Work slogans:

• Start with yourself

• What one man can do another man can do

• Simple things are not simple

• Benefits from sanitation:  B & B (Biogas and Banana)

• Learn from nature (How did the apple come on the tree?)

WASAZA (Water and Sanitation Association of Zambia) is a partnership association with 320 members. We train and capacitate professionals in the water and sanitation sector. Present emphasis is on the introduction of alternative (ecological) sanitation methods in Zambia. This happens in close cooperation with WASAZA´s main Partner BORDA (Bremen Overseas Research and Development Association).
