Problem Addressed

CDD Society aims to combat the pollution of surface water and contribute to the reduction of ground water contamination through wastewater treatment. In this way, they aim to improve health, access to proper sanitation and human dignity for people in urban slum areas. CDD also aims to address the missing link in sanitation: wastewater treatment. The policy environment in India is currently focused on building toilets, while largely neglecting wastewater treatment, which only shifts the problem from one location to another. Only 300 out of 5,161 urban areas have partial sewer systems that are mostly connected to centralized treatment plants where less than 15% of total sewage is treated.

Centralized treatment has not worked well in India because it is expensive to build and maintain, and requires large sewage systems, electricity, and skilled labor. In addition, they are prone to disruptions due to road repair, civil works and natural disasters. Over 25% of capacity is not utilized due to breakdowns and high costs. These problems are compounded by the fact that decentralized wastewater treatment, when designed inappropriately, is also unreliable. In urban locations, 35% of people are connected to unscientifically designed decentralized septic tanks which result in unusable toilets and ground water contamination.

Innovative Approach

CDD Society has been able to create an alternative to expensive and unwieldy centralized sanitation solutions that have been proven unworkable in the Indian context. The organization’s innovative technology is a decentralized basic needs service, which is simple and modular and can be easily adopted to local conditions. The organization has also applied this innovation at scale by participating in City Sanitation Planning. City Sanitation Planning is a methodology and planning tool to carry out citywide sanitation planning with decentralized basic needs services in small and medium towns.

Program Solution

The project has several facets. The first is the improvement of wastewater and solid waste management services and sanitary infrastructure in areas with high density of population. This will be accomplished through city sanitation planning, capacity building and lobbying with the relevant stakeholders.

Then, the implementation of DEWATS can be expanded to a larger scale with additional third party funds. Strengthening the sustainable operations of the project partners is also essential. The program is based on the creation of appropriate, demand-based, de-centralized service structures in the fields of community based sanitation (CBS). In particular, de-centralized management of wastewater (DEWATS) and solid waste (DESWM), as well as de-centralized water and energy supply (DEWAS), are imperative to meet the basic requirements of the under-privileged sections of society in selected regions.

Slum dwellers are organized into self-help organizations that have access to and benefit from sanitation infrastructure with the added benefit of an environment-friendly DEWATS technology, thus contributing to the improvement of living conditions in the project areas.
