I'm looking for a simple blackwater treatment system for a house in Thailand. We are not restricted by govt/council regulations, however a dry composting toilet wouldn't be acceptable for cultural reasons.
Worm based systems interest me, particularly the one below, which we could build from concrete rings.
http://www.omick.net/other_toilets/other_toilets.htm Below are some relevant points/questions:
- The system would be for a single toilet, not greywater, another toilet may be added in the future.
- The toilet is not a standard flush, instead a small bucket is used for a manual flush using only a couple of liters.
- Our block is about 1.6 acres.
- We use well water for everything except drinking. The local (unenforced) rule, requires septics to be 50m from a well. Can anybody advise a safe distance for a worm system?
- Our area is tropical, with about 2,000mm rain. It's never flooded but the water table get's quite high in the wet season.
- Can anyone recommend min safe depths for sub soil drainage?
I hope I haven't provided too much information, Any help is much appreciated.
