Dealing with clogs and backups in your septic system can be frustrating and expensive. No one wants to deal with slow drains, bad smells, or sewage backups in their yard. What starts as a small issue can quickly turn into a costly repair, system failure, or even damage to your home and property.
Taking simple steps now can prevent bigger problems later. Knowing how your septic system works, watching what goes into it, and scheduling routine pumping can keep it running smoothly for years. The question is—are you taking the right steps to protect your system?
What Is an Anaerobic Septic System?
An anaerobic septic system is a type of waste system often used in rural and suburban homes. It includes a sealed septic tank, either underground or above ground, that collects waste from sinks, showers, and toilets when water goes down the drain.
Inside the tank, solid waste settles at the bottom, while liquid waste stays on top. Bacteria that don’t need oxygen break down the solid waste, which is why it’s called an “anaerobic” system.
The liquid waste moves through underground pipes into a drain field, also called a leach field. Small holes in the pipes let the wastewater slowly drain into the soil, where it gets filtered naturally.
How an Anaerobic Septic System Works?
An anaerobic septic system has three main parts: the septic tank, drain field, and pipes. Waste from your home flows into the septic tank, where solid waste settles at the bottom, and lighter materials like grease and oil float to the top. In the middle, liquid waste, called effluent, stays before moving to the drain field.
Inside the septic tank, bacteria break down the waste without using oxygen, helping to reduce solid buildup. The leftover liquid then flows through pipes into the drain field, where the soil naturally filters and absorbs it. This process safely removes waste from your home while protecting the environment.
Anaerobic vs. Aerobic Septic Systems
In the past, anaerobic septic systems were the most common in the U.S., but today, many homeowners are using aerobic septic systems instead. Here’s how they differ:
1. Oxygen and Bacteria
The biggest difference between the two systems is the presence of oxygen inside the tank. Anaerobic systems do not have oxygen, so they rely on bacteria that can survive without it. These bacteria break down waste more slowly, which is why anaerobic systems need larger drain fields to filter the wastewater properly.
Aerobic systems, on the other hand, use an aerator to add oxygen to the tank. This oxygen helps oxygen-loving bacteria break down waste faster and more efficiently. Because of this, aerobic systems produce cleaner wastewater, which is safer for the environment and can sometimes be reused for irrigation in certain areas.
2. Size
Since anaerobic septic systems break down waste more slowly, they require larger drain fields and more piping to allow wastewater to filter through the soil. This means they take up more space in your yard.
Aerobic systems work more efficiently, so they don’t need as much space. If your yard is small, an aerobic system might be a better option because it requires a smaller drain field. However, since it has extra equipment like an aerator, it may need a separate tank or compartment.
3. Cost
Anaerobic septic systems are more affordable, typically costing between $3,000 and $8,000. Since they don’t require electricity or special equipment, maintenance costs are also lower. Aerobic systems cost more, usually ranging from $10,000 to $20,000.
The added expense comes from the aerator and extra equipment that helps treat wastewater more efficiently. Another thing to consider is that aerobic systems require electricity to power the aerator, which increases operating costs over time. They also need more regular maintenance to keep the system working properly.
What are the Benefits of Anaerobic Septic System?
An anaerobic septic system is a common choice for homeowners because it is simple, affordable, and easy to maintain. Unlike other systems, it works without electricity and uses bacteria to break down waste naturally. These are some reasons why this type of septic system is a good option.
1. Simple and Affordable
Anaerobic septic systems cost less than other types of septic systems. They usually range from $3,000 to $8,000, making them a budget-friendly option for homeowners. Since they do not require special equipment like an aerator, installation is simpler and cheaper.
2. No Electricity Needed
One big advantage of an anaerobic septic system is that it does not need electricity to function. The bacteria inside the tank break down waste naturally, without the help of machines. This means lower utility bills and no worries about power outages affecting your septic system.
3. Easy to Install and Maintain
Anaerobic septic systems are simple to install because they have fewer parts than other systems. They mainly consist of a septic tank, pipes, and a drain field. This makes the setup faster and less complicated.
When it comes to maintenance, these systems are also easier to take care of. You only need to pump the septic tank every three to five years to remove solid waste buildup. As long as you avoid flushing harmful materials (like grease, chemicals, and wipes) and take care of the drain field, the system can last for decades with minimal problems.
Anaerobic Septic System Maintenance Tips
Your septic system removes waste and water from your home. Taking care of it helps prevent costly repairs and keeps it working properly for years. Follow these simple tips to avoid problems:
1. Watch What Goes In
Avoid flushing chemicals, paper towels, baby wipes, and hygiene products. These items can clog your system and cause backups. Only septic-safe toilet paper and human waste should go down the toilet. In the kitchen, avoid pouring grease, oil, or food scraps down the drain, as they can build up and block the system.
2. Pump the Tank
Every three to five years, hire a professional to pump your septic tank. This removes solid waste that collects over time and prevents clogs, leaks, and drain field issues. If you have a large household, you may need to pump the tank more often. Pumping usually costs around $400, but it can save you from expensive repairs later.
3. Protect the Drain Field
The drain field helps filter and absorb wastewater, so keeping it clear is important. Do not park cars, build structures, or plant trees over the drain field, as these can damage the system. Also, direct rainwater and downspouts away to prevent too much water from soaking into the field, which can cause flooding and slow drainage.
4. Use Water Wisely
Too much water at once can overload your septic system and cause backups. Spread out laundry loads, fix leaks, and use water-efficient toilets and faucets to reduce strain on the system.
5. Call a Professional When Needed
Schedule a septic inspection every few years to catch small problems before they become big issues. If you notice slow drains, bad smells, standing water in the yard, or gurgling sounds in your pipes, contact a septic professional right away. Ignoring these signs can lead to serious damage and costly repairs.
Taking care of your septic system keeps it working properly and helps avoid expensive problems in the future.
Take Care of Your Septic System Before Problems Start
An anaerobic septic system is a reliable and cost-effective way to manage wastewater, but it only works well if you take care of it. Many homeowners don’t think about their septic system until a problem arises, but waiting too long can lead to expensive repairs and messy backups.
Following simple maintenance steps, such as pumping the tank regularly, using water wisely, and avoiding harmful chemicals, you can extend the life of your system and prevent major issues. Small habits, like being mindful of what goes down your drains, make a big difference over time.

FAQs
How to maintain an anaerobic septic system?
To maintain an anaerobic septic system, pump the tank every three to five years to prevent waste buildup. Avoid flushing grease, chemicals, wipes, or other non-degradable items that can clog the system. Use less water by fixing leaks and spreading out laundry loads to prevent overloading the tank.
How long does an anaerobic septic system last?
An anaerobic septic system lasts 15 to 20 years, but with proper care, it can last 30 years or more. To extend its lifespan, schedule professional inspections every two to five years, limit wastewater use, and avoid flushing grease, chemicals, and wipes. Regular pumping also helps keep the system working well.
How long can you maintain anaerobic?
An anaerobic system works during the first few seconds of exercise and lasts for about up to 2 minutes. After that, as the exercise continues, the body needs more energy. This is when the aerobic system takes over, providing energy for longer periods.
What Can Damage a Septic Tank?
Avoid pouring bleach, ammonia, pesticides, or paint thinners down the drain—they kill helpful bacteria. Flush only toilet paper and human waste to prevent clogs. Keeping these out will help your septic tank last longer and reduce potential maintenance expenses, which is especially important when considering anaerobic septic system cost.
