Bernalillo County Septic FAQs

In New Mexico, the primary wastewater system evaluation required by the state is the Property Transfer Evaluation (PTE) when a property with an onsite septic/liquid waste system is being sold or transferred. This is mandated by NMAC 20.7.3.902.E.

What is a Property Transfer Evaluation?

A qualified evaluator must inspect and evaluate the onsite wastewater (septic) system using an NMED-approved form before ownership transfers. The evaluation is intended to determine whether the system is functioning properly, permitted, and compliant with state requirements.

What is checked during the evaluation?

Typically the evaluator will review:

• Septic tank condition
• Evidence of sewage surfacing or backups
• Drainfield condition
• System location and setbacks
• Whether the system appears adequately sized
• Permit status and documentation
• Signs of system failure or health hazards
• GPS coordinates of the treatment unit for reporting purposes 

Who can perform the evaluation?

The evaluation must be completed by an evaluator qualified under New Mexico regulations and submitted to NMED on the approved evaluation form. Reports must be filed with NMED within 15 days.

What if the system is unpermitted?

If the owner cannot provide a permit and NMED cannot locate one, the system is considered unpermitted. It must be inspected and may need to be registered or permitted. If deficiencies are found, corrective action and permitting may be required.

What if the system fails?

If the evaluation identifies deficiencies or permit violations, the owner must submit permit applications and correct the issues, typically within 15 days of the evaluation report.

Advanced Treatment Systems (Aerobic Systems)

For advanced treatment systems, additional requirements apply:

• Sampling results must be included if required under the permit.
• Ownership transfer requires a permit amendment.
• The new owner must provide a maintenance contract.
