Today, on World Water Day, which this year is dedicated to wastewater, we’d like to seize the occasion to debunk some of the myths that prevent sector experts and city managers all over the world from implementing effective urban sanitation solutions:

Myth #1: People don’t demand improvements in sanitation where it is deficient or absent

In fact: There is latent demand for sanitation services even in the poorest areas.  What is sometimes true however is that low income residents often feel unable to affect change, especially when facing uninterested politicians, land tenure limitations, and technical challenges, and they are reluctant to openly express their demands.[1] 

Myth #2: Poor people are not willing to pay for sanitation services

In fact: Poor people are willing to pay for sanitation services, and they do, even when they receive sub-standard services.  Often, their only option is to resort to an unregulated private service to periodically empty their latrine/septic tank, whereas richer areas are connected to sewer systems with subsidized or free services.

Myth #3: There isn’t enough money to solve the urban sanitation problem

In fact: There are available resources but they need to be better allocated and used more efficiently. Investments needs are huge — 40% of estimated funds needed to extend universal access to safely managed water, sanitation and hygiene are needed for urban sanitation. In addition to increasing public budgets, which will be necessary but not sufficient, service providers and households need to be supported to make efficient investment decisions. Private financing can be leveraged for investment opportunities, especially if public funds are used more strategically.

Myth #4: Investing in urban sanitation is not productive

In fact: Sanitation investments provide demonstrated health, economic, social and environmental benefits that are essential to turn cities into vibrant economic centers. Globally, inadequate sanitation costs poor countries on average 5% of their GDP.[2] The economic return on sanitation spending is estimated at US$5.5 for every dollar invested. [3]

Myth #5: Centralized conventional sewers and wastewater treatment are the only way to solve the urban sanitation crisis

In fact: Experience of citywide inclusive sanitation in numerous cities (be it from Brasilia, Dakar, Durban, Manila, Kuala Lumpur or Seattle) mixing onsite collection and fecal sludge treatment solutions and sewerage solutions show important progress. Adaptive, expandable, decentralized and cost-effective approaches, mixing onsite collection and treatment and sewerage solutions, can be resilient to external economic, demographic and environmental shocks. Local innovation allows for sanitation solutions that reflect local conditions and meet customer needs.

Myth #6: Solving urban sanitation is all about toilets

In fact: Providing access to a toilet, a latrine or a sewer connection is only part of the solution.  The SDGs now require that human waste is conveyed, treated and reused/disposed of safely and sustainably. The full sanitation service chain needs to be sustainably managed.

Myth #7: Sanitation produces waste that is a nuisance to be eliminated

In fact: Human waste contains valuable nutrients. These can be recovered and reused as soil conditioner or fertilizer. Energy can be produced from both heat recovery and biogas combustion. Water can be recycled for industrial, agricultural and even potable use.  Such underutilized value, when monetized, can generate revenue to offset service costs.

In summary, there is no silver bullet; no simple, single solution to urban sanitation challenges. We must develop locally relevant and innovative solutions along the sanitation service chain that put customers first and focus as much on service management as on technology. City planners and other sector decision makers should consider the tradeoffs along the service chain between, for example, providing basic access to a toilet to all versus providing sewers and advanced wastewater treatment to the few.
Debunking these myths is part of our effort to help sanitation sector professionals in transforming their thinking and practices to deploy both old and new solutions in smarter ways to achieve sustainable, equitable and safe management of excreta for a whole city.
We’ll be issuing a Call to Action in April with a growing consortium of institutions to mobilize all stakeholders to radically shift their practices in order to achieve citywide inclusive sanitation.
Join us as we commit to this challenging yet critical goal!

There should be a world bank program wherein small informal settler communities can directly access assistance in debunking the seven myths about urban sanitation, including support facilitation for the actual implementation of ground actions that bring actual results in such communities. Where such accessibility issue should be online-based and simplified in the World bank Website with language option preferable to the language of the target poor beneficiaries.

I have been working on WASH projects since 2003 at grass root level. We need to create mass level awareness raising about the hazards to human health due to either improper or non availability for WASH facilities. For this we should create Community Resource Persons. They should move to the far off villages to carry the campaign. Low cost CLTS, sanitation system and household latrines be constructed.

Sometimes lone voices shout out their concern, but until it is a political issue, there is no clamor for glamour or glory in toilets. But even the President needs the same services as any other of his voting population. Safe water and sanitation go hand in hand with health and wealth of any countries economy.

I'm not sure where you are getting your information,
but good topic. I needs to spend some time learning much more or
understanding more. Thanks for magnificent information I was looking for this information for my mission.

Unquestionably consider that that you stated. Your favorite
justification seemed to be at the net the easiest factor to bear in mind of.
I say to you, I certainly get irked whilst
other folks consider worries that they plainly don't recognise about.
You managed to hit the nail upon the highest as well as
outlined out the whole thing without having side effect ,
other folks can take a signal. Will likely be again to get more.
Thank you

I attemted to reach out a few years ago to those I had contact info on but by and large toilets were met as a joke I am going to be better prepared this time and have a more definite message and better way to deliver it. Sanitation and clean water is not luxury, it is a necessity, not only for those directly affected but all of the society to prevent disease and give everyone a fair chance of advancing

Sanitation might include clean water management, waste management, livability environment management?? The myth is: why are the basic hygiene or cleanliness concept not applicable to some parts of the world?? a) The residents are not exposed to a cleaner way of living? b) The government officers are not exposed to a cleaner way of living? c) The area is too remote to get modernized?? d) all of the above.......
Eerrrr........ yeah, if we can debunk the myth, we might move ahead slightly sooner, or no??
