Why should we treat ecologically our wastewater?

 

Usually, nature does things well. It cleans wastewater on its own; it is called self-purification, but the fact is that right now, nature is overflowed. Across the world, approximatively 1.8 billion of people drink water contaminated with faecal coliforms. Also, more then 80% of wastewater generated by human activity are released into watercourses, rivers, and oceans without any treatment which leads to heavy pollution.

Improper wastewater management can generate several consequences including: : 

  • Human water-borne diseases: Cholera, dysentery, typhoid fever, poliomyelitis, Hepatitis A and E and diarrhea are the most frequent.
  • Significant costs in terms of water decontamination.
  • Increase of blue-green algae in our waters which cause gastroenteritis, headaches and skin irritations.
  • Eutrophication in aquatic environments (regression and mortality of aquatic species)
  • Farm animals carrying diseases.
  • And many more

There is a green wave growing in Quebec and all around the world. More and more people are joining it. We need to treat wastewater in a responsible manner to preserve the balance of nature.
