Common Septic System Types

Posted on


Many years ago there was only one type of septic system, consisting of a septic tank and drainfield. This type of system is now referred to as a standard or conventional system, with all the system types called “On Site Sewage Facilities” or “OSSF.” Most people, though, refer to them simply as “septic systems.”

More knowledge, better systems

As we’ve learned more about how soil structure treats wastewater, the septic system industry has improved. The technology of septic systems has evolved in order to meet the need of treating wastewater — today’s systems perform much more effectively, meaning our groundwater resources are more protected.

Since the wastewater in a conventional/standard septic system is treated in the soil beneath the drainfield, the soil structure affects how well the wastewater is treated. Because we obtain our drinking supply from groundwater, it’s important that the wastewater is treated by the soil before it enters the groundwater supply.

Common system types

Today, there are many types of OSSFs. In San Antonio and the surrounding areas, the most common types of OSSFs are:

The latter systems are more complicated and need more maintenance than a conventional/standard septic system, but may be necessary in order to treat wastewater properly. The type of system installed on a property depends on the properties of the soil and regulations set by the Texas Commission on Environmental Quality (TCEQ).

Each type of OSSF is different in the way it works and the type and amount of maintenance involved. Stay tuned to learn more about the most common system types, and what you can do to keep your system functioning and treating your wastewater to the best of its ability!
