Biofilm can alter water quality in pipes. Its development is favored by breeding practices and conditions. Biofilm management in drinking water pipes is a major issue to prevent disease and to reduce antibiotic consumption and resistance. The aim of this field study is to assess the effect of purging pipes during breeding on development of biofilms, water quality, amount of water used, and breeder’s health. In order to achieve this goal it was necessary to create a methodology to characterize biofilm. A scoring method was developed, each score being definite by a picture and objective definition. The chart created was used to characterize biofilm at each observation, and to estimate its evolution during the breeding. First results highlight the importance of cleaning the pipes before starting the flock breeding. Daily and highly frequency purges seem to delay biofilm development inside pipes when compared to never purged pipes.
