Water Conservation for Business/Industry
- Develop a water conservation plan.
- Educate and involve employees in implementing the water conservation plan.
- Install ultra-low flow toilets, or adjust flush valves or install dams on existing toilets.
- Install faucet aerators and high efficiency shower heads.
- Install high-pressure, low-volume nozzles on spray washers.
- Install in-line strainers on all spray headers; inspect nozzles regularly for clogging.
- Equip hoses with spring loaded shutoff nozzles.
- Use water-conserving ice makers.
- Eliminate "once-through" cooling of equipment with municipal water by recycling water flow to cooling tower or replacing with air-cooled equipment.
- Replace high-volume hoses with high-pressure, low-volume cleaning systems.
- As appliances and equipment wear out, replace them with water-saving models.
- Detect and repair all leaks.
- Minimize the water used in cooling equipment in accordance with manufacturers recommendations. Shut off cooling units when not needed.
- Identify discharges that may be re-used and implement re-use practices. Some discharges with potential for re-use are:
- final rinses from tank cleaning, keg washers, fermenters
- bottle and can soak and rinse water
- cooler flush water, filter backwash
- pasteurizer and sterilizer water
- final rinses in wash cycles
- boiler makeup
- refrigeration equipment defrost
- equipment cleaning
- floor and gutter wash
- Use fogging nozzles to cool products.
- Handle waste materials in a dry mode where possible.
- Adjust overflows from recirculation systems by controlling the rate at which make-up water is added: install float-controlled valve on the make-up line, close filling line during operation, provide surge tanks for each system to avoid overflow.
- Turn off all flows during shutdowns. Use solenoid valves to stop the flow of water when production stops.
- Adjust flow in sprays and other lines to meet minimum requirements.
Kitchens and Laundries:
- Turn off dishwashers when not in use. Wash full loads only.
- Scrape rather than rinse dishes before washing.
- Use water from steam tables to wash down cooking areas.
- Do not use running water to melt ice or frozen foods.
- Handle waste materials in a dry state whenever possible.
- Wash only full loads of laundry or select the appropriate washing cycle provided on the washing machine. Use a rinse water recycle system. Consider purchasing high efficiency equipment.
- Wash vehicles less often; use a commercial car wash that recycles water.
- Sweep or blow paved areas to clean, rather than hosing off.
- See Landscapes for additional information.
