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.
