This powerpoint presentation begins by providing information on the Saving Water Partnership that is guided by the Conservation Potential Assessment (CPA), an analysis tool providing life-cycle cost evaluation of the conservation potential for specific, and/or in combination with a group of measures. Research goals include: to inventory a representative sample of urinals in the joint service area to determine the distribution of the most common fixtures, age, condition, and other relevant characteristics; to examine the baseline performance characteristics of the existing urinal stock; and, to assess practicality and cost-effectiveness of alternative strategies to significantly reduce water consumption and maintain flush effectiveness in urinal fixtures found throughout the SWP. Application of research results include: designing a cost-effective urinal efficiency program to upgrade existing urinals; better estimating savings potential and actual cost; and, refine previous estimates of regional savings potential for urinal upgrades. Research objectives include: determining baseline characteristics of the current stock of urinals by collecting type, age, condition and other important performance data; determining urinal flush volume and flush effectiveness through field measurements; interview commercial customers to identify maintenance practices, urinal performance history, and decision makers for a urinal retrofit program; and, assess the practicality and cost-effectiveness of alternative strategies to reduce flush volume and maintain flush effectiveness. Observations include: maintenance staff use stop valves to minimize actual flush volume, many older urinals already operate at low flush volume; old urinals with single filter diaphragms flush at less than nominal flush volume even with the stop valve fully open; dual filter diaphragms provide better immediate savings and more consistent long term savings; urinal use is >100/day in public buildings and 11-50/day in private buildings; and, most facilities are interested in a urinal retrofit.
