Why Do We Need a
Wastewater Collection System?
Whenever you flush
your toilet or wash something down the drain, you create wastewater,
commonly known as sewage. You might ask the question: why not just dump
this wastewater onto the ground or into the nearest ditch, lake, stream or
river? There are three things about wastewater that make it an undesirable
addition to the environment.
- Wastewater smells
bad. When released into the environment things begin to smell bad very
quickly.
- Wastewater
contains harmful bacteria. Human waste naturally contains coliform
bacteria, such as E. coli. Once infected with this bacteria the water
becomes a health hazard.
- Wastewater
contains suspended soilds and chemicals that can adversely affect the
environment. As an example, wastewater contains nitrogen and
phosphates that, being fertilizers, encourage the growth of algae.
Excessive algae can block sunlight and foul the water. When algae dies
it also consumes oxygen in the decomposition process that is needed by
aquatic life. As oxygen levels in the water decrease so does the
amount and diversity of aquatic life. Wastewater also contains organic
material that consume oxygen when bacteria starts to break it down.
Do you want to live
in an environment that smells bad, is full of deadly bacteria, and cannot
support aquatic life? The answer is that no one really does. This is why
we have wastewater collection systems, wastewater treatment plants and
laws that prohibit the release of raw sewage into the environment.
