Kansas City, Mo. (December 13, 2002)
-- Black & Veatch Corporation, a leading global engineering,
construction and consulting company, announced today that the
company, in conjunction with Thames Water Utilities, Ltd. of the
United Kingdom, has completed a comprehensive report on the
operations and maintenance of granular media filters.
he
American Water Works Association Research Foundation (AwwaRF) and
the U.S. Environmental Protection Agency (EPA) sponsored and
published the Filter Maintenance and Operations Guidance Manual to
provide water utility employees and other water treatment
professionals with practical tools to determine current conditions
and performance, identify deficiencies and solve pretreatment and
filtration problems, and optimize the operation and maintenance of
rapid gravity and pressure filtration plants.
"The comprehensive, four-year
study draws on the insights and the differing water characteristics
of numerous treatment facilities in the United States, Canada, and
the United Kingdom," said Principal Investigator Dr. Gary
Logsdon, senior water research engineer and a member of PROTEUS,
Black & Veatch's global team of water and wastewater treatment
process and technology experts. "The research and resulting
manual establishes international best practices for maximizing
assets and enhancing water filtration practices."
The manual emphasizes the development
of detailed preventive maintenance programs, backwash methods and
techniques to help utility and plant managers, operators and
consultants accurately assess and improve filter performance. The
project team of filtration experts from Black & Veatch and
Thames Water incorporated the collective wisdom and experience of 36
water utilities in North America, a utility in the United Kingdom
and another in Australia, peer-reviewed literature, AWWA conference
proceedings, a Project Advisory Committee, and a Technical Review
Group.
According to AwwaRF Project Manager
Traci Case, a guidance manual was needed to help water utilities
cope with increasingly stringent regulatory standards for water
filtration plants employing granular media filters. It is expected
to result in more effective problem-solving and improved filtered
water quality. Technology Transfer Workshops have helped launch the
manual, which is now available to AwwaRF sponsors and will be sold
to other individuals and organizations in 2003 by the American Water
Works Association. For more information about the American Water
Works Association Research Foundation, visit www.AwwaRF.com.
"Black & Veatch is proud to
play a prominent part in this important AwwaRF project," said
Dan McCarthy, president of the Americas Division within the
company's Water Sector. "We continue to build a world of
difference through innovation, technology application, and
participation in this and other significant water industry research
efforts."

Earth
Tech Awarded Arlington County Wastewater Project
LONG BEACH, Calif., December 5, 2002
- Earth Tech, a unit of Tyco Engineered Products and Services, has
been awarded a four-year contract by the Arlington County Water
Pollution Control Division in Virginia to provide program management
for the County's Water Pollution Control Plant (WPCP) upgrade and
expansion. The four-year contract is valued at more than $11
million; work under the contract has already begun. The project's
construction has been estimated at more than $100 million.
Earth Tech will oversee all aspects
of design and construction for major system improvements, as well as
provide community outreach support services, including:
Providing program management,
including program planning and scheduling; financial reporting;
project packaging analysis (design and construction); and
regulatory agency coordination.
Design management, including
Arlington County's Master Plan 2001 evaluation; design standards
preparation; and design reviews.
Construction management, including
administering project controls; providing resident engineer and
inspection services; start-up and turnover coordination; and
contract closeout.
Arlington County is implementing its
Master Plan 2001, which outlines how the plant will expand from its
existing 30 million gallons per day (MGD) plant to a 40 MGD plant
while upgrading the facility to reliably implement biological
nutrient removal (BNR) at flows above 30 MGD, meet more stringent
effluent limits, and minimize wet weather bypasses.
"Arlington County's capital
improvements project is ideally suited to Earth Tech's experience
and expertise," said Diane C. Creel, president of Earth Tech.
"The project also represents a significant opportunity to
establish a new client and further expands our presence in the
Washington, D.C. metropolitan area. We're very pleased to be
partnering with Arlington County for this critical infrastructure
expansion and upgrade."

Super Shredder Shears Tough Sewage to
Bits
Livingston, NJ --The Super Shredder
in-line disintegrator easily reduces tough solids directly in
industrial sludge and waste handling processes. The unit combines
unsurpassed grinding capabilities with streamlined, easy to maintain
features.
Its innovative design provides a high
level of open area to fluid flow making the Super Shredder ideal for
applications requiring a heavy duty size reduction processor that
can handle high flows with minimal headloss. The Super Shredder
features a patented "spherical shredding" mechanism that
cuts and shears tough sewage solids into fine bits. The hard faced
stainless steel cutters offer unsurpassed wear resistance.
Because of the spherical rotor
design, the Super Shredder has far less moving parts and therefore
requires far less maintenance than units with banks of cutter disks.
With two easily replaceable one piece cutters, maintenance is
convenient and down time is minimal.
Included with the Super Shredder is a
S-250 Auto-Reversing control system that senses jam conditions and
automatically reverses.

Ms. Langelier needs help
irrigation well water:
The sodium level in the water is 284
PPM and needs to be reduced so it can be used for irrigation
purposes only. Are there any systems (injection?) that can
lower the sodium level so that the well will not have to be abandon?
The well is hooked up to (2) 5,000 gallon holding tanks.
Help!!!

We are designing a pump station to
serve a seasonal high flow customer, an amusement park. The
pumping conditions are 370 GPM @ 240' TDH. We are currently
investigating a two stage station (2 pumps in series). Is
there a better solution than what we are attempting?
