The additional financing will be utilized to expand parts of the ongoing Burkina Faso Urban Water Sector Project (UWSP).
About 434,000 additional people were allowed to access the piped water and 403,000 people benefited from enhanced sanitation services.
The urban water sector reform supported by the project is also being implemented, the World Bank said.
About 1.1 million people living in urban areas of Burkina Faso and informal settlements around Ouagadougou will benefit from the increase in the UWSP activities.
The additional financing will be used to develop the water distribution system in order to enhance service quality and make clean water accessible to earlier underserved areas.
Plans include the construction of secondary and tertiary water distribution pipes and about 26,000 water service connections and 80 public standpipes.
World Bank task team leader for the project Matar Fall said: "The additional financing will help build new water transmission lines, storage tanks and pumping stations to make clean water available throughout Ouagadougou, providing almost 760,000 people with access to improved water sources.
"It will also promote access to water for informal settlements where, until recently, water services were not provided."
