Conventional Gravity Systems

The two conventional systems that are on display were designed for a wastewater loading rate that is typical for a three bedroom home.  Each system is partially elevated to allow trainees to view all the components of a properly installed system.  During training sessions potable water, which simulates wastewater, flows through each system.
