Q
The diverted sewer system drains sewage and rainwater through separate sewers. What is the classification of sewage and rainwater?
Last Updated August 31, 2018
A
Sewage and rainwater can be classified as follows in principle.
Sewage is wastewater caused by living or business. Wastewater from flush toilets, kitchens, bathrooms, washrooms, laundry, and wastewater from factories, etc. are sewage.
Rainwater is a wastewater caused by natural phenomena such as rainfall. In addition to drainage from gutters during rainfall, spring water and snowmelt that come out on the surface of the ground are rainwater.
