Rationale
Why SCDIO exists
Despite national progress, many rural and disadvantaged communities in Tanzania still lack reliable access to safe water, sanitation, and hygiene services. Infrastructure projects often fail due to limited community ownership, inadequate environmental considerations, and weak maintenance systems. SCDIO was established to bridge this gap.
