Waste Water System Session 1: Waste Water System Overview

The waste water system in all RVs consists of separate tanks to hold the waste from the toilet, referred to as the Black Water Tank, and cleaner waste water from the shower and faucets, known as the Gray Water Tanks. Some models, especially trailers with two bathrooms, will have more than one tank for each system. These tanks are emptied by a spade valve connected to a dump hose and a dump station.
