“Sometimes toilets and taps are not working for months and even years. If we don’t fix them, no one will.”

IWSH ZA Locations IWSH ZA Communities IWSH ZA Works


IWSH supports community plumbing collective WASSUP Diepsloot – the Water Amenities Sanitation Services Upgrade Program – to upgrade and maintain communal toilets and taps in densely-populated township settings in Gauteng Province.

At IAPMO, we measure our success in lives, water and total lifecycle costs saved, contributing to strong healthy communities. Our non-profit arm, the International Water, Sanitation and Hygiene Foundation (IWSH) assembles teams of skilled plumbing volunteers to improve access to water, sanitation and hygiene for a variety of communities in need. We connect with local leaders, governmental and nonprofit partners, labor organizations, and manufacturers.
