Is Your Septic Tank Gurgling? Here’s Why

In the United States, approximately 20 percent of households rely on septic tanks to hold and treat wastewater. If not properly maintained, septic tank can get clogged over time, prompting you to hire septic pumping services — or else, your household will suffer from clogged toilets and drains and pungent smell, and will be exposed to health-hazard bacteria.

How Septic Tank Works

The septic system is composed of the septic tank itself and a drain field.

The tank (which is an underground container made of concrete, plastic, or fiberglass) has two pipes. The first pipe is called the inlet pipe. Its task is to collect wastewater and transport it into the tank. The outlet pipe, on the other hand, is responsible for discharging the preprocessed liquid waste into the drain field.

Inside the tank, wastewater is held long enough to allow solid and liquid wastes to be separated from each other. Solids settle down in the bottom as sludge; the liquids float atop of the sludge as scum.

Once the pretreated water flows out of the tank, it is discharged and ultimately percolates into the soil. The soil acts as a natural filter that removes harmful bacteria and viruses. The remaining liquids then spread through watercourses.

The system is also equipped with drain vents to help remove sewer gas from the pipes

As the tank and the whole system itself play a crucial role in treating household wastewater, it needs to be cleaned on a regular basis. Smaller tanks require septic pumping services within one year.

Should You Be Alarmed When You Hear Gurgling Noises?

Over time, you may hear gurgling noises when you flush your toilet or you run the water. Should it make you be alarmed? The straight answer is yes. It’s a tell-tale sign that something is wrong with your septic or plumbing system. But for this matter to be effectively addressed, the cause of the noise should be identified.

Here are some reasons why you hear alarming gurgling:

Your septic tank is full. A full-house septic tank makes it hard for wastewater to flow out properly. Septic pumping services are needed to free your tank with the waste causing the damage.

Your drains are clogged. Gurgling noises can also be caused by clogged plumbing drains. Blocked drainage slows down the transport of wastewater into the tank.

Your drain vents are broken. If your system’s drain vents are not properly working, it can also produce a gurgling sound that can loudly be heard when you shower or flush the toilet.

Your sewer pipes are blocked. Like a clogged drain, pipes that are blocked with solid wastes can also make unwanted, oft-annoying sounds.

Your drain field is damaged. If there’s something wrong with your drain field, it can affect the whole system process. As wastewater is not properly discharged from the field, consequences like gurgling noises can be observed.

When checking your septic system, look at the ground where the tank and the drain field are located. Normally, the ground should not have water around it, or it should not feature overly green and soggy grasses. If they look otherwise, it’s high time for you to call for professional help.
