We Are All 'Downstream': Understanding Water Reuse
The majority of the world's population drinks from rivers and streams that have received discharges from upstream users. In most of the industrialized developed world, there are treated wastewater discharges that become a source of drinking water supply for downstream users. It is nothing new. We've been doing it for centuries. What is new is that today's technology makes it cleaner and safer. Water reuse is the key to a sustainable future.
