Can Septic Tank Be Under Driveway? This is a question that many homeowners have asked themselves in their lifetime. Unfortunately, the answer to this question is not simple and straightforward. In order to answer this question, the best place to start is by defining what a septic tank is.

A septic tank is used to contain and treat wastewater from a building before it is discharged into the environment. It collects all of the household waste from toilets, sinks, showers, and other sources and treats it with bacteria that breaks down the waste.
The wastewater then percolates through soil and rock layers to a nearby leach field or drain field.

Can Septic Tank Be Under Driveway? The answer is yes or no. Let’s start with the downsides of having a septic tank or septic mound system under the driveway:

  • The weight of driveway pavement and cars will compress the soil under the driveway, thus reducing the ability of wastewater to percolate through to the leaching field.
  • Also note that the septic system contains pipes, and these can be easily damaged by the weight of cars.
  • Wastewater in the leach field evaporates through the soil above it, now if you have a paved driveway over the septic tank, you interfere with that process.
  • Another con of putting a septic under a driveway, is that you would need to dig up the driveway in order to access the septic when you want to pump or fix the septic tank.
  • The rural town authorities would not easily approve installation of a septic under a driveway because it’s a hazard.
  • Septic tanks are not reinforced concrete. The septic tank will most likely collapse or cave in because of the weight of the car.
