For my ACT4 post, I decided to write about Grameen-Veolia Water Ltd.
, a joint venture between Grameen's health and hygiene subsidiary and Veolia Water, a French company. Operated as a social business venture (similar to the joint venture between Grameen and Danone I would imagine) the water purification plant provides water to the area at a nominal cost, which helps to maintain the facility and plan expansion into other areas.
Before going on, I should probably mention why Bangladesh in particular is in such desperate need of such a service. While water (as far as I know) is not scare in Bangladesh, it tends to be highly contaminated with arsenic. This isn't the fault of any man-made phenomenon, but rather a geological one. As a result, most of Bangladesh's water is dangerous, or even lethal to drink.
As far as what to advocate Grameen or Veolia do to increase their impact? Both are highly skilled companies, and Grameen in particular has decades of experience with similar, very successful, projects. My only hope, then, is that they are actively encouraging replicator projects in other areas, so that everyone can benefit from what seems to be a very effective approach. I am also going to try to apply to the Grameen Creative Lab to see if there is a more direct way I can contribute.
