What is the point of water towers? A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a water supply system for the distribution of potable water, and to provide emergency storage in case the town runs out of water. Today, many elevated towers exist for local municipalities and even for individual buildings, but the towers that we supply are engineered products usually designed by an architect and landscape designing team to enhance the look and feel of the property. They are fully functional in terms of producing water pressure, but are aesthetic for the most part, especially when signage is incorporated as a purposeful dual impact. Water towers are able to supply water even during power outages, because they rely on hydrostatic pressure produced by elevation of water and gravity pushes the water into domestic and industrial water distribution systems; however, they cannot supply the water for a long time without power, because a pump is typically required to refill the tower. A water tower also serves as a reservoir to help with water needs during peak usage times. 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. Many early water towers are now considered historically significant and have been included in various historical listings around the world. Some are converted to apartments or exclusive individual properties and homes. In certain areas, such as Chicago, Boston, and New York City in the United States, smaller water towers are constructed for individual buildings and are used presently. In many other towns, cities, and in some other states, domestic water towers enclosed by siding tankhouses were once built (1850s–1930s) to supply individual homes; windmills pumped water from hand-dug wells up into the tank, a process developed centuries before from Western Europe.
