Water Efficiency Measures for Commercial Businesses

Adopted from EPA’s Website.

Please note that these suggested measures are not intended to supersede more stringent state, Tribal, or local health and safety regulations.


  • Designate a water efficiency coordinator.
  • Develop a mission statement and a plan.
  • Educate and involve employees in water efficiency efforts.


  • Install ultra-low flow toilets, or adjust flush valves or install dams on existing toilets.
  • Install faucet aerators and high efficiency shower heads.
  • Use water-conserving ice makers.
  • As appliances and equipment wear out, replace them with water-saving models.
  • Eliminate “once-through” cooling of equipment with municipal water by recycling water flow to cooling tower or replacing with air-cooled equipment.


  • Detect and repair all leaks.
  • Minimize the water used in cooling equipment in accordance with manufacturers recommendations. Shut off cooling units when not needed.


  • Wash vehicles less often; use a commercial car wash that recycles water.
  • If you have a swimming pool, consider a new water-saving pool filter.
  • Lower pool water level to reduce amount of water splashed out.
  • Use pool filter backwash for landscape irrigation.
  • Use a pool cover to reduce evaporation when pool is not being used.
  • Sweep or blow paved areas to clean, rather than hosing off.
