Rutherfordian-Economics: Water Conservation Part Two.

This post will be a compilation of water saving techniques and devices and not meant as a recommendation or endorsement.
I had heard of No-Flush Waterless Urinal for some time but just recently saw one at UCSB.

They all work like the picture below shows as I have seen. There are additional links for all items in the links section.

It works on a chemical trap (Blue Seal as above) that keeps the smell from escaping and the overflow spills into a normal drain as the trap is filled.

Not that the She-Pee Urinals will catch on except for remote/special events (How to beat the Glasto toilet horror). But this has not stopped the development of a P-Mate for Women that is a disposable cardboard funnel to allow women to pee standing up, and the P-Mate Urinal stalls.

Warning next link is graphic, that talks about Advice on how to Pee Standing up for Females.

So if there is waterless urinals how about toilets? Envirolet® Composting Toilets by Sancor™ uses a fanned aeration system.

And SunMar® self contained composters use a handled rotating drum (much as a normal composter does).

Lastly there are some basement types as in:
Waterless composting toilet systems make too much sense!! and Waterless Toilets. But I am not sure how the solid waste gets down the drain without water and thus defeat the benefits.

But one area that I feel would be good to use this technology is rest stops or public restrooms that are not high traffic areas. Waterless toilets or 'dry sanitation' systems has a couple of ideas on this:

If these techniques above did not reduce the smell from normal outhouses then maybe the aeration system shown above might also be a possibility.

Another technique that is much easier to implement is the Dual Flush Toilets. I first read about this in the 70's when it was being used in Japan, and is still the simple concept that if it is liquid waste and maybe a small wad of toilet paper then only a smaller amount of water is needed to flush the waste. According to the web site, average old toilets used 18.8 gallons per day and the new low flow ones are at an average of 9.1 gallons per day and their new dual flush is 6.9 gallons per day. Instead of legislating the low flow toilets I wish that congress had let the market decide on how best to reduce water consumption, but that is for another day.

And now for something completely different...

Art's glass toilet tests courage

An artist has created a usable public toilet in a glass cube to challenge the curiosity - and bravery - of people passing London's Tate Britain gallery.

Monica Bonvicini said visitors would have to "defy their own embarrassment" to use the minimalist cubicle, made from one-way mirrored glass.

It is impossible to see into the toilet, which will be free to use, but the person inside can see passers-by.

The work, called Don't Miss A Sec, uses a prison loo as a historical reference.
