Potable water tanks and any parts of the potable water distribution system shall be cleaned, disinfected and flushed with potable water: Before being placed in service; andBefore returning to operation after repair or replacement; orAfter being subjected to any contamination, including entry into a potable water tank. Potable water tanks are required to be inspected, cleaned and disinfected during dry docks and wet docks or every two years, whichever is less. On sea-going vessels and marine structures, it has been recommended that two potable water tanks be installed for good reliability of the water supply system.
Modeling of Flow Problems
Published in Krishnan Murugesan, Modeling and Simulation in Thermal and Fluids Engineering, 2023
Analysis of flow problems requires the solution of the continuity and momentum equations for the given flow domain and such type of problems are generally studied under computational fluid dynamics. In reality, not all problems related to fluid flow involve the solution of continuity and momentum equations. A simple flow problem that everyone comes across today is discussed in this section. Filling and discharge of water from a water tank is a common problem. The storage water tank size is decided based on the requirement of water for use in a day, and accordingly the size of pipe and capacity of pump are decided. However, the fluid mechanics behind such problems can be analyzed by modeling this problem using mass conservation and momentum equation in simpler terms in the following section. With the help of a mathematical model for such a problem, a simulation program can be developed using which the effect of various parameters can be analyzed.

A water tank is a container to store water. The stored water may be later distributed for drinking purpose, irrigation, or for putting out fire. A water tank can be placed either at the ground level or on an elevated stage depending on the head available for flow. It can be made of steel, concrete, or plastics. It can be of rectangular or circular in shape. Tanks are also used for rainwater harvesting. Rainwater runoff from roof tops can be collected in a rainwater tank (also known as a rain barrel) via rain gutters. The stored rainwater may later be used for agriculture, in washing machines, watering gardens, washing cars, flushing toilets, and so on. A typical example of elevated drinking water tank is shown in Figure 1.9.

Generally, there are three types of water tanks; tanks that are resting on the ground, elevated tanks and underground tanks. The lower tanks in the buildings are located underground, where their walls are subjected to pressure while their bases are subjected to the weight of water and the pressure of soil.
