Modelling the consumption of water and other utilities

Breweries benchmark the consumption of water and other utilities to determine how well they are performing in this area. Specific consumptions vary however with the beer production volume. This effect can be taken into account by mathematical models which describe consumption as being the sum of a constant usage independent of the volume of beer packaged and a proportional usage.

Water management has become a very important aspect in the running of a brewery operation (1,2,3). One tool used to determine how well a brewery is performing in this area is by benchmarking the specific consumption of water against those of other breweries (4,5). When the water to beer ratios are lower than usual, water saving practices are thought to be in place. This is illustrated in Fig.
