Where wastewater goes once you are no longer using it depends on whether your plumbing is connected to a private septic system or a public sewage line.

A septic system is normally used for wastewater treatment in areas where public sewage service is not available, such as rural areas.  In areas where public sewage treatment is available, homes are usually linked to the public system by pipelines that take waste to a wastewater treatment plant that serves an area.
