Most of the 4.5 million people in Nyanza Province rely on unsafe water sources to meet daily needs. As a result, diarrhea is a leading cause of morbidity and mortality, particularly for children <5 years old and people living with HIV/AIDS. Provision of water infrastructure is expensive and takes years to implement. Interventions that can protect and improve health in these populations, and thereby facilitate economic and social development, are needed now. The objective of the Rotary Safe Water Project (RSWP) is to decrease water related illnesses in Kenya?s Nyanza Province, and provide income generation for rural women, through sales of inexpensive household water treatment and safe storage (HWTS) products by rural HIV/AIDS self help groups to marginalized populations with minimal access to services. HWTS interventions have been proven to prevent diarrhea and death. Access to HWTS products has been difficult in Nyanza Province because poor roads make distribution difficult and poverty limits disposable income. By mobilizing local groups for product distribution, the project will improve access to HWTS.
