Overall Strategies

Overview

Best Practices

  • Shut off water using equipment when not in use.
  • Set equipment to the minimum flow rate allowable per the manufacturer’s recommendations.
  • Run glassware washers at full load only.
  • Retrofit steam sterilizers with controls that automatically sense the need for tempering water.
  • Install expansion tank instead of using water to temper steam in steam sterilizers, if it does not interfere with the normal operation.
  • Increase the recovery rate of water purification systems with pre-treatment and optimization of the flow configuration.
  • Consider reusing discharge water from water purification systems in non-potable applications.
  • For new water purification systems, choose equipment based on high recovery rate.
  • Eliminate water stills. Use reverse osmosis or ion exchange methods when possible, to save water and energy.

Guiding Principles

  • Indoor Water Use ( Guiding Principles [EB])
    Section: <span>III. Protect and Conserve Water</span>

    Guiding Principles for EB: “Employ strategies that measure and minimize water usage, including:
    (i) Conduct an analysis and take action to monitor facility water use and identify and implement conservation opportunities.
    (ii) Purchase water conserving products, including WaterSense and FEMP-designated products, as required by statute.
    (iii) Install building level water meters to allow for the management of water use during occupancy, including detection of leaks.
    (iv) Optimize cooling tower operations.
    (v) Eliminate single pass cooling.”
    Determining Compliance: “Install building level water meters, reduce water use 20% below FY 2007 baseline, and use water efficient products, or install building level meters, conduct an analysis of water use, identify and repair leaks, eliminate single pass cooling, optimize cooling tower operations, and use water efficient products.”

    Guiding Principles for NC: “Employ strategies that minimize water use and waste, including:
    (i) Purchase water conserving products, including WaterSense and FEMP-designated products, as required by statute.
    (ii) Install building level water meters to allow for the management of water use during occupancy, including detection of leaks.
    (iii) Optimize cooling tower operations.
