Montgomery County is one of the fastest-growing regions in Texas—and with growth comes stricter septic regulations. Many properties in areas like MagnoliaHigh Meadow, and surrounding rural areas are required to install aerobic septic systems, especially in areas with clay-heavy soil or smaller lots.

If you’re moving into a new home, upgrading an aging system, or needing repair for failing equipment, aerobic septic systems offer many advantages:

  • Cleaner, higher-quality effluent
  • Works where soil fails traditional systems
  • Long lifespans with proper maintenance
  • Stronger environmental protection
  • System control panels and alarms for safety
  • Works on small lots and challenging terrain
  • Easy access to components for long-term service

Unlike older anaerobic systems that struggle with Montgomery County’s clay soils, aerobic treatment units (ATUs) use oxygen to break down waste rapidly and efficiently. For many of Montgomery County’s rural neighborhoods, aerobic systems (if not required) are strongly recommended for proper waste management.

If your septic alarm is going off, your septic aerator isn’t working, your spray heads aren’t popping up, or water is pooling near the spray field, we can diagnose the issue quickly and provide the right repair.

Considering upgrading to a safer, more efficient aerobic septic system? Call 1 Source at 936-297-8991.

Your water well system is one of the most important components of your property—whether you’re supplying water to your home, acreage, ranch, or commercial building. When you rely on your own well, you need a system that delivers safe, clean, reliable water every single day, without the frustrating water pressure drops, pump failures, or water quality issues.

Living in Montgomery County means dealing with diverse and sometimes challenging soil conditions: dense clay pockets, sandy loam throughout Montgomery and Stagecoach, and deeper, more variable substrate toward Lake Conroe and northern rural areas. These geological differences determine how deep a well must be drilled, how your pump must be configured, and what filtration or treatment systems you may need.

When you choose 1 Source, you get a team equipped with advanced drilling rigs, up-to-date TCEQ knowledge, and years of experience working exclusively with Texas groundwater systems. We handle residential wells, irrigation wells, commercial wells, agricultural wells, and complete conversions from municipal water to private wells.

Every system is designed around your property’s depth requirements, soil profile, expected usage, and long-term reliability goals. To help you make informed decisions, we perform a full on-site assessment, analyze groundwater behavior, and review your existing infrastructure before recommending a solution.

If your well water has changed color, smells unusual, lost pressure, or your pump keeps cycling, our team will inspect the full system and identify the exact cause—whether it’s the pressure switch, pump motor, tank failure, or bacteria buildup.

They walked us through every step, answered all our questions, and delivered a system that works flawlessly. It’s clear they take pride in their craftsmanship and truly care about their customers.

I can always count on 1Source to give exceptional service. I called about installing risers, and they were incredibly prompt in getting everything scheduled and completed. The whole process was smooth, efficient, and stress-free.

As always, their service was wonderful—fast, reliable, and done right the first time. It’s such a relief knowing I can count on them whenever I need help. Highly recommend!

One Source has gained our business for life! Their office was always available for questions and assistance coordinating with our other contractors (especially regarding getting permits and all that fun stuff). Their quote for our 3 bed 2 bath house and barn bathroom was very spot on so no surprises on that front. They are super friendly and personable people. Joey the owner personally talked with us to ensure the tanks went in the best spot and made the install seamless. The install was done within 2 days and they backfilled everything well and our yard was back to normal pretty quick! They have great customer service and take pride in what they do and it shows. Recommending to all our friends and family !

Very happy with the Well job and looking forward to the septic install.

I had an issue with my water well yesterday & called "1 Source Water Well & Septic Service." I spoke to Jessie & she was so very nice & super helpful. She had one of her service gentleman, Paul, call me & he knew exactly what the problem was & even explained to me, what I could do, for a temporary repair until he got here early this morning. He showed up promptly and knew exactly what it was. He repaired and fixed the problem with no issues. It is so wonderful & really refreshing to find a great company like, "1 Source Water Well & Septic Service", that is so professional, down to earth, truly friendly, so very nice & affordable.

They answered all my questions and had a solution to my problem. Excellent customer service
These guys came right out. I observed great teamwork from the 3 techs and very professional... they pulled my broken 2hp pump and replaced it, the pressure switch and pointed out where my pump got shorter out!

You are very reasonably priced. I normally use another company...the one that drilled the well...they just lost a customer and you guys have a new loyal customer!

I would give Joey and his crew 10 stars if I could. They were awesome !!! Very professional and answer all of my questions. If you need septic or water well services, 1Source Water Well & Septic is the company you need to call. I have dealt with multiple contractors and maintenance companies in the past, none of them compare to 1Source ! For the system they installed and the work that was done, they stuck to the price that I was quoted. Of the seven quotes that I received, 1Source was the third lowest. Point being, I did my homework before I chose 1Source.
Response from the owner:Thank you for your positive feedback, Mr. LarGe! You, too, were great to work with. Please let us know if you ever need anything in the future and we will be happy to help.
