- Higher temperatures increased biofilm formation on High-Density Polyethylene (HDPE) pipes in a chlorinated drinking water distribution system (DWDS).
- Material accumulation was accelerated by temperature but this did not effect biofilm strength
- Temperature triggered changes in the microbiome of the DWDS and changes were more notable in biofilms.
- Pseudomonas and Fusarium proliferated with temperature increase and have an enhanced capability to promote biofilm development, thus compromising further water quality.
- Temperature rise increased detection of Mycobacterium in biofilms and favoured presence of M. avium complex in water and biofilm samples.
- Risks need to be mitigated to prevent the effects of unavoidable climate change
