WEHDI believes in working in partnership with other like-minded specialized individuals, institutions (both public and private) in order to deliver sustainable water and environmental programmes/initiatives that lead to positive outcomes for sustainable human development. WEHDI membership takes several forms:

​

1. Institutional affiliation 

2. Institutions that collaborate on consortium to undertake specific programmes

3. Individual members with expertise and/or interest in WEHDI's areas of work

4. Volunteers

​

WEHDI Members stay informed about activities and information (reports, research, applications, tools, products and services) on water and related environmental issues. WEHDI membership is an investment in improved programme management capacity, organised by donations and in-kind contributions, ensuring sustainable programme development and management. Through joint efforts, we contribute to strategic international, regional and national water and related ecosystem debates to help set the agenda and develop joint responses for addressing socio-economic and environmental problems.
