How do we treat our wastewater?
Water used in homes, schools, businesses, and industries must be cleaned or treated before it can be used again or returned to the environment. No matter where you live, in an urban or rural setting, the water you use does not just disappear: it is piped to a treatment system. The treatment of wastewater is important to keeping our water clean. This poster depicts what happens to the water we all use and how wastewater is treated so that it can be used again. The poster is folded Into 8-1/2 by 11-inch panels; front and back panels can easily be photocopied.
