The German Water Partnership (GWP) is a joint initiative of enterprises and organisations from the German water industry and research sector and brings together their combined experience and skills. At the same time, it is the point of contact for partners abroad in all matters concerning the German water industry. The aim of the network, which was founded in April 2008 and is supported by five German ministries, is to establish German expertise and the quality label “Made in Germany” worldwide and to work together to strengthen the position of the German water industry in the international market.
