Re: Communal wastewater characteristics and population equivalents in developing countries

Dear Dennis,

Your report on "Communal Wastewater Characteristics in Developing Countries, Desk Study to inform Sanitation System Design" looks excellent, thanks so much for sharing! I think many engineers designing treatment plants will find it useful.

And: Sharing is caring... So often we get people who ask questions, obtain responses and then move on but forget to come back to the thread and share their findings. So I am very grateful that you are different and that you are making this available to us. I am glad you found this forum helpful in giving you information.

Just a small thing: In your reference list, would you be able to provide the URLs for everything that you are citing? That would be really useful. If something is not yet online, we can upload it to the SuSanA library.

I'll also ask the secretariat to upload your report and the Excel files to the library (or someone from BORDA could do it, as BORDA is a SuSanA partner and partners can upload publications to the library themselves).

Regards,
Elisabeth

Re: Communal wastewater characteristics and population equivalents in developing countries

Dear all,

The following publication "Communal Wastewater Characteristics in Developing Countries" is now available for download in the SuSanA library under this link: www.susana.org/en/knowledge-hub/resource...library/details/3263

Thank you Dennis for sharing the study!

Kind regards,
Ainul on behalf of the SuSanA Secretariat

Re: Communal wastewater characteristics and population equivalents in developing countries

Hi Dennis

I am using the documents you shared as a reference for modelling mass flows of P, N, TS and H2O of sanitaiton system options for a case study in Nepal (and Ethiopia). They are very useful: thank you!
However, it is sometimes very difficult to understand the units of the values, particular in the database summary output in the first sheet of this document: " Wastewater Characteristics - Design Database" - can you give any information on that?

Thank you and best regards

Re: Communal wastewater characteristics and population equivalents in developing countries

Hi Dorothee,

thank you for your interest in my study and excuse the late response. Frankly speaking, I haven't been actively following up on SuSanA for a while.
As I've just seen your post about your research progress I assume that you found a workaround or answered your question already.
I should have mentioned the units in that database, I must have simply forgotten it when collating the data.

The units for water consumption and wastewater production are in L/cap*day, the parameters BOD, COD, TSS, N & P are in g/cap*d

Best regards,
Dennis
