Water Main Flushing Program 2025

Water main flushing occurs each year from late June to mid-August to clear mains of iron and calcium scale deposits to maintain high-quality water. This program will run for 8 weeks and will take place between the nighttime hours of 10:00 pm – 6:00 am.

Please do not use any hot water until you have operated your cold water taps to clear the line of any discoloration that may occur during flushing.
