Company Wins Contract To Operate Wastewater Plant
Severn Trent Services has been awarded a contract with the Lewes, DE, Board of Public Works (BPW) to operate the city's wastewater treatment plant.
The Lewes plant processes an average flow of 400,000 gallons of wastewater daily and serves a community with a population of approximately 3,000. The three-year contract for turnkey operation of the plant and 22 sewage lift stations is valued at approximately $1 million.
The Severn Trent team of scientists and engineers will work with the BPW to keep down escalating treatment costs and evaluate alternatives to the costly effluent relocation from the Lewes-Rehoboth Canal. Upcoming TMDL legislation may require the BPW to incur capital costs to relocate plant effluent from the canal.
Canadian Groundwater Network Awards Monitoring Supply Contract
Golder Associates and Solinst Canada Ltd will supply water well monitoring and telemetry equipment along with training and technical support to the Ontario Provincial Groundwater Monitoring Network (PGMN) under a 3-year contract.
Solinst will provide the equipment and Golder Associates will serve as managers of the project, installing the equipment and supplying the Central Data Management System.
The contract calls for the supply of up to 380 remote telemetry units, utilizing Leveloggers and Barologgers to measure water level, temperature and barometric pressure. These units are being installed for 38 Conservation Authorities across the Province of Ontario, Canada.
As of December 31, 2001, 73 Solinst telemetry units, 103 Leveloggers and 14 Barologgers have been installed and are currently operating. The Central Data Management System has been operating in pilot mode for 9 months.
Consultant Chosen for San Diego Pipeline Project
The San Diego County Water Authority has chosen the management consulting and engineering firm R.W. Beck as the prime consultant to provide construction management services for a water pipeline project.
The project, Moreno Lakeside Pipeline, encompasses approximately five miles of 54- to 60-inch diameter pipelines - including two tunnel segments - operated by the San Diego County Water Authority on the east side of the Southern California city.
The project is scheduled to begin in June 2002 and should be complete by September 2004.
"The pipeline project will provide water to the Levy Water Treatment Plant operated by the Helix Water District (a member agency of the San Diego County Water Authority), which serves customers in an area to the east of the City of San Diego," according to project manager Chris Dull of R.W. Beck's San Diego office.
Lake Okeechobee Project Awarded to HDR
The South Florida Water Management District (SFWMD) has awarded a contract to HDR to develop a watershed assessment and Project Implementation Report for restoration of the Lake Okeechobee Watershed in south Florida. The five-year, $6 million project represents the first major component being implemented for the Comprehensive Everglades Restoration Plan. SFWMD is co-managing the project with the U.S. Army Corps of Engineers.
"Lake Okeechobee and its watershed are key components of the Everglades ecosystem, and this restoration project plays a critical role in the projects to follow," said Henry Dean, SFWMD executive director.
The Lake Okeechobee Watershed project contains four major restoration components:
* North of Lake Okeechobee Storage Reservoir
* Taylor Creek/Nubbin Slough Storage and Treatment Area
* Lake Okeechobee Watershed Water Treatment Quality Facilities
* Lake Okeechobee Tributary Sediment Dredging
"HDR's goal is to achieve water quality, quantity and flood protection while restoring some of the most sensitive wetlands areas in the Everglades," said Elwin Larson, HDR national director, Environmental and Resource Management. "It's a delicate balance because there are so many demands on the lake, and we're honored to be selected for this complex and challenging project."
Sanitaire Acquires Royce Instruments, Controls
Sanitaire, a division of ITT Industries and supplier of aeration products and systems for municipal and industrial wastewater treatment, has expanded its product line with the addition of Royce brand instruments and controls.
"Royce's specialized wastewater treatment products enhance Sanitaire's ability to provide end-to-end solutions for municipal and industrial wastewater facilities," said Tom Pokorsky, President of Sanitaire.
The Royce product line includes DO analyzers and controllers, sludge blanket level detectors and controllers, total suspended solids analyzers and controllers, and pH/ORP instruments and electrodes.
These products complement Sanitaire's comprehensive line of aeration systems, activated sludge plants, clarifiers, airlifts, SBR's, and state-of-the-art controls. Sanitaire also offers engineering support, project management and financial services.
Sanitaire acquired the Royce products last month when it purchased certain assets of Royce Instrument Corporation, including Royce's wastewater product lines, its patents and trademarks. Royce will continue to operate from its New Orleans, LA, location and will be known as Sanitaire, Royce Technologies Unit.
Water Utility Installs New Biosolids Process
Ashbrook Corporation has been chosen to provide a Eco-Therm™ Pasteurization Process System at Eastern Municipal Water District's Temecula, CA, WWTP. Riverside County's 8.0 mgd Advanced WWTP presently sells the plant's effluent to the surrounding agricultural community, and the plant has arranged to market all of the Class A biosolids that are produced.
Estimated cost savings of up to $200,000 per year for biosolids handling alone, are expected as a result of the improved quality of biosolids.
US EPA Region 9 has reviewed and approved the use of the continuous liquid biosolids processing system which produces Class A biosolids without chemicals and may improve the dewatering properties of the material. Eastern Municipal's Strategic Plan for the coming years states in part an objective to, "Maximize recycled water and biosolids use in an environmentally responsible manner."
Companies Win Chicago Tunnel Project Contract
The Metropolitan Water Reclamation district of Chicago has awarded Affholder Inc. of Chesterfield, MO, and JayDee Contractors of Livonia, MI, a major contract for the City of Chicago's Tunnel and Reservoir Project (TARP).
The two companies will partner on the $168.7 million project that will take place in South Holland, IL, a suburb of Chicago. They will install a new pipeline that hooks into a 30-foot sewer on Indiana Avenue.
Affolder's portion of the project, which will total $72.85 million, will involve installation of eight miles of tunnel, 200 feet underground, with a nominal finished diameter of 16 feet. JayDee will be doing the service work, excavating nine drop shafts and installing 25,000 feet of pipeline. Work began on the project in March 2002, and is scheduled for completion in 48 months.
Wet Weather Facility Features UV Disinfection
The consulting firm of CDM designed, managed construction and implemented startup of the nation's first combined sewer overflow (CSO) facility combining high-rate clarification (HRC) - a CDM-pioneered technology - with ultraviolet disinfection.
The system will treat overflows in Bremerton, WA. The facility began operation in December 2001, reducing pollutants to Puget Sound. The city of Bremerton, divided by the Port Washington Narrows and Dyes Inlet, sought cost-effective treatment of CSOs as part of a $30 million plan to reduce untreated discharges to local waters.
An HRC/UV facility is an alternative to conventional treatment, saving Bremerton more than $5 million over the next least-cost alternative of constructing storage and relief sewers. It offered the advantages of a small site footprint, a short 15-minute startup, 50 gpm/square foot treatment rate, and efficient pollutant removal. Facility construction cost approximately $4.1 million, or 20 cents per gallon of capacity.
HRC achieves a suspended solids removal rate of more than 10 times the normal clarifier loading rate, removing 85-90 percent total phosphorus, making Bremerton the first community in the Puget Sound area to surpass CSO standards.
