There is a range of systems approved and available for use today.

To properly determine the system that is right for your application as well as the cost of that system there must first be an evaluation performed.  Factors like the size of your lot, along with the soil conditions will factor into the design and cost of your system

The first phase in designing your system begins with a soil analysis.This will determine the type soil conditions that are present at your location.  (If an Aerobic system is required or is obvious, there is no need to dig test holes)  Test holes must be dug in the drain field area and the soil analysis done by the engineer. If the soil conditions meet TCEQ requirements for a Standard or Convential System then that type system can be designed and installed.  If not, then an alternative system or Aerobic system would be required.  Either system would be designed to meet or exceed the codes specified by the state and county in which you live.  The design is then submitted to the county for approval.  The county will then issue a permit to construct.

Now you would be ready to install a new system from Countryside.
