The SDGs include the provision of safe drinking water and sanitation as one of its primary objectives since it is an essential human right. Women and girls in India's urban slums still suffer serious safety hazards due to the lack of proper sanitation, which has been the subject of several policy debates. Using findings from the National Sample Survey and other relevant studies, this investigation looks at the accessibility of water and sanitation facilities in the slums of Delhi. The results show that physical and sexual assault occurs when 30% of marginalised women use public restrooms, and that 70% of adolescent girls endure daily humiliation. Also, many teenage females stop going to school because of the lack of proper sanitation. Despite advancements in slum infrastructure, ensuring access to safe and clean sanitation continues to be a significant concern. A practical answer to the problems of water shortages and inadequate plumbing is the installation of bio-toilets. If you're looking for a sustainable and safe alternative to public restrooms, bio-toilets are a great choice. In order to provide safe spaces for girls and women in slum regions, this article stresses the critical requirement of government agencies and NGOs working together to install environmentally friendly bio-toilets.
