CDD Society is a not for profit organisation formally registered in 2005 to promote decentralised sanitation solutions across the country. To make more of an impact, we work with a network of like-minded partners. We are the primary implementation partner of BORDA-South Asia, in India.

Our Approach

At CDD we believe that decentralizing sanitation interventions, with emphasis on leveraging existing infrastructure, is the way to go. With exploding populations urban infrastructures are severely challenged. Vertical growth maxes out capacity and horizontal growth results in unserved areas. Decentralized sanitation options complement existing solutions, enable fast implementation, and require low investments thus preventing pollution

Our Work

Our team provides solutions across the spectrum – from treating the wastewater of communities, to remediation plans for drains and lakes, to sanitation plans for cities. In order to multiply our impact we dedicate considerable resources to training stakeholders - skilled operators, professional practitioners, municipal engineers, and decision makers. Through these collective efforts we constantly work towards 100% sanitation for all.


Our Mission


What happens after the flush?

Where does it all go? Is it going into a sewer system, is it being treated or is it being dumped into the environment? With a growing number of people moving to India’s cities and with expansion becoming unmanageable, the answers to these questions become critical to understand how we can work towards a healthy environment.


Release of untreated liquid and solid waste pollutants to the immediate surroundings of a community directly threatens the life and wellbeing of the entire ecosystem - humans, animals, and plants. CDD Society’s mission is to provide robust and sustainable post-toilet infrastructure with the aim of improving health and hygiene, preserving the environment and securing water resources.
