Projects of the Twentieth Century. Ovation and WDPF control systems
replaced the 40-year old control units, resulting in huge environmental
advantages, including an end of unintentional spills into the Santa
Monica Bay, and a 95% reduction in the amount of wastewater solids
entering the Bay.
A number of other water/wastewater projects demonstrate our ability
to manage large, complex projects and deliver innovation solutions
using open-standards technology.
Borough of Ridgway
Ovation® Drastically Improves Control of Ridgway Water Treatment
Plant Processes
In the early 1990s, the Borough of Ridgway purchased
several separate systems to control their water treatment
and five-bay filtration processes. Through the years, technology
obsolescence led to difficulties in obtaining support and
spare parts for all the systems. At one point, the existing
systems completely failed, leaving Ridgway employees to
manually operate the plant for several months. Ridgway's
search for a new control system included some strict requirements
-- 1) state-of-the-art technology that would unify the
plant processes into a single system with a high degree
of reliability 2) a system that could expand and move with
them into the future 3) a financially stable vendor that
would provide long-term support and 4) a technology solution
that would meet budget constraints. The Borough selected
Emerson Process Management and its Ovation® system.
Ovation provided Ridgway with increased operating efficiencies
that directly translate into better and safer water production
for their consumers.
Results
- 25% reduction in water and
chemical usage during the backwash process
- Improved record keeping by proving
90% of information from a central source
- Improved communication with the
Laurel Mill Reservoir, eliminating four half-hour trips
to check water level each day
- Eliminated obsolescence issues with plant control equipment
- Met aggressive project schedule within five months of
project start

City of San Diego, COMNET Project
In 1994, Westinghouse (now Emerson Process Management Power & Water Solutions)
was selected by the City of San Diego's Metropolitan Wastewater Department
for the Central Operations Management Network (COMNET) project -- a massive
$1.4 billion dollar effort to upgrade its primary treatment facilities and
construct two water reclamation plants, a sludge processing
facility, and an operations center. COMNET uses process control technology
from Westinghouse Process Control to coordinate operations at more than 200
locations over 450 sq. miles, including the Point Loma Wastewater Treatment
Plant, North City Water Reclamation Plant, the Metro Biosolids Center, numerous
pump stations in the San Diego area, and later this year, South Bay, a fourth
water reclamation plant. Integrated on a 26-mile Ovation network, the City
of San Diego COMNET project is one of the world's largest integrated information
management systems for a wastewater application. |

Detroit Water and Sewerage Department (DWSD), Instrumentation,
Control, and Computer System (ICCS) Upgrade
In November 1999, the Detroit City Council unanimously awarded
to the Detroit Advanced Technologies Applications Network (DATA.NET)
a $240 million contract to upgrade the city's water/wastewater
control system infrastructure. A joint venture involving Westinghouse
Process Control (now Emerson Process Management Power & Water
Solutions) and four other firms, DATA.NET is responsible for
designing, implementing, and maintaining DWSD's department-wide
Instrumentation, Control, and Computer System (ICCS) upgrade.
Once completed, this upgrade will help solve the capacity problems
common to Detroit and other older cities with aging infrastructures
straining to serve downtown residents as well as growing suburban
populations. By providing a better, more effective way to monitor
and control DWSD's water/wastewater process, the ICCS upgrade
will lower overall maintenance and regulatory compliance costs,
and make future facility expansion easier. |

City of Los Angeles, Hyperion Wastewater Treatment Plant
The Hyperion Wastewater Treatment plant is the largest wastewater
treatment plant in Los Angeles, California. In 1984, Westinghouse
Process Control (now Emerson Process Management Power & Water Solutions)
and Sachs Electric teamed to provide a WDPF control system for solids handling
and energy recovery. In 1996, that control system was upgraded, under a
sole-source procurement agreement, to the latest technology at a fraction
of the cost of a new system. Over the years, numerous additional projects
have been initiated at Hyperion. With a fully integrated DCS and SCADA
architecture, operators perform on-line monitoring and automatically activate
remote equipment, saving time otherwise spent manually collecting, recording
and manipulating process data. |

East Bay Municipal Utility District,
Oakport Wet Weather Facility, Point Isabel, San Antonio
Creek & Dechlorination Site
To address the issue of sewer overflows during peiods of heavy
rain, the East Bay Municipal Utility District launched a multi-year,
$250 million Wet Weather Program to expand and modernize both
the collection system and treatment facilities. Emerson's integrated
DCS and SCADA architecture provide the District with an advanced
tool to manage the various problems presented in coping with
storm water instrusion. The ability to perform on-line monitoring
of rainfall intensity at critical locations, perform automatic
activation of remote equipment, and develop total flow projections
allows operators to successfully prevent overflows and avoid
process upsets. |

San Antonio Water System (SAWS), Dos Rios Recycling Center
Since 1987, the San Anotonio Water System (SAWS) has used process
control technology from Westinghouse Process Control (now Emerson
Process Management Power & Water Solutions) to create water
reutilization solutions that satisfy the water needs of local
communities while alleviating the current drain on valuable
natural resources. Dos Rios, the largest of San Antonio's four
recycling centers, is a central element in SAWS' critical water
management plan to conserve drinking water supplies. SAWS is
currently of implementing and integrating the three independent
control systems at the Leon Creek, Salado Creek and Dos Rios
Water Recycling Centers into a single PC/PLC-based control system.
Westinghouse Process Control (now Emerson Process Management
Power & Water Solutions) is creating a total-system integration
strategy to enable operators to monitor and control the three
facilities from any location. |

Sacramento Regional County Sanitation
District (SRCSD)
SRCSD Partners with Emerson to Improve
Operations and Reduce Costs with Ovation®
A five-year plan prepared by SRCSD identified the challenges
associated with a rapidly expanding service area while meeting
increased environmental regulations. Major changes to the
wastewater treatment pant computer system were required to
overcome these challenges. The facility's original process
control system, installed in 1982, had several issues. Among
other problems, it had no redundancy and no mechanism for
automatic restart when power was lost. When SRCSD set out
to replace the aging controls, plant managers knew its staff
would only accept a centralized system designed and programmed
through a true partnership with the supplier and engineering
consultant. SRCSD had two specific needs for the project
-- 1) it wanted its staff involved in programming the new
system and 2), SRCSD wanted to minimize installation time.
SRCSD enlisted EMA Services, Inc. as its contractor and selected
the Power & Water Solutions division of Emerson Process Management
as the third team member. SRCSD partnered with Emerson to
modernize the aging control system while maintaining the
previous investment in the I/O system. Emerson provided a
technically sound solution by implementing Ovation® expert
technology.
Results
- 25% under overall project
budget with the help of timely SRCSD and Emerson implementation
- $5 million estimated savings by retaining previous I/O
- $110,000 saved in testing and training costs using an
on-site trailer
- Installed seven months ahead of schedule
- Flexible system design opened the door for future installation
of an Ovation SCADA Server for improved communications
with remote pump stations

City of Akron, Water Pollution Control Division
In 1990, the City of Akron Water Pollution Control Division
initiated a program to acquire an advanced process control,
monitoring, and information system for its wastewater treatment plant.
The City recognized that to meet future environmental regulations in a
cost-effective manner, they needed to apply advanced process automation
technologies that could increase overall plant efficiency while enhancing
the flow of process information between various operational areas. The
new Westinghouse Process Control (now Emerson Process Management Power & Water
Solutions) system has contributed to significant improvements at the plant.
For example, it permitted engineers to identify process modifications that
reduce electrical consumption by as much as $250,000 per year. The control
system also allows operators to better anticipate storm water flows and
to maintain stable plant chemistry levels, resulting in a higher quality
effluent. |
