Johnson Construction Company

Serving Oklahoma’s Septic System and Storm Shelter Needs Since 1977

Septic Systems

Johnson Construction offers two types of septic systems, aerobic and lateral line septic systems.

Lateral Line Septic Systems:

A lateral line septic system works by using pipe and gravel in a sandy, sunny terrain. We install ETA Septic Systems. We can also replace your old lateral lines, which can make your septic system work like new again!

Here is a picture that helps illustrate how a lateral line septic system works:
