SEED-supported enterprises in the water, sanitation and health (WASH) sector designed products and services that support healthy and sustainable livelihoods through improved water security and greater access to adequate sanitation facilities. Exemplary enterprises in the sector offer biodegradable female sanitary products, hygienic toilet systems that convert waste to energy, community-owned water networks capitalising on local partnerships and more.
