It is exactly what it is. Wastewater is water that is wasted. Without even realizing it, many consumers continue to waste water unnecessarily. Take what you would have thought is the simple process of brushing your teeth in the morning. In this case, many people continue to have that nasty habit of leaving the tap running while brushing their teeth. Critical water shortages being experienced around the world, this is extremely wasteful. So perhaps you can imagine the far more dramatic impact of wasted water in industry.
And as a result, not only must the waste of industrial water be contained, it must also be treated. This of course is as a result of the water used in industrial processes has high levels of toxicity and pollution. Now, because industrial use water is contaminated does not mean that it needs to be discarded forthwith. Instead, industrial wastewater treatment is cleaning the large volumes of water being used regularly. Speaking of which, instead of discarding or distributing the water elsewhere, the water can now be recycled internally and re-used, over and over again.
Domestic consumers not yet used to the process of recycling, re-using and treating their water really ought to give it a try. They will be able to experience the positive benefits of these renewable and environmentally friendly cycles within a matter of weeks. In fact, they can even collect water. Rainwater is now being caught in catchment areas holding large containers. Such water no longer needs to drain away wastefully.
Owing to its scale and the costs involved, industrialists have already gone some distance in endeavoring to contain and control their water usage. The domestic consumer following their good example will also soon experience the positive benefit of substantial lower household costs.
