Warning signs
- Wet, spongy or unusually green patches over the field
- Slow drains throughout the house, gurgling, toilets needing a second flush
- Sewage odor outdoors, especially after rain or heavy water use
- Backups that clear on their own after a dry spell (the field is at capacity)
Repairable causes
- Clogged or tilted distribution box sending everything to one line
- Crushed, root-invaded or separated lateral lines
- Solids carried over from a tank that was never pumped (pump the tank, jet the lines)
- Hydraulic overload — a leaking toilet or sump discharge dumping water on the field
Not repairable: a biomat that has sealed the trench-soil interface across the whole field, or a field that was undersized for the soil from day one. That's a replacement conversation, and we'll tell you so.
What a diagnosis visit includes: tank inspection and sludge level, distribution box check, probe of the trenches for saturation, and a written finding with a repair price or a replacement estimate. In Texas, repairs that alter the system require a permit; routine maintenance does not.
All work is performed by TCEQ-licensed installers and licensed maintenance providers working under the county's on-site sewage facility program.
