Desalination reservoirs can be either covered or uncovered, but the choice depends on location, climate, and water quality requirements. In many cases, covered reservoirs are preferred because they offer better protection for treated water. A cover helps keep out dust, debris, animals, and rainfall, all of which could affect water quality. It also reduces sunlight exposure, which limits algae growth, and helps maintain disinfectant levels such as chlorine for longer periods.
Uncovered reservoirs are sometimes used when large volumes of storage are needed and covering the surface is not practical or cost-effective. These are more common in areas with dry climates, where the risk of contamination from runoff or organic matter is lower. However, uncovered reservoirs require more active monitoring and maintenance to control issues like evaporation, algae growth, and potential contamination.
