INSTALLER QUESTIONS AND
ANSWERS
Accessible community sewer - correct answers-Means a public sewerage system where it's utilization by
a given piece of property is not limited because of physical or other features as determined by the
commissioner
Advanced treatment system (ATS) - correct answers-Means an approved treatment device in
compliance with rule 0400-48-01-10 that is separate and distinct from the disposal field and is used to
improve the quality of septic thank effluent to secondary levels
Agency of government - correct answers-In the context of public sewerage systems, means state,
county, and municipal government agencies including their subdivisions and utility districts, but does
not include entities regulated by the Tennessee regulatory authority.
Air/Vacuum Relief Valves - correct answers-Means a device that allows the air in a distribution system to
escape during pressurized flow, and allows air to enter the system durning depressurized flow
Alternate methods of disposal - correct answers-Means a subsurface sewage disposal system, the
construction, installation, and operation of which varies from that of a conventional subsurface sewage
disposal system.
Blockout - correct answers-Means a potential access hole which is a think section of concrete preformed
in a septic tank which can be removed to allow insertion of a four to six inch pipe
Boundary outline - correct answers-Means a map or chart with lines delineating the boundaries of the
proposed area or parcel of land
, Buffer zone - correct answers-Means the distance between subsurface sewage disposal systems or
subsystems required to alleviate the impact of hydraulic overloading from the adjacent system
Commissioner - correct answers-Means the commissioner of environment and conservation, the
commissioners duly authorized representative, and in the event of commissioners absence or a vacancy
in the office of commissioner, the deputy commissioner
Comventional sand filter - correct answers-Means a filter with two(2) feet or more of medium sand
