Common maintenance issues with desalination reservoirs usually relate to protecting water quality, structural integrity, and reliable operation. One frequent challenge is biofouling, where algae or microbial growth develops, especially in uncovered reservoirs exposed to sunlight. Operators manage this with disinfection, circulation, or periodic cleaning. Sediment buildup is another concern, as particles introduced through inflows or from the surrounding environment can accumulate on the reservoir floor. Over time, this reduces effective storage volume and may affect water quality if not removed.
Structural issues can also arise. Liners and protective coatings may degrade or crack, leading to leaks or contamination risks, while in coastal environments, equipment such as pumps, pipes, and valves can suffer from corrosion due to exposure to salty air. Operational challenges include evaporation losses in hot, dry climates and maintaining consistent disinfectant levels throughout the reservoir, especially in large systems with uneven circulation. Security and access control are also ongoing concerns, as reservoirs must be protected against vandalism, animals, and accidental contamination.
