Given what I hear of the difficult situation regarding logistics and skilled staff many organizations are facing in South Sudan, I think this is one of the few situations in which a fully pre-made and ready to deploy solution makes sense.

A while ago this very interesting solution was posted by a Norwegian company:
forum.susana.org/forum/categories/67-san...system-demonstration

But it would make sense to also look for other potential suppliers.]]>

nCircle R Usage at the Uttarkhand Flash Flood Relief Response - by: InnovationsUnlimited http://forum.susana.org/forum/categories/61-wg-8-emergencies/6503-ncircle-r-usage-at-the-uttarkhand-flash-flood-relief-response#6503 http://forum.susana.org/forum/categories/61-wg-8-emergencies/6503-ncircle-r-usage-at-the-uttarkhand-flash-flood-relief-response#6503
nCircle R - Innovations Unlimited's Quickly deployable Sanitation Superstructure was installed by RED R Engineers for creating Emergency Latrines. They found the product extremely useful due to it’s light weight and quick deployability. When used in conjunction with a pre-fabricated slab, it allowed them to install 15 Latrines in one day.

They found the product quite attractive and durable and this fact helped them to motivate the community members to contribute their labour and time to the construction process. Also, after a short demonstration, on how to install the unit, the community members were able to install it themselves. This product according to them is ideal for Emergency responses.

The toilets were installed under the ACC Cement's Uttarakhand Flash Flood Relief Response. Pfa some of the on-site pictures of the product installed.

Safe Sanitation Support for Typhoon Haiyan Survivors - by: Elmersayre http://forum.susana.org/forum/categories/61-wg-8-emergencies/6419-safe-sanitation-support-for-typhoon-haiyan-survivors#6419 http://forum.susana.org/forum/categories/61-wg-8-emergencies/6419-safe-sanitation-support-for-typhoon-haiyan-survivors#6419
The WAND Team is now gearing-up to support the survivors of the recent super-typhoon Haiyan that ravaged so many places here in the Philippines. Our support is in terms of providing safe sanitation via our ecosan toilets. We are veterans in this work having implemented the same during Typhoon Washi.

We are pre-fabricating the first toilet units to be installed in the area in our sanitation hub in Misamis Oriental since we anticipate great difficulty if we do this in the area. We will then use our 2 elf vehicles to transport the pre-fabricated units starting next week. One vehicle can load 20 pre-fabricated units. We will bring with us 6 expert carpenters and masons. They will constitute the core team. In the sites we will hire additional carpenters and helpers to team with each of our expert carpenters and masons. In addition to the builders, I will bring 3 expert trainers, veterans during Typhoon Sendong. They will train the local people who will eventually take care and manage the systems.

Once in the area, additional units will be pre-fabricated. We already have contacts in Ormoc and Tacloban Cities and they said we can use their places/backyards for the pre-fab activities.

I had a discussion with Rory Villaluna, the head of the National WASH Team directly handling sanitation work in Tacloban and Ormoc and all affected areas. They have people on the ground and they handle and manage all sanitation concerns. Rory is an old contact regarding sanitation work we are doing. We will directly work with them so there is no overlap.

We are marshalling all needed support. A good friend Robert Gensch has established a donation platform at,

www.betterplace.org/de/projects/15702-to...-auf-den-philippinen

Hoping for your kind response.

Very sincerely yours,

Elmer

Note from Moderator: Below an email received over the weekend from Elmer at WAND with a few additional images.
Dear Trevor and All Friends,

Warm greetings from the Philippines and thanks so much for the notice. Right now we are mobilizing our resources and asking people to help. Our global giving site is taking in so much donations already. Rob Gensch, a good friend cc'd here said he will do what he can via the German Toilet Organization. So is Jack Sim of the World Toilet Organization. We are now pre-fabricating the toilets, ecosan and pour-flush. Next week we will start constructing in the devastated sites.

not realy, the good and even mixing of fresh sewage and "old" sludge is importen HRT is short and SRT is long, therefore tank size smaller them other biogas tanks types.. good for fecal sludge treatment. easy transport on EURO-palettes and a fast & ready use is important. producing of energy for sanitation the sludge too.

But in general, I think a "passive" system like an ABR would have to be made much to large to accommodate for a sufficient retention time and the same time the huge number of users in a IDP camp for example. And capturing biogas isn't of much use in such a setting either.
At the beginning of my discoveries around ABR I had the same view!

Personally I think an relatively simple ATAD reactor should be the best solution for fecal sludge treatment in a camp setting.
I do not know about ATADs? I am not THE EXPERT for Bioggas up to now

I think it's pools you need to look at as example, not bouncing castles...

Yes, both is OK:

or


Alternative on a structure:


Both inflatable tanks and tanks on structures, without rough playing people 1.5-2m should be manageable in my educated guessing.]]>

Hi Detlef, I think it's pools you need to look at as example, not bouncing castles, you will fill the thing with liquid, not air.
I guess this could work for free-standing units, although if too high (eg. 1.5-2m) you have quite some pressure/weight to deal with. However, I guess free standing units will not work in many situations, as the inlet will usually need to be at ground level or below (if avoiding pumping). Now, as soon as you put your rubber ABR underground, you have to deal not only with pressure from water inside, but also with pressure from soil and water from outside, which makes it structurally more difficult (see the other discussion we had).]]>

Dear Colleagues and dear Mr. Spit,

Could this maybe a bit crazy idea of an inflatable "bouncy-castle" ABR possibly an input to WG8, as an "Open Source Idea" and a possible issue in the SUSANA forum too, to continuing discussion started by Mr. Jan Spit (# 2606) on the subject?

I would like to encourage other colleagues to bring in their "crazy" experiences/ideas too.

The GRP tanks of BORDA do not have to be buried, they functioning too above ground free-standing and even floating in flooded areas.


BORDA-ABR

Tanks made of GRP are relatively heavy. On-site repair and rebuild are possible without special equipment. A tank made out of PE is a bit lighter and more stable against damages. But on-site repair only possible with special welding equipment and know-how.

Both sturdy tanks have one disadvantage: If transported via plane or lorry many air have to be transported too.


"Crazy bouncy-castle idea" as "Open Source-Idea" for WG8:
Inflatable toys, pools, and "houses" with comparable geometry are already existing and in use under very rough condition.

Alternative proposal for possible transport on EURO pallets:
An inflatable double-walled square dimensional baffled tank, should be modeled based on the prefab tank of BORDA. Very flexible and robust temperature resistant textile material should be used to "produce" the necessary minimum of 4 units of baffled reactor chambers. Outside, on top and at bottom, a horizontally inflatable "sausage" should be placed and on each of 4 at the corners a vertical inflatable 'sausages' habe to be arranged.



by FH Flensburg

by AquaVerde

Somehow everything would look like a huge inflatable boat, but just a little more square. The necessary 8 inner walls (the baffles) of the 4 reactor chambers with its over-flows and under-flows could be made by walls filled with air. All this could been integrated into one big ABR-tank and can be brought by the mere inflation in place and function. Only one big sludge drain made of plastic at the first chamber could be enough. Alternative and maybe better providing to each chamber a separate sludge outlet. Via these 4 openings could also 4 separate heating pipes (25 mm PE 100 RC) put into the 4 reactor cambers connected to 4 heat exchangers made from sturdy PE too (e.g. pool equipment). The inflatable double exterior walls of ABR-tank would have an insulating impact by its own air cushion.

Gas storage: will be situated above the inflatable ABR-tank. An inflatable double-walled flexible gas storage above ABR made from plastic textile might look like a inflatable boat upside down. It is locked with the ABR.

Such an inflatable wwtp - biogas plant would be very sensitive to small bullets and knifes.

I hope I was somewhat understandable with this maybe crazy idea of an inflatable ABR?

Welcome to the forum! I am not sure if I understood your question correctly. Did I understand right that you are from Uganda, but are researching a topic in Bangladesh? (if so, why?)

Have you thought of UDDTs as a solution for flood prone areas in Bangladesh?
See e.g. this existing thread on the forum:
forum.susana.org/forum/categories/34-uri...nology-in-bangladesh

Also, I have moved your post into the category for working group 8 (emergency sanitation). If you look in this category, where you post is in now, you find a number of previous discussions on the same topic.
Also, you could put the keyword "flood" into the Search field in the top row (white text on black) - use the "advanced search". This brings up plenty of previous posts that dealt with the topic.

Maybe after reading those you could come back with more detailed questions or discussion points?

Bangladesh - Faecal sludge management in flood prone areas - by: Ahumuzaandrew http://forum.susana.org/forum/categories/61-wg-8-emergencies/5265-bangladesh-faecal-sludge-management-in-flood-prone-areas#5265 http://forum.susana.org/forum/categories/61-wg-8-emergencies/5265-bangladesh-faecal-sludge-management-in-flood-prone-areas#5265 I am interested in sanitation systems in areas mostly hit by disasters. My concern in this matter is Bangladesh and its floods. Annually, this disaster has always left many people in the low land areas of Bangladesh at great risk of diseases and others dead. For a couple of yeas, many potential Organizations have intervened in studies to come up with solutions, others have been on the ground to put up new sanitation technologies to reduce on the impacts of floods to the communities. For known and or unknown reasons, from the literature I have come across, most solutions have always been challenged by the disaster magnitude. The most important aspect in this regard is "FAECAL SLUDGE MANAGEMENT". It is a wide aspect that I may call it a "SANITATION UMBRELLA". Some times I Imagine, if most of the cheap, sustainable and reliable systems have kept failing not because they are poorly designed but the magnitude of the disaster keeps challenging, then finally relocation of the population affected would be the solution as the Government with the help of Non Government Organizations plan on how to use such areas for other development such as Industrial Parks. However, this also depends on the political status of the country. Otherwise I think the solution for fecal sludge management will seize form being cheap and sustainable to expensive and sophisticated solutions. Very soon am required to have a study on the same issue "FAECAL SLUDGE MANAGEMENT IN FLOOD PRONE AREAS", but am still wondering which new technology I will recommend at my level that may contribute towards the solutions to this problem!! For the Organizations that have interacted with the Government Authorities of Bangladesh, what is the Government's thinking/plan for a permanent solution to its people??]]> WG 8 (emergencies) Sun, 11 Aug 2013 09:54:02 +0000
