DEFINITION OF TERMS

and urine
EXCRETA
DRAINAGE SYSTEM
■ drainage pipes of a plumbing system taking the waste water from
the plumbing fixtures and delivering it to the sewer or some other
outlet
■ includes all of the piping within a private or public property that
conveys sewage, rainwater, and other liquid waste to a point of
disposal

SEPTIC SYSTEM

Septic System
■ highly efficient, self-contained, underground wastewater
treatment system
■ often more economical than centralized sewer systems in rural
areas where lot sizes are larger
■ simple in design (less expensive to install and maintain)
■ less disruptive to the environment

Septic System
SIX MAIN PARTS
■ sewer pipe from house to septic tank
■ septic tank to settle solids and
suspend oils
■ sewer pipe from tank to distribution
box
■ distribution box to evenly distribute
flows to each leg of leach field pipe
■ leach field to drain the effluent
water into the soil
■ soil to receive the effluent

HOW DO SEPTIC
SYSTEMS WORK?

How do septic systems work?
■ Septic system receives wastewater from the house.
■ Sewer pipe drains to the septic tank.
■ Septic tank separates solids from the wastewater, stores and partially
decomposes as much solid material as possible, while allowing the
liquid effluent to go to the drain field.

How do septic systems work?
■ Biological growth occurs when
the effluent drains into the soil. A
biological mat grows on the soil
that receives the effluent. This
biological mat is important as it
functions to treat the effluent.
