The process chart illustrates the simple construction to filter water and its function.
Overall, the construction involves two parts; the first step includes several materials for filtering water, while the second mechanism is constructed for water storage.
Initially, impure water is poured into special barrel. The barrel includes three natural resources such as sand in the first stage, charcoal in the middle, and gravel in the depth of the barrel. These materials are needed for filtering water in the first barrel.
Thereafter, the hose or special pipe functions as a connector of a filtering barrel and storage tank. The pipe absorbs pure water from the initial stage after being filtered through natural resources, and delivers it into storage tank for further keeping or drinking.
