SDG 6 (Sustainable Development Goal 6) aims to ensure availability and sustainable management of water and sanitation for all. This includes targets such as achieving universal and equitable access to safe and affordable drinking water, improving water quality, and increasing water-use efficiency.

Despite progress in some areas, many challenges remain in achieving SDG 6. For example, billions of people still lack access to basic water and sanitation services, and water scarcity and pollution continue to be major issues in many parts of the world.

Addressing the challenges of SDG 6 requires a range of actions, including improving infrastructure and service delivery, promoting sustainable water use and management practices, and strengthening governance and financing mechanisms. It also requires addressing the social and environmental dimensions of water and sanitation, such as gender equality, climate change, and ecosystem protection.
