Re: Practical and technical questions on use and installation of SaTo pan

THe SaTopan is generically related to the microflush valve we developed years ago and have been using on the GSAP Microflush toilet. The 'pan' releases waste with a handle and the water seal is made with just 150 cc of water from the previous user's hand wash. It is made with local parts - PVC, a pan (which can be press molded from PVC sheet and a concrete counterweight. The toilet MAKERs we have trained around the world are versed in making these. We have an auto flushing one but there is sensitivity to the correct counterweight.

Re: Practical and technical questions on use and installation of SaTo pan

Where can I find more details of the GSAP microflush? Concept sounds good but I can't find a good photo to match your explanation.

It would be great if there was a very clear 1 pager to help spread the knowledge of this system with diagrams. I've searched online and found 2 explanatory videos - neither of which actually showed an example of the system.

Re: Practical and technical questions on use and installation of SaTo pan

Hi Nicola,
Steve might provide more details and photos, but meanwhile you can find some information here in the project database (the project title at the time was "Prototype Microflush-Biofil Toilet Facilities"):
www.susana.org/en/resources/projects?search=GSAP

Or directly here in this forum thread:
forum.susana.org/forum/categories/106-us...roject-usa-and-ghana

Oh and there's also this forum category about "Toilets with combined vermicomposting and filtering (such as Biofil toilet)":
forum.susana.org/forum/categories/205-to...uch-as-biofil-toilet

Hope this helps, and looking forward to further discussion (maybe rather, or also, in that thread, not in the SaTo pan thread).

Regards,
Elisabeth

Re: Practical and technical questions on use and installation of SaTo pan

Hi, I am very interested to hear details of peoples experience when using the SaTo pan with off-set latrine pits. In particular:
- Was the SaTo pan installed with or without the complimentary SaTo Collection Box?
- And have people found any blockage issues due to the build-up of faeces/solids in the pipe connecting to the off-set pit due to the small amount of water used to flush the SaTo pan?

The key concern I have when installing without the plastic collection box is that faeces might easily get stuck/block in a concrete collection box. A concrete collection box would have a much 'rougher' finish than the plastic version, and with the small amounts of water used to flush the SaTo I thought this could easily lead to significant blocking issues. Particularly in Cambodia where off-set pits are common (instead of direct pits).

Any comments on experiences welcome!

Thanks,
Andrew

Re: Practical and technical questions on use and installation of SaTo pan

Dear Andrew,

Thanks for your interest in SATO.

BRAC in Bangladesh has installed literally hundreds of thousands of SATO toilet pans in offset pit latrines. Before the introduction of the SATO collection box they utilized hand-constructed concrete collection boxes, but now exclusively use the SATO collection box due to reliability, performance improvement, and reduced construction costs.

The new SATO GEN2 product line which is about to launch in India is an even further improvement for construction of offset pit latrines. Please refer to links below for more information.

Jim
