Sanitation

Improving faecal sludge management chains and on-site sanitation to better serve poor urban areas

In urban areas of low-income countries, improving sanitation faces big challenges in terms of technology, economics and partnerships. Given the complexity of managing excreta and waste water in densely populated neighbourhoods, where pit latrines remain the most widely used sanitation facility, innovation is required at each step of the chain faecal sludge management chain. Our work focusses on both hardware and social innovations to improve on-site sanitation.

We are committed to tackling the challenges related to on-site faecal sludge by working on three fronts:

Long-term programmes in Madagascar to develop and test innovative management models to improve the effectiveness and reach of sanitation services.
Development of technologies including desludging pumps, FSM tracking tools and faecal sludge treatment plants to ensure safe and affordable services.
Strategic advice  and technical assistance building on our practical experience. We work with city councils and the private sector to improve faecal sludge management in urban areas.

Technical Assistance

In Togo we are providing technical assistance, together with SEVES and ARWP to the municipality of Vo1 for the set up of a sustainable faecal sludge management chain. Our role is:

To support the definition and implementation of the global strategy and technical solutions.
To provide technical trainings to operators.
To support the set up of a treatment plant as well as the start of operations.
To follow up and control the construction work.

Project implementation

Since 2018, we have been working with the municipality of Fianarantsoa in Madagascar to implement a full FSM chain with a pro-poor focus thanks to funding from the Metropole Grand Lyon, SIAAP, AERMC and SAUR. We have worked on infrastructures, management and regulations together with the municipality and the private sector.

Our intervention continues until 2024 as we try to replicate successful infrastructures, further reinforce the capacities of the private operators managing the FSM services, and support the municipality in setting up the monitoring and evaluation processes.

Product development & Innovation

PuPu pump used in Madagascar to empty a pit latrine

We developed the PuPu pump as an alternative for unsafe manual emptying practices, and expensive vacuum trucks which cannot reach isolated areas with dense population.

The PuPu pump (which stands for Push and Pull) is a mobile pumping unit to empty pit latrines and discharge sludge safely for transport to the treatment plant. It can be operated and easily maintained by pit emptying businesses.

It is already used by various companies in Sub-Saharan Africa and South Asia. Read more about it here.
