It's a worthwhile exercise and I'm glad I had the opportunity to take part. I hope it turns out well. I have been surprised at some people’s unwillingness to use the toilet. I would never bury plastic bags in my yard - bury waste maybe, but not in plastic bags. I'm out a lot these days. Some days I go out very early and come home late. I'm on the dole so you'd expect me to be home more, but even I am surprised by how little I'm at home. 98
A10.4 Post-trial survey results Question How easy were the compost toilets to use? Response Very comfortable 4 Comfortable 4 Neither comfortable nor uncomfortable 0 Uncomfortable 0 Very uncomfortable 0 What have been the positive experiences? What have been the negative experiences? Any other comments Were the instructions at the briefing adequate? Relative ease of maintenance. Waste that could be put to use. Proof that the idea could work in many circumstances Less water wasted, much cleaner/easier than expected. Easy to use. Lots of free nitrogen for the garden The improved use of resources from not flushing potable water down the sewer! And the ability to keep nutrients on site. simple and well-thought out package Easier than I had expected, all round - easier to use and to clean. Trying something new Being part of an important trial Ease of cleaning. Difficulty in cleaning the plywood surfaces Straw everywhere Extra ~10 minutes a day emptying/cleaning - but not really a big deal. Less room in the bathroom. The occasional "agricultural" smells... Perception (as opposed to reality) for some. Also the pending considerations of what will become of the growing wheelie bin of poo Bit of extra smell It's a bit tiresome having to empty the liquid every day; separating liquid and solid is a bit annoying; and remembering not to drop paper in pee was a pain. Smells Having to carry the buckets down the stairs every day None I can think of. Kids came round after a rough middle patch of not wanting to use them. Recommend diluting urine bucket outside or where there is good air flow. Good to be part of a trial that may make Wellington more resistant to disaster. My 4 year old used it and all the pee missed the bucket despite his best efforts, realize now that it would need to be raised for small children. In the awful event of needing to use this, I feel toilet replacement at least will be painless. Yes 4 No 0 Did not attend briefing 4 99
