IWA Specialist Group “Ecological Sanitation”

IWA has its roots in two strong associations: the International Water Supply Association (IWSA) and the International Water Quality Association (IAWQ). IWSA was established in 1947 while IAWQ was originally formed as the International Association for Water Pollution Research in 1965. IWSA and IAWQ came together in a merger in 1999 to form IWA.

Today, IWA is a member driven organization. There are three member types within the Association: Individual, Corporate and Governing Members. The Association is a non-profit organization, self-governing and responsible to its Governing Members.

IWA’s Vision is connecting water professionals worldwide to lead the development of effective and sustainable approaches to water management.



The overall goal of EcoSanRes is to create a global confidence in ecological sanitation as a trustworthy, affordable and sustainable alternative for design of sanitation systems. This requires a new understanding of sanitation, a holistic system based on healthy ecosystems. Residual material is recycled and reused as part of an ecocycle process. External inputs into the system and “wastes” that exit the system are reduced to a minimum or eliminated. Very little water or no water is used. Excreta are processed and rendered safe, close to the point of excretion, pollution is minimized, protecting ground and surface water, and nutrients and carbon are returned to land and made productive, which implies closing the loop. The holistic and ecological approach becomes safe and non-polluting. It can be gender and culturally acceptable; economically feasible; environmentally sustainable; and protecting and preserving the local ecosystem.



The site focuses on Ecological Sanitation especially in urban areas. The site provides information on the technical, financial, environmental, health, socio-cultural,institutional, political and legal aspects important for the success of (ecological) sanitation.




Eco Solutions promotes and demonstrates community focussed initiatives in water-, soil-, sanitation- and health-security. We believe that development initiatives that ignore the importance of the community and household-centred approaches are unsustainable. People themselves are the primary energy for change. Women particularly are endowed with generations of knowledge and skills in nurture, household survival and environmental sustainability. eco-solutions listens to and works with such people. By adding the extra building blocks of skill and know-how that may be absent, due to lack of exposure and education, eco-solutions strengthens people’s power to build sustainable solutions for today and the future.
