![]() ![]() ![]() Peak usage is currently billed at the rate of $5.46/1 thousand gallons. Peak usage refers to the consumption of water in excess of the average consumption of the preceding two winter quarter billing periods (winter quarterly average). If you have questions about this program or the work being conducted in your area, you may contact the Department of Public Works.ĭuring the summer and fall months, the town charges a peak rate for water usage. These conditions are not harmful and should be of short duration. Flushing may result in some temporary discoloration and the presence of sediment in your water. Even with these precautions, some discolored water is possible. Where valves are exercised, a fire hydrant will be flowed to ensure that the water in the mains will remain clear.Īll care is taken to minimize any potential impact on water quality. The program will provide an opportunity to check the condition of the valve box, as well as all aspects of valve operation.ĭuring this program, crews will exercise the valves by operating the valve through a full cycle and returning it to its normal position. The valves are generally in the street located under small lids covering valve boxes, usually about 6 inches in diameter. ![]() The valves provide a means of isolating small lengths of main in the event of a necessary shut down for emergencies or maintenance. The American Water Works Association recommends operation of main line valves periodically to prevent build-up of deposits which may render the valve inoperable.Ī main line valve is a valve which is installed at certain points in the water main system, usually at an intersection where the main may run in different directions or where access needs to be controlled remotely as with a fire hydrant. ![]() The purpose of the program is to exercise main line valves throughout the distribution system to assure reliable operation and maintain water quality. The Department of Public Works conducts water valve maintenance throughout the town. Chemical additives with directions for removing either free chlorine or chloramines from water for use in fish tanks or ponds are available at pet/fish supply stores. Please note: If you have an aquarium or pond always test the water you add to your aquatic environment to be sure it is free of any chlorine before adding fish or other animals. Remember - drinking water has a shelf life! Change out the water in your refrigerated container weekly. This will enable the chlorine to dissipate thus reducing the chlorine taste. If you are especially sensitive to the taste and odor of chlorine, try keeping an open container of drinking water in your refrigerator. You may notice a chlorine taste and odor in your drinking water while free chlorine is utilized. Depending on your location within the distribution system and usage patterns, it could take up to a week for your drinking water to transition from combined to free chlorine at the beginning of April, or from free chlorine to combined chlorine at the beginning of July. Fairfax Water will use free chlorine as the primary disinfectant from April through July. Free chlorine is somewhat more volatile than combined, providing exceptional availability to react with sediments suspended during flushing. During the spring flushing program, chlorine is added in an uncombined state, commonly referred to as free chlorine. Throughout the year, chloramines, or combined chlorine, is added to the water as the primary disinfectant. Running your cold water for a few moments should help clear the line.ĭuring this period of time, a slight change is made in the water treatment process to facilitate an effective flushing program. These conditions are not harmful and should be of very short duration. We do this to maintain the high quality of water in our distribution system.įlushing may result in some temporary discoloration and the presence of sediment in your water. Each spring, the Town of Herndon flushes its water mains by opening fire hydrants and allowing them to flow freely for a short period of time. ![]()
