Green features of plumbing

As my first project is an additional toilet, I tried to make a list of all the points I'd need to consider just for that. It didn't work out that way! I ended up starting a list about everything to do with plumbing, and although each of these will have their very own little blogpost eventually, this is it so far:

Policies and Design
- siting of all plumbing uses as close as possible to water sources, whether this means the water main or the tank. This minimizes "dead legs".
- integrating active and passive solar heating into the main system, including using a combi boiler.
- examining the treatment and re-use of black and grey water.
- materials used - plastic, ceramics, stainless steel, brass, titanium, granite, chrome, graphite. Are any of them greener than any other?
- knowing about the stop cock.
- the pros and cons of water meters.

Micro and macro, a miscellany
- energy efficient appliances.
- water butts.
- filtered water.
- waste disposal units. Oh dear...
- a strainer - basket strainer? - over all plugholes, to help prevent blockages, whether from human hair or kitchen waste.
- underground water tanks for rainwater storage.

Toilets
- a urinal at home!
- smaller cistern for toilets when refitting.
- using a hippo in larger, existing cisterns.
- dual flush.

Taps
- mixer or pillar taps? Monobloc? Disabled useage.
- aerating taps and showerheads.
- press taps or sensor taps, that switch off after a set number of seconds.
- pull-out spray and swivel spout.
- what type of valve inside the tap? Magnetic springs!
- inbuilt or add-on filtering and softening.
