Existing System Evaluations

Existing system evaluations are typically preformed as a part of a real estate transaction in order to determine the adequacy of the water supply and/or the sewage disposal system for an existing home.  These evaluations may be requested by a seller, potential buyer (or by lending institution), or they may be required by the local building authority as part of the building permit process.

Existing system evaluations are conducted by a health department sanitarian who evaluates these systems in accordance with the current local sanitary code to determine whether the system meets “substantial compliance” requirements.  On-site sewage disposal systems are evaluated according to size requirements, structural integrity, proper isolation distances, and evidence of malfunction/failure.  Water supply systems are evaluated for isolation distances, construction deficiencies, and water quality.

Applicants must be aware of site preparation requirements for sewage disposal systems and in the case of a water supply evaluation, must be present to allow the sanitarian in the home to collect water samples and evaluate all water supply equipment located inside. See link to the right for the Evaluation Procedures.
