Integrated Slum Upgrading: details and learnings from four experiences in Africa

Projects executed in Africa in the past few years have helped WSUP better understand the connection between water and sanitation issues and other challenges faced by residents of low-income urban areas. Our report “Integrated Slum Upgrading”, first released in May 2021, indicates a clear path towards successful outcomes: solutions to the most urgent problems in […]


Building resilience faster: Join us for World Water Week 2021

As the world faces multiple challenges from increasing urban populations to climate change and with the SDG deadline fast approaching, finding ways to improve the resilience of cities […]


New video shows how a citywide plan aims to tackle Malindi’s dirty secret: sanitation

Malindi, popular for its beautiful beaches and a celebrated tourist town, has a dirty secret. Three-quarters of the city’s 310,000 residents have no access to safely managed sanitation. Residents are forced to rely on illegal and unsafe pit-emptying services and the waste that is collected is then dumped at an unregulated municipal dumpsite or disposed […]


The residents of the coastal town of Malindi, popular for its beautiful beaches, largely depend on on-site sanitation. There is no waste treatment plant and only 25% of the waste is safely managed. As a result, 90% of hand dug wells are contaminated causing serious health risks in the communities.

Leaders in Kilifi County Government and the water and sanitation utility, Malindi Water and Sewerage Company (MAWASCO) have recognised the urgent need to improve the sanitation and solid waste challenges in the city and have created an ambitious plan to tackle this problem.

This summary report shares the vision for city-wide inclusive sanitation (CWIS) and the developed action and investment plans.

Can new pan-African policy guidelines help bring about national sanitation programmes?

With 72% of the 962 million people living in Sub-Saharan Africa lacking access to basic sanitation, and governments struggling to increase access, new action is required to accelerate progress towards Sustainable Development Goal (SDG) 6. This situation has been exacerbated by the Covid-19 pandemic, further underscoring the need for African governments to meet their national, […]


Marginalised urban communities are often characterised by three things: complexity, interdependence of challenges, and constant evolution.

The sheer numbers of people living close together in poorly planned communities can make improving the quality of life extremely difficult. The rapid rate of urbanisation – by 2050, the number of people living in African cities will double to 1.5 billion – means that there is no such thing as the status quo. Every month, every year, unplanned urban settlements get larger, and more complex.

In urban environments, issues such as water access, drainage, health, street design and solid waste management are all inextricably linked. Poor drainage leads to flooding, causing damage to flimsy sanitation facilities. Rubbish collected in drainage canals can exacerbate the issue and lead to stagnant water which becomes a breeding ground for disease. Sanitation facilities cannot be safely emptied if poor road access makes it impossible for emptying services to operate.

Tackling these issues in an integrated manner makes intuitive sense – but too often it just doesn’t happen, due to significant barriers such as cost, complexity, and the siloed nature of the development sector.

This report by Water & Sanitation for the Urban Poor (WSUP) and Arquitectura sin Fronteras (also known as ASF-España, referred to in the report as ASF-E), examines how to overcome this immense challenge, from the perspective of water and sanitation services.

The report demonstrates why water and sanitation improvements can be more effective when combined with other areas of urban development, and analyses how, in practice, this integration can occur.

Drawing on evidence from cities such as Maputo, Accra, Nairobi and Antananarivo, the report finds that integrating WASH with wider slum development can improve the overall impact, and the ease of delivery, of WASH services.

For urban sanitation systems to function safely, at scale, over time, and inclusively, they must be organized to support three functions: responsibilityaccountability, and resource planning and management.

This short publication looks at the function of resource planning and management, drawing on a desk review of over 40 urban sanitation investments in twenty-eight countries across Africa, Asia and Latin America.

For urban sanitation systems to function safely, at scale, over time, and inclusively, they must be organized to support three functions: responsibilityaccountability, and resource planning and management.

In this paper, we explore the accountability mechanisms that can be applied to the different service provision mandate structures identified in our parallel paper on responsibilities.

For urban sanitation systems to function safely, at scale, over time, and inclusively, they must be organized to support three functions: responsibilityaccountability, and resource planning and management.

This short publication looks at the function of responsibility: the extent to which sanitation authorities are clearly mandated.

Water-smart, inclusive, and integrated: ways to climate-proof sanitation systems

What have toilets got to do with climate change? This World Toilet Day, WSUP is highlighting how climate change is placing a growing strain on urban sanitation systems, and looks at ways to improve the climate resiliency of services to the poorest. Climate change is threatening sanitation systems in cities. Droughts in southern Africa have […]
