Frequently Asked Questions

  • The typical process includes:

    • Site evaluation

    • Soil analysis

    • System design

    • Preparation of plans

    • Submittal to the county for permitting

    We handle this entire process for you.

  • If your property is not connected to public sewer, you will need an On-Site Sewage Facility (OSSF), commonly known as a septic system. We can help determine this during an initial consultation.

  • Our septic system design fees typically start at $850, depending on the property and project complexity. Final pricing may vary based on factors such as site conditions, location, and system type. We’re happy to review your property and provide a more specific estimate.

  • The cost to install a septic system can vary depending on the type of system, soil conditions, and layout of the property.

    In general, most residential systems in this area are typically $10,000 or more, with many projects falling in the range of $10,000 – $20,000, and sometimes higher depending on site conditions and system requirements.

    Final pricing is determined by a licensed installer after the system has been designed and permitted.

    As a septic system designer, my role is to evaluate your property, design the appropriate system, and guide you through the permitting process. Once the design is complete, I can help connect you with qualified installers who can provide bids.

  • The type of system depends on soil conditions, available space, and site constraints. Common systems include:

    • Aerobic spray systems

    • Aerobic drip systems

    • Conventional systems

    We design the most appropriate system based on your property.

  • In Texas, aerobic treatment units (ATUs) are typically required to have a maintenance contract with a licensed provider for the first two years after installation. This helps ensure the system is operating properly during the initial period.

    After the first two years, some homeowners may be allowed to perform their own maintenance—but only if they complete the required training course and pass the certification test.

    However, requirements can vary by county, and not all jurisdictions allow homeowner maintenance. In addition, commercial systems generally require ongoing maintenance by a licensed provider and do not allow owner maintenance.

    For these reasons, it’s always best to check with your local permitting authority to confirm what is allowed for your specific property.

  • Design timelines vary depending on the project and can be discussed during the initial consultation. Once submitted, county review times typically range from a few weeks to a few months, depending on the jurisdiction and complexity of the project.

  • Yes. We prepare and submit the design and supporting documents to the county and coordinate as needed during review.

  • We specialize in design and permitting only, but we can recommend qualified installers in your area.

  • Septic system (OSSF) rules in Texas come from a combination of state regulations and local county requirements.

    At the state level, the Texas Commission on Environmental Quality (TCEQ) establishes the minimum standards for septic system design, permitting, and installation under Title 30 of the Texas Administrative Code, Chapter 285.

    Local counties and municipalities then administer these rules through their own OSSF orders or ordinances, which are approved by TCEQ. In some cases, counties may adopt more stringent requirements based on local conditions such as soil types, density, or environmental concerns.

    As a result, septic system requirements can vary slightly from county to county, even though they are all based on the same state framework.

  • Do:

    • Use water efficiently. Spread out laundry and avoid heavy water use in a short period of time to prevent overloading the system.

    • Fix leaks promptly. Dripping faucets or running toilets can overload your system over time.

    • Pump your tank regularly. Have your system inspected and pumped by a licensed provider as recommended.

    • Maintain proper drainage. Keep surface water away from the drainfield to prevent flooding.

    • Maintain grass cover. Grass helps prevent erosion and promotes proper evaporation in drainfield and spray areas.

    • Keep system areas accessible. Make sure tanks, cleanouts, and components are easy to locate and service.

    Don’t:

    • Don’t treat your septic like a trash can. Only flush toilet paper and wastewater.

    • Don’t pour grease or harsh chemicals down the drain. This includes oils, paints, solvents, and excessive cleaners.

    • Don’t flush non-biodegradable items. Wipes (even “flushable”), diapers, feminine products, paper towels, etc.

    • Don’t build over your system. Structures can damage components and prevent proper maintenance.

    • Don’t drive or park on the system. Heavy equipment can crush pipes and tanks.

    • Don’t overwater the area. Excess irrigation can flood the drainfield or spray area.
