Fayetteville Public Utilities has recently installed devices at seven locations to automatically flush local fire hydrants to assist with the utility’s routine inspection for water quality.
“The flushing devices have been installed at dead-end lines,” said Fayetteville Public Utilities CEO and General Manager Britt Dye. “The purpose of flushing the water lines is to maintain the quality of our water supply where stationary water has the potential to cause quality issues. Flushing the lines keeps our water quality and chlorine residual up to meet water quality standards.
“Until now, FPU employees have manually flushed the water lines in these areas to keep our water supply in check. The automatic flushing system will increase the frequency of when the lines are flushed and will insure water quality throughout the system.”
Each of these devices is programmed to operate at midnight on its scheduled night of the week. Some hydrants will operate for five minutes while others will operate for up to 25 minutes to flush the water line.
There are other advantages to installing the automatic hydrant flushing devices. FPU says that the automatic flushing system will reduce labor costs associated with the flushing process. Previously, lines were flushed once or twice a month depending on the area. Now lines will be flushed on a weekly schedule.
Water lines and flushing devices will continue to be inspected by FPU employees monthly to guarantee proper operation of the devices and to test water quality.
In addition, when FPU water lines are flushed, it usually decreases water pressure in the area. Automatic flushing at midnight will reduce this inconvenience to most customers.
