Smell gas? Move fast.

Because natural gas is colorless and has no scent, we add a strong odorant that smells like rotten eggs to help you detect a possible natural gas leak.

If you suspect a leak, call 1-800-ALLIANT (800-255-4268) immediately. We will investigate for free.

Additional tips

Individuals with a known inability to smell should consider purchasing a natural gas detector. Some people may not be able to smell the natural gas odor because it is being masked or hidden by other scents, such as cooking or chemical odors.

Olfactory fatigue is another reason people might not be able to smell a gas leak. This is the temporary inability to distinguish an odor after a prolonged exposure to it. In addition, certain conditions in pipes and soil can cause odor fade (which is loss of odorant) making it undetectable by smell.

Take ownership of privately buried piping

Some homes and businesses have privately buried natural gas or fuel lines that run to an unattended garage, grill or pool. These lines are not installed or maintained by Alliant Energy, and customers are responsible for them. We are responsible for the gas line leading up to your meter, but any additional lines are your responsibility. 

Customers must maintain, operate and know the location of buried lines. A qualified technician should regularly inspect it for leaks. If the piping is metallic, inspect it for corrosion. Repair if unsafe or shut off the flow of gas. Prior to excavating, have the pipe located and marked. Excavating performed near the pipe should be done by hand.

Digging for an outside project? Follow these three rules:

  1. Call 811 before you dig. This is the national phone number that initiates the process of locating and marking the underground utility lines in your yard or at your job. Call 811 at least two business days before you dig.
  2. Wait the required time for utility lines to be marked. One Call Center personnel will notify us to mark the approximate locations of buried gas or electric lines with high-visibility safety paint and/or flags. There is no charge for this locating service.
  3. Respect the marks or flags and dig with care. When you start digging, stay at least 18 inches away from the marked lines. Hand dig with extreme caution if you must excavate within the safety tolerance zone.

    Call 1-800-ALLIANT if your equipment or tools contact our underground pipelines or electrical lines. Even minor damage such as nicks, scratches, cuts, scrapes, dents and gouges can result in pipeline failure, electric shock or a major incident in the future if not properly assessed. If you hear blowing gas, which is a more serious problem, call 911 immediately from a safe location.

Take care of your appliances and equipment

Use a broom to keep gas service equipment clear during the winter. Kicking or using a shovel could damage the equipment.

A qualified professional should check your gas appliances annually. Inspections keep gas appliances safe and efficient, and reduce risks of carbon monoxide poisoning.

Vents for gas appliances must be cleared following a major snow or ice storm to enable proper venting and prevent carbon monoxide accumulation.

Do you know where utility lines are buried in your yard?

Communities have many different buried utility lines, including natural gas pipelines, electrical, water, cable and internet lines.

Homeowners and contractors who don’t call 811 before they start digging or excavating are the leading cause of pipeline accidents.

A call to 811 will send a professional locator to your property to mark a natural gas pipe or other utility-owned lines in the ground. Locators will not mark privately owned fuel lines, like those running to a garage, pool or fireplace.

How natural gas gets to you

Natural gas comes from the earth. It travels to your community through underground transmission pipelines. Pipelines are a safe and reliable way to transport natural gas.
Inside your community, the gas travels through pipelines called mains. Mains are often buried under or along streets. From there, a smaller service line brings the gas to your meter. Service lines are buried in yards.

After the gas passes through a meter, it belongs to the customer. Customers are responsible for installing and maintaining the piping that natural gas flows through to reach appliances and equipment.
