Local WASH centres are worth the long-term investment. Long-term follow-up support after training is vital to effective capacity development of an individual, especially in the case of entrepreneurs, who often encounter business challenges. Locally embedded centres can reach people that an external organization cannot: Grounded networks, know-how, and understanding of the context are invaluable and not replicable. Engrained local organisations are a rich source of knowledge about endogenous best, second best, and worst practices.
