Water Main Flushing

2023 Water Main Flushing Is Complete

Updated 09/22/2023

Discoloration of the water is expected during and after the flushing. Flushing in one area may create discolored water in other areas. Customers are advised to avoid washing clothes and those with hot water tanks are advised to avoid drawing hot water during the flushing hours and until any discoloration has cleared. It is expected that the water will clear by midday after the flushing. Customers may also experience low water pressure during the flushing. This schedule is subject to weather conditions or other unforeseen circumstances.
