New water-filter factory in Ghana
In northern Ghana, that nations poorest and most rural region, most families get their drinking water from rivers or large, shallow ponds. The water in these bodies, which are also used by livestock, is clouded with sediment and teeming with bacteria and parasites.
MIT Senior Lecturer in Civil and Environmental Engineering Susan Murcott 90, SM 92 has spent years trying to combat the widespread disease caused by poor water quality in many developing countries. This spring that work took a major leap forward with the long-awaited completion of a Ghanaian factory to produce thousands of inexpensive water-filtration systems.
A billion people lack safe water around the world, Murcott says. But when she began teaching at MIT in the 1990s, there was little opportunity for students here or anywhere in the United States to work on the problems of water and sanitation in developing countries. In my undergraduate and graduate years here, it wasnt mentioned, she recalls. Since then, scores of MIT students have participated in projects to improve water and sanitation in various developing countries. A number of Murcotts students have won prizes for their work, including three teams who won a total of $22,500 in this years IDEAS Competition and Global Challenge.
The new factory will churn out filters that use a porous ceramic pot to filter sediment and bacteria out of the water. The flowerpot-like filter is set into the top of a plastic barrel, which is fitted with a spigot at the bottom to dispense the water. Murcott co-founded a nonprofit company in 2005, called Pure Home Water, to start selling the filters, which were produced under contract in Accra, Ghanas capital. So far, more than 16,000 have been sold, providing clean water to an estimated 100,000 people.
After serious problems with quality control and with breakage during the rough 12-hour truck ride to deliver the filters to where they were needed, Murcott decided to set up the factory in northern Ghana, the area where the need was greatest. After more than a year of work, aided by Murcott and more than a dozen MIT students, the factory was completed in March, and is now beginning to churn out filters at a rate of 200 per month, with a goal of 350 units a month by the end of this year. The factory will also make bricks, using the same clay and kilns, which will be sold to help subsidize the filter production. The filter systems will be sold for about $10 each.
