What is one of the primary functions of storage tanks in water distribution systems?

One of the primary functions of storage tanks in water distribution systems is to provide a reserve of water during peak demand. This is crucial because water use can fluctuate significantly throughout the day and between different seasons. Storage tanks act as buffers that store excess water when demand is low and release it during times of high demand, ensuring a consistent supply of water for users.

During peak demand periods, such as morning hours when people are getting ready for work or during summer months when irrigation needs increase, the demand for water can exceed the immediate supply from treatment plants. Storage tanks help mitigate this situation by allowing for sufficient water pressure and flow rates to be maintained, which is essential for public health and safety.

In contrast, other functions such as recycling wastewater, enhancing water quality through filtration, and managing chemical additives do not represent the core purpose of storage tanks. They typically involve different systems and processes that focus on treatment or process management rather than the immediate management of supply and demand in distribution.
