The plant construction cost was over $3 billion,[6][3] The facility was built 160 feet (49 m) under Van Cortlandt Park's Mosholu Golf Course in the Bronx.

The water in the Croton Aqueduct system, the oldest of the three, often had high turbidity levels, which limits the effectiveness of chlorination as a disinfection process.

[2] The Croton plant has a capacity of 320 million U.S. gallons (1.2 billion liters) per day and is designed to remove 99.9% of Giardia cysts, Cryptosporidium, and viruses.

The system uses conventional drinking water treatment technologies: The filtration plant was originally projected to cost $800 million,[3] but the project experienced delays and ballooning costs due to objections from the local community,[7] which required the city to propose alternate sites for such a plant.

[15][16] The Sachkerah Woods Playground, located at the park's southeast corner near the Mosholu Golf Course, was also built using Croton mitigation funds.
