Greywater in Africa

I just returned from meetings at the recently-opened WWAP Headquarters at the Villa La Colombella in Perugia, Italy. This is an incredible place to hold a meeting, with 5-star accomodations, 5-star staff, 5-star views, and the usual 5-star Italian restaurants within short walks - the La Locanda dei Golosi is one which has so many varieties of pizzas that I started an English translation of their menu. This facility will quickly become the "go-to" place for all world water meetings, even those focusing on the arcane topic of greywater reuse.

While in Colombella, colleague and friend Greg Christelis, Deputy Director of Geohydrology for the  Namibian Ministry of Agriculture, Water and Forestry, shared some of his work on the ambitious efforts to supply water in Namibia, the driest country in Sub-Saharan Africa. As shown in the graphic, greywater is an important part of the water portfolio for agricultural irrigation. Note the costs are slightly more than groundwater (costs are in Namibian dollars, with a currency conversion leading to $USD 0.67 per cubic meter (about 264 gallons) for those fussy water economists out there).

Great venue, great meetings, great food, great wine, great friends, and greywater all in one place. Eccellente!
