Environment and Public Health Organisation

“A journey of a thousand miles begins with a single step” – Lao Tzu

Every short or long journey requires a first step. Environment and Public Health Organization (ENPHO) in its journey on Water, Sanitation and Hygiene (WASH), environment and public health took its first step on 4 November 1990. Envisioning to “Creating Eco-Societies” and touching the lives of millions with its services, ENPHO continued its steps to take initiatives and actions in the areas of environment and public health. Research, innovations and promotion of the WASH technologies and approaches have been a core priority of ENPHO.
Since its inception, ENPHO has succeeded in initiating at least one milestone each year. Starting from water quality monitoring of Bagmati River in 1990, ENPHO today has been able to establish itself as a pioneer in various areas of water, sanitation and hygiene. During its 25-year journey, it has completed more than 300 projects. It has footsteps in all 75 districts of Nepal through various programs. ENPHO has also reached out to various countries like Bhutan, Cambodia, India, Laos, Vietnam and Pakistan.
In 2015, ENPHO completed its 25-year journey benefitting more than 3.76 million people (2,142,698 on safe water; 493,410 on sanitation, 393,102 on integrated WASH and 308,357 on DRR and Emergency Response, and building capacity of 424,376 people on WASH).
ENPHO, a service-oriented, scientific, national non-governmental organization is constantly contributing towards sustainable community development by developing, demonstrating and disseminating eco-friendly technologies (eg. Rain Water Harvesting, EcoSan Toilets, DEWATS) and water treatment options (eg. Chlorine solution, SODIS, filters). ENPHO promotes integrated community based approaches for safe water, sustainable sanitation, solid waste management, hygienic behavior, improving indoor air, and environmental and air quality monitoring for creating healthy and environmental friendly societies.
ENPHO is governed by a General Assembly comprising of 108 members that elects an Executive Board once every three years. The Executive Director leads the 150 staff members of which 45% are female.
