What is Wastewater?
Wastewater is the liquid or liquid-borne waste discharge from any facility, building, or dwelling that enters a sewer system. Wastewater generates from both domestic and non-domestic sources. Domestic wastewater is the wastewater generated by households and from the kitchens and bathrooms of commercial or industrial facilities. Non-domestic wastewater is the wastewater generated from any other source such as industrial processes or operations.
