  • Use of efficient “Waterbroom” for washdown
  • Installation of tamper-proof 0.5 gallon per minute aerators on faucets
  • Installation of conductivity controllers on the make-up water lines to cooling equipment and flow meters with conductivity controllers on the drain lines Investigation of unaccounted-for water use
