Sewage Signs | Sewage Warning Signs

Place an obvious warning near sewage discharge areas, septic fields, and treatment facilities, so no one ever tries to go swimming. Sewage warning signs are available in a variety of sizes to prevent accidental exposure to unsafe water.

• Premium 3M inks, printed on rustproof aluminum with an outdoor durability of over 10 years.
• Resistant to chemical spills and high temperatures, so these won't fade or erode — a favorite of our many treatment facility buyers.
• Use different headers or signal words to indicate the severity of the hazard or situation.

Caution Sign : Septic Spray Field With Symbol

Part #: K-9726 18" x 12" Heavy-Duty Aluminum Sign, 63 mil Verified Purchase

Winner, Winner, Chicken Dinner

This Sign is so great. The best sign ever made. The Yellow color and the Black lettering. To die for! Such an unbelievable contrast! The holes at the top and bottom are just the right size for many screws or other hanger choices. The word CAUTION at the top and the big exclamation point in the center really lets people know that they better sit up and pay attention or they are going to get really soaked with some shit water! Whoever chose the colors for this sign should be promoted! And the Aluminum it is made of is lightweight yet strong! 63 mils thick! You will be tempted to use it for other things like a bridge, but DON'T! Its true calling is definitely a caution, shit water sign!!
