Platinum Award for the Catskill Aqueduct Optimization Program
(NEW YORK, NY – March 26, 2012) – The American Council of Engineering Companies – New York has bestowed the 2012 Platinum Award to the Catskill Aqueduct Optimization Program.
More than 74 miles long, the Catskill Aqueduct serves 14 communities in four counties in addition to providing a third of New York City’s water supply. The Optimization Program identified cost-effective improvements and implementation strategies to restore up to 70 mgd of capacity lost due to increased friction from biofilm growth on the interior surface.
Hazen and Sawyer developed an innovative approach built on historical hydraulic assessments and operating history, augmented with extensive field work and hydraulic modeling, to define current and potential aqueduct capacity. Hydraulic surveys at more than 40 locations and continuous water level monitoring at eight locations provided valuable information on aqueduct performance and friction factors. The results of these studies provided a basis for identifying a range of treatment options, including chemical addition, as an essential component of capacity improvement and maintenance.
The project enhanced NYC water system reliability without construction of costly new infrastructure. It also defined potential capacity restoration, prioritized improvement work, provided effective improvement methods, and included careful scheduling to minimize service disruptions to the communities that draw from the aqueduct.
Since our founding in 1951, Hazen and Sawyer has focused on two things: providing safe drinking water and controlling water pollution. Our range of services encompasses the planning, design, and construction management of water and wastewater-related projects – from clean water treatment, storage, and distribution to wastewater and stormwater collection, treatment, and reuse.
