I am very agree with David and Alex. I only now two good experiencies with communal digesters, and both are related to isolated indigenous people fron the Bolivian altiplano that have their own tradicional way to share. but experiencies with communal digesters with non-isolated, but indigenous, people have not work.Also happend in rural schools, where many times the parents anrd/or teachers have asked for a digester for the school, but finally all this projects, after two year,s have fallen.
Other questoin is if you have the manure, you install your own big digester, and you sell the biogas to the neighbours, then you'll have to be very clear about the distribution of gas. To sell the bio-slurry is easiest.

HI Rabin, 
As David says, these schemes often look good on paper, but fall into tragedy of the commons.  Run by a wells structured group or government you will remove some of the issues but the gas distribution will still be an issue whether or not you want a pipeline network or are trying to transport gas bladders.  There are lots of issues around how much waste is delivered and how gas and slurry are metered.  If there are fixed inputs, then producing electricity on site makes sense, or finding centralized thermal uses.  

We have tried on about six different occasions to try group biogas plants in Mexico with cooperatives and they have all failed until the group structure fell apart and a single family took the plant over and ran it successfully (as a household system). This is consistent with many projects around the world, including David's comments above.  I really suggest you avoid this scheme unless there is already a solid structure in place that would support it, such as joint waste management or a multifamily farm endeavor.    

Best, 
Alex

Rabin, Hello,
 
Several years ago, in Nepal, we (DCS at the time) worked with the ADB Small Farmers Development Programme to set up a number of small community biogas plants. The information is available in my book: "Running a biogas programme: a handbook"  (developmentbookshop.com/running-a-biogas-programme-pb). I am in the process of writing an updated version of this book.

 
The SFDP workers were rather frustrated by this project. They had to spend a lot of their time stopping arguments within the groups as to how much dung each family put in and how much gas they were using. The individual household programme became very successful (now BSP-N - www.bspnepal.org.np/), but the community biogas programme had to be regarded as a failure. 

 
Best wishes,
David

Hello,
 
I need some help regarding the promotion of biogas in rural areas. As of now, in rural areas biogas plants are installed in individual households but now we are thinking of promoting single (big) biogas plants for a group of households ( it could be 10 or more households). This biogas plants will be run by an individual person or LFIs ( any entrepreneur) then they will sell gas to households. 

 
So I want some information, if this kind of model has been used in any other place. If you can provide any related information then I will be really thankful. I also want to know if this is feasible or not ?

 
Regards,
Rabin
