Desalinated water is usually stored before distribution to make the supply system more reliable, flexible, and efficient. One of the main reasons is that water demand changes throughout the day, while desalination plants work best when they run at a steady output. By storing treated water in reservoirs, operators can smooth out this mismatch, this keeps the plant running continuously while meeting peak demand from storage.
Storage also provides a safety buffer. If the plant needs to shut down for maintenance, power outages, or unexpected technical issues, the reservoir ensures that water is still available for consumers. This backup capacity is especially important in regions that rely heavily on desalination, where alternative water sources may be limited.
