Clean in place (CIP) is one of the largest consumption points and creator of effluent waste in a brewery. By defining CIP, impingement, factors that affect a good CIP, and device types used, this paper provides information focused ultimately on water conservation. A review of the traditional static "spray ball" shows that water usage is extremely high while it lacks cleaning effectiveness. Two-dimensional devices are reviewed for the same characteristics. Since many commercial breweries have CIP systems that were installed 20 or more years ago, three-dimensional devices are reviewed, including a case study. In the case study, a simple nozzle change resulted in a savings of 2,000 gallons per CIP on a fermenter. This savings also translated into over $1,800 per year.
