Conventional Septic System Components

We Specialize in Conventional Septic Systems

Also known as lateral lines and leech lines, conventional septic systems are often less expensive and more efficient than an aerobic septic system but only with absorbent soil, which will be determined by an Oklahoma DEQ soil test. If you need help finding a certified soil tester in your area, contact us, we can recommend one for you. A soil test will be required for all lateral line installations and costs around $300.

NOTE: Septic installers are NOT soil testers. 80% of the conventional systems we install have been told by another company that their properties wouldn’t pass a soil test and an aerobic system was their only option. 

This type of system should be installed in a large open area with no trees, gentle slopes, good drainage and no vehicle traffic.

In most cases, we can install a lateral line septic system in one day. Depending on the DEQ requirements for your septic system, it could take two days to complete.

While it will be next to impossible to make your yard look like we haven’t been there at all, we spend extra time after the installation dressing up your yard as best as we can. There is no extra charge for final dirt work.

Septic System Pricing

Pricing for conventional septic system installations is 100% dependent on a soil test. We get asked daily for a ballpark price and there’s just no good ballpark number for this type of system. But most of the time, we can keep it between $4,000-$8,000, sometimes less depending on the system size.

If the soil tester determines you need a high footage of lateral lines, conventional septic systems will cost you more at the time of installation, but still less than an aerobic system in the long run.

Small deposit

We do require a small deposit for septic system installations. The remaining balance is due in full at the time of service. We accept cash, checks and credit cards. However, keep in mind, there is a 4% convenience fee added when paying by credit or debit card.

Highly recomended

Our happy customers leave glowing reviews on Google and Facebook.


A properly installed conventional septic system will typically last anywhere from 20-40 years if you properly maintain it.

Septic System Maintenance

Conventional septic systems are low maintenance and that’s why we prefer them. You will need to have your septic tank pumped every 3-5 years, depending on how many people live with you. If you don’t know a septic pumper in your area, contact us and we can refer you to one.

Sometimes an aerobic system is your only option, but if DEQ will allow for a conventional septic system, we highly recommend it.

Septic System Failure

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.
