Septic System Knowledge Assessment

Septic systems are widely used for waste treatment in homes. They consist of a septic tank that captures solids and liquids, preventing solids from entering the disposal field. Gases from anaerobic digestion are vented out. Treated wastewater flows to a distribution box and into trenches, where it interacts with soil, forming a biomat. Regular maintenance, including pumping every three years, is crucial for system longevity and environmental protection.

What is the primary purpose of a septic system?

• To treat and manage household waste

• To cool down homes

• To provide drinking water

• To generate electricity

What does the primary compartment of a septic tank do?

• Generates electricity

• Stores clean water

• Captures solids and allows liquids to flow

• Filters air

What prevents solids from leaving the septic tank?

• The gravel bed

• The roof vents

• The baffle wall

• The outlet pipe

How are gases from anaerobic digestion managed in a septic system?

• They are released through the home's roof vents

• They are stored in a separate tank

• They are used to power the home

• They are converted into water

What is the role of a distribution box in a septic system?

• To generate electricity

• To distribute effluent to trenches

• To filter solids

• To store excess water

What forms at the bottom of a trench over time?

• A layer of sand

• A pool of clean water

• A biomat

• A gravel bed

What is the process called that promotes plant growth by moving water upward through soil pores?

• Filtration

• Photosynthesis

• Evapotranspiration

• Condensation

How often should septic tanks be pumped?

• Every year

• Every three years

• Every five years

• Every ten years

Why is it important to leave small amounts of solids in the septic tank after pumping?

• To reduce odors

• To save on pumping costs

• To establish healthy microbial levels

• To prevent tank overflow

What is the ultimate goal of understanding and maintaining septic systems?

• To increase property value

• To reduce water usage

• To improve air quality

• To protect public health and the environment
