Learn the True Cost of Septic Systems

Rural living has become a very appealing option recently. Many Americans are leaving cities in response to the ongoing pandemic. In a 2020 survey, almost half of U.S. adults said they would prefer to live in a small town or rural area.

If you live in a rural area, you know the many benefits it offers. What many don’t realize is that the rural lifestyle has its challenges as well. One of these challenges is waste treatment.

If you are planning to move to the country, you need to consider the cost of septic systems. Septic systems are underground chambers that filter sewage and wastewater.

City homes are connected to municipal sewer lines. But the cost of connecting a new home in a rural area to the city sewers is extremely costly. Installing your own septic system is much more affordable and better for the environment.

There are many different types of septic systems and cost associated with their installation and repair. In this guide we will break down the costs of each type of septic system.

Total Cost of Septic Systems

Many different factors come into play when deciding on the right septic system for your home. You will need to consider the size of your home as well as the type of soil your home sits on. Groundwater table height is also very important.

In addition, the costs, requirements, and permitting for septic systems vary from state to state. Before you get started installing a septic system on your property, check the rules for your area.

The average cost to install a new septic system is around $6,000. However, high-end septic systems can cost more than twice that amount.

The size of your home is the most important aspect to consider when selecting a septic tank. You will need a tank that can hold both the amount of waste produced in the home, as well as the water used to filter it.

A two-bedroom house requires at the very least a 750-gallon septic tank, but some areas require a 1,000 gallons. A three-bedroom home requires at least a 1,000 gallon tank. Finally, a four-bedroom home requires a 1,250 gallon tank.

Types of Septic Systems

When it comes to septic tank installation, the total cost is going to depend heavily on the type of system you choose. You will also need to consider the cost of labor and materials.

There are several different types of septic systems to select from, with costs ranging from $500 to $20,000.

Conventional Septic System

Conventional septic systems require a large amount of space. This type of system contains a septic tank and a trench. The trench works in a similar way as a drain field.

Conventional trenches typically consist of stone or gravel with a layer of geotextile material on top. The combination of gravel and permeable fabric allows water to pass through the trench without contaminating clean soil.

The benefit of this type of system is that the simple design doesn’t require any type of pump that could get clogged. Conventional septic systems are an excellent choice if you are looking for something affordable and familiar.

Conventional septic tank systems typically cost between $2,000 and $5,000.

Chamber Septic System

A chamber septic system is similar to a conventional system. But, where a conventional system uses gravel to filter waste, a chamber septic system uses plastic chambers.

Chamber septic systems have become a common choice for homeowners looking for systems that are simple to construct and have less of a carbon footprint than conventional systems.

Chamber septic tank systems cost between $1,500 and $5,000.

Anaerobic Systems

An anaerobic septic system uses a natural recycling process involving bacteria to break down waste. The bacteria doesn’t need oxygen to survive, hence the name anaerobic.

The bacteria breaks down the solid waste. Then the leftover liquid waste moves through pipes that allow the liquid to pass underneath the soil.

Anaerobic systems are a great choice if you want to avoid septic systems that require additional energy sources and harmful chemicals. These systems typically cost between $2,000 and $5,000.

Aerobic Systems

Aerobic septic systems are similar to anaerobic systems. The difference is that aerobic systems utilize bacteria that require oxygen to survive. That’s why aerobic systems use pumps to release oxygen into the septic tank.

Aerobic systems are a good choice for homes situated on unfavorable soil or near bodies of water where the groundwater table is too high for other types of septic systems.

Aerobic systems are on the pricier end, costing between $10,000 and $20,000.

Mound Septic Systems

Another great option for homes where the groundwater table is near the surface of the soil is a mound septic system.

These septic systems require a large amount of space. In order for them to keep waste from contaminating the groundwater, they contain a septic system with an expansive mound of sand under and around it.

To operate, the system pumps small amounts of wastewater into the mound. The gradual pumping process allows the sand to filter the water before it enters the soil and groundwater.

Mound septic systems are also quite costly. They run between $10,000 and $20,000.

Gravity Septic System

Gravity septic systems use gravity to filter wastewater. The system consists of a series of pipes that carry waste from the home to the septic tank. Inside the tank, sewage and wastewater separate into three distinct layers.

In order for a gravity septic system to work without a pump, your home must be situated near a gentle slope. Gravity septic tanks cost between $1,500 and $4,000.

Cost to Repair Septic Systems

If you clean and maintain your septic tank properly, it should last an average of 20 to 40 years. However, all mechanical systems require repairs from time to time.

Fortunately, repairing a septic system is far less costly than installing a new system. Some of the most common septic system repairs include drain fields, tank lids, pumps, baffles, and filters.

Drain Field

When a septic drain field gets overloaded and floods, it can cause sewage to back up into your home’s plumbing fixtures. To repair a drain or a leach field, it will cost between $3,500 and $11,000.

Tank Lid

Typically, septic tank lids are made out of concrete and steel. Over time, concrete can crack and steel rusts. Replacing a septic tank lid yourself requires a very minimal cost of $35 to $60, while professional replacement costs more.

Tank Pump

A broken pump can render most septic tanks unusable. Replacing a septic tank pump can cost between $500 and $1,200.

Tank Baffle

The tank baffle is what directs the flow of wastewater through the septic tank. Replacing a baffle is pretty inexpensive, running between $20 to $50.

Tank Filter

Tank filters enable the septic system to filter wastewater and sewage. They are the most common septic tank repairs and replacements. Replacing a tank filter can cost between $230 and $280.

Septic System Installation

It is important to choose the appropriate type of septic tank for the property your home sits on. The total cost of septic systems includes the type of septic system, the size of the home/tank, materials, and installation.
