first action: let's change our relationship with water in cities
Understanding the water cycle, which means knowing where water we consume comes from and where it goes after we use it.
Being aware that we are channels of water and that we belong to the water cycle. Water flows through our body cleaning it the same way it does on the rest of the planet.
Putting rivers in the leading role. Rivers are the best path for our reconnection with nature. They act as mirrors of our choices. Clean rivers are a sign of urban health.
second action: let's reveal the current sanitation system
Discovering the natural system of buried rivers. Just because rivers are buried in cities, it doesn't mean they don't exist. They are flowing underground, and it becomes more evident when it rains, because of floods. Discover hidden rivers helps bring awareness about the system.
 
Bringing transparency to the current structure made of pipes, tubes and treatment plants. Nowadays, we are not able to check if the system works properly. System transparency will help us have more control over the whole process and ask for changes, when necessary.
third action: let's boost a new design for water sanitation with a more distributed approach
Promoting education addressing diffuse pollution. Both citizens and municipality are responsible to stop polluting rivers with all kind of trash we produce in urban lifestyle.
 
Becoming more self-contained in finding solutions for water treatment. The greatest benefit in having distributed systems is that they enable sewage treatment to be done near the place it is produced. The result is less sewer flowing underneath the city, reducing chances of leakage and ground water pollution. It also allows customized solutions for different situations and local control.
 
Promoting education addressing clandestine connections. Both citizens and municipality are responsible to stop polluting rivers with sewage. For example, usually people don't know how to check if houses or buildings are connected to the municipal sewer collection grid.
The implications of this change are clear.
Our struggle for global sustainability will be won or lost in cities.
