Septic problems we diagnose and repair
South Texas Environmental diagnoses and repairs common septic failures on both aerobic and conventional systems. We have been doing this work for homeowners around Waller and Greater Houston since 1991, and our technicians are licensed and trained under Texas regulations.
- Aerobic system alarms that will not clear
- Air pump or aerator failures
- Chlorinator problems and low chlorine levels
- Spray heads, pumps, and discharge issues
- Backups, slow drains, and gurgling plumbing
- Sewage odors indoors or around the tank
- Soggy ground or standing water over the tank or field lines
Emergency septic service
A septic backup does not wait for a convenient time. We provide emergency septic diagnostics and repair support in Waller, Katy, and surrounding communities based on scheduling availability. Phone is the fastest way to reach us. If we miss your call, leave a voicemail with your address and the problem, and we will call you back quickly.
What to do while you wait
- Cut water use: hold off on laundry, dishwashers, and long showers
- Do not keep resetting an alarm without finding the cause
- Keep children and pets away from wet areas or open lids
- Do not pour chemicals or additives into the system to try to fix it
Clear findings before any repair
We do a thorough inspection and give you a plain-language explanation before recommending work. Some issues are urgent; others can wait. We will tell you which is which, and we do not upsell work you do not need.
Many repairs can be avoided altogether with routine care. Ask us about aerobic septic maintenance contracts, and keep your tank on a regular septic pumping schedule.
Repair now, or plan ahead?
Not every problem means a new system. A failed air pump, a worn float, or a clogged spray head can often be repaired on its own. Other symptoms, such as repeated backups or a drain field that stays saturated, need a closer look to find the real cause. Either way, you get clear findings first so you can make an informed decision and budget for the work, instead of being surprised by it later.
