Does Home Insurance Cover Septic Problems? What You Need to Know

Septic tanks are underground wastewater treatment systems that are commonly used in rural areas without centralized sewer systems.

They are responsible for collecting and disposing of household waste in a safe and sanitary manner.

However, septic tanks can also be prone to various problems, such as leaks, backups, overflows, cracks, and damage from external factors.

These problems can cause unpleasant odors, health hazards, environmental pollution, and costly repairs.

If you own a septic tank, you may wonder if your home insurance policy covers any damage or leakage from your septic system.

The answer is not straightforward, as it depends on several factors, such as the cause of the problem, the extent of the damage, and the type of coverage you have.

In this article, we will explain how home insurance works for septic tanks and what you can do to protect yourself from potential septic issues.

When does home insurance cover septic problems?

Home insurance policies typically include coverage for “other structures” on your property, such as fences, sheds, pools, and septic tanks.

This means that your septic tank is covered by your home insurance in cases of sudden and accidental damage that is caused by a covered peril.

Covered perils are specific events that are listed in your policy, such as fire, lightning, windstorm, hail, explosion, vandalism, theft, falling objects, volcanic eruption, and weight of snow or ice.

For example, if a tree falls on your septic tank during a storm and cracks it open, your home insurance policy may pay for the repair or replacement of your septic tank, as well as any damage to your home or personal property caused by the septic leak.

Similarly, if a fire damages your septic tank and causes it to overflow into your basement, your home insurance policy may cover the cost of cleaning up the mess and restoring your home.

However, there are some limitations and exclusions to this coverage.

First of all, most home insurance policies limit the coverage for other structures to 10% of your dwelling coverage amount.

For instance, if your home is insured for $300,000, your other structures coverage may be up to $30,000.

This may or may not be enough to cover the full cost of repairing or replacing your septic tank, depending on the severity of the damage and the type of septic system you have.

Secondly, home insurance policies do not cover any damage that is caused by neglect or lack of maintenance.

This means that if your septic tank fails due to normal wear and tear, corrosion, rusting, aging, or improper installation or operation, you will not be able to file a claim with your home insurance company.

Likewise, if you cause damage to your septic tank by flushing chemicals, solids, or oils down the drain; driving over the tank; not having proper drainage; or not taking care of tree roots that grow into the tank; you will be responsible for the repair costs out of your own pocket.

What about water backup coverage?

Another common problem with septic tanks is water backup.

This occurs when water or sewage from your septic system backs up into your home through drains or toilets.

This can cause significant damage to your floors, walls, furniture, appliances, and personal belongings.

It can also create health risks due to exposure to bacteria and pathogens.

Water backup is not covered by standard home insurance policies.

However, you can purchase an optional endorsement called water backup coverage that can protect you from this type of loss.

Water backup coverage is a common home insurance rider that covers the cost of repairing the damage caused by water or sewage backup from your septic system or sump pump.

It also covers the cost of mold remediation and other preventive measures to avoid further damage.

Water backup coverage is usually sold as a separate limit on your policy.

The amount of coverage you can buy varies depending on your insurer and location. Some insurers offer water backup coverage as low as $5,000 and as high as $50,000.

The cost of water backup coverage also depends on several factors, such as the age and condition of your home and plumbing system; the size and type of your septic system; and the risk level of water backup in your area.

Water backup coverage is highly recommended for homeowners who have a septic system or a sump pump on their property. It can provide peace of mind and financial security in case of a water backup disaster.

How to take care of your septic tank

The best way to avoid septic problems and potential claims is to take good care of your septic tank.

Regular maintenance and inspection can help prevent costly repairs and extend the lifespan of your septic system.

Here are some tips on how to take care of your septic tank:

  1. Have your septic tank pumped every three to five years by a licensed professional.
  2. Have your septic system inspected at least once a year for any signs of damage or malfunction.
  3. Use water efficiently and avoid overloading your septic system with excess water.
  4. Avoid flushing or pouring anything that can clog or harm your septic system, such as grease, oil, chemicals, paper towels, feminine products, diapers, or wipes.
  5. Keep trees and shrubs away from your septic tank and drain field to prevent root intrusion.
  6. Do not drive or park over your septic tank or drain field to avoid soil compaction and damage.
  7. Install risers, filters, and alarms on your septic tank to make it easier to access and monitor.


Home insurance can cover septic problems in some situations, but not in others.

It is important to understand the terms and conditions of your policy and what it does and does not cover.

You should also consider adding water backup coverage to your policy if you have a septic system or a sump pump on your property.

Finally, you should perform regular maintenance and inspection on your septic system to prevent problems and keep it in good working order..
