Drainage systems make wastewater disappear whenever toilets are flushed or hands are washed in buildings and residential properties
But for all the functions that drainage helps make possible—dishes, laundry, showers—few people stop and think about the mechanisms that go into the process
Sewers and septic systems both filter out black water — the water you flush — and grey water, which comes out of sink and shower drains. In terms of sanitation, both systems filter bacteria and pathogens from water before it flows back out into the environment. Basically, the two systems both offer reliable drainage of wastewater from houses and buildings with minimal problems the majority of the time.
Consequently, sewer and septic pipes can sometimes get clogged with grease, hair, and hard elements, all of which can cause sewage to plug up sinks, toilets, and bathtubs. These problems usually come down to maintenance. When not adequately maintained, the outflow can be detrimental to lake water purity and hazardous to the surrounding environment.
