Water distribution systems rely on interconnected elements, such as pipes, pumps, and service reservoirs, to transport treated water from one or more sources to customers spread out across a wide area. Considering the substantial capital costs and ongoing expenses associated with maintenance and repairs, it is crucial to prioritize the development of more cost-effective and efficient designs.

Water distribution systems consist of three primary components: pumping stations, distribution storage, and distribution piping. These components can be further subdivided into subcomponents, which can then be broken down into sub-subcomponents. For instance, the pumping station component encompasses sub-components such as structural elements, electrical systems, piping, and pumping units. The pumping unit can be further divided into sub-subcomponents, including the pump, driver, controls, and power transmission.

The precise classification of components, subcomponents, and sub-subcomponents depends on the required level of analysis detail, as well as the availability of data. Ultimately, the concept of component-subcomponent-sub-subcomponent establishes a hierarchical framework of building blocks essential for constructing water distribution systems.
