Experts in septic system design and installation in Texas


—  Installing systems that last a Lifetime  —

Everyone realizes that the Quality of sewage from a restaurant is more to treat than that from a residence, because of the presence of FOG – fats, oils and greases. But not enough attention is given to the fact that Home Sewage can also include high FOG contents from cosmetics, bath oils, suntan lotion, etc. in addition the cooking greases and food scraps.

Medications taken by persons living in the home, bleaches and non-eaten plastics and paper can also play havoc with the septic system.

Home sewage should have no higher than 60 mg/l in total suspended solids, 20 mg/l in FOG and 300 mg/l in BOD. Exceeding any of these limits can cause serious damage and malfunction to the septic system, in addition to that causes may be from more volume of sewage than for which the system was designed for.

Aerobic Treatment units (ATU’s) must be approved by TCEQ and installed, managed, monitored and maintained in accordance with manufacturer’s recommendations. All wiring and piping must be in accordance with Ch. 285, septic system regulations, as a minimum and are inspected and approved by the county to ensure those regulations are being met by the installers.

Septic system information and resources

Paul Swoyer Septic system contractors in Central Texas handles all paperwork needed to obtain the septic permit from the county. We employ an engineer (P.E.) for your septic system design in central Texas.

To determine the type of septic system you can install, the following considerations will be taken in account:

Is there enough soil present in the drain field area? At least four feet of good soil (no rock or clay) is necessary.
Is there enough room for a drain field?
Is the ground level or is it sloped greater than 15%?
Is there sufficient drop from the house to the tank location and down to the drain field?

If a conventional septic system cannot be installed, then an aerobic septic system can be designed, which will not require test holes.


Our engineer will need specific documents to design your septic system and to obtain permits from your county government.

  • Plot plan or survey
  • Recorded warranty deed
  • Square feet of living space and number of bedrooms
  • 911 address (can be obtained from County Road Office)
  • For aerobic systems only, an affidavit to public form with signatures notarized and service agreement. Forms will be furnished by installer.
