His accomplishments span the fields of sanitation technology, social enterprise, and healthcare education for millions of people in his native country, serving as a model for NGO agencies and public health initiatives around the world.

Since he established the Sulabh Sanitation Movement in 1970, Dr. Pathak has worked to change social attitudes toward traditional unsanitary latrine practices in slums, rural villages, and dense urban districts, and developed cost effective toilet systems that have improved daily life and health for millions of people. He has also waged an ongoing campaign to abolish the traditional practice of manual “scavenging” of human waste from bucket latrines in India while championing the rights of former scavengers and their families to economic opportunity, decent standards of living, and social dignity.

“The results of Dr. Pathak’s endeavors constitute one of the most amazing examples of how one person can impact the well being of millions,” noted the Stockholm Water Prize nominating committee in its citation.

“Dr. Pathak’s leadership in attaining these remarkable socio-environmental results has been universally recognized, and not least by those who have secured the freedom of human dignity as a consequence of his efforts.”

Sanitation Innovator

Frequently citing the common toilet as one of civilization’s most significant advances, Dr. Pathak has led the development of cost-effective and culturally appropriate toilets and related treatment systems to replace the traditional unsanitary bucket latrines in poor communities throughout India. His most prominent innovations include:

• The Sulabh Shauchalaya twin pit, pour-flush toilet system now in use in more than 1.2 million residences and buildings built by Sulabh. This technology has been declared a Global Best Practice by United Nations HABITAT and Centre for Human Settlements, and is now recommended by the UNDP for use by more than 2.6 billion people around the world.
• Sulabh public toilet and bath facilities based on that system at 7500 locations, together serving more than 10 million people daily. These pay-per-use public facilities provide an economically sustainable, ecological, and culturally acceptable solution to hygiene problems in crowded slum communities and public places.
• Optimised water conservation in the Sulabh Shauchalaya systems, requiring only 1.5 litres of water per use to flush, in contrast to conventional toilets that require a minimum of 10 litres. This has significant additional benefits for health and quality of life in water-poor regions. Environmentally balanced wastewater treatment based on a duckweed and fish raising (pisciculture) ecosystem that provides economic opportunities for rural poor communities.
• Several technologies that convert waste from Sulabh Shauchalaya toilets into biogas for heating, cooking, and generating electricity.

Action Sociologist

A self-described “action-sociologist,” Dr. Pathak has worked on the leading edge of social enterprise for decades, combining business best practices and principled activism to advance the causes of better sanitation, societal change, and improved quality of life. In 1970, he founded the Sulabh International Social Service Organisation, an NGO that has been a catalyst for improved sanitation and social change across India. Now with more than 50,000 associate members who are rendering their voluntary services, the organisation has recently /started operations in Bhutan and Afghanistan. In collaboration with UN-HABITAT, Sulabh has trained engineers, architects, planners and administrators from 14 countries in Africa. Sulabh is now planning to start work in Ethiopia, Cambodia, Laos, Angola, Madagascar, Dominican Republic, Tajikistan and other countries.

Through Sulabh, Dr. Pathak has waged a decades-long campaign to abolish the traditional practice of manual “scavenging” of human waste from the simple pit latrines that have predominated across much of India. His early concern for the plight of the “untouchable” scavenger caste led to the development of the Sulabh Shauchalaya toilets to eliminate the need for scavenging in poor communities. Over the years he has led multiple initiatives to champion social dignity, economic justice, and liberation from the caste-oriented system for former “untouchable” scavengers and their families. Hygiene and Health Educator With the establishment of the Sulabh International Institute of Health and Hygiene (SIIHH), Dr. Pathak has led efforts across the NGO and government sectors to develop effective and culturally oriented hygiene and health models for urban slums and rural villages. In collaboration with other organizations, SIIHH has created hygiene curricula for young schoolchildren and their teachers, provided sanitation and health training for volunteer instructors in slums, and opened centres providing basic healthcare for urban poor at Sulabh community toilet complexes.

Working with the Indian Ministry of Environment and Forests, Dr. Pathak also established the Sulabh Environmental Information System Centre to gather and disseminate environmental information related to hygiene, sanitation, and sewage treatment for researchers, academics, policy makers, and students.
