It may be a little late in the day, but is it ever really too late to celebrate coffee?

Happy International Coffee Day! Coffee may get all the credit, but water is doing most of the work. Here’s to full mugs and one more cup… if you dare!

Hats Off to Our Local Fire Departments!

You may begin seeing local fire departments flushing hydrants throughout our communities. This routine work typically takes place between Labor Day and Memorial Day and helps ensure hydrants are ready when they’re needed. Customers nearby may temporarily notice changes in water pressure or some discoloration. If your water appears discolored, simply run the cold water for a few minutes until it clears.

A big thank you to our local firefighters for all they do to keep our communities safe!
