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. Includes tables, figures.
