies South Africa (Pty)
Ltd was awarded the contract by Woodlands
Dairy (Pty) Ltd to provide a viable processing
solution for their growing process effluent
stream. The facility contains a milk sterilisation
and packaging plant as well as a cheese
factory. All process effluent is sent to a
combined effluent sump.
The Solution
Veolia Water Technologies proposed a resource
recovery plant (RRP) capable of processing 1.5
MLD, which will later be upgraded to 2 MLD.
The RRP will make use of Biothane’s state of
the art Memthane® technology, capable of
removing >95% of effluent COD.
A piloting study was performed to provide an
effluent specific treatment facility, ensuring
product performance and client satisfaction. ●

17. For decades, Bechtel has helped customers bring ambitious urban
concepts to life—from special economic zones to entire cities.
Our projects assist societies in overcoming challenges of growing
populations, connectivity, resiliency, and resource management. Rail
is core to these advancements, enabling mobility, access, industry,
and growth. Bechtel has delivered more than 300 major subway and
rail projects, and is at the forefront of building some of the largest
and most sustainable rail systems in the world today.
Transporting Riyadh’s next generation
A Bechtel-led consortium, which includes Almabani, CCC, and
Siemens, is designing and building two of six rail lines of the Riyadh
Metro Network. When complete, the 109-mile (176-kilometer) system
will ease congestion and reduce pollution by giving Riyadh’s 6.5
million residents an alternative to driving. Among the sustainable
design aspects, we are incorporating solar panels to power the
depots with renewable energy.

18. REDUCING ENVIRONMENTAL FOOTPRINTS
SCPX Circular Economy & Impact
FUEL:
Saved an average of
371,316 gallons (1.4
million liters) per year,
which equates to
removing nearly 700
cars from the road
CARBON EMISSIONS:
Prevented an average
of 3,300 metric tons of
emissions per year
WATER:
Conserved an average
of 100,000 gallons
(378,541 liters) a year,
enough to fill 1 million
12-ounce (.35-liter) water
bottles
CONSTRUCTION WASTE:
Recovered, reused,
and recycled 40 percent
annually
FOOD WASTE:
Reduced 90 percent
(990 kg/work day),
equal to about 730,000
pounds, or 365 tons, of
waste on average per
year
Greening project facilities
The Al Taweelah Alumina refinery is a greenfield project in the
United Arab Emirates that will supply 2 million tons of alumina for
smelting. With our partner, Emirates Global Aluminium, we used
Estidama (sustainability in Arabic) principles and practices at the
refinery’s operation management building to set a high bar of sus-
tainability compliance. We saved water by using water-conserving
fixtures and fittings, recycled sewage water for irrigation, and
native plants that require less water to maintain for landscaping.
To reduce energy consumption, we added external shading and
installed energy-efficient equipment and lighting systems. These
measures and others contributed to:
∙ 100 percent recycled water for irrigation
∙ 54 percent reduction in internal potable water consumption
∙ 13 percent reduction in energy use
∙ 55 percent of procured steel using recycled content
∙ 70 percent of nonhazardous construction waste recycled

19. LONG-TERM GOALS AND TARGETS
By 2030, Bechtel commits to:
It’s no longer enough to build the
biggest projects in the world. We will
also be known for building the best
projects for the world.
Bechtel delivers the most complex projects in the world for its
customers. These feats are not only modern engineering marvels;
they spur long-term prosperity and growth that transform
countries and lives.
From the Paris climate agreement to the launch of the United
Nations Sustainable Development Goals, we saw the world deci-
sively shift to a future of cleaner energy, greener infrastructure,
and universal access to clean water.
Amid this accelerating trend, Bechtel delivered for its customers,
partners, and society:
∙ Clean power for homes, cities, and businesses
∙ Rail networks that ease pollution and congestion while improving
urban mobility
∙ Communities more resilient to extreme weather and natural
disasters through our volunteer programs
∙ Less waste, energy, and water use at our projects and offices
∙ A legacy of sustainability at our projects long after our work
is complete
Bechtel also made progress on our strategy to advance sustain-
ability across our business. We’ve implemented new tools,
procedures, and initiatives to spur innovation, reduce our environ-
mental footprint, and protect vulnerable workers and communities.
These efforts form the backbone of our ambitious long-term
goals and targets.
The last century was defined and shaped by industrial develop-
ment that created generations of prosperity; this century will be
defined by sustainable development. The projects we deliver for
our customers and the world, and the way we deliver them, will
help ensure this century will flourish.
