Protecting a Septic System During and After a Flood

When a home or the area surrounding it floods, the septic system is at risk of becoming waterlogged. This could be from a leak in the lid, rising groundwater that enters into the system, or an over-saturated drainfield that can't properly drain. A flooded septic system may lead to sewage backing up into the home and cause serious problems for the homeowner. 

Septic tanks may not always experience damage just because there is flooding, but any existing leaks in the system will allow floodwater, silt, and debris to enter the system. This presents a big problem since the extra dirt and debris can cause clogging. Extra water entering the septic system can also cause the floating solids to rise up and plug the pipes. The U.S. Environmental Protection Agency has information on what to do after a flood to ensure your septic system is protected. Below we have summarized this information with a list of dos & don'ts:

Septic System Flooding Dos & Dont's

This video provides some additional tips for how to avoid septic tank flooding and what to do if your system does flood:

Following these tips will help septic system homeowners to be prepared in the event of a flood and protect the septic system from further damages. If you need more specific advice or assistance with your septic system, contact your local health department for a list of septic system contractors in your area.

Sanitary Sewer Overflows

Properly designed, operated, and maintained sanitary sewer systems are meant to collect and transport all of the sewage that flows into them from a community into a wastewater plant for treatment. Sanitary sewers are the things we flush, pour down drains, etc. There are regulations that say stormwater and sanitary sewers are to be completely separate, but in many older, large communities they run together and can overload a wastewater plant.

We have 810 resources (and counting) on Sanitary Sewers in our Documents Database that provide valuable information on this topic. You can search for documents about the development process for publicly owned treatment works (POTW), benefits of protecting your community from sanitary sewer overflows, how to develop a collection system maintenance program, combined sewer overflow management, and many other useful guides that will help you to deliver safe and clean water to utility customers.

Safety Tips for Water Operators

According to the National Safety Council, accident rates continue to be high for the water industry, even when compared with other high-risk fields such as construction and mining. It's important for water operators to be informed on accident prevention practices and safety procedures to protect themselves from the hazards associated with this essential role.

Surprising Facts About Septic Systems

Septic systems treat and dispose of wastewater for locations that public wastewater systems do not service. Many homeowners living with a septic system don't know much about it other than the fact that they have one. If more homeowners learned the ins and outs of their septic systems, they would have the ability to prevent issues before they arise. This article from Dano's Septic (excerpted below) reveals some surprising facts about septic systems.

Every home has a different pumping schedule

• Septic systems must be maintained regularly (at least once every 3-5 years) but the exact frequency depends on some factors like tank size, system age, and usage habits.

You can't flush everything

• Flushing items like pet waste, feminine products, and even floss can interfere with the system's ability to break down waste and create the need for premature pumping of the system.

Drain cleaners can be dangerous

• Chemical drain cleaners can mess with the balance of your septic tank and create problems down the road. Avoid this "quick fix" whenever possible and call a professional to help unclog any drains.

The system involves much more than just the toilet and tank

• Every single sink, tub, and pipe in the home is connected to the septic system. Even the garbage disposal can affect how the system functions, so it is important to pay close attention not only to what is being flushed down the toilet, but also what is poured down the drain.

Your system can affect the groundwater

• Septic systems have the potential to contaminate the groundwater since whatever enters the septic tank will eventually reach the drain field and seep into the ground.

Drain fields can flood

• This is one of the biggest concerns related to septic systems. When the drain field floods, it quickly contaminates the property with wastewater. Try to practice water conservation as often as possible and schedule a professional inspection annually to prevent this.

Maintaining your system will extend its lifespan

• Septic tanks can last for decades with consistent upkeep but eventually they will need to be replaced. Prioritize repairs and maintenance for the septic system to ensure the longest lifespan possible.

Radioactive Contaminants in Water

Most water sources have very low levels of radioactive contaminants, most of which are naturally occurring, although contamination from human-made nuclear materials can also occur. Most radionuclides are at levels that are low enough to not be considered a public health concern. At higher levels, long-term exposure to radionuclides in drinking water may cause cancer. In addition, exposure to uranium in drinking water may cause toxic effects to the kidneys. Radiation found in sewage sludge and the ash from its incineration may be from Nuclear Regulatory Commission licensees, industrial discharges, and TENORM.

We have 100 resources (and counting) on Radionuclides in our Documents Database that provide valuable information on this topic. You can search for documents on the management of radioactive residuals from drinking water treatment, approved analytical methods for monitoring radionuclides, uranium as a drinking water contaminant, federal regulations on the disposal of residuals containing radionuclides, and many other useful guides that will help you to deliver safe and clean water to utility customers.

Public Notification & Emergency Communication

Public Notification Rule is intended to ensure that consumers will always know if there is a problem with their drinking water. These notices immediately alert consumers if there is a serious problem with their drinking water that may pose a risk to public health. They also notify customers if their water does not meet drinking water standards, the water system fails to test its water, or if the system has been granted a variance (use of less costly technology) or an exemption (more time to comply with a new regulation.) Consumer Confidence reports (CCRs) are an annual report of the status of the drinking water at a facility that are also required. However, CCRs do not necessarily report problems, but a status.

We have 731 resources (and counting) on Public Notification in our Documents Database that provide valuable information on this topic. You can search for documents about how states are responding to health advisories for water systems, ways to prepare for a drought related water shortage, advice for working with news media, boil water advisories during natural disasters, and many other useful guides that will help you to deliver safe and clean water to utility customers.
