Re: Interview Part 3 - by: secretariat
Part 3: About Jonathan’s opinions about the forum

What is making you write on the forum - what do you expect by making posts? How have you benefited yourself from using the forum?

I think the Forum is an excellent place for people to share their ideas and experiences and stimulate discussion. Some of the most beneficial discussions arise where someone contributes a posting in which they don’t necessarily have the answer fully worked out but they want to share their thinking on the topic and request feedback. This can result in a colleague responding that they are also trying to tackle a similar issue but their approach to dealing with it is a bit different. This mutual exchange helps both parties as well as the silent majority who are reading their discussion.

Do your colleagues or people in your network also use the forum?

Many of them do but many of them don’t. The main reason is that people don’t have time.

What don’t you like about the forum or about other forum users?

To be honest, I don’t think there is anything I don’t like about the forum or other users.

If you could change something about the forum, what would it be?

Sometimes I think it would be useful to have the option to be able click on a “Thumbs down” icon to show that you are not in agreement with what someone else is saying.

What is your advice to the forum moderators?

Forum moderators do a great role in overseeing discussions and helping to prompt people like me to respond to postings and, in my role as SuSanA Working Group 2 lead on Finance and Economics, to occasionally make a new posting.

Which topics or categories on the forum do you feel most passionate about?

Faecal sludge management, financing and economic and city sanitation planning.

Do you think we should try and include more non-English content on the Forum?

I don’t see any reason why not – although perhaps users should have the option not to receive postings if they are not in a language that they can understand.


Thanks a lot, Jonathan, for spending time on this interview when you are in the middle of a job change - it has been really interesting and great to get to know you a bit better.

Does anyone have any questions or comments for Jonathan? Have any of his posts or activities as Working Group 2 lead had an impact on you or changed your view on certain topics?

And what do other people think of Mughal's suggestion to rename the caption of "Featured User" to "Hall of Fame"? "SuSanA's Hall of Fame"? Or "Sanitation Hall of Fame"?

Re: NaWaTech Compendium of Technologies avaliable on SuSanA library - by: pkjha
I have just gone through the book particularly the chapters dealing with waste water treatment. It is collection of available technologies. It mentions technologies – ABR, Anaerobic filter, SBR, MBR, MMBR, biogas technology, and sludge drying beds- planted and unplanted and others. It lacks technical details of the technologies mentioned. Some chapters on water and waste water have been written by Ecosan Services Foundation with examples in India.
Under references, it mentions book on Compendium of technologies by EAWAG/ SANDEC. Regarding Sludge drying beds for septage management, information available in the book by EAWAG/ SANDAC is much more and practical than this book.
The book may be useful for those interested in the field. I could not find the cost of the book.
It took about 2 hrs to download the book.

Re: Do you know about wastewater disposal in deep wells in US? - by: canaday
The BBC Radio Discovery Program just published --Urine Trouble: What Is In Our Water?--

Some of the interviewees found significant effects of trace amounts of pharmaceuticals that come out in human urine, cannot get eliminated in wastewater treatment (WWT), and find their way into rivers. Other interviewees (who work in WWT) talk about how efficiently they get these chemical out of the water (and one of them said she likes the smell of WWT )

Re: Sanitation interventions during Ebola epidemic - by: joeturner
Tuladhar, Era, et al. "Residual viral and bacterial contamination of surfaces after cleaning and disinfection." Applied and environmental microbiology 78.21 (2012): 7769-7775.

Full text:


Environmental surfaces contaminated with pathogens can be sources of indirect transmission, and cleaning and disinfection are common interventions focused on reducing contamination levels. We determined the efficacy of cleaning and disinfection procedures for reducing contamination by noroviruses, rotavirus, poliovirus, parechovirus, adenovirus, influenza virus, Staphylococcus aureus, and Salmonella enterica from artificially contaminated stainless steel surfaces. After a single wipe with water, liquid soap, or 250-ppm free chlorine solution, the numbers of infective viruses and bacteria were reduced by 1 log10 for poliovirus and close to 4 log10 for influenza virus. There was no significant difference in residual contamination levels after wiping with water, liquid soap, or 250-ppm chlorine solution. When a single wipe with liquid soap was followed by a second wipe using 250- or 1,000-ppm chlorine, an extra 1- to 3-log10 reduction was achieved, and except for rotavirus and norovirus genogroup I, no significant additional effect of 1,000 ppm compared to 250 ppm was found. A reduced correlation between reduction in PCR units (PCRU) and reduction in infectious particles suggests that at least part of the reduction achieved in the second step is due to inactivation instead of removal alone. We used data on infectious doses and transfer efficiencies to estimate a target level to which the residual contamination should be reduced and found that a single wipe with liquid soap followed by a wipe with 250-ppm free chlorine solution was sufficient to reduce the residual contamination to below the target level for most of the pathogens tested.

Re: Sanitation interventions during Ebola epidemic - by: joeturner

The paper seems to make clear that wiping and the use of detergent is not enough to clean surfaces of the virus. The use of a bleach, preferably with surfaces wiped beforehand, seems to be the advice given in this paper to reduce risks.]]>

Re: Sanitation interventions during Ebola epidemic - by: arno Here is a paper on Noroviruses transferred via faeces on environmental surfaces. Drawing parallels with Filoviruses isn't really a long shot. Protecting against the highly contagious and persistent Noroviruses should provide the proper safety to protect against Ebola.

Effects of cleaning and disinfection in reducing the spread of Norovirus contamination via environmental surfaces by J. Barker, I.B. Vipond, S.F. Bloomfield.
Journal of Hospital Infection. Volume 58, Issue 1, September 2004, Pages 42–49

A reverse transcriptase polymerase chain reaction assay was used to study the transfer of Norovirus (NV) from contaminated faecal material via fingers and cloths to other hand-contact surfaces. The results showed that, where fingers come into contact with virus-contaminated material, NV is consistently transferred via the fingers to melamine surfaces and from there to other typical hand-contact surfaces, such as taps, door handles and telephone receivers. It was found that contaminated fingers could sequentially transfer virus to up to seven clean surfaces. The effectiveness of detergent– and disinfectant-based cleaning regimes typical of those that might be used to decontaminate faecally contaminated surfaces and reduce spread of NV was also compared. It was found that detergent-based cleaning with a cloth to produce a visibly clean surface consistently failed to eliminate NV contamination. Where there was faecal soiling, although a combined hypochlorite/detergent formulation at 5000 ppm of available chlorine produced a significant risk reduction, NV contamination could still be detected on up to 28% of surfaces. In order consistently to achieve good hygiene, it was necessary to wipe the surface clean using a cloth soaked in detergent before applying the combined hypochlorite/detergent. When detergent cleaning alone or combined hypochlorite/detergent treatment failed to eliminate NV contamination from the surface and the cleaning cloth was then used to wipe another surface, the virus was transferred to that surface and to the hands of the person handling the cloth. In contrast, were surfaces where contaminated with NV-infected faecal suspension diluted to 1 in 10 and 1 in 80, intended to simulate surfaces that have become contaminated after secondary transfer, treatment with a combined bleach/detergent formulation, without prior cleaning, was sufficient to decontaminate surfaces and prevent transfer.]]>

Re: Vortex bioreactors for the processing of contaminated wastewater (Plymouth Marine Laboratory, UK) - by: mikeallen
As our 12 month project draws to a close, I thought I'd update you on progress.

Firstly, we've published the first part of the work describing the alginate beads and their bactericidal activity.
You can check out the paper here:

There's another manuscript on the bioreactor itself currently undergoing revisions at Journal of Water Process Engineering.

There's a second manuscript under review at PLoSOne on comparing the bioreactor with UV.

And a third manuscript describing the results from our field trials is currently under review at Nature Science Communications.

In the end we managed to get our reactors to:
Chris Buckley's group in South Africa.
Andrew Whitesell's group at Cascade Designs in Seattle.
Bincy Baby at Eram Scientific in Kerala, India.
Christoph Platzer in South America.
And Ajeet Oak in Pune, India. We visited Ajeet's site for a week, earlier in the year to do our own field testing. It worked really well, we were all really happy with the performance of the system. The beads are letting us down a little, but we always knew they would need proper development in the future. The feedback on performance from partners has been really useful to us (Ajeet and Andrew's team are co-authors on the field work manuscript), and hopefully in the future we'll be able to go back to the partners with an updated and improved active agent.

That's all for now!

thanks for your note. Indeed the file is quite large, as the book includes many fotos, drawings and full graphic design. We are working on a revision, so we´ll try and have a lower resolution version in the comming months, which we will of course share with you.

The NaWaTech Compendium covers specifically the case of India, and includes specific chapters about the water situation in India, and examples of previous experiences in India in each technology factsheet. I invite you to have some patience downloading the file and check out the book, it would be really nice to hear your comments on the content.

As for our project website (, it´s currently down but our IT department is working on it and should be up again in the coming days. There you will find the Compendium (exaclty the same file) as well as many other reports, since our results are public, so please log in in a couple of days!

Re: Developing urine diversion systems in a developed world context - by: matsodoum01 Thanks for the document
Here in my Laboratory in Cameroon, we have already worked on struvite production.
The best information here is about struvite reactor which can be built with locally available materials and it low cost.
Carol McCreary wrote:

There are many ways to treat and reuse urine. Rich Earth Ostara's production of Crystal Green is a very high tech, commercial, proprietary option usually incorporated into large waste water treatment systems. Expensive.

For a lower tech solution see the STUN reactor used to produce struvite for fertilizer in Nepal.

And as Abraham notes, Rich Earth Institute is sanitizing urine for reuse in structured experiments through "storage or pasteurization". I hope he's say more about these basic procedures that we may be able to replicate in other communities.

All the best with your continuing investigations at Ecodomeo.
