I had a request from our environmental department today for a waiver of liability on a septic system. I'm told the technician may have played a little loose with the soil test and rated the property for a conventional system, which the owner then had installed. Our septic inspector failed the system at the final inspection after the installation was complete. The county commissioners voted to authorize an exception, which TCEQ has signed off on, provided that everyone execute a waiver that the county would not be held liable for anything resulting from the system, that the owner would be liable to the county for anything resulting from a failure of the system, and that the system would be replaced with an appropriate one before the property is sold or otherwise transferred. Has anyone out there done something like this before?
