Using Water Efficiently
Ideas for Industry
Please note that these suggested measures are not intended to overrule otherwise applicable federal, state, Tribal or local health and safety regulations.
- Appoint a water efficiency coordinator. Educate and involve employees in water efficiency efforts.
- Install high-pressure, low-volume nozzles on spray washers.
- Install in-line strainers on all spray headers; inspect nozzles regularly for clogging.
- Replace high-volume hoses with high-pressure, low-volume cleaning systems.
- As equipment wears out, replace with water-saving models.
- Equip hoses with spring loaded shutoff nozzles.
- Install ultra-low flow toilets, or adjust flush valves or install dams on existing toilets.
- Detect and repair all leaks.
- Identify discharges that may
be reused and implement reuse practices. Some discharges with
potential for reuse 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.
- Wash vehicles less often, or use a commercial car wash that recycles water.
- Discontinue using water to clean sidewalks, driveways, loading docks, and parking lots.
