Whenever the use of a septic system is discontinued following connection to a municipal or private sanitary sewer or shared on-site system or following condemnation or demolition of a building served by the system, the system shall be considered abandoned, and any further use of the system for any purpose shall be prohibited unless, after inspection, the Board of Health determines the system is in compliance or can be brought into compliance with 310 CMR 15.000, State Environmental Code, Title V.
Continued use of a septic tank or any other septic system component, where the component is to become an integral part of a drainage system or other sanitary system, requires prior written approval from the Board of Health.
Any component of the septic system with a depth of one foot or greater shall be considered as a component which shall be properly abandoned in accordance with this Section.
The following procedure shall be used to abandon septic system components:
Within 14 days prior to discontinuance of use of a septic system, the facility owner shall apply to the Public Health Division to abandon the existing septic system components citing the reason(s) abandonment is necessary, and where connection to a municipal or private sanitary sewer has been made, a copy of the sewer connection permit shall be submitted with the application;
Upon receipt of a permit from the Public Health Division to abandon the system, the septic system components shall be pumped of their contents by a licensed septage hauler; and
The septic system components shall be excavated and removed from the site, or the bottom of the septic system components shall be opened or ruptured, after being pumped of their contents so as to prevent retainage of water and the components shall be completely filled with clean sand or other suitable material approved, in writing, by the Board of Health.
