Choosing the Right Septic Tank Size for Your Home

Are you adding a new septic tank or replacing an old tank for your home? Getting the right size tank for your needs is crucial for low septic maintenance. A tank that is too small for your family and home size will need more frequent pumping and may become overloaded. Before choosing the size of your septic tank, keep these tips in mind.

  • How many bedrooms you have. Specifications for septic systems are usually based on how many bedrooms a home contains. For example, many jurisdictions will require a tank of at least 1,000 gallons, with larger required for homes with three or more bedrooms.
  • People living in the home. It is not just the size of the home that matters; it is also the size of the family. If you have a growing family, you need to plan ahead for the size of family you may have in the future, not the size it is now.
  • Large events. Do you plan to host large events at your home? If you do, you will want to consider a larger septic tank than your home normally would normally need. A holiday gathering over a weekend with twenty people at your home could easily overload a smaller septic system.
  • Replacing an existing tank. If you are replacing an existing tank, don’t automatically choose the same size. It may be time to upgrade to a larger tank for your increased septic needs.

In general, it is usually better to go bigger than smaller when it comes to choosing your septic tank. Consult with your local septic company to determine the best size tank to meet your family’s needs now and in the future.

What Are Septic Tanks Made Of?

Even for homeowners whose households rely upon a septic system for waste water disposal, the system can be something of a mystery. Knowing more about your septic system is key to maintaining it properly, though. In the interest of better understanding your septic system, finding out what it’s comprised of and how it’s made is a smart move.

There are three primary materials used in the construction of septic tanks. Just as there is no one-size-fits-all solution for septic tank sizing, different materials come with their own benefits and drawbacks.

Some septic tanks are made of steel. These tanks can degrade over time, and come with no guarantee regarding the life of the tank itself. Wastewater, acids and salts can deteriorate a steel tank, weakening its structural integrity.

Pre-cast concrete septic tanks can actually strengthen over time, and are thought to be less likely to collapse during septic tank pumping. The concrete is more flexible that steel or fiberglass, and can even be watertight when they’re manufactured according to NPCA best practices. Still, they may also be subject to deterioration from salts, acids and wastewater.

Many new septic tanks are made of high-tech polymers and high-density polyethylene. These are not as prone to degradation due to normal use and exposure to waste. Most come with long factory guarantees, which is not the case with steel and some concrete tanks.

If you’re installing a septic system on a new construction site or replacing your existing tank, it’s important to discuss your questions with an experienced sewer and septic professional. They can address these questions and help you to choose a septic tank of the right material for the conditions on your unique property.
