The History of Sanitary Sewers says
"Over the past twenty years, Jon Schladweiler, the Historian of the AZ Water Association, has researched and collected materials related to the history of sewage conveyance systems. Many of these have been displayed in a traveling exhibit entitled “The Sewer History Exhibit” The overall collection of sewer history materials covers the era from approximately 3500 BCE through the 1930s CE. The purpose of this website is to house this dynamic collection of materials about the evolutionary development of sewers over the past 5500 years, and to provide a location for the sharing and distribution of information to others. The donation of additional photos, sketches, articles, books, or other sources of historical information on the history of sewers is appreciated. This website is an educational, non-profit endeavor. Its intent is to offer some insight into the history of sewers and the role its operators, engineers, and builders have played in making our environment, homes and communities better and healthier places to live.
All members are requested to have a look on this interesting web link and learn the historical evolution's Global sewer and sanitation ]]>

Death in Manhole - by: F H Mughal Death in Manhole

According to the news of 18 January 2017, 3 persons died in the manhole in Key Largo, Florida (

The manhole was filled with hydrogen sulfide and methane gas created from years of rotted vegetation. The manhole was 15 ft deep, and its diameter was just enough to fit a body. The workers, who were not of the utility department (they were outsourced workers), probably, had no training and, they went inside without safety measures.

According to US Occupational Safety and Health Administration (OSHA), While moderate concentrations of hydrogen sulfide can cause more severe eye and respiratory irritation (including coughing, difficulty breathing, accumulation of fluid in the lungs), headache, dizziness, nausea, vomiting, staggering and excitability, high concentrations can cause shock, convulsions, inability to breathe, extremely rapid unconsciousness, coma and death. Effects can occur within a few breaths, and possibly a single breath.

While these accidents are common in poor developing countries, it is a bit surprising that the incident occurred in a developed country.

It is essential that the sanitary workers are taught about the safety measures, before they descend in manholes.

Re: Other Sanitation Networks - Complete the List with yours - by: muench
Thanks for starting this list. Could you please clarify a bit more what you meant with
We've started to compile a list of sister networks in order to solidify collaboration in the near future.

What are sister networks?

How did you choose the ones that are currently on your list? E.g. in which way would be a sister network? Isn't that only a blog?

And what is the "list of resources" that you started?

If I go to the SuSanA website and click on partner and then filter by Type: network/association I get these 28:

Is that also how you generated the list above?

What order is your list in? Perhaps convert it into alphabetical order so that it's easier to see which one is missing.

E.g. I am missing these two Dgroups:

Are you differentiating between organizations and tools?
E.g. WSSCC would be the organization but the LinkedIn Group "WSSCC‘s Community of Practice on Sanitation and Hygiene in Developing Countries" would be the tool (

How are you planning to priortise the entries in this list in future?

Re: Interest in Sanitation – November 2016 Sanitation Updates - Views by Country - by: muench United States come from people working for organization doing work on sanitation in developing countries. For example Unicef, WSP, WaterAid America, World Vision and the many universities and organizations in the US who have grants from the Gates Foundation.

If you look at SuSanA's membership database you have the same two countries at the front: India and the US.

Both countries also have a high total population; you could convert the numbers into % viewers from that country, and a different picture may emerge (e.g. small countries like Netherlands or Switzerland might well have a higher figure based on % of total population).

Another thing you should keep in mind is that Sanitation Updates is only available in English. Perhaps having it in other languages would lead to more readership in some countries, e.g. having it in French for the francophone African countries might be interesting.

Interest in Sanitation – November 2016 Sanitation Updates - Views by Country - by: F H Mughal Interest in Sanitation – November 2016 Sanitation Updates - Views by Country

My good friend, Dan Campbell, Knowledge Creation/WASH Specialist, USAID Water Communications and Knowledge Management (CKM) Project, has shared with me, among others, extremely useful and interesting information.

The information pertains to the viewing of Nov 2016 Sanitation Updates by country. The list is attached. The list shows interest in sanitation by viewers from various countries.

The list shows that 5,627 viewers from India visited the Sanitation Updates page. This is understandable, as sanitation is a major problem in India, and India is a populous country. This is indicative of peoples’ eagerness to seek knowledge in sanitation, and solve sanitation problems in India.

Very surprisingly, the next country in the list, with highest viewers, is none other than United States, with 3,822 views. Sanitation is not a problem in a rich and developed country like United States. This leads to the question: Why so many viewers from United States? This constitute, so to say: “Believe it or Not!” I would welcome comments, especially from people living in United States, on why so many viewers from United States are interested in sanitation.

UK had 814 views. Although, there are little sanitation problems in UK, the number of viewers indicate concern of people for sanitation, though the viewers are nearly one-fourth the US viewers.

Viewers from other countries are: Philippines 532; Kenya 339; Bangladesh 277; South Africa 276; Australia 260; and Nepal 233. Though sanitation is a problem in Bangladesh, the number of viewers are relatively low. Australian viewers seem significant, considering the status of sanitation in that country.

Pakistan had 146 viewers. This shows lack of interest in sanitation, despite the fact that we have major problems of sanitation.

I’m sure, the Susana community will find the list interesting.

“Don’t focus on smart cities. We need to grow into a smart society.” - by: AquaVerde Thomas Rau: “Don’t focus on smart cities. We need to grow into a smart society.”
What is your view on smart cities?

I think the question is irrelevant. We shouldn’t be asking ourselves how we could live in a city by making it smart and sustainable. We have to ask ourselves if we should want to live in cities at all. I often wonder why it is that so many people chose to live in such a crowded space. Isn’t it time to re-evaluate? It’s all a matter of choices, and we have to chose smart. By focusing on making cities smart, we make it an objective instead of a means. It’s a way of continuing the past, while we should transform the future.

Skeletal Fluorosis, What aggravates it and what makes fluoride in the water that you drink to go crazy in your body and lead to bone deformity? - by: VikasR Note by moderator: The following is a copy from this blog post:


What makes fluoride play around in your body and aggravate? Does a standardized, universal bench mark of 1.5 ppm of fluoride per liter in water hold good? are there other reasons that need to be factored in?

Questions in your mind, yes?

Ok, lets start things off; The reason for Fluorosis is High levels of fluoride in drinking water supplies and in food grown in endemic areas. the more fluoride there is in the water and food you consume the more severe is your fluorosis, as simple as that.

But interestingly; although there is a standard defined by the World Health Organisation (WHO), which has come up with a universally accepted theory that any fluoride in water upto 1.5 ppm per day per liter is safe to have, The truth is that there cannot be a fixed rule that applies randomly to all. The body mass, the body built, your being a child or adult and other factors have a huge role in determining how much of an effect fluoride can have on you if you happen to be in a endemic area.

Also; in a fluoride affected area, Tropical or extreme hot weather and some hard manual labor can make you feel thirstier, so your body’s water requirement grows and you’d be drinking more water. A lot more fluoride, therefore, which is beyond what’s reasonable; no matter what the limit therefore enters your body.

If your nutrition is poor; which in “fluorosis avoiding terms” essentially means that your food is deficient in reasonable calcium, magnesium and vitamin C which gives you the wherewithal in countering fluorosis by making fluoride flush out; you could end up having really bad skeletal fluorosis, if you keep drinking contaminated water.

Magnesium has a peculiar relationship with fluoride and its optimum intake helps in elimination of fluoride from the body. Vitamin C as well is beneficial in some way in reducing fluoride toxicity.

Fluorosis which earlier used to take much more time to manifest itself in people and very rarely in children, has for the past decade or so started showing up much quicker now. even in small children who are showing symptoms, which was never before the case.

The deterioration in food habits,i.e. foods people that now have being low in nutritional value, is what is leading these things to happen.

A Renal or kidney disease can also aggravate your fluorosis by increased deposition of fluoride in the bones. A diseased kidney cannot handle fluoride excretion from the body, and hence you’d find an increased deposition taking place in bones.

After all; where else can the excess fluoride go if it is unable to find it’s way out of the body?

to sum it up briefly; its about you taking the right kind of food and the capacity it gives you to flush toxins such as fluoride out of your body, along with switching to safe water]]>
