NEW ROCHELLE, N.Y. --- Westchester County Executive Rob Astorino has announced the completion of a $250 million upgrade to the New Rochelle Water Resource Recovery Facility, the largest public works project in the county’s history which was on time and under budget.
“Despite the complexity of the project to meet new environmental standards and improve water quality, our engineers’ consortium and contractor completed a state-of-the-art solution that was both on time and under budget,” Astorino said. “The upgrades to the New Rochelle WRRF, with improvements to every process in the plant, mean a 50 percent larger wastewater capacity for New Rochelle, Mamaroneck, Larchmont and Pelham, plus a substantially cleaner Long Island Sound.”
Rengachari Nivas, president of Savin Engineers, the lead designer for the engineers’ consortium, said the project saved taxpayers nearly $300 million from the original plan while delivering a wastewater treatment operation.
“We were able to exceed expectations, even of our own design and projections, with a nearly 90 percent reduction of nitrogen discharge into the Long Island Sound,” Nivas said.
Mike Ryan, president of Yonkers Contracting Co., applauded the effort and expertise of the project management team and hundreds of construction workers on the project.
“Yonkers Contracting is proud and pleased to have completed such a complex and massive project for the county of Westchester,” Ryan said. “This project is particularly rewarding because the facility provides fresh, quality water to Long Island Sound.”
In June, the engineers’ consortium that designed the upgrades, including Savin Engineers, P.C., Arcadis, CDM Smith, and GHD, was awarded Project of the Year by the New York State Society of Professional Engineers.
The New Rochelle WRRF Improvement Project consisted of upgrades to every process to meet new permitting requirements. As a result of the project, a new two-stage biological aerated filtration system has reduced nitrogen discharge to the Long Island Sound.
The project also includes ultraviolet light disinfection systems that replaced chlorine disinfection, and upgrades to the headworks and secondary treatment system to increase the plant’s capacity.
