We see on-site treatment, wastewater treatment and re-use as a game changer in the economy, especially now (given the drought in large parts of the country that seems to be never ending).
There can be more jobs created in manufacturing, selling, installation and maintenance of these kinds of systems. The bigger advantage is for the communities, though. They have the benefit of the water for generations to come. That can sustain small scale farming, sports facilities, etc, etc. Businesses can remain open because there will be water for toilet flushing. Garden services may continue because there is water for irrigation. (Remember many of the smaller towns don’t have piped sewage, others have evaporation ponds, so all of that water goes to waste.)
We need to look at this more inclusively. If we look at one fraction – the plant – only, we miss the bigger picture.
