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].

Model Numbers

- 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.
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.
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;
(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;
(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;
Tends to need basement installations but serves whole buildings.
I also recommend this book, both for the art and the subject;
