Stormwater Retrofitting to Protect Drinking Water Reservoirs from the Impacts of Urban Runoff - Part 2   Water Engineering & Management July 2002   James D. Benson, AICP, and Melissa Beristain
The Kensico Reservoir Stormwater Management Program is designed to reduce fecal coliform bacteria and turbidity delivered to the reservoir by controlling and treating stormwater. The first phases of the project, assessment of the watershed, site selection and the screening and design of stormwater control and treatment facilities, were completed in July 1998. Facility construction began in the spring of 1999 and completed early in 2001. DEP has committed to monitoring and evaluating facility performance and maintaining the facilities.
