A water tank is a container for Water storage, for many applications, drinking water, irrigation, fire suppression, farming, both for plants and livestock, chemical manufacturing, food preparation as well as many other uses. Water tank parameters include the general design of the tank, and choice of construction materials, linings. Various materials are used for making a water tank: plastics (polyethylene, polypropylene), fiberglass, concrete, stone, steel (welded or bolted, carbon, or stainless). Earthen pots, such as matki used in South Asia, can also be used for water storage. Water tanks are an efficient way to help developing countries to store clean water.
Ground water tank, made of lined carbon steel, 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.
An elevated water tank, also known as a water tower, will create a pressure at the ground-level outlet of 1 kPa per or 1 psi per of elevation. Thus a tank elevated to 20 metres creates about 200 kPa and a tank elevated to 70 feet creates about 30 psi of discharge pressure, sufficient for most domestic and industrial requirements.
Vertical cylindrical dome top tanks may hold from 200 litres or fifty gallons to several million gallons. Horizontal cylindrical tanks are typically used for transport because their low-profile creates a low center of gravity helping to maintain equilibrium for the transport vehicle, trailer or truck.
A Hydro-pneumatic tank is typically a horizontal pressurized storage tank. Pressurizing this reservoir of water creates a surge free delivery of stored water into the distribution system.
Fiberglass tanks/vessels are used to store liquids underground.
A safety based news article linked copper poisoning as originating from a plastic tank. The article indicated that rainwater was collected and stored in a plastic tank and that the tank did nothing to mitigate the low pH. The water was then brought into homes with copper piping, the copper was released by the high acid rainwater and caused poisoning in humans. Since the plastic tank is an inert container, it has no effect on the incoming water. Good practice would be to analyze any water source periodically and treat accordingly, in this case, the collected acid rain should be analyzed, and pH adjusted before being brought into a domestic water supply system.
The release of copper due to acidic water may be monitored by a variety of technology, beginning with pH strips and going to more sophisticated pH monitors, indicate pH which when acidic or caustic, some with output communication capabilities. Most of the algae growth occurs at an optimum pH, between 8.2 - 8.7. pH level that is neutral or lower can help to reduce the growth of algae. Potential algaecide, Hypochlorite will help to clean swimming pools or water tanks from algae. In this process no need to use vacuum cleaner to remove algae. There is no causative link between the plastic tank and copper poisoning, a solution to the problem is to monitor stored rainwater with pH indicators and add appropriate treatment materials.
ROVs offer a non-intrusive means to inspect water tanks, allowing for detailed examination without direct human entry, thereby increasing operational safety and efficiency. Thermal imaging, on the other hand, is particularly effective in low-visibility and harsh environments, as it facilitates the identification of temperature anomalies that may indicate leaks, weaknesses, or other faults within the tank structure. This application of thermal imaging in structural health monitoring has been substantiated in recent studies,. Together, these technologies enable comprehensive diagnostics that surpass traditional inspection methods, ensuring water tanks meet the highest standards of reliability and regulatory compliance.
