What are the steps for getting a new septic system?
Get a Site Evaluation which complies with the requirements of your county health department or with the Texas Commission on Environmental Quality.
Apply for an OSSF Permit by submitting a Permit Application and Site Evaluation and the county fee to the county health department.
What is a septic system?
A septic system refers to treatment and subsurface application of wastewater on the same tract of land where it was generated, for instance, a single-family dwelling may have a septic system in the yard.
What is an on-site sewage facility (OSSF)?
Any approved system which treats and disposes less than 5000 gallons per day wastewater on the same tract of land where it was generated.
The Soil Substitution Absorption Field for Standard Treatment project is an example of an OSSF.
Are there different types of on-site sewage facilities?
Yes, there are several methods of treating and disposing of domestic wastewater.
The Texas Cooperative Extension has a lot of brochures on the web site. Their Waste Management section should be of interest.

Who can install my OSSF?
A licensed Installer has the training and experience to properly install your new on-site sewage facility.
In some counties, a homeowner may install an on-site sewage facility for his/her personal dwelling.
What do I do if my existing septic system doesn’t work properly?
Many different conditions can result in failure of an on-site sewage facility and it is usually most cost effective to contact a licensed plumber, Installer or Site Evaluator to attempt to identify the specific problem.
Conditions which may cause a failure in an on-site sewage facility include:
Crushed or broken pipe from house to tank or from tank to laterals.
High concentration of solids in pre-treatment tank.
Excessive biomat development in lateral lines.
Lateral lines installed with improper slope.
Lateral lines installed in unsuitable soil.
Hydraulic overloading of system (too much water inflow as from faucet leak).
Biological overload of system as may happen when two homes are connected to a single system designed for only one home or when too many people are contributing waste to system.
Air compressor failure in an aerobic system will turn the OSSF “septic” with strong, disagreeable odor.
