We specialize in conventional septic systems (lateral line/leech line). Sometimes an aerobic system is the only option for some homeowners, but if a conventional septic system is possible, we highly recommend this type of system. Click here to find out why.

There are several other types of septic systems, but these three listed are the most common types that we install

Three Common Types of Septic Systems (On-Site Sewage):

Are you unfamiliar with the different types of septic systems? If so, you’ve come to the right place. If your home isn’t connected to a central sewer system, you likely have a septic system. A septic system is a connected system of components under the ground that use natural processes to treat wastewater onsite.

Septic system design and size varies widely due to a combination of factors – household size, soil type, site slope, lot size, proximity to sensitive waterbodies, weather conditions and even local regulations.

conventional septic system

Also known as lateral lines, leech lines or a chamber system, a conventional septic system is often less expensive and more efficient than an aerobic system but only with absorbent soil. This septic system is low-maintenance. Click the image above to learn more about conventional septic systems.

aerobic systemAlso known as a Spray Irrigation System, an aerobic system is suitable for use in almost any soil condition and does not require a large area. This type of septic system is higher maintenance but may be necessary in order to properly treat the wastewater. Click the image above to learn more about aerobic septic systems.


Lagoons are an effective waste treatment system in central and western Oklahoma and are fairly easy to maintain. Click the image above to learn more about lagoons.

Septic System Failure

Researching a home’s septic system is important. Knowing there’s a septic system at the home is a great start, but understanding which specific kind of system helps with maintenance and repairs down the road. If you aren’t sure where your septic system is located or what type of system you have, contact us and we can help!

Conventional Septic Systems

If you are experiencing septic tank drain field problems, septic tank collapse or septic water coming out of the ground, these are all signs of a failing leach field. A properly installed conventional septic system will typically last anywhere from 20-40 years as long as you follow the basic rules of septic systems.

Aerobic Septic Systems

Although this type of septic system is high maintenance, they can last a long time with regular routine maintenance. We recommend signing up for a routine maintenance program once your two year warranty is up. If you need a referral, please contact us and we can recommend someone.

How Septic Systems Work

The septic system takes in the household’s waste and deposits it into the septic tank. Septic tanks are designed to be the first stop in the wastewater treatment process. They begin the waste material breakdown process, helping to filter and sort the solid waste, scum and oils from the liquid waste (as known as effluent.) Heavy solids settle to the bottom of the tank while greases and lighter solids float to the top. The solids stay in the tank while the wastewater is discharged to the drain field for further treatment and dispersal.

Instead of relying on simply releasing the wastewater into the soil, other types of septic systems use pumps, disinfecting product, an evaporation technique, or simply rely on gravity to help funnel the wastewater through sand, or other organic product, before releasing the wastewater into the soil.
