Water pollution is a constant problem in urban areas, but places like Osaka, Japan have come up with creative and green ways to clean up their water. On the Dontonbori canal, Osaka has installed floating solar-powered water purifiers that clean 2,400 liters of the river water per day. (And, yes, they look like UFOs.)

Waste water treatment plants can reuse waste water by purifying and using it for manufacturing, air conditioning and other non--potable purposes. Singapore’s waste water plant is one of the largest in the world and produces half of the country’s recycled waste water needs. Click here to find out more about Dow’s water solutions
In water-stressed coastal regions, cities are increasingly using Dow’s energy-efficient reverse osmosis technology to remove the salt from ocean water, making it fresh and drinkable. The city of Tampa, Florida, has the largest such desalination plant in the US. It’s capable of producing 25 million gallons of clean water a day.
