Abstract
Biofilm formations on pipe walls have been found in potable water distribution mains. The biofilm layers contribute to accelerated corrosion rates, increased flow resistance, and formation of encrustations that may deteriorate drinking water quality. Research to evaluate the dependency on viscous pipe flow parameters and conditions at the pipe wall was identified from experiments and analysis of biological rates of formation for the growth process and sloughing away of constituents.
