EcoBuild: Toilets (waterless urinal & sensor on water tap)

Two toilets and a commercial tap sensor stood out at the Ecobuild expo:

One of the efficiency and eco objectives is a house that is water efficient.

Two slides, from different sources on domestic water use / water consumption:

My initial straw polling, is getting a strong reaction to the idea of a urinal, let alone a waterless urinal, from  at least 50% of the girls reacting!

Waterless Urinal

This has the potential to drastically reduce the amount of water used in the house.

They are marketed as “clean, green, odour free and waterless”.

I had it all explained to me on the Odourwise and Twyford stands. The module that fits into the bottom of the urinal converts all uric acid to a form that prevents lime scale, clogging up the system, takes away the smell etc. It seems that urine and water are a big source of limescale and other loo waste pipe problems, hence trying to dilute this away with (usually) lots of water.

All you need to do, is a few times a year (depending on use levels) replace the cartridge. In this photo the plastic bit on the top is the device to extract the Odourwise bit so that it can be replaced with a new cartridge.

A google search reveals there are a few alternatives, so more research needed.

My current thought is a urinal in the bathroom  off the main living area and also one in the bathroom off the study.

Also on show at Ecobuild 2012 will be the Odourwise™ Waterless urinals. Twyford Bathrooms offers the revolutionary Odourwise™ Waterless system for two of its urinal ranges, Centaurus and Galerie Plan. Centaurus is the first hybrid urinal that is truly waterless, combining maximum water savings with enhanced hygiene. The cutting-edge Odourwise™ Waterless technology requires neither chemicals nor electricity, keeping it eco-friendly as well as economical. The urinal is also entirely rimless, making it easy to clean (both within and outside the bowl). Installed with the Odourwise™ Waterless system, Galerie Plan offers the same cost-effective and eco-friendly benefits as Centaurus.

Toilet Sink Taps to be Sensor Driven?

Why use your hands to touch the tap to get the water flowing, before you’ve washed your hands ?

Why have the water running when hands aren’t beneath the taps ?

I need to check out the cost and any other implications. I assume they use a tiny amount of electricity, but best to check.

Combine the Sink and Loo ?

This great combined unit captures (there is an optional bypass if you don’t want it to, eg if you’ve cut your hand) the water you use to wash your hand and then stores this to flush the loo. Integrated 1 unit grey water system.

BUT, £2,500 !!!!!

I’m pretty sure I can have an entire house grey water system for a similar amount.
