The Simple Genius of NYC’s Water Supply System

Summary by Krater

This video explores how New York City's sprawling population is supplied with water entirely through a massive, physics-driven aqueduct and reservoir system stretching deep into the Catskill Mountains.

Answers: How does New York City get its water?

• New York City water supply
• Catskill Aqueduct
• Delaware Aqueduct
• Reservoirs and infrastructure
• Civil engineering

What it concludes

• New York City's surrounding waterways are completely unusable for quenching the city's thirst due to saltwater and pollution.
• The Catskill system is the largest unfiltered water supply in the US.
• The Delaware Aqueduct is the world's longest tunnel, holding that title for nearly a century.
• The entire New York City water delivery system is entirely physics-driven, requiring no outside forces once water enters the aqueducts.
• Tunnel No. 3 is the city's single largest capital project, costing around $6 billion and scheduled for completion in 2026.
