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.

Natural Gas >> Cross Bores

What is M.U.D. doing about cross bores?

At the beginning of 2011, M.U.D. began inspecting the sewer laterals of all properties in an area where we installed gas pipes using directional boring. M.U.D. construction crews are also placing pink warning tags on the front doors of all homes in areas where direction boring installations are being done. We also compiled a list of all the areas where we installed gas pipes using directional boring in the past. We are in the process of inspecting these areas as well; however it will take several years to complete all of the necessary inspections.

How is M.U.D. performing sewer lateral inspections?

M.U.D. is currently using several contractors to visually inspect sewer laterals. One type of contractor inserts a small camera into a home’s sewer lateral and pushes the camera from the home to the city’s mainline sanitary sewer. The camera is typically inserted into the sewer lateral through a basement cleanout, rooftop vent pipe, or floor drain.

What should I do if a contractor contacts me regarding a sewer lateral inspection?

M.U.D. currently has contracts with Backlund Plumbing and Roto-Rooter to perform sewer lateral inspections. It is possible one of these two contractors will call to schedule an inspection. These two companies will also be placing orange information tags on homes where inspections are needed. Please remember, these inspections are free of charge so our contractors will not attempt to charge any residents or up sell any of their other services while doing work for M.U.D.

If you have any questions or concerns when contacted by Backlund Plumbing or Roto-Rooter or if any other contractor contacts you on behalf of M.U.D., immediately call us at 402.554.6666 prior to letting anyone inside your home.

How do I know if my sewer lateral has a blockage?

A sewer lateral blockage has different characteristics than a standard drain blockage. A drain blockage will cause one drain to run slowly or not at all while other drains in a house flow freely. A drain blockage could also occur anywhere in a house. A sewer lateral blockage will cause multiple lower level drains to run slow or back up. Please note, this will be most apparent on the lowest level of the home and not on any levels above that.

Water >> General

How often is water tested?

The water is tested throughout the treatment process. After the treated water leaves our plants, we test it daily throughout the distribution system. In fact, we conduct a minimum of 300 tests a month for bacteria alone.

Every test is conducted in strict accordance with every requirement set by EPA and Nebraska Health and Human Services.

Do you perform taste and odor tests on water samples?

Odor tests are performed a minimum of once a month on both the Missouri River water and on tap water. We also have a special device in the lab which we use to monitor the odor of the tap water on a 24-hour basis. The only time the taste of the water is checked is if there has been a complaint about the taste by a customer. We then will obtain a sample of that water and check its taste. During spring runoff, we check odor daily or as often as necessary.

Why is carbon added to the water?

Carbon removes tastes and odors from the water. The tastes and odors are caused by decaying vegetation and other wastes that are produced during the spring runoff. Carbon also removes pesticides such as atrazine and volatile organic compounds.

How much fluoride is in the water?

Our water sources have naturally occurring fluoride levels in the range of about 0.4 to 0.5 parts per million; which can also be stated as milligrams per liter. We add fluoride to bring the tap water concentration to about 0.8 parts per million.

Will I lose the benefits of fluoride in my drinking water if I install a home treatment device?

Certain types of home treatment devices will remove 85 percent to more than 95 percent of all the minerals in water, including fluoride. These are reverse osmosis, distillation units and deionization units (not water softeners-they leave fluoride in the water). If you use one of these types of devices, consult with your dentist about fluoride and possibly your doctor about iodine supplements.

What is Cryptosporidium?

Cryptosporidium is a protozoan parasite and one-celled animal too small to be seen without a microscope. It's common in surface waters (lakes and rivers), especially when these waters contain a high amount of sewage or animal waste.

Cryptosporidium can cause symptoms that include diarrhea, nausea, stomach cramps or all three. Because many other conditions can produce these same symptoms, a special laboratory test is needed to find out whether Cryptosporidium is the cause.

The District monitors the raw and treated water at both treatment plants for Cryptosporidium with monthly tests. It has never been found in our treated water.

Are there any special precautions people with cancer or AIDS should take before drinking/using M.U.D. water?

Immuno-compromised people-such as those with cancer undergoing chemotherapy, people with HIV/AIDS or other immune system disorders, some older adults and infants-may be particularly at risk from infections. These people should get advice about drinking water from their health care providers. For more information, contact the EPA Safe Drinking Water Hotline, 800.426.4791 or go to their website, (www.epa.gov/safewater).

Why do pipes build up scale?

Usually a thin coating of calcium carbonate (scale) helps to prevent the corrosion of pipes. Scaling may occur in the hot water pipes due to precipitation of some of the hardness found in the water. At the Florence Water Treatment Plant approximately 35 percent of the hardness is removed from the raw Missouri River water before it is put into our distribution system.

Are radioactive wastes detectable in the Missouri River from OPPD's nuclear plant at Fort Calhoun?

Radioactive wastes from OPPD's nuclear power plant have not been detected.

What is hard water?

Hardness in drinking water is caused mainly by two minerals -- calcium and magnesium. If calcium or magnesium is present in your water in substantial amounts, the water is said to be hard because making a lather or suds for washing is (hard) difficult to do. Water containing little calcium or magnesium is called soft water.

I heard we have high levels of iron in our water. I noticed a slight build-up of rust on my plumbing fixtures and had rust disease on my grass. What is being done to prevent this from happening?

M.U.D. water has negligible amounts of iron so the water should not be causing the problem. We lime-soften the water to about 170 milligrams per liter, which is the same as 10 grains per gallon of hardness. This is soft enough to be suitable for all home uses.

During lime-softening, the lime (calcium) added is removed from the water along with calcium and magnesium (hardness) naturally present in the water. (In home softeners, sodium is added to the water in exchange for the hardness removed.)

M.U.D.'s water will deposit small amounts of calcium carbonate in your pipes and on fixtures. It is a tan color. This is good because this means the water does not dissolve chemicals, such as copper, from your plumbing.

Is water with chlorine safe to drink?

Many tests have shown that the amount of chlorine found in treated water is safe to drink, although some people may object to the taste. Chlorine in drinking water does not cause diarrhea in humans or animals.

I hear aluminum is used to treat drinking water. Does it cause Alzheimer's disease?

Aluminum-containing chemicals, called alum or aluminum sulfate, are used to treat most surface waters. These chemicals trap dirt and then form large particles in the water that settle out so very little aluminum stays in the water.

Considerable publicity was given to some studies suggesting that more people were diagnosed with Alzheimer's disease in areas where drinking water contained small amounts of aluminum. According to most Alzheimer's disease experts, these reports are not accurate.

Aluminum is a natural chemical that occurs in many foods, including tea. Even if you live where the level of aluminum in drinking water is much above average, your intake from food would be about 20 times your intake from drinking water.

Aluminum is not regulated by the EPA because there is no reliable scientific data that shows it's dangerous.

Does lithium in M.U.D. water prevent heart attacks?

We have no statistical data on this assertion.

What causes air bubbles in my glass of water?

Air in water occurs naturally and is released when cold water is warmed by sitting in household plumbing lines or hot water heaters. Air also can occur in water following routine repairs to water lines. There is no health risk associated with air in water.

What does potability mean?

Potability means the quality of being drinkable.
