There are many ways in which a craft brewery can reduce water use.
Having efficient water management practices won’t help if they are not written down and reinforced through employee education and training.
Cleaning Procedure for 200 bbl Bright Tank
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.
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)
Install water saving automatic shut-off nozzles on hoses.
Using water saving nozzles can reduce hose water consumption by 30%.
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.
