About Us
Where Does Our Water Come From?
Generally, tap water and bottled water sources include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water flows over land or through ground layers, it dissolves natural minerals and can pick up substances from animal presence or human activities. Potential contaminants in source water include microbes, inorganic compounds, pesticides, herbicides, organic chemicals, and radioactive materials.
To ensure public safety, both State and EPA regulations limit certain contaminant levels in public water systems. Similarly, the FDA establishes comparable limits for bottled water products.
The New Castle Water System relies entirely on the New York City Aqueduct and Reservoir Systems. Our primary source is the Catskill Aqueduct System (fed by Ashokan Reservoir), with the New Croton Aqueduct (fed by Croton Reservoir System) serving as backup. We prefer the Catskill supply due to superior water quality and lower treatment costs at our Millwood Water Treatment Plant. During 2017, we experienced no limitations on our Catskill reservoir access.
The NYS Department of Health has evaluated water supplies statewide through the Source Water Assessment Program (SWAP). These assessments use available data to estimate potential contamination risk but don't indicate actual contamination has occurred. The Town of New Castle provides comprehensive treatment and monitoring to ensure water quality meets all standards.
Our supply comes from either the Catskill watershed (west of Hudson River) or the Croton watershed (Putnam and Westchester Counties). NYC's Department of Environmental Protection implements extensive protection programs in these watersheds, focusing on: enforcing Watershed Rules and Regulations, acquiring and protecting watershed lands, and partnering with communities to address specific pollution sources.
Primary water quality concerns in these watersheds relate to agricultural activities and residential development, which can introduce microbial contaminants, pesticides, and nutrients that promote algae growth. While wastewater presents some concerns, most discharges receive advanced treatment. Other facilities like landfills and chemical storage sites pose minimal risk due to watershed size and ongoing surveillance.
The Croton reservoirs' shallow nature, combined with excess nutrients and wetlands presence, sometimes leads to increased water color and disinfection byproduct precursor levels. More information about NYC watershed protection efforts is available at www.nyc.gov/dep/watershed.

New Castle/Stanwood WD Municipal Water Company and EPANew Castle/Stanwood WD Municipal Water Report Info
New Castle constructed its Millwood Water Treatment Plant to meet the Surface Water Treatment Rule requirements implemented in 1989. Our current facility began operation in August 1993 and consistently provides high-quality water that meets or exceeds all federal standards.
The plant operates under supervision of a Grade 1-A New York State Certified Water Treatment Plant Operator and is staffed 24/7 by certified Grade 2-A Water Treatment Plant Operators. Our treatment approach minimizes chemical usage while effectively removing impurities through a five-step process:
- Initial mixing to disperse coagulation chemicals
- Flocculation with controlled mixing to trap impurities
- Dissolved Air Flotation (DAF) to remove contaminants
- Filtration through activated carbon and sand
- Disinfection with controlled chlorination
This comprehensive treatment system ensures residents receive clean, safe water that meets all health standards.
