Danger Water Main Below Sign – Flooding Property Damage Hazard, Call 811 Before You Dig, 8x12 Rust-Resistant Aluminum Utility Safety Sign by CGAP Safety

A water main is not a “minor oops.” It’s pressurized infrastructure that can turn one bucket bite into a flooding event, a muddy excavation collapse, a road washout, or a property damage claim that instantly dwarfs the cost of basic site marking.

The CGAP Safety “Danger – Water Main Below – Flooding / Property Damage Hazard – Call 811 Before You Dig” sign is a high-visibility warning marker for buried water lines in construction zones, utility corridors, commercial sites, campuses, and municipal right-of-way environments. The bold DANGER header and direct hazard language are designed to interrupt excavation activity early, before crews trench, bore, auger, drive stakes, or set posts in the wrong place.

This sign supports the core behavior that prevents avoidable incidents: pause, confirm, and locate. By pairing the “WATER MAIN BELOW” warning with the Call 811 instruction, it aligns field activity with standard damage-prevention workflows and helps reduce strikes caused by assumptions, missing documentation, or rushed schedules.

Manufactured in 8 x 12 inches from rust-resistant aluminum, this sign is built for long-term indoor/outdoor use where weather, UV exposure, and jobsite wear destroy temporary notices. It’s ideal for mounting on posts, fences, walls, barricades, or near access points where crews and contractors will see it before ground disturbance begins.

Use this sign as part of a broader utility coordination and safe-dig program to reduce flooding risk, protect assets, and keep projects on schedule.

Important: This product is a warning sign only and does not replace required locating/marking practices, safe excavation methods, permits, or local regulations. Always contact 811 and follow applicable procedures before digging.
