Overview

Students discover for
themselves the process that sewage and wastewater takes in a wastewater treatment plant before it
is safely returned to our waterways. This hands-on activity takes them through the processes without
leaving the premises. A model of a Water Treatment Centre is used. Photos of actual local treatment
plants are included for relating to the working model.
