Onsite Wastewater Training Center
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.
