Underground Service Alert, or USA, is a national network that tracks all underground water pipes, gas lines, electrical conduits, television cables, etc. Because these lines and pipes can be damaged by anyone digging underground, Irvine Ranch Water District ensures that all of its pipes and other underground equipment are listed in the USA database. IRWD also contacts USA before doing any excavating to ensure that we will not disturb any other service lines when conducting our construction and repair work.

Any homeowner or contractor who plans to dig ANY excavation should contact USA's Dig Alert toll free number at 1(800) 227-2600 at least two working days before you plan to dig!
