How does the portable sink work?

The portable sink works by utilizing a self-contained system that provides both water supply and waste management. It consists of a water tank that stores fresh water and a separate tank for collecting wastewater. When the sink is turned on, the fresh water is pumped from the tank through a faucet or tap, allowing users to wash their hands or perform other tasks. The wastewater then flows into the gray water tank, which can be easily emptied and cleaned later. Some portable sinks also include features like a foot pump or a hand sanitizer dispenser for added convenience. Overall, the sink's design ensures hygienic handwashing in any location where traditional plumbing is unavailable or impractical, making it suitable for various events, outdoor activities, or temporary construction sites.
