Emerson Process Management, a business of Emerson, announced that it has received a contract to install PlantWeb digital automation architecture with the Ovation expert control system at the Croton Water Filtration Plant, which is under construction in New York City’s Bronx borough. The contract was awarded by the project’s general contractor, Skanska/Tully, a joint venture of Skanska USA Civil NE and Tully Construction.
When completed in 2012, the Croton Plant, which is the first water treatment plant located within New York City’s five boroughs, will filter up to 290 mgd from the Croton water system, which consists of 12 reservoirs and three controlled lakes located in Westchester, Putnam and Dutchess counties. Croton is one of New York City’s three reservoir systems, typically providing 10% of the city’s water, although that can increase to 30% in times of drought. Water from the Croton system is primarily used in low-lying areas of the Bronx and Manhattan. The new four-story plant, which is unique in that it is being built underground, is needed to meet the public water supply and health needs of New York City, and comply with current and future water quality regulations. It will be operated by the New York City Department of Environmental Protection.
“By filtering water from the Croton water system, this new plant will help provide safe drinking water for the residents of New York City,” said Mitch Goldstein, senior electrical project manager, I&C coordinator, Skanska USA Civil NE.
Emerson’s Ovation expert control system, which is part of Emerson’s PlantWeb digital automation solution, will monitor and control approximately 15,000 I/O points related to the new plant’s operations, including chemical feed systems, backwash systems and balance-of-plant processes. Emerson will provide four redundant Ovation controllers, 12 workstations, four operator interface terminals, AMS Suite, and Emerson smart devices, including Rosemont magnetic flowmeters, pressure and temperature transmitters, and chlorine analyzers.
Emerson will also be responsible for supplying computers, as well as network design and installation, for the administrative offices that are a part of the underground complex. The contract also includes a three-year hardware maintenance agreement.
