A. Customers may notice warmer water from their cold water faucets.
B. Shifts in algae populations may occur in the open reservoirs, which could affect the taste/odor of our drinking water.
C. Minimal impacts will be seen as underground water mains act as a refrigerator. Water temperature fluctuates only by a few degrees throughout the year.
D. As water temperature increases, chlorine disinfectant levels can decrease.
This year, these impacts are seen sooner due to the mild winter and spring and 90 degree temperatures in June. The Portland Water Bureau monitors algae in the system to ensure that no harmful species are present. Additionally, chlorine levels are adjusted seasonally to maintain adequate disinfectant levels to protect public health.
