Researchers at the University of Illinois Chicago have developed a mathematical model to simulate how bacteria grow in plumbing systems. The model can be used to identify the factors that most influence bacterial growth and to develop strategies for controlling it.

The researchers created the model using a variety of data, including measurements of bacterial growth in different types of pipes, information about the water chemistry in those pipes, and data from previous studies on bacterial growth.

The model showed that the most important factors influencing bacterial growth were the temperature of the water, the availability of nutrients, and the presence of other bacteria. The researchers also found that the type of pipe material and the design of the plumbing system could also affect bacterial growth.

The researchers said that the model could be used to help design plumbing systems that are less likely to support bacterial growth. This could reduce the risk of infections and illnesses caused by bacteria in drinking water.

The research was published in the journal Applied and Environmental Microbiology.
