How do you build a small desalination plant?

To build a small desalination plant, start by selecting a suitable location with access to seawater or brackish water. Next, choose a desalination technology, such as reverse osmosis or distillation, based on your budget and water quality needs. Then, design the plant layout, ensuring it includes pre-treatment, the desalination process, and post-treatment facilities. Finally, secure necessary permits, source materials and equipment, and construct the plant while considering environmental impacts and energy efficiency.
