Faecal Sludge Managment[FSM]

Faecal sludge management (FSM) is a management system to safely collect, transport and treat faecal sludge from pit latrines, septic tanks or other onsite sanitation facilities.

CDD Society’s Experiences

Why FSM?

Most cities and rural areas will not have underground sewers and treatment plants By 2021, 69% of India’s toilets will have septic tanks or pits ( on-site storage of faecal matter ) This faecal sludge will continue to be collected by “honeysucker” trucks and dumped unsafely in water bodies, open land and fields.

What is FSM?

FSM is a set of solutions that address the lack of training, regulation, and awareness of treatment options. A properly designed treatment plant safely treats faecal sludge for proper disposal.

How is FSM Implemented?

The municipality, existing desludging service providers and other stake holders are brought together to craft regulations, create sustainable operating models and participate in training, thus enabling the serivce providers to work under a legal frame work. A treatment plant is then implemented as a designated disposal point for the desludging operators where faecal sludge is treated and disposed off safely.

City Wide FSM
Our towns and cities need comprehensive FSM solutions
CDD has built India's first of its kind Faecal Sludge Treatment Plant in Devanahalli, Bangalore
We are also helping the Town Municipal Council implement complete FSM including reusing by-products



Services provided by CDD Society


Several technologies are applied to treat faecal sludge to reusable end products. We integrate solid waste with end products to create value added products for farming and cooking.


Awareness and behavioural change in all involved stakeholders in the Faecal sludge chain.

Policy / Regulations

Design FSM policy guidelines; develop frameworks and tools to aid decision making for implementation.

Business Models

Promote FSM as lucrative avenues for private sector participation. Further to this, development for improved service delivery in existing systems and incorporating best practices.


Propose structures and functioning of alternative/special cells to promote and spearhead FSM at state levels.
