Standard

Notes:

• Rear outlet version does exist for Niagara 0.95 gpf [1]
• Tuscany 1.1/1.6 gpf - [2]
• Niagara The Original 0.5/0.95 dual. Specification is impressive [3]. $191 - [4] [This model is compatible with N7717, N7716 and N2235RB]. Does not appear to be a flush and brush system from good reviews [5].
  • More - $284 [6]
• Niagara Nano - even better at 0.5/0.8 gpf. $311 - [7]. Reviews?
• Niagara Nano exists in 0.8 single flush [8]
• tank only $148 [9]

Model Numbers

• Niagara catalog - [10]. Includes 1/2 gpm aerator showerheads
• N771614R-DF - Round, 0.5/ dual Niagara Original
• N7737EB/N7747T-DF - Niagara Nano
• Says the 0.8 gpf model [11] is compatible with the 0.5/ dual toilet.
• Dual flush nano tank - Part #NN7747TDF

Notes

• ultra low water used, lowered water bill imediately - dual flush tank only is $124 [12]
• 8 average bathroom visits per day [13]
• This one says 6 times per day or 10 gpd with low-flush 1.6 gal - [14]
• 6 gallons per person per day is saved if we use 0.5 gpf. Average household of 2.5 [15] thus saves about 5500 gallons per year.
• 1/4 to 1/3 of water bill is spent flushing money down the toilet [16]
• Avg water bill is $50. Water saving toilets thus save $15 of this per month, or $180 per year.
• If we calculate from gallons, take around 5000 gallons per month - [17]. Equals to a cent per gallon on a $50 water bill.
• For 5000 gal/month - a home saves 18,000 gallons of water per year. This is just for average 2.5 person household size.

Communications

• Multiply your 5 cents times 6 per day times 365 days and you have $110 per year. That is for a single person. Average family in the USA is 2.5, so if this average family wants to flush an added $275 per year down the toilet - they are welcome to do so. I would rather keep 3 crisp Benjamin Franklins in my wallet, not to mention lower taxes if the sewer utility needs to process 25-30% less water if everyone believed this. For example - used a superefficient Niagara Nano - see the specs: https://fergusonprod.a.bigcontent.io/v1/static/7546005_6335032_specification. Reviews on Home Depot indicate that this is not a flush-and-brush toilet - one flush seems to work for solids. We are getting 6 of these for our school, as we are interested in saving 180,000 gallons of water per year.

Eco

If things aren't ready yet for building a septic system or a blackwater-capable large scale Living Machine there are these quick off-the-shelf options.

Compact composting toilets;

http://www.sun-mar.com/

(limited in capacity and so sometimes finicky. Compost suited to gardening, but people tend to prefer using it for non-food crops even if there's no technical reason for it. Must avoid chemicals and drugs in the blackwater stream)

Marine-type incinerating toilets;

http://www.incinolet.com/

(power hungry, expensive, uses consumable paper liners, needs good wind flow in the region and tall vent pipes, but the cleanest, most convenient, and low in maintenance -and helps keep the bathroom warm in winter... Ash is dry and odorless and can be safely put right in the ground or in the trash -or into the sea for that matter. Standard equipment on many yachts and for the Sea Room vacation housing developed by US Subs)

Larger scale composting systems;

http://www.clivusmultrum.com/

Tends to need basement installations but serves whole buildings.

I also recommend this book, both for the art and the subject;

http://www.amazon.com/Septic-System-Owners-Manual/dp/0936070404/ref=sr_1_2?ie=UTF8&s=books&qid=1240294427&sr=1-2
