Private wells: your owner checklist

Confirm water source and records

Start by confirming if the property uses City of Boerne water, a water district, or a private well. If it is a private well, you are responsible for testing, maintenance, and compliance. Ask for any driller’s reports, pump service records, and prior lab results. Keep digital copies for future sales and refinancing.

Registration, permits, and licensed pros

Before drilling a new well or changing an existing one, contact Cow Creek GCD to determine registration and permitting needs. Always use a licensed driller and pump installer, and ask for proof of licensure and insurance. This protects you and helps ensure your well report is filed correctly.

Water testing and wellhead protection

Plan to test at least once a year for total coliform or E. coli and nitrate. Test after maintenance, after flooding, or if taste, odor, or color changes. The Texas Well Owner Network explains what to test and how to find certified labs. Texas Well Owner Network FAQ

Drought and pumping limits

Groundwater in the Hill Country can be sensitive to drought. Cow Creek GCD may set conservation measures that affect irrigation or nonessential use. If water quantity is a concern, consider a yield or pump test during your option period and review current district guidance. Cow Creek GCD drought and conservation context

Septic systems: your owner checklist

Permits, timing, and who to call

In unincorporated Kendall County, septic permitting runs through the County. The County reviews complete onsite sewage applications within a set timeline, so plan ahead for site evaluations and inspections. Inside city limits, check City of Boerne requirements first.

System type, maintenance, and paperwork

Conventional systems use a tank and drainfield. Aerobic systems add treatment and require ongoing maintenance, reporting, and in Kendall County a recorded affidavit that alerts future owners. Keep your maintenance contract and service logs in one place and update them after each visit.
According to state guidance, conventional systems often need pumping about every 3 to 5 years based on use and conditions. Aerobic units require more frequent inspections and reporting. TCEQ OSSF maintenance guidance

Inspections during a sale

Most septic inspections happen during the buyer’s option period. Lenders may have specific requirements, so verify early and agree in writing on who pays to uncover lids or pump the tank if needed. Make sure buyers receive system documents, permits, and recent service reports.

Red flags and when to bring in a pro

Watch for sewage odors, slow drains, standing water over the drainfield, or unusually lush growth over the field. These can indicate a problem with the system. A licensed site evaluator or septic contractor can assess issues and recommend repairs. Septic systems basics and signs of failure
