Atlanta, GA -- Skanska has been awarded the contract for construction of a new combined sewer overflow plant in Atlanta, Georgia. The contract amount of $47M is included in order bookings for the third quarter. The customer is the City of Atlanta.

The assignment relates to the West Area Combined Sewer Overflow Treatment Plant, which is being constructed to improve treatment of sewage and storm water in west Atlanta.

Skanska will be carrying out large-scale civil engineering work, including basins and landscaping work, as well as constructing the buildings to house the facility's control and operations centers. The project also includes extensive installations of process equipment, piping and electrical and regulatory systems.

Work will begin in September and is scheduled to be completed in the end of 2007.  The facility will have a capacity of 322,000 cubic meters per day (85 million gallons per day) and will be linked to the West Area Tunnel, a planned reservoir designed to handle high flows of storm water.

The treatment plant will be constructed by Skanska USA Civil's unit Atlantic Skanska, which within the last year has secured three water treatment plant projects in the Greater Atlanta area, with a combined value of USD 103 M.

Atlantic Skanska is based in Atlanta, Georgia, and is engaged in civil engineering construction projects in the southeastern US.

Skanska USA Civil specializes in such infrastructure projects as construction of bridges, highways, power generation and public transit systems as well as water treatment and water pollution control plants. With operations in the eastern US, Colorado and California, the company has some 4,400 employees. Skanska USA Civil posted sales in 2004 of about SEK 12 billion.

Free : EPA's Watershed-Protection Handbook

Washington, DC -- Questions about managing pollution runoff, increasing wildlife habitat and controlling invasive species in the nation's estuaries are among those addressed in a new Environmental Protection Agency handbook released at the White House Conference on Cooperative Conservation in St. Louis.

Community-Based Watershed Management: Lessons from the National Estuary Program is an update to Saving Bays and Estuaries, published in 1989. While the new handbook focuses on estuaries, its principles and examples are relevant to any organization involved in watershed management.

The 98-page handbook describes innovative approaches developed and conducted by the 28 National Estuary Programs, which are community-based watershed-management organizations that restore and protect coastal watersheds. Topics covered range from starting a program, identifying problems and solutions to plan development and action steps.

"We anticipate that this handbook will be a useful tool for watershed protection," said EPA Assistant Administrator for Water Benjamin H. Grumbles. "It's an A-to-Z, how-to guide for everyone involved in estuary management as well as those interested in the protection of non-coastal watersheds."

Estuaries and the lands surrounding them are where rivers meet the sea, and where fresh water meets salt water. The National Estuary Program centers on four areas of the United States: Northeast, Middle and South Atlantic, Gulf of Mexico, and the West Coast.

Community-Based Watershed Management is on EPA's website and can be downloaded at: http://www.epa.gov/owow/estuaries/nepprimer For more information about the National Estuary Program, go to: http://www.epa.gov/owow/estuaries/

ALBUQUERQUE, NM -- Over the next several months a team of researchers from the National Nuclear Security Administration’s Sandia National Laboratories will be studying different methods of arsenic removal at the Desert Sands Mutual Domestic Water Consumers Association (MDWCA) in Anthony in southern New Mexico.

The research is sponsored by the Arsenic Water Technology Partnership, a consortium of Sandia; the Awwa Research Foundation (AwwaRF); and WERC, A Consortium for Environmental Education and Technology Development. U.S. Sen. Pete Domenici, R-N.M., secured the funding for the project through the U.S. Department of Energy (DOE) as chairman of the Senate Energy and Water Development Appropriations Subcommittee. At the ceremony on Friday, Aug. 26, Sandia and the MDWCA will sign a memorandum of understanding (MOU) to begin the research.

Pilot test ‘lift-off’ ceremony set

A ceremony marking the start of the Desert Sands Mutual Domestic Water Consumers Association arsenic removal project is set for Friday, Aug. 26, at 10 a.m. at the main well site. On hand will be representatives from Sandia, Sen. Pete Domenici’s office, the State Legislature, and the water utility.

“The Desert Sands project will supplement a full-scale demonstration by the U.S. EPA [Environmental Protection Agency] for evaluation of a removal technology that uses granular iron oxide to filter arsenic from water,” says Malcolm Siegel, Sandia project manager. “As water is pumped through the system, arsenic sticks to the iron oxide. The Desert Sands MDWCA wants Sandia to compare the performance of the [iron oxide] material they are currently using to other adsorptive media. We should be able to give them some practical advice based on what we learn.”

The Sandia field team includes lead engineer Malynda Aragon and field technicians Randy Everett and William Holub. Aragon anticipates they will test between eight and 12 different arsenic removal systems at the Anthony site. “We’ll be looking at which material best adsorbs arsenic to compare how often the adsorptive media needs to be changed,” she says.

The treatment system, including plastic columns filled with adsorptive material and monitoring equipment, was built at Sandia and was recently relocated to the Desert Sands utility.

Desert Sands serves a population of 1,535 from two wells in a rural community along the New Mexico-Texas state line, north of El Paso. It has a new water treatment plant built by Severn Trent Corp. that uses the iron oxide treatment method. (...more)

Mr. Poonam has a problem with TDS:

What treatment methods are available to remove dissolved solids cause even after chemical treatment using aluminum sulphate and a polymer. The dissolved solids in my water doesn't decrease. Actually treating river water for use in dyeing industry where total dissolved solids needs to be below 50 ppm.

But the TDS remains in the range of 150-200 ppm even after clarification, filtration and softening, though the turbidity decreases to around 0.5 NTU and hardness to around less than 10 ppm. (Click here to post a reply)

Mr. Carroll needs help with preventive maintenance:

Does anyone have any good preventative maintenance checklists for collection systems?  We have Gorman Rupp pumps, above and below ground.  Some transducer and some bubbler controls.  We also have backup generators at most stations.

It is a new day and we are moving in a better direction I hope for our preventative maintenance program.  (Click here to post a reply)
