The Rural Water Supply Network is a network with global outreach among almost 10,000 practitioners in the water sector. Within this network, Skat was responsible for the set-up and development of one of the Themes: Self-supply. The term was coined by RWSN and refers to an approach under which people upgrade their water and sanitation services, chiefly financed by themselves.

In 2012, Skat took over the leadership of this Theme and continued the development of the concepts and contents related to it. During this time the concept has become increasingly recognized as an important part of the puzzle to improve water and sanitation services, particularly for – but not limited to – remote rural areas.
