Local septic care for Houston homes
Not every home in the Houston area is on city sewer. Properties on the edges of the metro area and in unincorporated parts of Harris County often rely on aerobic or conventional septic systems. South Texas Environmental serves Houston-area homeowners, including Crosby, from our base in Waller.
We are a family-owned business established in 1991. You get licensed technicians, plain-language recommendations, and service focused on preventing costly failures rather than upselling.

What happens when you call
Tell us what you are noticing: an alarm, an odor, slow drains, wet ground, or simply that it has been a while since anyone looked at the system. We will ask a few questions about the type of system you have and when it was last serviced, then schedule the right visit. On site, we look at the system, explain what we find in plain language, and tell you what needs attention now and what can wait.
Questions Houston homeowners ask
Do you work on aerobic and conventional systems in Houston? Yes. We provide inspections, maintenance, and repair support for both.

How much does service cost? It depends on your system and what it needs. Contact us for current pricing and availability in your area.
Simple habits that protect your system
Pump the tank every 3 to 5 years for most households, keep the chlorinator stocked if you have an aerobic unit, spread out laundry loads, and keep wipes, grease, and chemicals out of the drains. Our septic do's and don'ts and septic FAQs pages cover more.
