The World Bank is spending $ 64M to upgrade Metro Manila's sewers. I wish there was a citizen's voice or a green group that would find a place on the table.
The picture above is from Baima, China. It's a living machine -a constructed wetland that cleans an urban creek. Can you imagine something like this on the Pasig River, the Marikina River or on Tripa de Galina?
"In Baima, China, a series of canals (top) used to collect and channel sewage, commercial wastewater, and stormwater runoff threatened the health of the city's 6 million inhabitants. After just two months, a Restorer system supporting 12,000 plants of 20 native species (bottom) is reducing odors, eliminating solids, improving water clarity, and reducing bacteria in the effluent that flows to the area's major river."
