What is an Emergency?

Gas leaks, odor of gas, damaged lines, carbon monoxide symptoms and water main breaks are all considered emergencies.

If you smell gas, do not attempt to locate the leak. Instead, leave the house or building right away. Do not use any electrical switches, appliances, lights, telephones, or mobile devices, as an electrical charge could create a spark. When you are in a safe place, call M.U.D.'s emergency hotline at 402.554.7777 or 9-1-1.

If someone is showing symptoms of carbon monoxide poisoning, call 9-1-1 immediately. Symptoms are like the flu.

If you have a water-related emergency, call 402.554.7777. Our personnel are ready to assist you 24/7. When in doubt, call us immediately.


Las fugas de gas, el olor a gas, las tuberías de gas dañadas, los síntomas de monóxido de carbono y roturas en las tuberías principales de agua son consideradas emergencias.

Si huele a gas, NO trate de localizar la fuga/escape. Al contrario, abandone la casa o el edificio inmediatamente. No utilice los interruptores eléctricos, electrodomésticos, luces, teléfonos o equipos móviles, ya que una carga eléctrica podría provocar una chispa. Una vez que se encuentre en un lugar seguro, entonces llame a la línea directa de emergencia de M.U.D. al 402.554.7777 o al 9-1-1.

Si alguien tiene síntomas de envenenamiento causados por el monóxido de carbono, llame al 9-1-1 inmediatamente. Los síntomas son como los de la gripe/catarro.

Si tiene una emergencia relacionada con el agua, llame al 402.554.7777. Nuestro personal está listo para ayudarle, 24/7. Cuando dude o crea que hay una emergencia, llámenos de inmediato.

Will an excess flow valve protect against all types of gas leaks?

How long will an excess flow valve last?

How do I know if an excess flow valve can be installed at my house?

How do I know if I already have an excess flow valve (EFV)?

Federal law did not require EFVs to be installed on newly constructed homes until June 2008. If your home was built prior to June 2008, you most likely do not have an EFV installed on the service line to your home. Customers who want to have an EFV installed on their service line that was installed…
