How To Cleanup Sewage Backup In Basement

If you have a sewage backup in your basement, there is an immediate risk to your health and safety. Shut off power and gas to the affected area before entering to do any cleanup. 

Dress in personal protective equipment including goggles, a mask, boots, gloves, and waterproof clothing. Next, prevent the sewage smell from spreading by closing doors and entryways to unaffected areas. Once you identify where the leak originated, use a shop vac, or turn on your sump pump to extract the sewage. Salvaging items in your basement is your next step. Identify all items that came into contact with the sewage and bag and remove them from the basement. 

Remove the debris and sludge left behind from the sewage leak, and treat all surfaces with a mixture of bleach and water. The sewage water may be underneath your flooring so you will likely have to pull up the flooring to know if it is trapped under there. 

Continue to use a wet vac and scrub and rinse all surfaces. To dry out the area, use a dehumidifier, high-powered fans, and remember to open all windows. With any water incident there is the risk of mold and mildew growth. Note any areas where mold may already be taking hold.  While it may be possible to clean up your basement after a limited sewage backup event, consider whether you will be able to complete all of the steps involved without any risk to your or your family’s safety. Sewage contains harmful microorganisms such as bacteria, viruses and protozoa. Direct contact with sewage, or surfaces contaminated by sewage, can result in illnesses such as gastroenteritis.

Instead of risking your health and safety, trust the professionals at HRS. We have been helping homeowners clean up sewage backups for two decades and have the experience and tools to get the job done right. Don’t forget to check your homeowner’s insurance policy to see if sewage backups are covered.

Our IICRC trained sewage backup experts use the latest technology to quickly and safely remove the sewage backup and any affected items. Our goal is to restore your basement to its pristine, pre-sewer backup state.

Why Sewers Back Up

In your basement, sewage backup is most likely caused by four main factors. 

Knowing these factors exist will allow you to identify the problem more rapidly, even if some are beyond your control. Generally, blockages occur when something is blocking your drains or toilets, resulting in a clog. 

Older pipes may have rusted or have cracks in the joints, causing sewer line damage. It’s possible that tree roots have lodged themselves into the underground sewer line. Or there may be a backflow of water into your home if there is a bad storm and the drainage system cannot handle it. 

It’s a good idea to not connect your downspouts and sump pumps to the sewer system. In fact, this could be dangerous during a heavy storm where large amounts of water flow through. Ensure that your downspouts and sump pumps are routed away from your house and that they are free flowing.


Sewage Exposure Dangers

To avoid sewage exposure, you should be aware of the risks you face when you clean sewage in your basement. A sewer backup contains contaminated water full of dangerous bacteria and diseases. 

It is important to understand the risks associated with raw sewage cleanup in the basement. Limit your exposure to the following by contacting HRS. 

Sewer Gas

Gases found in sewer systems include both toxic and nontoxic gases. Household and industrial waste decays in sewers, producing sewer gas. Hydrogen sulfide, ammonia, carbon dioxide, sulfur dioxide, and nitrous oxides are the most toxic components, but methane, carbon dioxide, sulfur dioxide, and nitrogen oxides can also be present.


Sewage backups can happen at any time. When dealing with sewage backups, don’t wait too long to deal with them. As the waste accumulates, bacteria, viruses, and parasites can breed, spread, and potentially cause illness. During a sewage backup, the waste might flow back into your home, so you should be extra careful about cleaning it up. 


Basement sewage backups create ideal conditions for mold outbreaks. For people who are sensitive to mold spores, an infestation can be potentially hazardous. When exposed to mold, people can suffer from a variety of ailments. A person may experience long-term issues such as asthma, psychological issues, and joint pain. Mold toxicity depends on different factors including the exposure period, the area of the infestation, and the level of sensitivity of the person. 

Structural Damage

A wet environment and its resulting mold can damage porous surfaces. You are at risk of having to replace the drywall in your basement in the near future if it was exposed to moisture or sewage backups. Structural defects on one of your load bearing walls could put the occupants of your home at risk. 



What To Do If Your Sewer Backs Up In Basement

Before beginning your sewage cleanup, you have to take care of important details, such as making it clear that no one is to enter the affected area; especially anyone with medical issues and children. Open as many windows as possible, pre-treat the flooded areas with chlorine bleach (see below) and call your insurance company. 

In the sewer water damage restoration process, all water and waste is extracted so work can begin on drying and cleaning to return the basement to its original state. To prevent mold and bacteria from growing, the restoration process needs to be conducted quickly. 

Secure The Area

Make it very clear that no one is to enter the affected area. If you have children or pets, keep them away from raw sewage backup to prevent them from getting sick. 

Separate contaminated areas from non-affected areas by closing doors. By doing so, the probability of tracking sewage debris and water throughout the house is reduced. Additionally, this step can prevent airborne contaminants from spreading. 

Open Up Windows & Circulate The Air

You can circulate air in the basement by opening windows or vents if the raw sewage smell is overwhelming. The top of the stairs can also be equipped with fans to provide fresh air. To prevent yourself from getting sick from the smell, take frequent breaks from the basement to limit your exposure.

Treat Flooded Areas With Chlorine Bleach

Use a small amount of chlorine bleach to pre-treat the flood areas after you dry your basement. By doing so, you are creating a disinfectant barrier that stops the spread of sewage-borne bacteria.

Alternatively, you could wash everything contaminated by sewage with a mixture of bleach and water. You can use spray bottles to wash walls and large surfaces. Repeat the process again after the bleach has dried to ensure you’ve killed mold and bacteria. 

Call Insurance Company

In case your policy covers sewage backup, explain the situation. Otherwise, inquire about your current water damage coverage. A homeowner’s policy covers damage caused by a sudden or accidental event. However, damage due to improper maintenance is not generally covered by your insurance. If you have items damaged by water or mold, note these for insurance purposes.

Depending on the steps you’ve taken to reduce the chances of flooding, your insurance may or may not cover water in your basement. Your insurance company must be contacted in case of a sewer backup since it is considered preventable with maintenance.

How To Clean Up Sewage In A Basement

Fixing basement water damage as soon as possible is imperative to save your foundation and belongings. 

You must determine which items and goods have come into direct contact with sewage water and contaminated debris. This is even more difficult in a finished basement.

The cleanup process for a sewage backup in a basement can be pretty messy, so you need to use PPE, or personal protective equipment. You also need to find out where the leak is and stop it, then remove affected items, repair and restore any affected items, and look for evidence of mold. 

Even though you can clean up sewage on your own, it is not recommended because of the associated health risks. Here are some steps that show how to clean up sewage in basements.  

Use Protective Equipment

You will be exposed to highly contaminated water while doing sewage cleanup, so put on protective gear before you start. While cleaning up after a sewage backup, you want as little skin exposed as possible. During cleanup, make sure you wear rubber boots, long sleeves, and rubber gloves. Protect your face from sewage splashes by wearing a ventilator and goggles. In addition, take a shower, and clean thoroughly after you have completed the process. 

Identify Source Of Leak

When a clog is in your sewer line, sewage becomes backed up with no way to escape. Or your home can be flooded with sewage if your sewer line breaks or leaks, especially in your basement. Inappropriately flushed items, damaged pipes, or even tree roots that are drawn to underground water sources, can cause a blockage.

As sewage and water back up inside a blocked pipe, pressure is placed on the walls of the pipe. Eventually, pressure builds up to an unmanageable level, and the seals and the sides of the pipe become damaged or leak. Your basement now has sewage backing up, endangering your safety. 

Remove All Affected Surfaces that Cannot Be Cleaned

The aftermath of a sewer backup is difficult to clean and disinfect – carpets, walls, and furniture have all been flooded with wastewater. Be sure to get rid of any materials saturated with sewage. Paper, carpeting, and fabric furniture may need to be thrown out. With push brooms and shovels, remove the sludge and debris. If in doubt, throw the sewage tainted items out. 

Repair & Restore All Contaminated Items

Repair and restore contaminated items after letting the basement dry for several days after disinfection. Identify and repair damaged drywall, as well as replace warped baseboards. Before returning furnishings and belongings to the basement, ensure they are completely dry and sanitized. Renovations will vary depending on the area affected and the amount of sewage involved. 

Check For Mold

An untreated sewage backup in the basement can lead to an outbreak of unhealthy mold. It’s important to remove any traces of moisture and contaminants from the mess as well, but fungal growth can continue even after you clean it up. When your basement has flooded, examine it for mold regularly. 


How To Remove Sewage Smell

You should inspect your drains, vents, and pipes if your basement smells like sewage after you’ve cleaned it thoroughly. If you notice a sewage smell in basements, you first have to identify the offending source of the smell. Here are some ideas on how to remove sewer gas smell, which can be as simple as inspecting the water trap, cleaning the sewer plug, or using a cleaning solution.

Even after cleaning up, there could still be some sewage left behind. The leftover waste can be suctioned up with a shop vacuum. You also might be missing your cleanout plug,  which will cause sewer gas to flow back into your basement, or look for sewage backup in basement floor drains which can cause odor.

Additionally, you should check your appliances, such as your washing machine, HVAC system, toilets, and sinks. Dispose of any remaining water as soon as possible to help get rid of sewage smell in basements. Make sure that you contact HRS right away if the odor does not disappear or if mold is visible. 


What To Do If You’re Exposed To Raw Sewage

When dealing with a sewer backup in your basement, there are several health risks you should be concerned with. , especially if you plan on resolving the issue yourself. 

The simplest of jobs requires personal protective equipment. Make sure you wash your hands thoroughly, refrain from touching your eyes, mouth, nose and ears, and dispose of contaminated clothing. Remember to take a hot shower and call your physician if you experience any ill health effects after you have cleaned your sewage infested basement. Below we break down these safety protocols for you. 

Wash Hands Thoroughly

Whenever you take a break and after every cleanup shift, scrub your hands thoroughly with an antibacterial soap. Don’t forget to scrub under your fingernails as well. 

The risk of becoming ill from waterborne diseases increases when you don’t wash your hands. 

Refrain From Touching Eyes, Mouth, Nose & Ears

Keep your gloves away from your face to prevent the spread of bacteria. If you must touch your mouth, eyes, nose or ears, do so only after removing your contaminated gloves.  If you do not heed this advice, you run the risk of contracting salmonella and encephalitis. 

Dispose Of Contaminated Clothing

At the end of each cleanup session, bag your work gear securely, store it in a safe place, and take a shower. Especially when it comes to laundry, avoid mixing contaminated clothes with regular ones. 

Shower Immediately

Once you have disposed of contaminated clothing, make sure that you take a hot shower immediately and use plenty of antibacterial soap, washing yourself thoroughly. 

Contact Doctor If Feeling Ill

During a cleanup, if you start to feel ill, contact your doctor. When you think your health is affected by exposure, consult your doctor. In addition to diphtheria and tetanus vaccinations, the doctor may recommend a visit to the nearest emergency room. 

Beyond the sewage, the resulting mold may also be a health hazard. Mold colonies evolved to use mycotoxins to kill each other, but they also turn out to be harmful to humans.
