Where Does Used Water Go In A Portable Sink?

Used water drains into the greywater tank, a separate wastewater storage tank.

In a portable sink, used sink water drains into a separate and larger wastewater storage tank, also known as a greywater tank. This tank collects the water that has been used for handwashing or other activities, preventing it from contaminating the separate freshwater supply tank. The wastewater tank should be monitored regularly to ensure it is not too full. When the greywater tank reaches capacity, it should be emptied and cleaned according to the manufacturer's guidelines or local regulations. The collected wastewater should be disposed of responsibly, typically draining into a designated sewer system or approved disposal site. PortableHandwashing.com carries the largest variety of portable sinks from all the major manufacturers, and our Experts will help you select the right sink for your needs.
