under house compost collection?

Hello,
I am working on a composting toilet plan for my new bathroom. I am trying to keep the price low and, I would like to have the collection under the house and urine seperation.  So far my working plan is as fallows.
A wooden binch similar to a bucket system. Then using a sump basin turned upside down with bottom cut out as a chute to a 15 or so gallon drum under the house. I am in the early stages of planning and am looking for ideas. I have looked at commercial outhouse pedistals as an option. At around 200$ delivered its not bad price but im not sure how much trouble a urine seperator would be to add to one.
Thoughts? Idea?
I will try to add a drawing in the near future.

Every pick up a FIVE gallon bucket full of human waste?  It's HEAVY.  15 gallons might be immoveable.  Unless you've got a system where the buckets are on flat ground, and maybe have wheels, larger buckets or tubs will be hard to move.  Access is key, as is the weight of the buckets.    

hey nicholas,
welcome to the forums.

with urine seperation, the buckets would be much lighter. but wheelie-bins could be an option.

have you thought about a two chamber/vault system? adding composting worms would speed up composting process and reduce the space needed to store the STUFF.

have you lookded into ventillation and ways to keep flies out?

good lukc

I am watching this topic because I am intrigued by the idea of under-the-house management of the waste.

My concern is ventilation, there may also be other concerns that I haven't thought of.

I do like the idea because we permies do face problems with 'the mainstream' attitudes and I have found that sometimes it is in our best interest to keep our lifestyle out of sight of those who can't think out side of the box.

for ventillation there s the thing with that vertical pipe that goes from under the toiletseat to above the roof.
it should be covered with fly-netting on the outside. it can be painted black on the outside to warm up air and to suck more aire from the iside to the outside.

my plan is to use a 12V motion sensor module with a timer (like adjustable from 30 sec to 5 minutes, costing about 13€). this will be connected to a mini 12V fan that vents from under the toilet seat to the outside. it will be connected to LED-lights. so when you enter the toiletroom, the light will go on and the fan will start to draw air out, even before opening the cover above the tolet seat.

this should be convenient, cheap and do the job.
