UDDT versus Pour Flush (with vermi-composting) versus ???: which are sustainable sanitation technologies and systems for peri-urban areas in Africa? - by: hajo
To understand the following posting you must know that we already had an ‘off-line’ discussion about pros and cons and proper execution of vermi-composting. This discussion ignited EvM to emphasise (again ) her preference for UDDTs. She wants me to put my response on the forum for further discussion.

Dear Elisabeth,

I know you are fan of UDDT having even one in your villa in Germany. And I am sure it works well with people who know how to handle it and who can make use of dried faeces and urine in their garden!

But you may also know that the 100,000 UDDTs in eThekwini are not so well received/maintained by their users.

1. There is the feeling with people that they are denied development when any type of pit/bucket latrine (even if improved as UDDT or compost toilet) is recommended to them instead of sewers which all ‘developed’ people have;

2. (Therefore I try to make use of pour flush (which is considered a step of development) and connect it to a vermi-composting system);

3. For me UDDTs reach their limits when we want to install them in large numbers in peri-urban areas where people have 1) no space to make use of faeces and urine and 2) no interest to handle excreta by themselves;

4. At large numbers (possibly 10,000 to 20,000 in a town like Moshi) you have to introduce a collection service as part of the service chain;

5. And you also need large numbers to make the collection financially viable for the service provider and still affordable for the customer;

6. But at large numbers you really get a problem with the urine: 10,000 UDDTs, i.e. 40,000 users produce about 40-50m3 of urine every day which needs to be collected, transported, stored and reused, I doubt this can be done economically (unless you have huge flower farms next door which can make use of it);

7. So let us assume we can percolate the urine into the ground next to the toilets (as eThekwini does/did) and have only to collect the faeces;

8. Which amounts to 40,000 people x 0.3L/day = 12 m3/day whereby I assume that we use 50L containers which are filled/collected from a family of 4-5 at about monthly intervals;

9. At this service rate, I guess a ‘collection tariff’ can be worked out which is affordable for the customer and may be economical for the service provider for collection, transport, treatment and reuse especially if we can sell the product as soil conditioner/compost. This sustainability is one of the interesting aspects to be observed with Sanergy in Nairobi.

10. My concern is a bit, that we collect partially fresh excreta and the faeces are not yet treated at all when collected;

11. Therefore I see in pour flush with vermi-composting a number of advantages: 1) the desire of customers to have an ‘advanced’ flush toilet is partially fulfilled; 2) the ‘goose-neck’ of the pour-flush toilet prevents dumping of solid waste in the pit; 3) if successful the vermi-composter (pit or chamber) produces a compost which is hygienised, eventually even free of ascari eggs (if Dean is right) but definitely more pleasing to handle than the fresh faeces from UDDT containers; 4) pit or chamber needs to be emptied only every 2 to 5 years depending of use and success of the vermi-composting process.

12. I agree that the PFVCT (pour-flush cum vermi-composting toilet) is only that easy if we can percolate the black-water (or compost tea as Carl and Dean call it) into the underground without affecting the ground water. Otherwise we have a problem and need to collect the black-water. I would install a 2-3m3 underground tank from which black-water is collected at regular intervals and disposed of to the WTTP or treated for reuse if economical. With 4 people per toilet and 4L/flush, I expect an emptying interval of (4 x 4 x 2/d = 32 l/d à 3000 / 32 = 100 days) about 3 months. If all 40,000 users require that service, we have to collect 30 L/d x 10,000 = 300 m3/d but hopefully only 50% of customers need that service, still 25 trips for a 6m3 vacuum tanker per day.

13. You may be confused by all these ‘big’ numbers but I want to draw your attention to the fact that we are talking of serving XX,000 of people in one town, therefore we need efficient and working service chains and cannot depend on peoples’ willingness to empty and process their excreta by themselves.

14. Again: UDDT is a good concept but possibly more appropriate to improve sanitation in rural areas, maybe in rural villages, in my opinion definitely not in peri-urban areas of towns.

Looking forward to your comments !!

Am excited mhm stakeholders are starting to look at MHM wholistically, Am Eva from Kenya, I Having been dealing with sanitary waste disposal training,advisory and programs in Kenya for the last 8 years, mainly in institutions with over 800 hundred girls, there's need to offer environmental based solutions on matters of disposal, we have constructed over 38 two chamber demont Incinerator that attain over 800 degrees recommended minimum heat for incineration Globally the environment conservation is a key issue,has we offer solutions on disposal let us be keen to ensure that environmental policies and regulations are observed.]]>

Re: Sanitary Pad burner/incinierator design - by: SusannahClemence Menstrual hygiene management (MHM) Wed, 27 Jul 2016 23:00:00 +0000 Great set of short films on making WASH inclusive by Epic Arts in Cambodia with WaterAid - by: Louisa Gosling Epic Arts and WaterAid have produced some very short films to support the new national guidelines on making WASH inclusive in Cambodia.

A set of 1-3 minute animated films explain how to do accessibility and safety audits, barrier analyses, collect data on disability and how WASH organisations can work in partnership with Disabled Persons organisations. These are to support implementation of the national guidelines.

Another set of films - Count me in - is a series of short and entertaining sketches which really show the impact of non-inclusive WASH. Great for raising awareness in a light hearted way. None of the sketches are more than a few minutes long.

Finally there is a film that explains the process of working together to produce the films. this would be very useful for other WASH organisations wanting to do something similar in other countries.

This blog explains the process and provides links to the films.]]>

Re: SuSanA Capacity Development Working Group meeting at Stockholm WWW 2016, Tuesday 30 August from 14.00- 15.30h - by: Bertha
Quite impressed by the upcoming session and it is timely and relevant indeed,few comments though as a professional in the water sector:
What skills and knowledge will the water workforce of 2025 need?

clear definitions of the terms in the water sector for the non technical players to realize that water is a wide field and distinction need to be clarified i.e "water resources engineer" is a different field from "water resources persons" "environmental engineer" is different from " environmental science person" just like "public health (environmental) engineer" is different from "public health (environmental) person"
hence the need for the players in the sector to get the right persons for the correct task as when we talk of the skills and knowledge then where it's application matter for it to be relevant.

How do we attract people to work in the water sector and ensure they have the needed capacities to contribute to the future needs of the water sector?

kindly specify the divisions in the water sector, then from the divisions we can get the roles. on job training for students in colleges.

How do we develop/enhance the capacity of existing practitioners?

online learning for short courses is a good thing and such forums for learning exchange.

How do we engage and retain professionals who are working in the sector to contribute to the implementation of the SDG6?

Learning exchange forums.

with thanks,
B. N]]>

Thanks for your message.

The templates are in english. The "lorem ipsum" that you see is simply a filler text. So you will have to remove this and insert appropriate text under the various headings. Here is an example

Please let us know if you have any other questions.

Economic benefits from household-level access to WaSH - by: Lesley Many of us active on this forum understand that access to water and sanitation can have significant effects on household incomes: medical expenses can reduced by sustained good health, and productive time can be increased due to less sick days and less time required for water allocation as well as defecation. My paper, expanding upon the presentation I gave at last year's World Water Week in Stockholm, looks more closely at this topic and seeks to ignite deeper conversation and more data collection around these economic factors. Please read, share, and reply!
