Reston, VA -- The Mubarak Pumping Station in Toshka, Egypt, built to reclaim desert land, is one of five finalists for the 2005 Outstanding Civil Engineering Achievement Award (OCEA), presented by the American Society of Civil Engineers (ASCE). This year's award winning project will be named at ASCE's 2005 Outstanding Projects and Leaders (OPAL) awards gala on April 13 at the Sheraton Premiere at Tysons Corner, Va.

The Mubarak Pumping Station is a key element of the Egyptian government's decision in 1997 to develop a new valley where agricultural and industrial communities could grow and flourish in the country's southwestern desert. The development, known as the Toshka Project, depends on the Pumping Station, which pumps water from Lake Nasser to then be transported by way of a manmade river through the valley, transforming 588,000 acres of desert into agricultural land capable of sustaining high value fruit and vegetable crops. When the Toshka Project is completed in 2020, the valley will become home to more than three million residents and will increase Egypt's habitable land by 10 percent.

"The Mubarak Pumping Station is considered Egypt's national project for the 21st century," said ASCE President William P. Henry, P.E., F.ASCE. "Almost every aspect of the project, from dealing with extreme temperatures to the challenge of supplying materials, has expanded the boundaries of civil engineering."

With a discharge capacity of 1.2 million cubic meters per hour, the Mubarak Pumping Station is one of the largest in the world. The project's innovative design includes a pump-house completely surrounded by water, resembling an island in a lake. The station's pumps are arranged in two parallel lines down either side of the island. This design, coupled with an open channel instead of a feeder canal and the elimination of a large concrete suction basin, reduced the overall size of the pump-house and both initial and maintenance costs.

To avoid using costly concrete piles to support the structure in an earthquake and resist the effect of lateral seismic forces, a system of steel mini-piles connects to a foundation raft, which avoids their loading in compression, yet allows them to react in tension caused by seismic loads. These mini-piles around the base of the station will act to restrain any overturning forces. The pump house, subjected to temperatures ranging from 0єC to 55єC, had to be watertight, but the efficiency of water-stops used in normal expansion and contraction joints was questionable, so the pump house excludes joints below the normal high water lake level, and provides joints above it. This joint elimination necessitated a complex analysis to address thermal effects in the overall structural design.

The $436-million project is a true symbol of international cooperation in civil engineering, both in design and construction. The enormous state-of-the-art facility, designed by a joint venture between local engineering consultant Hamza Associates and Germany's Lahmeyer, was constructed by a consortium between Arabian International of Egypt, Skanska of Europe and Hitachi of Japan.

Other 2005 OCEA finalists include the Rion-Antirion Bridge over Greece's Gulf of Corinth; AirTrain JFK Light Rail System in New York; the Time Warner Center in New York City; and the Olivenhain Dam and Reservoir in San Diego.

Founded in 1852, ASCE represents more than 137,000 civil engineers worldwide, and is America's oldest national engineering society. ASCE celebrated its 150th anniversary in 2002.

NJ : Wastewater Plant to Install Solar Electric System

PENNINGTON, NJ -- WorldWater & Power Corporation, maker of high-horsepower solar energy systems, and its Joint Venture partner Conti Corp. have been awarded the contract from the Atlantic County (NJ) Utilities Authority (ACUA) to install a $3.25 million solar energy system at the wastewater treatment plant near Atlantic City. The contract will require a $1.9 million rebate from the NJ Board of Public Utilities Office of Clean Energy and a low-interest loan from the NJ Environmental Infrastructure Trust program.

Under the joint venture agreement, WorldWater & Power will supply all solar-related equipment, engineering and design services, and Conti will provide construction services and construction project management. First phase of the project is expected to be completed by August 1 and full completion by October 1, 2005.

The system will be comprised of several different arrays, on building rooftops, raised parking structures, and ground mounted. Collectively the arrays are expected to provide an annual output of 660,000 kilowatt hours in clean, economical energy.

As Richard Dovey, ACUA President, explained, "Each new project brings the ACUA closer to independence of fossil fuels. With the installation of solar panels and five wind turbines in the near future, our wastewater treatment facility will, at times, be entirely powered by clean, renewable, alternative energy. The ACUA has long been a leader in protecting our environment and is hoping to serve as an example to the community as proponents of alternative energy and stewards of our water and land."

WorldWater & Power Corp. is a full-service, international solar engineering and water management company with unique, high-powered, patented solar technology that provides solutions to a broad spectrum of the world's water supply and energy problems. The oldest solar energy company in New Jersey, WorldWater & Power specializes in the design, engineering and construction of solar electric energy systems.

Auckland, NZ -- Zebra-Tech Ltd is pleased to introduce the D-Opto range of optical dissolved oxygen sensors. The D-Opto range includes the SDI-12 D-Opto, and the D-OptoLogger. Both instruments have been specifically designed for long term environmental monitoring of dissolved oxygen in streams, rivers and lakes.

Jobs that require long term dissolved oxygen measurements with minimal drift; the D-Opto sensor is for you. D-Opto optical sensing technology is not only highly stable, but provides very accurate and reliable long-term DO measurements not possible with conventional DO sensing technologies. Additionally no oxygen is consumed during the measurement cycle removing the necessity for mechanical stirring in low or no flow. D-Opto has no consumable replacements and is un-affected by sunlight, reducing the operation costs. Designed for harsh conditions, both instruments feature a biofouling control system to minimize the build up of bio-growth.

The SDI-12 D-Opto has a very low power requirement, making it suitable for remote sites. An SDI-12 instrument is simple to integrate with dataloggers. The instrument is supplied with a small interface module to ease installation into an established logging system. This interface also enables a computer to be directly connected to the D-Opto without disconnecting the instrument from the datalogger.

D-OptoLogger is a self contained DO logging instrument. It incorporates an optical DO sensor, logger and battery in a small, rugged underwater housing. The D-OptoLogger records percent saturation, oxygen concentration and temperature at user set logging intervals. Depending on the logging interval, the instrument can be deployed for up to several months. The instrument is supplied with windows based software for configuring the logger, download data, and calibration.

Mr. Mokhtari is seeing red:

Wastewater treatment plant in my city is stabilization ponds.  This system includes one series of anaerobic pond, facultative pond and finally aerobic pond.  But in facultative pond, wastewater color is red.

I think red algae are dominant.  Treatment efficiency is moderate but we want to increase it.  Do you think red color in pond is natural?  If not, it is possible to modify pond performance?  (Click here to post a reply)

Mr. Berrisford wants help with FOG in poultry plant:

I've gone over this forum for the last couple weeks and I see some great advice. Here's my query...

I work at a wastewater plant that is fed by a poultry processing plant. There is a DAF system before the wastewater reaches us, thus we never really have any problems with FOG's. Well someone dumped a load of fat into the system and its causing a lot of suspension and Nocardia in our aeration basin, clarifier and floculative/settling lagoons. It is also rearing its ugly head in other parts of the plant.

My question is; Is there any kind of enzymes that can be added to speed up the organic processing of this fat in the aeration basin?  If so, will it help eliminate the Nocardia foam?  (Click here to post a reply)
