thank you so much for your kind response and I am very sorry for taking so long with answering your questions.
Here we go.....
First how long has the system been in operation, and how many people in the town does it employ?
The plant is in operation since April 2013. The waste water treatment plant is designed for 1500 people. Currently roughly 700 users are using the services. As the system is under monitoring these are preliminary numbers, e.g. not all individual houses are yet connected to the system and not all cluster washhouse households applied yet for a key.

What has the community's experience been with the vacuum system, and have there been any significant or unexpected operational or maintenance challenges with either the sewer or treatment system itself?
Since beginning of operation no severe incident has been reported. Until now, there has been only one blockage caused by vandalism at a vacuum chamber. The washhouse suffers smaller damages at the shower and toilet cistern handles. The users have been trained in advance on the system, on how to use and maintain the facilities within the programme of community health clubs (CHC).

If the project were to be replicated elsewhere, how much would you estimate that the entire system would cost per capita? And how much longer is this project funded for?

Expenses for investment and operation are subject to ongoing economic evaluation.
The local operators can operate and maintain the plant without much assistance even without external service provider. It is the result of continuous involvement during construction and commissioning as well as intensive training in the initial phase of operation.
From our experience we like to highlight the need of Intensive supervision during the construction phase. Furthermore, it was very crucial to learn from the experiences in other towns that were using the vacuum system.

Please do not hesitate to contact me if you like to have further information. We are still in a learning process and I am appreciating any comments.

Best regards

As part of a doctorate project at Unversity College London, which is closely alligned to the SPLASH funded research led by IWA entitled Sustainable and resilient sanitation service chains in Maputo province, Mozambique, a rapid participatory risk assessment tool for urban sanitation systems is being developed

The tool asks communities to assess the level of risk in their neighborhood according to a risk framework and indicators of risk. You will see (Introduction page in the attachment) that there are 5 different categories of risk indicator that form the basis of this questionnaire.

However, it is apparent that in actual terms, the indicators contribute to the overall level of risk in varying amounts. The purpose of this questionnaire is therefore to ask you to help define the weighting to be assigned to the indicators according to the perceived level of importance that each indicator plays in the transmission and resultant incidence of disease.
 
We would be very grateful if you could fill in the questionnaire, which contains 4 worksheets (woksheets 4.1-4.4). On each sheet, a number of factors contributing to risk are paired. For each of these pairs, please indicate which you think has a higher risk to human health, and by how much relative to the other factor.

Please email me back the questionnaire.

Thanks a lot.

As part of my PhD studies at Unversity College London, which are closely alligned to the SPLASH funded research led by IWA entitled Sustainable and resilient sanitation service chains in Maputo province, Mozambique, I am developing a rapid participatory risk assessment tool for urban sanitation systems.

The tool asks communities to assess the level of risk in their neighborhood according to the following risk framework and indicators of risk. There are 5 different categories of risk indicator that form the basis of this questionnaire: primary sanitation systems, secondary sanitation systems, proximity to the hazard, transmission pathways and vulnerability.

The indicators contribute to the overall level of risk in varying amounts. There is limited data on this subject and therefore I am ask you to help define the weighting to be assigned to the indicators according to the perceived level of importance that each indicator plays in the transmission and resultant incidence of disease.
 
I would be very grateful if you could fill in the questionnaire, It should only take five minutes. It contains 4 worksheets. On each sheet, a number of factors contributing to risk are paired. For each of these pairs, please indicate which you think has a higher risk to human health, and by how much relative to the other factor.

Many thanks - and I'll let you know the results when they are analysed.

Island compost toilets - by: KeithBell http://forum.susana.org/forum/categories/67-sanitation-systems-for-special-conditions-resiliant-risk-reduction/8211-island-compost-toilets#8211 http://forum.susana.org/forum/categories/67-sanitation-systems-for-special-conditions-resiliant-risk-reduction/8211-island-compost-toilets#8211 Small islands are closed systems, microcosms of the planet.

This documentary details the challenges of small island sanitation:


I find it especially interesting how this combination of poor sanitation and the traditional root vegetable diet of the Pacific Islands has resulted in the world's highest rates of obesity. Root vegetables are very high in resistant starch possibly feeding an overgrowth of Firmicutes intestinal bacteria associated with obesity, diabetes and heart disease. This would occur over generations such that children are born predisposed to obesity, a matter of microbial predisposition. Sanitation is not yet commonly associated with global obesity epidemics, but I wonder if poor sanitation is a major factor in obesity epidemics, i.e., Persian Gulf nations.
en.wikipedia.org/wiki/Obesity_in_the_Pacific

We have the exact challenges here in Florida, USA as we pollute important coastal waters with septic waste and nutrient-laden water discharges from Lake Okeechobee. The Indian River, for example, is in peril for these reasons. I'm presently on a team having notified Florida Department of Health of a lawsuit claiming they have violated the Endangered Species Act in allowing septic waste to threaten the Indian River Lagoon (IRL). Here's our website; my input including links is under Re-Plumbing the Future:

A number of questions occurred to me as I was watching it though, and I was hoping you could share a little more information about your work! First how long has the system been in operation, and how many people in the town does it employ? What has the community's experience been with the vacuum system, and have there been any significant or unexpected operational or maintenance challenges with either the sewer or treatment system itself? If the project were to be replicated elsewhere, how much would you estimate that the entire system would cost per capita? And how much longer is this project funded for?

Sorry to bombard you with questions, but it is a fascinating project that I (and others) would be interested to learn more about! Thanks for sharing it here.

Best wishes,
Amanda

congratulations for the first CuveWaters post!
I am really happy that you posted the film on the SuSanA Forum as such a large community is present there and eagerly discussing any aspect of sanitation.

I really hope that this is the beginning of a fruitful exchange between the project and SuSanA forum.

All the best,

CuveWaters: Sanitation & Water Reuse in Namibia - by: CuveWaters http://forum.susana.org/forum/categories/67-sanitation-systems-for-special-conditions-resiliant-risk-reduction/8044-cuvewaters-sanitation-a-water-reuse-in-namibia#8044 http://forum.susana.org/forum/categories/67-sanitation-systems-for-special-conditions-resiliant-risk-reduction/8044-cuvewaters-sanitation-a-water-reuse-in-namibia#8044 new short film about the Outapi sanitation system was released www.cuvewaters.net/Documentary-films.66.0.html

What is the film about?

Water is a scarce commodity in Namibia. The natural resource is coming under increasing pressure due to climate change, a rapidly growing population and the exodus from rural areas. The project team of CuveWaters, led by ISOE – the Institute for Social-Ecological Research, has succeeded in turning wastewater into a resource in this most arid region of the world, so that processed wastewater from sanitary facilities can be used for agricultural purposes.

Approximately 850,000 people live in central northern Namibia. About 40 percent of the population in urban areas don’t have access to adequate sanitary facilities. In order to improve the sometimes dramatic situation for the population, the „Namibian Sanitation Strategy“ recommends using efficient flushing toilets in conjunction with innovative wastewater technologies. As a result, the CuveWaters team has developed a novel sanitation concept plus vacuum system within the framework of an integrated water resources management (IWRM): The sanitary facilities are part of a complex disposal, treatment and reuse system that has been developed together with the local population and with Namibian partners from government and industry.

Energy efficient: Sanitation concept with water reuse in Outapi

The small city of Outapi (Omusati Region/Namibia) was chosen as the site to implement the sanitation system with water reuse. It is home to 4,600 people, of whom 1,500 have been using the new sanitary facilities in a pilot plant since the beginning of 2013. The official handover of this plant to the municipal administration is now coming up on November 1st. The energy-efficient sanitation and wastewater concept in Outapi works this way: A vacuum system transports the wastewater from settlements in Outapi to a processing plant, where it is purified. A multi-step purification process produces hygienically impeccable irrigation water. Together with the nutrients, the purified water is then used in the fields. A farmers’ cooperative works this land and sells the crops at local markets. Biogas is also won in the course of the purification process, which is used to generate power and heat. This covers a percentage of the operating energy of the vacuum canalisation and the wastewater treatment plant.

Promoting millennium goals through the transfer of technology and knowledge

The innovative concept isn’t just ideal for small rural settlements, but also opens up completely new perspectives for rapidly growing urban areas in particular. Within this context it is vitally important to involve the local population, as well as training and educating them. “Together with the ‚Community Health Clubs‘ which have arisen locally and which help people with hygiene issues, CuveWaters also makes sure that knowledge transfer takes place, in addition to technology transfer,” says project leader Thomas Kluge (ISOE). The cultivation of agricultural areas also opens up new sources of income for farmers. “Altogether, this allows us to improve the living conditions of the population over the long term and make a contribution to reaching the millennium goals, which also include safeguarding health.”

I only saw your post only now but have hared from the project your are planning in Sénégal together with Eawag.
I just came back from Sénégal where we had a one week seminar with regional actors in the South (Kaolack) on Scaling up Rainwater harvesting and productive sanitation for increased food security, health and social development.
I was involved most on the sanitation parts, but my partners are all experts in the RWH field, both urban and rural: IRHA, RAIN, Aqua-Aero and have implementation experience with Caritas and Pecam and others… IRHA is more on the urban side while rain and aqua-aero are having competencies for both, agriculture as well as drinking water on community level.
More such interventions are in the pipeline, potential of RWH in Sénégal is huge and so are the needs of the potential having a combination of many different serious water availability and quality problems.
Please contact me via email and I can give you more information/contacts….

I'm an architect-urbanist running a consultancy with a focus on sustainable urban solutions for the growing african metropols. Our services reach from sustainable housing solutions (naturally includes water and sanitation solutions) to sustainable urban development and transportation systems.

That can be for example as for the project in Senegal to develop solutions to upgrade informal settlements witout having to displace the inhabitants. Improving the urban, social and economic structures of this neighborhoods and introducing basic infrastructures. The field of actions are mainly in Senegal, Angola and Mozambique.

That a short introduction of myself

I didnt realy understand your question
But probably thats because I'm completely new in this forum

But thank you again for your links.
What I'm looking for are solutions or experts whith experience for waterharvesting in public space in densely populated areas as urban gardening / urban greening solutions. The focus is to try to use a maximum of the water locally and to have more retention and storage in order to reduce the amount of flooding water needed to be pumped away.

The idea of harvesting water from the roofs could be a very good addition from the individuals to reduce the amount of flood water.

Who would you recomend me to contact from the Lanka Rain Water Harvesting Forum?
