When you are building a new home, one of the last things you probably think about is your septic system. After all, it’s not as much fun to shop for tanks as it is cabinets, appliances, and floor coverings. Yet, even though you’ll never show it off proudly, your guests WILL know if you don’t have the right septic tank installed.

Septic Tanks for New Home Construction

The correct size of the septic tank depends mostly on the square footage of the house and the number of people living there. Most residential septic tanks range in size from 750 gallons to 1,250 gallons.  An average 3-bedroom home, less than 2500 square feet will probably require a 1000 gallon tank.  Of course, all of this depends on the number of people living in the home and the amount of water and waste that will be put into the system.

A properly sized septic tank should hold waste for 3-years before needing to be pumped and cleaned.

The best way to determine the correct size of septic tank for your home is to contact a reliable septic company. They can help you plan the specifics of your septic system, including which type of septic system will serve you best

Planning Your Drain Field

  • Do not allow vehicles on or around the drain field.
  • Do not plant trees or anything else with deep roots near the bed of the drain field. The roots often clog the pipes.
  • Don’t drain downspouts or sump pumps into the septic system.
  • Do not tamper with or alter with natural drainage features without researching and considering how it will affect the drain field.
  • Do not build additions over the drain field or cover it with concrete, asphalt, etc.
  • Make your septic tank cover as accessible as possible. This allows for easy maintenance and inspection.
  • Keep the area grassed to assist with evaporation and prevent erosion.

A Home Addition May Mean a New Septic Tank

Do not significantly add to or renovate your home or business without having the size of your septic system evaluated. If you are planning on installing a home addition that is bigger than 10% of your floor area, increases the number of rooms, or requires additional plumbing installation, you will probably need to enlarge your septic tank.

  • If you are planning on a home addition that requires a building permit for more use of your septic system, your local health department will require a signed and authorized letter confirming that the new septic system is capable of accommodating the increase in wastewater.
  • Do not attempt to replace your septic system without the help of a licensed and qualified professional.
