Potable Water Sign

A potable water sign identifies water that is safe for human consumption - drinking, cooking, and brushing teeth. A non-potable water sign warns that the water source is not safe for drinking due to contamination, chemical treatment, or mechanical use only. We carry both types so facilities can clearly communicate the drinking safety status of every water source on their property.

Yes. OSHA 1926.51 requires that non-potable water outlets on construction sites be clearly marked to prevent workers from using them for drinking or washing. Our non-potable water signs meet this requirement and are available in durable aluminum and adhesive formats for immediate posting on hose bibs, tank outlets, and any non-drinking water supply on active construction projects.

Yes. Our customizable potable and non-potable water sign templates allow you to add a source name, water quality test date, contact information, or specific usage instructions. Custom water safety signs are especially useful for campgrounds, outdoor recreation facilities, and utility sites where multiple water sources need to be clearly distinguished for guests and workers.

For outdoor water sources, aluminum is the best material for potable and non-potable water signs. Our aluminum signs are rust-proof, moisture-resistant, and designed to withstand the wet conditions common near outdoor water supply points. They maintain clear, legible print through years of outdoor exposure and are available in pre-drilled formats for post, fence, or wall mounting.
