Many factors can influence how much a new septic system can cost. Whether you’re building a new property or want to replace your current septic tank system, there are some things to keep in mind.
If you’re looking to install a septic system, keep reading for an overview of its costs.
What Is a Septic System?
In simple words, a septic system is an underground treatment structure created when there’s not a traditional sewer system available; these systems are more common in rural areas, although they may also be seen in some cities.
A conventional septic system has three primary parts: The tank system, the distribution box, and a leach field, which is responsible for absorbing soil. In essence, the septic tank systems’ job is to separate wastewater from organic matter, such as solids, grease, or oil.
How Much Does a Septic Tank System Cost?
On average, installing new tanks on your property may range from $3,000 and $10,000, depending on several factors. The national average for septic system installation costs is approximately $6,000.
Here is a list of the most common factors that affect the cost of a new septic tank system:
Bedroom Count/House Size: This is the most important factor that affects septic system costs. On average, a three-bedroom house needs a 1,000-gallon tank; this tank may range from $600 to $1,000. Larger homes would need more than 1,500-gallon tanks.
Tank Gallon Size: The bigger the tank, the higher the cost. Keep in mind that 3,000-gallon tanks or bigger can accommodate most small buildings, and these may range from $3,000 to $4,000.
General System Type: There are three primary system types: Mound septic system, sand filter system, and pressure distribution system. Mound systems are the most expensive to install at $15,000 on average, whereas the sand filter systems are a bit more affordable, ranging from $6,000 to $10,000.
Septic Tank Type: In this case, we have concrete septic tanks, fiberglass tanks, steel tanks, and plastic tanks. The concrete septic tank is the most durable and expensive. On the other hand, plastic septic tanks are much more affordable than concrete tanks, but they’re not as durable.
Septic Tank System Type: You can choose from conventional, alternative, and engineered septic systems. Conventional septic systems are the most common, and they do a great job at collecting solid waste.
Anaerobic or Aerobic Systems: The aerobic septic system uses an air pump to aerate the tank, allowing bacteria to take care of the waste. On the other hand, the anaerobic septic system uses oxygen-averse bacteria to take care of the waste. The aerobic and anaerobic system are good; it mostly depends on your budget.
