Sources of Drain Water

Water drainage is an essential part of our daily lives, but many of us don’t know where it all comes from. Sources of drain water include rainwater runoff, wastewater from kitchens, bathrooms, and laundry, and water from other household appliances. Rainwater runoff is the most common source of drain water, as it is collected from surfaces such as rooftops, sidewalks, and streets. Wastewater from kitchens, bathrooms, and laundry is collected from sinks, showers, and washing machines, respectively. Finally, water from other household appliances such as dishwashers and water heaters may also be collected and drained away. In short, drain water comes from a variety of sources, all of which are necessary for us to keep our homes and communities clean and functioning properly.

Possible Contaminants in Drain Water
