They treat wastewater with solar energy, capture CO2 and transform pollutants into valuable compounds. Moreover, they reproduce on their own and can collaborate in water disinfection. They are microalgae, plants we still know very little about, which can surely provide many benefits to sustainable sanitation without technological gaps.
The destruction of the Tanjaro River ecosystem shows that all is lost when water is polluted. Its recovery is also becoming an example of the difficulties of governance in a country that has not recovered from several wars. The short film Tanjaro is Dying, finalist of the We Art Water Film Festival 5, shows the disastrous consequences of the uncontrolled growth of a city in a region that has almost no memory of peace.
In regions with a lack of sanitation, DEWATS provides the possibility of a nature-based, low-cost and sustainable wastewater treatment without a sewage network. In partnership with World Vision, the Foundation is implementing it in a hospital in Chengelpattu, India.
The degradation of the Mithi River has become an icon of water pollution, a definite and poignant image of the worst end for waste caused by human activity, especially that of the poorest neighborhoods. The micro documentary Plastic River, finalist of the We Are Water Film Festival 5, covers the best images of this indecency. Finding out the reasons for this disaster is as important as learning from the efforts made to solve it.
Floods caused by violent rainfall frequently exceed the capacity of the sewage system and spill all kinds of pollutants into rivers and seas. Adapting urban sanitation systems to these phenomena is vital for the health and preservation of the environment. It is one of the challenges of the smart age in the face of an increasingly urban future. Investments must reach all for results to be sustainable.
Plastic is inherent in the lifestyle of most of the population and it is causing a disastrous environmental damage in which the duality garbage-water is at the same time cause and effect. The industry that has most changed our lifestyle is at a crossroads in which the future of the sustainability of the economy and the environment of the planet is decided.
Toilets define a dual scope of responsibility: we must bring them to everyone and we must use them correctly. Having one is a demand for health, dignity and hope for economic development for more than 4.2 billion people. Those who already have one are obliged to a responsible use, essential for the proper functioning of the water cycle and a key factor for the adaptation to climate change.
The short film by the Colombian Nicolás Durán, winner in the micro-documentary category of the We Art Water Film Festival 4, is a beautiful tribute to pure water, an immense gift of nature that is increasingly rare to find unless we climb to the top of the mountains. In Colombia and all around the world, it is urgent that we act as the protagonist of the short film, who changed his attitude to be coherent with his thinking.
