There are approximately 15,000 water towers dotting New York City’s rooftops. They are just as important today as they were 100 years ago. Not only do they provide daily water needs for those living in the buildings they serve, but the water they hold is also used to help extinguish fires when necessary.
What is the purpose of water towers in NYC?
As New Yorkers reached for the skies in the 1800’s, water towers became an intricate part of the buildings’ framework. As buildings grew taller than 6 stories, the main water infrastructure couldn’t handle the water pressure. Water towers were needed to move water safely to the 7th floor and above.
Why are water towers still used?
The primary function of water towers is to pressurize water for distribution. Elevating the water high above the pipes that distribute it throughout the surrounding building or community ensures that hydrostatic pressure, driven by gravity, forces the water down and through the system.
Why are there water tanks on buildings in NYC?
Tanks were placed on rooftops because the local water pressure was too weak to raise water to upper levels. When construction started to grow taller, the city required that buildings with six or more stories be equipped with a rooftop tank with a pump. About 5,000 to 10,000 gallons of water can be stored in the tanks.
Does every building in NYC have a water tower?
– Most structures taller than six stories need some sort of water tower and pump system of their own. – Water is fed to buildings through pipes in the basement. – Electric pumps push the water from the basement to roof. – It takes 2-3 hours to fill the average 10,000-gallon tank.
Do water towers keep water in them?
Water towers hold 50 times the amount of water a backyard swimming pool will hold, that is a lot of water! The towers are built to hold at least one days’ worth of water. The largest man-made water tower can hold 1.2 million gallons of water!
Why are there no water towers in California?
There are lots of water towers remaining in California, but many are being replaced with ground level storage tanks for two primary reasons: 1) there is less chance of damage in an earthquake, and 2) they can hold more water. Either way, water storage is a vital necessity in California.
Do water towers rust?
Over time, naturally occurring sediment in the water accumulates. Other times, agingtowers rust and flake.
Why do water towers not freeze?
The water level in the tower typically falls during the peak usage hours of the day, and then a pump fills it back up during the night. This process also keeps the water from freezing in cold weather, since the tower is constantly being drained and refilled.
Do water towers get dirty?
Untreated towers can collect layers of sludge and bacteria, and damaged covers can leave the water supply exposed to the open air and everything that comes with it: smog, debris and even birds or mice. When the Times tested 12 random buildings in three boroughs, they discovered coliform bacteria in eight and E.
How long can water be stored in a water tower?
Size – Typically, storage tanks are sized to hold approximately one day’s worth of water for the community served by the tower. If the pumps fail (for example, during a power failure), a standpipe or water tower should hold enough water to meet the community’s demand for about one day.
How long do water towers last?
Depending on the quality of the materials used to construct these tanks, they should last upward of ten years, and in the best case scenarios will last up to 30 years before the plastic becomes unstable.
Why does NYC still have steam pipes?
Steam provides heat and cooling to many buildings in New York. The steam system also provides humidity to art museums, steam cleaning for restaurants to clean dishes, and other uses.
Is Manhattan built over water?
Manhattan is built on land occupying the space between the Hudson and the East Rivers, a small part of the more broadly titled New Jersey-New York Estuary. Geographically, land such as this is traditionally composed of wetlands, which are marsh-like areas prone to flooding and soil erosion.
Is NYC water untreated?
New York City’s drinking water is unfiltered, making it the largest unfiltered water system in the country. NYC’s water supply primarily comes from the Croton, Catskills, and Delaware Watershed.
Are the tunnels in NYC underwater?
At the time of its opening, it was the longest continuous underwater vehicular tunnel in the world. The tunnel was originally known as the Hudson River Vehicular Tunnel or the Canal Street Tunnel.
Holland Tunnel.

Why do the tunnels in NYC have doors?
The doors were installed as part of the repairs needed after the tunnels were flooded during Superstorm Sandy supposedly to prevent future flooding.
How often are water towers filled?
Water towers typically fill up when demand for water is low. This usually happens at night after most people go to bed. The pumps at the water treatment plant continue to send out water, but instead of going to people’s sinks, the water goes into water towers for storage.
Do water towers smell?
The majority of people who live in buildings with new water towers launch complaints about the taste and smell of the water, especially in the two weeks following the replacement.
How long does it take to refill a water tower?
The system in use, on the other hand, takes two or three hours to refill the tank, using reliable, quiet and cheap small pumps. After that, gravity is all that’s needed.
Do water towers ever freeze?
It’s rare for a water tower to freeze over, even during the coldest winter months. There are methods to prevent such a hardship, as well as other ways to guard against any hazardous winter weather.
