Tanzania Vision 2025 provides direction and a philosophy for long-term development. Tanzania wants to achieve by 2025 a high quality of livelihood for its citizens. It emphasizes the importance of water availability for the citizen, and it aims to provide Universal access to clean and safe water. However the sustainable development goals especially goal number six target making sure everyone has access to clean drinking water and toilet facilities. It is obvious that the water supply system in Tanzania especially in rural communities is facing water security risks in various aspects such as scarcity and quality. According to DHS (2016) Tanzania Mainland rural households obtain their drinking water from unimproved sources.

Community related intervention to reduce rural water system’s susceptibility to effects of climate variability and change; environmental challenges and other human activities so as to ensure continuous enough and safe supply of water to rural communities is needed.

OCE aims to enhance community’s adaptive capacity to withstand the effects of climate change.
