New York City's Water system stretches across nine upstate countries. It's three watersheds -- the Croton, the Catskill, and the Delaware -- cover almost 2,000 square miles which is more than six times the size of New York City itself. Normally about 90 percent of New York City's drinking water can be traced to the Catskill and Delaware watersheds. Water systems were created from the 1860s when New York was experiencing terrible drought and fires. New York City's water supply is vital and could be its most valuable capital asset.

Most New Yorkers take New York City's dear and plentiful water supply for granted which can be in danger. The demand for water is large, it is reported that from 1960 to 1980, even as the city's population decreased, the water consumption grew by 350 million gallons per day. From my textbook source, fortunately, it showed water consumption decreasing from 1989-1990. Today, an amazing system of reservoirs, lakes, aqueducts, tunnels, and water mains distributes around 4,000,000 m3 (1.3–1.5 billion gallons) of water to nearly 9 million people every day.
