Day 9 - A Tale of Two Cities: Visiting China's Premier Water Treatment Plant
On our 9th day, for a few brief hours, we ceased being tourists or budding environmentalists and placed ourselves in the shoes of ordinary Chinese citizens.
Visiting the Beijing Gao Bei Dian Water treatment facility allowed us to see the toll pollution and the water crisis is taking on human lives.To get to Gao Bei Dian from our neighborhood requires Herculean effort: you must get on the metro, transfer at least 3 times, get on an overcrowded, sweltering one-stop bus that takes almost thirty minutes to reach the final-and only-destination.
We walked through the bleakest neighborhood we have seen during our trip to arrive at the contrastingly beautiful water treatment facility. The facility is everything its surrounding neighborhood is not: green, lush, flourishing, modern, optimistic.
After being escorted to a bright, airy auditorium by our smiling, polite guide, we watched a slickly crafted video on the importance of water conservation in China and the international partnerships between the Chinese government and leading organizations around the world. The video revealed that the plant was the largest of its kind in the country, with the major function of minimizing pollution in order to make the water usable.
Following the video, we toured the exhibition hall, a technological marvel that not only showcases the efforts of the plant but also explains the water treatment process through a simple, multi-sensory approach. There are mainly two steps to water treatment: primary and secondary. Primary treatment, which is the physical treatment of the water, is the removal of sludge and sediment. Secondary treatment involves the chemical and biological treatment of the water.
Though the exhibition included a detailed physical model of the plant, the highlight of our visit was when we were able to tour the plant ourselves. Despite the stench of raw sewage-which led us to quickly rename the facility the stinky place-we learned hands on the core steps to the process. The sites we visited were part of the primary water treatment. First, we viewed the bar screen, where sludge is separated from water. (That site really requires a strong constitution-and possibly a stuffy nose.) Fortunately, we survived the smell and were able to move on the aeration tank. There, air is pumped into the water to separate sludge and grit, a cappuccino of sorts, with equal parts sludge and grime. Finally, this process leads to the Reuse Water tank, which is clean enough to sustain baby koi.
A few students-Allen, Tykia, and Alexis-were lucky enough to conduct a little experiment. Stirring a sediment solution for 30 seconds, watching a liquid turn into a solid, the group got a chance to observe a chemical change first hand.
While we were immersed in the world of the water treatment plant, we put aside the inequities we were confronted with during our bus ride and our walk through the neighborhood. But this was short lived. As soon as we left the plant, the disparity hit us right in the face. Most of us walked away asking questions about how to balance rapid economic growth with environmental justice for all. We all ended our day at the facility with the recognition that clean water is a basic human right-no matter what side of the city you find yourself living in.
