Q & A
What is Citywide Inclusive Sanitation (CWIS)?
-CWIS is an approach to urban sanitation where all members of a city have equitable access to improved sanitation services, both sewered and non-sewered, with no environmental contamination along the sanitation value chain. It emphasizes context-appropriate solutions and a service-based model rather than a traditional infrastructure-focused approach.
What are some of the key challenges in global sanitation mentioned in the script?
-Key challenges in global sanitation include inequity, focus on toilets only, inappropriate technologies, inadequate planning, poor policies and regulations, and a lack of financial and human capacity. These issues are particularly prevalent in cities in the Global South.
How does CWIS differ from conventional sanitation approaches?
-CWIS moves away from the conventional infrastructure-focused, sewers-only model to a more holistic, service-based approach. It recognizes the need for a mix of sanitation solutions (both sewered and non-sewered) based on local contexts, aiming for equitable, sustainable, and environmentally safe outcomes.
What role does equity play in the CWIS approach?
-Equity is central to CWIS. It ensures that vulnerable communities—those marginalized by gender, geography, socioeconomic status, and other factors—are not left behind. It focuses on providing equal access to sanitation services in terms of availability, accessibility, affordability, and acceptability.
What are the Manila Principles in relation to CWIS?
-The Manila Principles, launched in 2019, lay out the framework for CWIS. They focus on equitable sanitation services, environmental sustainability, a mix of technologies, comprehensive planning, monitoring and accountability, and diverse business models. These principles guide the implementation of CWIS projects worldwide.
Why is a 'mix of technologies' important in CWIS?
-A mix of technologies is important because sanitation solutions need to be tailored to local contexts, such as population density, water availability, financial constraints, and sociocultural factors. Different areas in a city may require different sanitation systems, like centralized or decentralized models, to meet their specific needs.
How does CWIS incorporate environmental and public health concerns?
-CWIS ensures that the entire sanitation service chain—from toilets to containment, transport, treatment, and end-use—is managed to prevent environmental contamination and protect public health. It addresses not only access to sanitation but also pollution management, linking to SDGs 6.2 and 6.3.
What are the benefits of integrating private sector involvement in CWIS?
-Involving the private sector through models like public-private partnerships (PPPs) and build-operate-transfer (BOT) schemes brings in additional resources and innovation. This helps in delivering sanitation services in resource-constrained settings, fostering a sanitation economy and ensuring long-term sustainability.
Why is comprehensive planning essential in the CWIS approach?
-Comprehensive planning is crucial in CWIS because urban sanitation is complex and requires addressing multiple interrelated aspects. It ensures long-term sustainability by involving both top-down technical planning and bottom-up community engagement, as well as integrating other services like water supply and solid waste management.
How does CWIS promote accountability and sustainability in sanitation services?
-CWIS emphasizes monitoring and accountability by setting clear targets, tracking sanitation system performance, and ensuring proper operation and maintenance. It advocates for institutional frameworks with accountability mechanisms and dedicated funds to sustain long-term sanitation services.

🚽 Tackling Global Sanitation Challenges
Sanitation is a complex issue that has been the focus of international development agendas since the late 60s. Despite efforts, nearly half the global population struggles with safely managed sanitation. Abishek Narayan, a researcher at Sandec, highlights the widespread issue of sanitation poverty in cities across the Global South, with examples like hanging toilets in Dhaka and flying toilets in Nairobi. The root causes are varied, including inequity, inadequate planning, and poor policies. The solution to this issue lies in a holistic approach, and this is where Citywide Inclusive Sanitation (CWIS) comes into play. CWIS aims to address these diverse challenges by implementing a mix of sanitation solutions that focus on equity, inclusivity, and environmental sustainability. The concept was formalized in 2016, with a billion-dollar commitment following in 2018 and the Manila Principles on CWIS launched in 2019.
🌍 Holistic Urban Sanitation through CWIS
CWIS is an approach that ensures equitable access to adequate and affordable sanitation services for all city residents, using a mix of technologies—both sewered and non-sewered—without polluting the environment. It moves away from a sewer-centric infrastructure model to a service-based approach, tailored to the specific needs of different communities. CWIS takes into account the entire sanitation chain, from toilet access to waste treatment and resource recovery. The CWIS approach is designed to help meet the Sustainable Development Goals (SDGs), particularly those focused on universal sanitation access and reducing pollution (SDG 6.2 and SDG 6.3). This paragraph also outlines the need for equity, planning across the entire city, and ensuring that sanitation services cater to all populations, including vulnerable groups.
💧 Environmental and Public Health through CWIS
The second paragraph stresses that sanitation doesn't end with access to toilets—it requires comprehensive management throughout the entire sanitation chain. Poor sanitation practices lead to public and environmental health risks, with untreated waste contaminating the environment. Addressing sanitation must involve both SDG 6.2 (access to sanitation) and SDG 6.3 (pollution control). Additionally, the text emphasizes that sanitation technologies must be context-specific, considering local factors such as population density and water availability. CWIS promotes a shift towards circular sanitation models, where waste is treated as a resource, enhancing sustainability and creating new revenue streams.
📋 Comprehensive Planning and Monitoring
The paragraph highlights the importance of comprehensive and long-term planning for urban sanitation, beyond immediate fixes. CWIS expands sanitation planning to include related areas like water supply, solid waste management, and stormwater drainage. To ensure sustainable sanitation services, cities must bridge top-down planning with bottom-up community involvement. Monitoring and accountability are key, with clear targets, performance tracking, and ring-fenced funding essential for long-term success. The role of institutions in maintaining sanitation services is critical, as is the involvement of private entities to support and innovate within resource-constrained settings.
📊 Diverse Business Models for Sanitation
This section outlines the importance of blending different business models to achieve effective sanitation services. While governments are responsible for public sanitation, partnerships with the private sector can help overcome resource and capacity constraints. Various models, such as public-private partnerships (PPPs) and build-operate-transfer (BOT) arrangements, are beneficial for both parties. Innovative financing mechanisms and resource recovery incentives can make sanitation more affordable, allowing diverse solutions like container-based or community-managed toilets to serve informal urban settlements. CWIS offers a holistic approach to urban sanitation, aiming to make services equitable, sustainable, and adaptable to local needs.
🍾 CWIS: Old Wine in a New Bottle?
While CWIS might seem like a repackaged version of long-standing sanitation principles, it offers the comprehensive, multi-faceted approach necessary for today's urban sanitation challenges. It addresses multiple leaks in the sanitation agenda, promoting holistic solutions for cities. If you want to dive deeper into CWIS, several key publications are available on the Sandec website for further reading.

Transcripts
Sanitation: It is complex.
Since the late 60s there have been multiple international development agendas towards providing adequate sanitation.
Despite these efforts, close to half the world is still struggling
with achieving safely managed sanitation.
My name is Abishek Narayan and I'm a researcher at Sandec.
Cities across the global south face this common challenge of sanitation poverty.
Whether it is the hanging toilets in Dhaka or the flying toilets in Nairobi.
However, the problems causing poor sanitation are often different.
They may be one or a combination of the following:
Inequity, focus on toilets only, inappropriate technologies,
inadequate planning, poor policies and regulation, lack of financial and human capacity.
So if the problems are so complex and diverse, how could the solutions be so simple and narrow?
We need a holistic approach that can tackle the complexity of these issues.
That is, simultaneously plugging these different leaks.
And that's what citywide inclusive sanitation or CWIS is all about.
In this video, we will describe the emergence and uptake of city-wide inclusive sanitation,
explain the CWIS approach, break down the Manila principles on CWIS.
CWIS was conceived in a conference on urban sanitation in 2016
by a few experts who were convinced that business as usual was not working.
In 2017 a call to action was released and was followed by a billion-dollar commitment
for the cause in 2018. In 2019 the Manila principles on CWIS was launched, and in
2020 academic literature on CWIS started being published. In 2021, we can see a number
of pilot and mainstream projects on CWIS being commissioned and implemented all across the world.
CWIS is defined as an approach to urban sanitation, where all members of the city
have equitable access to adequate and affordable improved sanitation services
through appropriate systems of all scales, both sewered and non-sewered technologies.
And all this without any contamination to the environment along the entire sanitation value chain.
CWIS as an approach is simply a move away from conventional infrastructure-focused, sewers-only approach to a
more service-based, context-appropriate approach with a mix of different sanitation solutions.
Just like how plugging one or two of these holes the water leak cannot be stopped,
we need to simultaneously address the multiple different aspects of urban sanitation in order to
truly make progress in achieving the SDGs on universal access to safely managed sanitation.
Now let us look at how the CWIS approach does all this by breaking down
the CWIS concept into more easily understandable principles.
Firstly, equity.
Sanitation needs to be equitable, which means no one is left behind.
But often, the vulnerable communities, those discriminated by gender,
age, geography, socioeconomic reasons, religion, caste, etc.
are not adequately considered when planning and implementing sanitation solutions.
Equity does not only mean that everyone is given an equal level of infrastructure, rather it means
that they are given an equal access to service in terms of availability, accessibility, affordability, and acceptability.
Sanitation needs to be planned for the whole city. Not just in households, but also
in schools, healthcare facilities, commercial and public spaces that cater to the needs of
not just residents, but also visitors and migrant workers.
Secondly, Environmental and Public Health.
Sanitation does not end at the toilet, it merely begins there. The whole sanitation service chain
of toilet, containment, emptying, transport, treatment, and end use needs to be well planned.
If we only look at latrine access, then we are just displacing the problem,
not managing it. This puts both public health and environmental health at risk.
Sanitation and environmental health are closely linked. Take a look at this recent study which
shows the different pathways through which faecal contamination can end up in the environment.
Therefore, we need to address not just SDG 6.2 on access, but also SDG 6.3 on managing pollution.
Thirdly, Mix of Technologies.
There are multiple factors that determine the appropriateness of sanitation technologies.
For example, population density, sociocultural behavior, water availability, financial and spatial constraints.
When these factors vary according to the local needs,
why should sanitation solutions be the same? Even within the same city, different neighborhoods
can have different types and scales of technologies. For example, in the same city, centralized
decentralized, on-site, container-based sanitation, among others can co-exist.
But this combination has to be carefully implemented according to the contextual needs.
Further, we need to move away from a waste creation model
to a resource recovery model. And in this way we can increase the circularity
of the sanitation service chain, and create additional revenue streams.
Next, we have Comprehensive Planning.
CWIS has laid bare the complexities of urban sanitation.
With more explicit targets, we need more comprehensive planning.
CWIS does not just look at short-term answers, but has plans for the long-term keeping future scenarios in mind.
CWIS does not just focus on the silo of sanitation in cities, but expands to
environmental sanitation that includes other areas such as water supply, solid waste management,
stormwater drainage, among others. This way, many core benefits from these synergies could be gained.
But for all this, we need to bridge top-down and bottom-up planning approaches. One that involves
the communities as much as it involves the technocrats who design the technical solutions.
Next, we have Monitoring and Accountability.
There's a quote that says if you cannot measure it, you cannot improve it.
Monitoring ensures that the performance of sanitation systems and services are tracked,
the operation and maintenance are carried out for long-term sustainability.
The capacities of sanitation service providers and regulators are essential for this.
Authorities need to keep clear targets, ring-fenced funds for sanitation-related activities.
All this requires institutional arrangements that have clear accountability mechanisms in place.
Finally, Mix of Business Models.
While sanitation is clearly a public service mandate and the governments and institutions are in charge,
support from the private sector is extremely valuable in resource and capacity constraint settings.
Various service and business models such as private-public partnerships, or build-operate
transfer models (BOT) already exist. Such models are beneficial to both parties, and allow for
a sanitation economy to emerge which also allows for more innovations to take place in the sector.
This helps the needs of various people to be met through various modalities of service.
For example, a community which is present in an urban informal settlement could be served
by container-based sanitation or community managed toilets.
Innovative financing mechanisms and resource recovery incentives can help maintain the affordability in service delivery.
In summary, CWIS is a holistic approach that has gained traction in the last few years
and is possibly the future direction of urban sanitation.
It is best understood through the Manila Principles on CWIS.
There are slightly different versions of the CWIS approach and its principles,
but they all come down to the basics of making urban sanitation sustainable and equitable.
You might have also noted that most of these principles of CWIS have always been around in the development agenda.
But it is the first time that the sector has come together with such a holistic and unified vision.
Therefore even though CWIS might seem like old wine in a new bottle, it is exactly what we need today.
A way of plugging all six of these leaks in the urban sanitation agenda.
If you would like to understand more about CWIS, and understand it in greater depth,
here are three key publications that you can find in the Sandec website.
