Understanding septic systems probably isn’t on the top of your list of things to learn about this year.  But, when you are buying or building a home in Locust Grove, having some basic knowledge about these systems may come in handy if you find yourself looking at a home with one.

What is a septic system?

A septic system is a method for managing the waste water a home produces when it is not connected to a public sewer system.  They are common in rural areas.  Septic systems do require routine maintenance.

A perc study completed by an AOSE professional will help determine the size, location, and type of system needed for a specific piece of property when you are buying land for a home in Locust Grove or elsewhere.

Depending on the type of soil on a piece of property, the technician will suggest either a conventional or alternative system system.

What is a conventional septic system?

This system is made up of two main parts-a septic tank and a drainfield.  All of the waste water in a home exits through a main drain into a septic tank.  This tank, buried in the ground, allows the water to separate from the solid material.  The waste water then travels through pipes that have holes in them into the drain field where it naturally seeps and is filtered through the soil eventually returning to underground water. Meanwhile, the solids are removed by a professional company every three to five years.

Is there anything I should avoid doing if I have a conventional septic system?

There are some things that you can do to help maintain the system.  First, don’t put food scraps, prescription drugs, cooking grease, or other household chemicals down the drain as a way to dispose of something.  Don’t plant trees near the drainfield because the roots can break the pipes under ground.  Don’t drive or park cars on the drainfield.  The weight of the vehicles can compact the soil and crush the pipes.

Is it harder to sell a home with a conventional septic system?

Most buyers who are searching for a home in a rural setting expect to find septic systems, so it is not harder to sell a home with one.  However, depending on the specific regulations where you live, the system will undergo an inspection as part of the home selling process.  Likewise, most areas have a regulation about pumping the system prior to selling or within a certain time frame.

What is an alternative septic system?

If a piece of land does not meet the criteria for an installation of a conventional system then an alternative system needs to be considered.  This can happen for a variety of reasons such as:

  • The layer of bedrock is too close to the surface of the earth so a tank can’t be buried
  • The property is near a body of water sensitive to water pollution
  • The soil is clay which has poor drainage capabilities (hello Virginia!)
  • The water table is high

An alternative septic system isn’t just one system.  It’s an umbrella term for a group of systems.  The alternative system that works best for one piece of land may not be the best one for another. 

Because of this specificity, installing an alternative system is more expensive and usually requires more maintenance than a conventional system.  However, if a buyer has found a piece of property they really want, then considering an alternative system is a possibility.

The best way to know the specific costs and maintenance commitment to an alternative system is to talk with the technician that examined your property.
