If you live in Menger Springs, your septic system is part of what makes Hill Country living possible. With shallow limestone and sensitive aquifers, a well‑cared‑for system protects your home’s value and safeguards local springs and wells. In this guide, you’ll learn the basics of care, what local rules require, how often to service different systems, and the documents buyers and sellers should gather during a sale. Let’s dive in.
Why septic care matters in Menger Springs
Menger Springs sits in the Texas Hill Country, where limestone and karst features can let contaminants travel quickly into groundwater. That makes proper siting, treatment, and maintenance essential to protect wells and creeks. The area includes many homes on individual septic systems, including aerobic units and drip systems where soils are thin or lots are smaller. Understanding your setup helps you plan the right maintenance and avoid costly issues.
For more on why karst areas require extra care, see the USGS overview of Edwards and related karst aquifers and their vulnerability to contamination. Learn about karst aquifers and why they matter here.
Know the local rules
You generally need a permit to construct, alter, repair, extend, or operate a septic system in Texas. There is a narrow 10‑acre exception, but you should confirm details with the local authority before you act. Start with the state overview of on‑site sewage facility permits from TCEQ. Review state permit basics.
Kendall County requires an Affidavit to the Public on all aerobic systems and a signed maintenance contract with a licensed provider. The original affidavit must be recorded with the Kendall County Clerk, and the County Engineer’s office maintains OSSF records. See Kendall County’s onsite sewage information.
If your property falls inside Boerne city limits, the City manages building and development permits through its online portal. Always check for any city utility or permit requirements before starting work. Visit the City of Boerne permits page.
Common system types in Menger Springs
Conventional gravity systems
These use a septic tank and an absorptive drainfield. They work where there is adequate unsaturated soil depth. Plan to inspect every 1 to 3 years and pump every 3 to 5 years depending on tank size and household water use. See EPA’s homeowner care guidance.
Aerobic treatment units and drip/spray systems
Aerobic systems provide higher‑quality effluent and are common where soil is shallow or lots are smaller. They require electricity, mechanical components, and an ongoing maintenance contract with a licensed provider. Kendall County requires recorded affidavits and maintenance contracts for aerobic systems. For statewide maintenance rules and provider reporting duties, start here: TCEQ maintenance guidance.
Engineered alternatives
Mound systems, low‑pressure dosing, soil substitution, and other engineered designs are often used on steep or rocky sites. These must be designed and installed by licensed professionals following TCEQ standards. Explore system selection by site conditions.
Maintenance you should plan for
- Inspect your system regularly. Conventional tanks are typically inspected every 1 to 3 years and pumped every 3 to 5 years. ATUs usually need at least annual professional service per your maintenance contract. EPA’s homeowner guide covers the basics.
- Conserve water. Spread out laundry loads and fix leaks to avoid overloading the drainfield.
- Be careful what you flush. Avoid grease, wipes, feminine products, chemicals, and medications.
- Protect the drainfield. Do not drive, park, or build over tanks or disposal areas. Texas rules prohibit structures over treatment and disposal components. See the Texas rule reference.
- Keep records. Save permits, as‑builts, pumping receipts, repair invoices, and maintenance reports in one place.
For aerobic and advanced systems, you are responsible for keeping a current maintenance contract with a licensed provider. Providers must perform routine inspections and submit reports to the permitting authority on a set schedule. Review TCEQ’s maintenance requirements.
Hill Country specifics to watch
- Get a licensed site evaluation if you see shallow bedrock, sinkholes, caves, or rock outcrops. These features often call for engineered designs and additional treatment. TCEQ’s system selection page explains limits and alternatives.
- Respect well setbacks. A common Texas rule of thumb is at least 50 feet from a septic tank to a water well and 100 feet from a drainfield to a water well. Local programs can require more. See well siting guidance.
- If you have a private well, consider periodic water testing for bacteria and nitrates, especially with older systems or limited maintenance history.

The Kendall County Engineer’s office can help you confirm permits, affidavits, and local requirements. For system care schedules and do‑it‑yourself basics, EPA’s homeowner materials are a helpful complement to professional service.
