06./07.11.2012 - NASS-Tage Eschborn

During two days at the GIZ headquarter in Eschborn, specialists from Germany and other Countries are shown results from their projects about sustainable sanitation world wide. The big topic was “New water infrastructure concepts in town planning”. Organizer was the DWA. For more information of GIZ work in sustainable sanitation visit www.saniresch.de

13.09.2012 - The Governor of Darkhan visits the biogas plant

In September 2012, the Governor of Darkhan visited the biogas plant. The pilot biogas plant produces biogas from a substrate of faeces and sludge from the wastewater treatment plant. Kitchen garbage can be co-digested as well in future. The Governor's visit was accompanied by many interested citizens of Darkhan and the local press as well.

27.08.2012 - Organic waste for biogas plant

The waste collection in our case study “Bag 7” started at the 15^th of August with more than 70 families and finished at the 22^th of August. The aim of this collection is to find out how much organic waste and recyclable waste (plastic, metal, paper, …) can be collected in the total bag. In future, the organic substances should be used in the biogas plant for a co-fermentation. For the recyclable fractions, we are planning options for treatment facilities. Furthermore, we are developing a conception for a collection system and its implementation in “Bag 7” representatively for the ger settlements in Darkhan.

24.08.2012 - Installation of electrical ventilation

Ongoing monitoring and development of the iPIT has highlighted the need to add a new technical part to the toilet. Because of users complaining about a cold breeze from the inside of the toilet especially in winter, two different kind of fans have been installed. These have been placed underneath the delivery pipe to direct the air stream in the right direction. In hindsight, this should have been done using natural ventilation by using the chimney effect (black pipe to heat up the air inside).

The first fan being tested is slightly larger than the other. It requires more energy, therefore problems may occur due to the inconsistent power supply. The second one is an ordinary computer fan. It seam to work well, but because an added component of a transformer is needed, the costs are more or less the same.

30.07.2012 - Students going to Darkhan

Beginning of August 2012 a group of eight students of Bauhaus-Universität Weimar will be going to  Darkhan, Mongolia. The interdisciplinary team of junior scientists (environmental engineers, media experts, urbanists) will collaborate with Mongolian students and experts at the two universities in Darkhan.

The students work on different topics like:

• improvement of the waste management system in Darkhan and reuse options for recyclables and organic waste


• finance model for wastewater treatment and waste management in Darkhan


• strategies for reuse of products from urine and feces as a fertiliser in the local agriculture


• technical improvement of the iPiT
