Solar-powered water purification system a huge success in Mexican village : TreeHugger

The remote jungle village of La Mancalona on the Yucatan peninsula of Mexico has gone from a place where clean water was scarce, bottled water expensive and soda much cheaper to a place where they have a reliable source of purified water and a profitable business in just two years.This positive change is thanks to an MIT-designed solar-powered water purification system that the village was the first to take for a test drive.The reverse osmosis system consists of two photovoltaic solar panels that power a set of pumps that push both brackish well water and collected rain water through semiporous membranes that filter and purify the water. The system produces about 1,000 liters of clean water a day for the village’s 450 residents.La Mancalona was chosen as a test site because of its lack of clean water sources and its ample year-round sunshine. The village also had another asset: its residents are mainly subsistence farmers who are very handy and could operate the system on their own.”When you live in a very rural area, you have to do everything yourself,” said MIT researcher Huda Elasaad. “Farming, if there’s something wrong with your well, you’re the one stuck fixing it, because no one’s going to drive into the jungle to help you. So they were very handy, which made it easy for us to train them.”
