WSP have sponsored Solvatten since 2010. Now Solvatten is a showcase for WSP for how design can adress the issue of access to safe and hot water at home – in a portable and environmentally friendly way. WSPs employes have been participating in a lottery to win a trip to Kenya and visit Solvatten project sites. Johanna Felix, Oliwer and David Wadstrom from the Solvatten team guided  WSPs Annica Renman and Eva Högvalls through two locations where families use Solvatten in 1) Bungoma (with the NGO Vi -Agroforestry)  and 2) Nairobi, Kibera (with the NGO IEW). The winners wrote a blog about their experience here. http://solvattenresan.wordpress.com/ (in swedish)
