Water Tank

Water tanks are liquid storage containers, these tanks are usually storing water for human consumption. The need for water tank systems is as old as civilized man. A water tank provides for the storage of drinking water potable, irrigation agriculture, fire suppression, agricultural farming and livestock, chemical manufacturing, food preparation as well as many other possible solutions. Various materials are used for making a water tank: plastics (polyethylene, polypropylene), fiberglass, concrete, stone, steel (welded or bolted, carbon or stainless). Earthen ponds function as water storage and are often referred to as tanks.

Ground water tank is made of lined carbon steel, it may receive water from a water well or from surface water allowing a large volume of water to be placed in inventory and used during peak demand cycles. Elevated Water Tanks also known as water towers, by elevating the water tank the increased elevation creates a, system distribution, pressure at the tank outlet of 1 psi per 2.31 feet of elevation, thus a tank elevated to 70 feet creates about 30 psi of discharge pressure, 30 psi is sufficient for most domestic and industrial requirements. (background legs shown) Chemical contact tanks of FDA and NSF polyethylene construction, allows retention time for water and chemicals to be in contact and mix.

Vertical cylindrical dome top tanks may hold from fifty gallons to several million gallons. Horizontal cylindrical tanks are typically used for transport; this low-profile transport storage creates a low center of gravity helping to maintain equilibrium for the transport vehicle, trailer or truck. Hydro-pneumatic tanks are typically horizontal pressurized storage tanks. Pressurizing this reservoir of water creates a surge free delivery of stored water into the distribution system.

Space flight simulator use elaborate water tanks for the simulation of weightlessness. Water tanks fabricated to resemble space craft interiors are suspended in large swimming pool like environments, giving astronauts the feeling approximating zero gravity. The Airline industry uses elaborate water tanks to simulate emergency water landings and the performance of aircraft upon entry to the water. Architecture Dampening of highrise building movement by using a highly placed volume water tank, the volume of water creates an inertia movement opposite to the building movement, slowing the building's movement, sway.
