Migrant communities and women in Indian urban areas face several sanitation challenges. These challenges include inadequate access to clean toilets, concerns about privacy, water shortages, poor maintenance and issues related to menstrual hygiene, impacting health and dignity. In 2018, PVR NEST launched a groundbreaking initiative in Vikaspuri in Delhi, collaborating with the National Commission for Protection of Child Rights (NCPCR) and the municipal corporation of Delhi (MCD), to build the pink toilet.
