[1] Waters of the New Croton Aqueduct flow to the Jerome Park Reservoir in the Bronx before entering Croton Water Filtration Plant in Van Cortlandt Park for treatment, then out to distribution.
The newer aqueduct is a brick-lined tunnel, 13 feet (4.0 m) in diameter and 33 miles (53 km) long, running from the New Croton Reservoir in Westchester County to the Jerome Park Reservoir in the Bronx.
In 1997 the U.S. Environmental Protection Agency (EPA), the U.S. Department of Justice and the State of New York filed suit against the city for violating the Safe Drinking Water Act and the New York State Sanitary Code.
[5] The city government agreed to rehabilitate the New Croton Aqueduct and build a filtration plant.
The filtration system protects the public from disease-causing microorganisms such as Giardia and Cryptosporidium.
