Permits are almost always required to construct desalination reservoirs, since they are part of public water infrastructure and can affect land, water resources, and the surrounding environment. Most projects require environmental permits to ensure the reservoir will not harm local ecosystems, groundwater, or nearby communities. This usually involves an environmental impact assessment (EIA) or similar review. Construction permits are also necessary, covering engineering design, safety standards, and materials used for linings or covers.
In some regions, water authority approvals are required to confirm that the reservoir meets drinking water storage regulations, including protections against contamination and compliance with public health standards. Other permits may apply depending on the site. For example, building in a coastal zone may require coastal management or flood protection permits, while reservoirs near protected habitats might need special clearances from environmental or wildlife agencies.
