Use Only What You Need

There are many ways in which a craft brewery can reduce water use.

Create Standard Operating Procedures – Repetition is a Good Thing

Having efficient water management practices won’t help if they are not written down and reinforced through employee education and training.

Example: Wachusett Procedure for Cleaning Bright Tank

Cleaning Procedure for 200 bbl Bright Tank

  1. 2x30sec warm water rinse
  2. 2x30sec hot water rinse to raise tank to 120F
  3. Add 100 gal of hot water and 1 gal of caustic
  4. Circulate for 20min
  5. Drain
  6. 2x30sec hot water rinse
  7. 2x30sec warm water rinse
  8. 1x30sec cool water rinse to lower tank below 100F
  9. Set glycol to 32F
  10. 2min Iodophor rinse

Don't be Afraid to Improve

Continually revisit water management practices to see if things can be done better is a good practice.

Common triggers for review could include changes such as new chemical products, new equipment and/or increased production.

Example: More Isn't Always Better

Wachusett Brewing Company

Wachusett Brewing Company took a fresh look at their cleaning procedures for their bright tanks and identified opportunities to make them more efficient. They reduced the number of initial rinses and their length, and the length and volume of water used in the caustic wash (down to 0.5 gal per BBL of tank capacity), without any impact to sanitation effectiveness. These basic changes required no investment and resulted in savings of around US$3,600 per year. (source: Worcester Polytechnic Institute)

Implement More Efficient Practices

Better Spraying

Install water saving automatic shut-off nozzles on hoses.

Using water saving nozzles can reduce hose water consumption by 30%.

Spray Nozzle
Spray Nozzle

Use impingement cleaning devices and rotary spray nozzles when cleaning tanks. Compared to simple spray balls, impingement nozzles can reduce water use by 30-50% while improving effectiveness and reducing cycle time.

Brush it Off

Use brushes and squeegees to clean solids from equipment and floors before washing with water. It uses less water, generates less wastewater and keeps stuff out of the drain.
