Final answer:
The Bio-Filtration System helps the environment by preventing water from overflowing into storm drains, thus reducing water pollution. The correct option is D) Overflowing into storm drains
Step-by-step explanation:
The Bio-Filtration System helps the environment by keeping water from overflowing into storm drains. These systems use layers of sand, gravel, and charcoal to remove small particles from the water through filtration, followed by disinfection before storage.
This prevents untreated water, which may include various pollutants and potentially harmful pathogens, from being released into the environment. The bio-filtration process aligns with the broader goals of wastewater treatment to reduce pollution and protect ecosystems.
Proper sewage treatment includes multiple stages, such as sedimentation, aeration, floc settling, and disinfection, intended to eliminate organic matter and kill harmful microorganisms.
Some of the treated water may be reused for irrigation or habitat preservation, contributing to water conservation efforts and supporting the natural water cycle. The correct option is D) Overflowing into storm drains
