Tips for Dallas Homeowners

Test your soil before building. North Texas clay soils require careful soil perc testing. Some lots may require alternative system designs that cost significantly more.

Watch for foundation movement effects. The same clay soils that affect home foundations can shift septic pipes. If your foundation has moved, have your septic pipes inspected.

Keep accurate records. Many DFW counties require proof of regular maintenance when selling a home with a septic system.
