txnevels,
Call the local on-site sewage treatment system regulatory agency in your area. If the original owners obtained a permit for the system, the permit will describe the type of system originally proposed, and if the inspector signed the final inspection line on the permit, then there is a good chance that system was installed as originally proposed.
To determine the suitability of the system to adequately treat the expected sewage flow, contact a local septic system service company and request an inspection of the system, and a report of the system condition.
