Since some here are in regions with serious water depletion issues, I thought it might be interesting to hear what typical water usages are for forum members. I'll start with my own (two adults, two kids, modest yard): In-home use ran about 5.8 kgal/month over the past year. Lawn use ran about 10.1 kgal/year. The annual total was a little less than 80 kgal/year. Rates here are about $3+/kgal. Primary water consumption for us is four showers/day, 1 dishwasher load/day, 1 load of laundry/day, handwash of misc. dishes 2-3 times/week, cooking use 1-2 times day, some lavatory sink use, uknown number of toilet flushes. I've taken a few steps that have reduced our consumption, some of which are already reflected in the average above: 1 low flow showerhead, 1 front loading washer, insulating hot water lines (so that taps/showers come to temp faster.) I'm a believer in minimal lawn watering but took over from someone who seriously overwatered the lawn, so I had to water it more than I liked last year to keep it alive. This year's water conservation plans include: another low flow showerhead for the master bath and one high efficiency Toto toilet (1.28 gpf). If the high efficiency toilet works well, then I'll probably repeat in the other two baths. As I understand it the ecoDrake I'm looking at can be converted back to 1.6 gpf by changing flappers so there is little risk in the experiment. The current 1994 vintage toilets are marginal flushers, retiring the plunger is the primary motivator for replacing them. Hopefully the above changes will knock water use down by another 1 kgal/month and get us down to around 4 kgal/month excluding lawn irrigation.
