Cutting water to 1/3 its previous flow is a “considerable” cut; we need ask, though, whether actual monetary savings from this will be similarly considerable. After all, showers are but one source of water consumption. Washing clothes, flushing the toilet, and simple drinking or cooking: all of these use water in varying amounts. Has the owner broken down the average percent of water specifically used on showers? A few other questions here might be whether many apartments have washing machines. Also do many of the residents plan to buy such machines in the future? Does the climate vary much from winter to summer in Sunnyside’s setting? If so, shower use may run high in the hot season and fall off when the weather cools. What then is the climate here? What is the season now? When data as to water use is being examined? How much variation is to be expected?
