Swiss Rivers Transform From Health Hazards to ‘Blue Gold’
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Switzerland transformed its once-polluted waterways into clean, swimmable rivers and lakes through strict environmental laws, modern sewage treatment, and sustained public investment.
📈 One key stat: Today 98% of Swiss citizens connect to wastewater treatment plants, compared to just 14% in 1965, showing remarkable progress in water infrastructure development.
💬 One key quote: “We are united by a love of water. If you don’t have friends, you lock yourself in your house and get depressed. Here is the ideal medicine—cold water and friends,” says Pascal Baudin, a retiree who swims daily with a local club.
1️⃣ The big picture: Switzerland has achieved an environmental turnaround that many nations envy, transforming its severely polluted waterways into some of Europe’s cleanest waters. This dramatic change began after a deadly typhoid outbreak in 1963 prompted the government to implement strict wastewater laws. Over several decades, the country invested heavily in modern sewage infrastructure, connecting nearly all citizens to treatment plants. Swiss rivers that once carried raw sewage and industrial waste now serve as recreational spaces where people swim daily, even in urban centers like Geneva and Zurich.
2️⃣ Why is this good news: Rivers and lakes throughout Switzerland now provide clean, safe spaces for recreation, improving public health and quality of life for residents. The country leads globally in tackling micropollutants—trace pharmaceuticals and chemicals that traditional treatment misses—by implementing advanced filtration technologies like activated charcoal. This environmental success has united Swiss citizens around their waterways, creating community spaces that enhance social connections and wellbeing. The comprehensive approach to water protection demonstrates that severely degraded ecosystems can recover with proper investment and regulation, offering hope to other nations facing similar challenges.
3️⃣ What’s next: Switzerland aims to upgrade all major treatment plants with micropollutant filters by 2040, with 37 facilities already equipped. Engineers advocate for banning the most persistent pollutants that resist even advanced treatment methods. The Swiss model now inspires European policy, with the US requiring large wastewater plants to filter micropollutants by 2045.
