Dear David,

I am just wondering if your question is the same that Paul van den Bosch raised and that we have been discussing in quite some detail here on the forum:
forum.susana.org/forum/categories/141-ot...-or-municipal-system

The design requirements look very similar.

(For easier reference, I have moved them both into this category on the forum)

Regards,
Elisabeth

Dear Susana members

I am part of a consortium developing a group of 30 homes near Portland, Oregon USA. We would like to create an ecologically neutral subdivision that allows these homes to flourish within an equitable share of earth's carrying capacity. Living in harmony with nature-net positive in water, energy, and produce.

We are looking for approaches to sustainable sanitation. In particular, a toilet system option for each home that:

1. effectively deals with the Yuck factor - Toilets acceptable by middle or upscale class of American residences.
2. system for multiple toilets per home
3. stores urine for garden utilization
4. composts the feces for eventual garden utilization
5. uses very little energy
6. uses no or very little water
7. economical
8. odorless
9. no additives at toilet
10. low maintenance
11. no visible excreta
12. approved for use in the USA

If you have or know of such a solution, please contact David Burdick at This email address is being protected from spambots. You need JavaScript enabled to view it.
