The Septic tank is responsible for disposing of your house’s wastewater outside the property. Several factors are there that determine the average septic tank capacity. State, county, and city regulations may require authorized tank sizes, material, and location. Alongside, the soil type plays a significant role in the system’s effectiveness, impacting the septic tank and drain field size. The size of a septic tank depends on whether it’s designed for residential or commercial usage.

When it comes to septic tank type, plastic septic tanks are excellent choices for modern septic tanks. Moreover, plastic septic tanks are more crack resistant than other concrete tanks.

The septic system type:

Typically, seven types of septic systems are there, which affects the tank size you plan to use. Common types of septic tanks are outlined below:

  • The conventional, gravity-fed, anaerobic system

  • Above-ground septic system

  • Pressure system

  • Aerobic system

  • Mound system

  • Recirculating sand or gravel filter system

  • The bottomless sand filter system

However, the conventional, anaerobic system is the most prevalent one that most people envision when they think of a septic tank. Since these tanks are big, they require heavy and expensive equipment to install. On the contrary, plastic and fiberglass septic tanks are lighter and suitable for hard-to-reach and remote areas.

Local government regulations:

Local government rules for septic tanks vary widely across the country. It can be due to different soil geographies and water availability that vary by state. Hence it’s imperative to visit the local area construction department for regulations and codes for private wastewater management before purchasing a septic tank.

Wastewater usage:

The average volume of wastewater produced for the septic tank to handle determines what septic tank size is needed. Most government recommendations for the smallest tank capacity in residential usage are based on the number of bedrooms in the house. As a starting point, the recommendation for household use is a 1000-gallon septic tank, which can be suitable for a two or three-bedroom home. A four-bedroom house requires 1200 gallons septic tank and a 1500 gallons septic tank for a five to six-bedroom house. To ensure your septic tank’s efficient working, get a septic tank inspection from the professionals to determine how often you need septic pumping in Roseville for your house.

Soil type:

The underground soil type contributes significantly to system effectiveness and tank size. It’s linked to the recommendations and regulations of the specified authority, usually, the department of health, that regulates septic tank installations. To determine whether the ground is appropriate for a septic tank system, a trained specialist will visit the location to undertake various tests.

A soil percolation evaluation, often known as the perc test, is the most prevalent one. This test will evaluate if the subterranean soil may handle and filter septic tank effluent. If you are installing a septic tank on your own, you must contact your local oversight department to have perc tests or ground area evaluations performed.

The exact septic tank size you require depends on the considerations discussed in this article. There’s no one-size-fits-all answer to this question. A significant amount of variation is there, depending on where you reside. Consider contacting specialists to help you make an informed decision about the perfect tank size for your house.
