Impact of temperature and water source on drinking water microbiome during distribution in a pilot-scale study

F. Waegenaar, T. Pluym, et al.

This research explores how varying temperatures and water sources affect the drinking water microbiome over 137 days. Higher temperatures lead to increased bacterial cell densities, while the source of water plays a crucial role in community composition. Conducted by Fien Waegenaar, Thomas Pluym, Laura Coene, Jozefien Schelfhout, Cristina García-Timermans, Bart De Gusseme, and Nico Boon, these findings emphasize the significance of water source quality for biological stability in drinking water systems.

Abstract
This study investigated the impact of temperature increases (16 °C, 20 °C, 24 °C) and source variations (treated ground- and surface water) on drinking water microbiome in a pilot-scale distribution network over 137 days. Higher temperatures increased bulk bacterial cell densities, while water source significantly influenced both bulk cell densities and community composition. Biofilm cell densities remained unaffected by temperature, establishing a mature biofilm by day 70 with a core microbiome resilient to changes. Findings highlight the importance of water source quality for maintaining biological stability in drinking water systems.
