In Togo’s Plateaux Region the two villages Bouré and Iko-Akpa enjoy improved access to valuable clean water. Instead of pumping the water by hand there is now an electric pump powered by photovoltaics and saltwater batteries.
What’s the current situation in Togo? In Togo, there are around 10,000 villages with less than 1,500 inhabitants and these villages are primarily served with hand pumps. The hand pumps are installed and supervised by the local water authorities who also demand that each village elects a water committee (called AUSEPA) and makes sure that each household pays for the water. This makes the local water authorities an important player: They are actively involved in water projects in the Plateaux region.
Why use saltwater batteries for that project? For applications in remote regions saltwater batteries prove to be the first choice as their capability of 100% depth of discharge and maintenance free nature make them easy to use in areas where system access is costly and time consuming. For those applications a robust battery is valuable. Further high temperature tolerance is important for such areas. Besides the robustness of saltwater batteries the safety aspect and environmentally friendly nature are important decision factors. Saltwater batteries are non-flammable, non-explosive and are made out of non-toxic materials.
Success Factor | Hero Moment
Success factor in this project was definitely the Poul Due Jensen Foundation (www.pdjf.dk/en). They engaged with the local authorities and people in the villages. With their initiative the project came to life. It is great to see how this installation makes life for the people of two villages easier. Instead of strenuous hand pumping the clean water runs easily.
