Accessible community sewer - correct answerMeans 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 answerMeans 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 answerIn 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 answerMeans 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 answerMeans a subsurface sewage disposal
system, the construction, installation, and operation of which varies from that of a
conventional subsurface sewage disposal system.
Blockout - correct answerMeans 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 answerMeans a map or chart with lines delineating the
boundaries of the proposed area or parcel of land
Buffer zone - correct answerMeans the distance between subsurface sewage disposal
systems or subsystems required to alleviate the impact of hydraulic overloading from
the adjacent system
Commissioner - correct answerMeans 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 answerMeans a filter with two(2) feet or more of
medium sand designed to chemically and biologically process septic tank or other
, treatment unit effluent from a pressure distribution system operated on an intermittent
basis.
Conventional subsurface sewage, disposal system - correct answerMeans a disposal
system that pre-treat sewage by use of septic tank and applies effluent to the soil as
described in rule 0400-48-01-07
Department - correct answerMeans the department of environment and conservation
Disposal field - correct answerMeans the part of a subsurface sewage disposal system
that utilizes the soil for absorption and treatment of septic tank effluent
Domestic septage - correct answerMeans either liquid or solid material. Removed from
a septic tank, cesspool, portable, toilet, type III marine sanitation device, or similar
treatment Works, that receive only domestic sewage domestic septage does not include
liquid or solid material removed from a septic tank, cesspool or similar treatment works,
that receives either commercial wastewater or industrial waste water, and does not
include grease trap at a restaurant.
Dosing chamber - correct answerMeans a water tight receptacle which house is a
sewage effluent pump or siphon and stores sewage effluent from a septic tank until it is
pumped, or dosed to a disposal field.
Drip emitters - correct answerMeans a flow control device that is typically attached to
the inside wall of drip line, which allows the discharge of water at a predictable rate for a
given pressure
Drip line - correct answerMeans polyethylene tubing that has been certified for
wastewater. Use that incorporates uniformly spaced drip emitters along it's Length
Effluent filter - correct answerMeans an effluent treatment Device installed on the outlet
of a septic tank or dosing tank, which is designed to prevent the passage of large
suspended matter.
Filled land - correct answerMeans areas to which, more than 2 feet of Soil, and or
debris has been added
Fragipan - correct answerMeans natural subsurface horizon with high bulk density, and
or high mechanical Strength relative to the Solum above, seemingly cemented when
dry, but when moist showing a moderate to weak brittleness
Graded land - correct answerMeans areas from which soil has been removed and the
remaining soil cannot be classified in any soil series
Grease trap - correct answerMeans a device designed to intercept and retain grease
present in sewage or other waste water
