Components of an individual septic system:Plumbing from sources
of wastewater to tank.Septic tank(s); may include pump tank must be
pumped
periodically to remove septage, which must be dispersed of bythe
pumper.
If pre-treatment option is installed, goes after the tank.
If not gravity fed, pumps, lift stations, other mechanical
parts.If gravity fed, drop box(s) to distribute to soil treatment
area.Soil treatment area may be in-ground system, at-grade or

Mechanical Treatment PlantCollects wastewater from multiple
homes and businesses
via any of the wastewater collection systems (see pages 2and 3)
without tanks.
Sewage (solids and liquids) are piped, usually via gravityto a
treatment plant. See page 5 for the most commonoptions in
Minnesota.
Treated wastewater is discharged, usually to local
surfacewaters.Most systems have bio-solids or sludge that must
bedispersed of periodically.
Cluster Septic SystemCollects wastewater from multiple homes via
any of the
wastewater collection systems (see pages 2 and 3). Systemmay
include small businesses, or may only serve a businesssuch as
resort, gas station or restaurant.
Tanks may be installed for each home, or may serve more thanone
home.Wastewater is usually (not always) piped to a
pre-treatmentsystem, which often includes larger collection tanks
before thesystem. See pages 3 4 for information on pre-treatment
options.Wastewater goes to a final treatment/dispersal system may
besubsurface or surface soil based, or surface water based.
Seepages 6 7 for information.
