The water plant will start their annual unidirectional flushing on May 28th, 2019. The flushing will occur Monday through Friday from 9:00 am to 4:00 pm and will continue for two to three months.
We will start on the north side of the city and work our way south. A city-wide announcement will be made once the flushing is completed.
What is Unidirectional flushing? Unidirectional flushing is used to improve and maintain our high-quality drinking water. Sediments and mineral deposits in the pipes can discolor drinking water. The high-speed water flows used in unidirectional flushing is an efficient and cost-effective way to remove sediments and deposits from the pipes and prevent potential water quality issues.
Why does La Vergne flush drinking water pipes? Drinking water pipes are flushed out to maintain water quality. Over time, very fine sediment from mineral deposits and organic matter settle out of the water and accumulate in the bottom of the pipes. While the sediments pose no health risk, they can make the disinfectant in the water less effective. Additionally, sudden changes in the flow of water can disturb these sediments resulting in cloudy, discolored water.
What should customers expect to see? While crews have the hydrants open, passersby may notice water running down the road to a nearby storm drain. At times, the water may be very cloudy or discolored and this is normal.
How will this affect the customers home?
