Additional Observations
Statement of Condition
The sewage disposal system did not pass all the criteria for this inspection. The system is in need of further evaluation and/or repairs by a qualified/certified/licensed septic contractor or by an officer of the local jurisdictional authority.
No visible indication of any malfunctions seemed present upon visual inspection. Functional drain flow was observed inside the structure at various fixtures. System drainage was not stopped and there was no effluent breakout at the surface in the maintained area of the yard, in the reported septic area. We did not detect odors nor see effluent in the maintained area of the yard. It is still possible that the septic system is in need maintenance or service, as key system components are buried.
The inspector is unable to verify if the system is functioning properly at this time, further investigation and/or return visits at a later date are necessary. There was not insufficient information or accessibility available to make an evaluation.
