DHV designs movable
barrier in Korea
K-water, part of the South Korean
directorate for public works and
water management, decided to
extend the 20-year-old Nakdong
Barrier in order to increase the
drainage capacity of the Nakdong
River, made necessary by climate
change effects and increased
sedimentation in the river's feeder
channels.
The Netherlands' engineering
consultancy DHV was involved
in the construction of the original
barrier, and worked with Samsung
Engineering & Construction and the
Korean engineering consultancy
Yooshin to complete the winning
design of the current project. The
new barrier will extend more than
300 meters long with a mid-span
of almost 100 meters.
The barrier's purpose is to direct
excess water to improve water
management, benefiting ecology,
irrigation, and floodwater safety.
The barrier is to be built on the
edge of the port city of Busan,
which is the second largest city in
Korea with 4.6 million inhabitants
and the country's most important
port.
According to DHV Project
Director Wim Klomp, "the barrier
can be compared to the Haringvliet
barrier in the Netherlands. The
big difference is that the flood
threat in Korea doesn't come
from the sea, but from the rivers
themselves. This means that the
barrier's curvature is turned toward
the sea." Construction on the
US$ 181-million project begins
in mid-2010 and is scheduled for
completion in mid-2012.
in Bothell, Washington.
The financing involved several
major international investors
including Prime Partners Asia
Merchant Capital of Singapore.
Investors in HaloSource include
the Masdar Clean Tech Fund,
Unilever Technology Ventures, Origo
Partners PLC and Mars Inc. Since
2007, the company has raised
more than $30 million to help drive
the global rollout of its drinking
water business.
HaloPure� drinking water
purification technology provides
low-cost, point-of-use water
purification without the need
for electricity or piped water.
HaloPure� kills viruses and bacteria
to produce safe drinking water.
The company sells its products
to regional, super-regional,
and multinational water device
manufacturers that seek higher
performance related to primary
disinfection, biofilm inhibition, and
safe storage.
HaloSource has established
multiple partnership arrangements
in India, China, and Brazil; all rapidly
growing economies in which the
markets for drinking water products
are growing at 20 percent per
annum. The company also recently
announced an agreement with WAL
(S.A.), the Swiss-based international
water filtration products company,
for the use of its HaloPure�
disinfection cartridges in WAL`s
jug and pitcher products, with an
initial focus on South America, the
Middle and Far East, and European
markets. In 2009 HaloPure�
became the first new drinking water
disinfection technology in more than
a decade to be granted registration
by the United States Environmental
Protection Agency.

ACCIONA consortium wins
huge Mexican contract
The Federal Government of Mexico,
through the country's National
Water Commission (Conagua),
awarded a US$ 721-million contract
for water treatment services
to a consortium that includes
the Spanish company Acciona
Agua, Promotora del Desarrollo
de Am�rica Latina, S.A. de C.V.,
Controladora de Operaciones de
Infraestructura, S.A. de C.V. (ICA);
Atlatec, S.A. de C.V.; Desarrollo y
Construcciones Urbanas, S.A. de
C.V. y Green Gas Pioneer Crossing
Energy, LLC.
The consortium will construct
the world's largest wastewater
treatment plant, serving a
population of ten million, and
operate and maintain it for 25 years.
Located in Atotonilco (Hidalgo
state), the plant will treat wastewater
that will be used to irrigate 80,000
hectares of land.
The plant will have a nominal
average treatment capacity of
35m3/second and a maximum
treatment capacity of 50m3/second,
including the evacuation of solid
waste and sludge generated. In
addition, the facility will be equipped
with a cogeneration system, which
will use biogas produced during the
digestion process.
In 2009, Acciona Agua gained
two other major contracts in Latin
America. In the Dominican Republic
province of Peravia, the company
will construct and operate a
drinking water plant and adduction
line; and for technical assistance
and maintenance for the Arrudas
wastewater treatment plant in Brazil.
The Arrudas project aims to save
US$ 22 million worth of annual
electrical energy savings and reduce
the facility's carbon emissions down
by 6,400 metric tons a year.
HaloSource investors drive
further growth
The US company HaloSource
raised US $10 million from new
investors to support the further
commercialization of its HaloPure�
water purification business, based
Kurdistan plans 12 dams
The Kurdistan Regional
Government (KRG) plans to build
12 dams in 2010, according to
the KRG Ministry of Agriculture
and Water Resources. The region
receives 18 billion cubic meters of
water every year, and consumes
seven billion m3 for drinking,
agriculture, and other uses.
Six of the dams will be built in
Erbil province, four in Slaimaniyah
province, and two in Kohuk
province. According to Director
General of Dams and Reservoirs Ali
Rashid, the design and location of
the dams have been completed,
and the budget has been allocated.
Two other dam projects are
under construction in the region:
Hamamok in Koya district, Erbil
province, and the Bawashaswar
dam in Kifri district, 100km
southeast of Kirkuk.
The engineering consultancy
Hydroprojekt Cz of Prague,
Czech Republic prepared the
detailed construction design of
the Bawashaswar dam. For many
years, this region has suffered
from high summer temperatures
in excess of 50 degrees Celsius
and water shortage. The 23-meter-
high, earth dam is expected to
accumulate 5.25 million m3 of
water for irrigation and water
supply. The length of the crest is
240 m and the width is 8 m. The
intake structure is designed for a
capacity between 2.75 to 3.8 m3/
second, depending on water levels.
ITT deal delivers offshore
water systems
Two hundred workers on an
offshore oil platform in the
Bay of Campeche will obtain
enough freshwater for drinking
and processing following a

Dragados Offshore and the US
company ITT C'treat that will deliver
turnkey potable and process
water treatment systems. The deal
also includes pumping products
from ITT Goulds Pumps, based in
Seneca Fall, New York, USA.
