The City of Vail is advising residents they will be conducting their semi-annual hydrant flushing procedures beginning tomorrow (Thursday). According to city officials, crews will be opening hydrants throughout the community to clear water mains of debris or mineral deposits within the lines. This could result in discolored water from taps in homes and businesses. While the rust-colored water is safe to drink, it could potentially stain clothes running through the laundry. If discoloration occurs, city officials recommend residents open taps in their homes until the water runs clear. For more information, contact Vail City Hall at 712-677-2210.
