Some desalination plants use multiple reservoirs to improve reliability, flexibility, and operational efficiency. Having more than one reservoir allows operators to balance supply and demand more effectively. For example, one reservoir can store water for daily fluctuations in demand, while another serves as a backup in case of maintenance, plant shutdowns, or unexpected spikes in consumption.
Multiple reservoirs also support water quality management. By separating storage, operators can better control disinfection, blending, or remineralization processes and reduce the risk of contamination spreading throughout the system. In addition, having reservoirs at different locations or elevations can improve distribution efficiency, using gravity to move water where it is needed and reducing pumping costs.
