High Efficiency Plumbing Credited with Water Efficiency; New Efforts Are Outside the BathroomBy
American Standard Toilet Scientist Jim McHale reporting from World Water Week:
I had the opportunity to attend several talks from leaders of municipal water utilities. A Los Angeles representative presented data that showed that LA’s total water usage has remained flat over the last 25 years despite an additional one million people living there. The water efficiency is attributed mainly to low-flow toilets.
So many water-efficient products are in Los Angeles area homes now that the representative said, “The single-family home opportunity is pretty much saturated.” An interesting metaphor, indeed. Future water efficiency efforts in Los Angeles County will focus conservation on public use.
Another presenter, from the Southern Nevada Water Authority had a similar view, speaking of indoor household water conservation in Las Vegas as being played out. They are focusing conservation efforts on outdoor usage like household and commercial irrigation.
Water efficiency solutions were of interest in not only drought-plagued regions. In Philadelphia where water is plentiful there is no special focus on conservation at all. Utilities in that city are focused on finding green solutions to reducing storm run-off.
