Washington, DC --Brief Overview: A Recent UNICEF and CARE water and sanitation monitoring program in 14 governorates in Central and Southern Iraq found that out of 177 water treatment plants, 19% were classified as good, 55% acceptable, and 26% poor.

Many of the water and sewage treatment plants were in poor states of operation prior to hostilities. In the Northern governorates, in general, potable water supply and sanitation systems are operating at greater capacity than in the central and southern areas of the country.

Issues include:

• Repairs on main water network are underway, but are often constrained by lack of security.
• Many of the water and sewage treatment plants are dependent on electricity for their normal operations.
• Some back-up generators exist but many of these systems are plagued by the lack of spare parts and normal maintenance, vandalism, and lack of fuel.
• Generally there is a lack of trained and available manpower to operate the treatment plants on a regular basis, etc.
• Solid waste collection and disposal is hampered by a lack of a trucking fleet and excavators.
• Water quality and the treatment of sewage remain primary concerns for the long term rehabilitation efforts.

Successes include:

• USAID grantee UNICEF has established a water and sanitation coordinating working group that has been attended by USAID officials, other United Nations groups, NGOs, and Bechtel.
• Strengthening evaluations are being undertaken in Basrah at several of the water treatment plants to determine the present quality of the drinking water.
• With USAID funding, CARE has undertaken emergency water rehabilitation in Qaim and Ar Rutbah in the Al Anbar governorate, benefiting 80,000 persons.
• With USAID funding, Save the Children has provided two submersible pumps to facilitate maintenance of main pumps at the Wafal Qaed water treatment and pumping station in collaboration with UNICEF. Approximately 500,000 persons will benefit from these activities. Save the Children is also reviewing 78 primary health care facilities in the Al Basrah governorate and will supply some of these centers with piped water and sanitation facilities.
• Bechtel has prepared preliminary estimates of repairing water treatment plants in eastern Baghdad that would increase treated water by 45%.
• Bechtel is developing rehabilitation plans for 8 potable water treatment facilities in the Basrah region and rehabilitating 6 waste water treatment plants in south central Iraq.
• Through USAID funding, UNICEF has purchased chlorine gas, bleaching powder, chlorinators, water purification tablets, and aluminum sulphate.
• Numerous hospital and public health clinic potable water and sanitation systems have been repaired by the NGO community through USAID funding.
• Millions of liters of potable water have been provided by water trucks to the Iraqi population over the past two months.
• City water authorities (for example, the Baghdad Water Authority and the Al Basrah Water Authority) have been engaged by USAID's partners to assess current water and sewage systems and provide information and input to plans for rehabilitating municipal systems.

Credit for providing emergency and relief potable water to the population is due to UNICEF and other United Nations Organizations, International NGOs, USAID, Kuwaiti government, and local water authority staff.

WATERBURY, CT, USA-July 30, 2003-Haestad Methods today announced the commercial availability of "Hammer", a revolutionary hydraulic transient modeling solution for meeting the challenges of water hammer and pressure surge projects. Based on technology acquired from the Environmental Hydraulics Group Inc. (EHG), Canada, Hammer is the easiest-to-use transient software on the market, and it will allow the vast majority of consultants and engineers to perform hydraulic transient modeling.

"This acquisition and the ongoing collaboration with EHG further demonstrates our ability to rapidly deliver critical technology to the water resources community," said John Haestad, President and CEO of Haestad Methods. "Hammer's robust analysis engine and sophisticated visualization tools provide water utilities with the only user-friendly technology on the market for understanding, detecting, and securing their systems from the threat of transients. "

Hydraulic transients are the flow and pressure conditions that occur between two very different steady states. Counterintuitive phenomenon can occur during transient events, such as water flowing uphill or flashing into vapor. The effects of such events on a water distribution system can lead to unreliable water quality and costly repair bills.

For example, a low-pressure transient event, arising from a power failure or pipe break, can cause the intrusion of contaminated groundwater. In addition, high-pressure surges caused by the rapid closure of a valve can result in pressure waves whose magnitude is several times greater than those calculated by steady state analyses. By alerting water utilities of extreme transient pressures, Hammer supports engineers in their efforts to reduce the risk of system failure, minimize leakage, improve operating strategies and enhance water quality, all of which help ensure public safety and the longevity of the infrastructure.

Anthony Parente commented on how the Region of Peel, Canada, benefited from Hammer, "We needed to protect all pump stations and main feedermains from water hammer damage as well as the thousands of water distribution pipes in connected pressure zones. The results of the Hammer analysis led to a solid surge control strategy to protect the water system."

Haestad Methods has been in the business of enabling engineers with technology for 25 years and is internationally recognized as the world's leading water resources software company. The company provides more than 130,000 civil engineers in over 170 countries with hydrologic and hydraulic modeling software, services, continuing education workshops, and publications.

LENEXA, KS – For food processing facilities that are searching for an onsite solution to treat the problems of handling and treating their wastewater, Smith & Loveless has the answer: Modular FAST (Fixed Activated Sludge Treatment System).

The Modular FAST aerobic treatment system uses the proven FAST process to lower BOD and TSS levels in high strength wastewater streams. This technology, applied in numerous industries, has been specially designed to meet the specific demands of food industry wastewater. It provides safe, onsite pretreatment for flows up to 150,000 GPD, allowing discharge to a leach field, lagoon, constructed wetland or city sewer.

Food processors often have problems with high strength waste (high BOD levels) generated from wasted batches and the on going required rinsing and sanitation of processing equipment. Facilities that utilize conventional aeration pond or mound systems experience irritating odors and reduced treatment capacity when systems are overloaded. Additionally, those that send wastewater to the municipal sewer system can receive costly surcharges or increased scrutiny from regulators for excessive waste levels.

Modular FAST offers a solution to these issues because of its effectiveness and simplicity. By combining three biological processes in one tank – aeration, clarification, and digestion - the fixed-film reactor with submerged media capably treats high BOD levels and eliminates the need for a separate clarifier.

Additionally, it maintains high loading rate capacity and easily handles variations in flow and loading. As a result, BOD levels are significantly reduced below necessary organic loading and solids limits. The system installs above or below ground in tanks suitable for the application – such as concrete or steel, and uses significantly less total area. Equally important, it requires no daily operator attention.

LONG BEACH, CA -- Earth Tech has been awarded a $13 million construction management contract for two separate water projects in Lee County, Florida. Preliminary design on these two projects has already begun with construction slated for late 2003.

The two projects include the expansion of the existing Corkscrew Water Treatment Plant from 10 MGD to 15 MGD and the construction of the Green Meadow Storage Facility, pump station, and interconnection between the Corkscrew and Green Meadow WTP.

Construction at Green Meadow will include two five (5) million gallon ground storage tanks, high service pumping station, electrical and instrumentation control building, piping to interconnect with existing transmission mains, and various site improvements such as clearing, grading, fill, paving and fencing.

“These projects are very important to the communities within Lee County,” said Bob Mead, president of Earth Tech. “Lee County is an area that is experiencing rapid growth and the county’s water supply is in need of capacity expansion. Lee County's potable water supply capacity is currently about 27 million gallons per day. Projections call for 45 million gallons per day by the year 2020. The new interconnects between the water plants and storage tanks will give the county added flexibility in operating the system.”

The Corkscrew WTP expansion and improvement project includes construction of a new 55 foot diameter lime softening contact tank, lime silo, aeration basin, re-carbonation basin, four Leopold filter basins, high volume air blowers and piping, electrical control panels, standby generator switchgear, instrumentation and control systems, minor interior remodeling and associated yard piping and appurtenances.

During the design phase of each project, Earth Tech will act as a member of design team to provide construction recommendations, constructability reviews, alternate material selections, construction schedules, start-up planning, coordination meetings and development of bid packages. Throughout the construction period, Earth Tech will manage the process including, cost control, material deliveries, component installation and records management system.
