Additional Information About Tap Water

The availability of clean, safe, healthy drinking water is something most of us take for granted. The water that flows from your tap is more than just a convenience; it contributes to the quality of life that we all enjoy. A well maintained water system is critical to public health, fire protection, and comes at a value that can’t be beat when compared to bottled water.
