The New Croton Aqueduct, built roughly parallel to the Old Croton Aqueduct was constructed to provide a large steady water supply for New York City. The aqueduct opened on July 15, 1890. It runs from the New Croton reservoir in Westchester County to the Jerome Park Reservoir in the Bronx, from which it distributes water to certain areas of the Bronx and Manhattan before emptying into Tunnel 1 of the Catskill/Delaware System.
In the late 1990s, New York City stopped using water from the Croton due to numerous water quality issues. In 2004, a project was started to rehabilitate the New Croton Aqueduct and build a filtration plant which is expected to come on line after 2015. The Croton Water Filtration Plant was built in Van Cortlandt Park to improve water quality. Because of these quality problems, the Croton system is bypassed or mixed with water from the Catskill Aqueduct and/or Delaware Aqueduct during times of drought. The project is over budget and behind schedule.
