Dear Krischan,

welcome to the SuSanA Forum and thank you for your introduction. Which is your university and your field of interest?

Regarding your question on vacuum sanitation systems: I know one project with a vacuum system at the Tsinghua University in Beijing, China where the Sino-Italian Environment & Energy Building (SIEEB)has been equipped with a conventional system on one wing and an alternative systems at the other wing of the building. The alternative system includes a vacuum sewer as well as urine diversion toilets. I visited the project in 2009 and it was running quite. At this time there was no reuse of the collected urine, but I am not sure if this is also from your interest.

There is a SuSanA case study on that project where you can find more information: www.susana.org/lang-en/case-studies?view...ypeitem&type=2&id=37

The SuSanA Library shows 7 documents using the search function with "vacuum": www.susana.org/lang-en/library?showby=yeardesc&search=vacuum

Btw I think vacuum systems are an interesting option but due high costs it does not seem to me a good solution for low-income areas.

Cheers,
Philipp

First off: hello to everyone here on the SuSanA forums.
I got to know about this forums over at the WASH forums where I am posting quite often.

About me? My name is Krischan and after a some experience in the development sector (mostly drinking-water and emergency context) I am now back at a University research institute in Germany working on various topics related to WASH. Edit: changed jobs since then.

So this brings me to my question
Does anyone have some ideas or feedback to give on the general concept of vacuum sewers in a development context?
I already posted about this in more detail on the WASH forums:

www.watersanitationhygiene.org/forum/php...pic.php?f=370&t=1242

I am well aware that there are various reasons why this technology is probably considered unsuitable at first glance, however I am currently of the opinion that some creative thinking could change that (especially when combined with water-reuse and/or simple bio-gas production).
But any feedback is highly appreciated!
