The second water main eruption along Miller Road in six months closed westbound traffic and limited eastbound to a single lanes due to extensive flooding on Sept. 20.
The 48-inch main that ruptured on SW 56th Street near 129th Avenue caused all traffic to be diverted away from the affected area, reported Jennifer L. Messemer, information officer for the Miami-Dade Water and Sewer Department (WSD). A boil-water advisory was not issued.
A WSD crew immediately began working to repair the split and restore normal traffic on the busy east-west Kendall artery.
The first break along Miller Road in the same area also detoured and delayed vehicles at SW 124th Avenue, between May 3 and May 16, before repairs allowed a return to a normal traffic flow.
In both cases, extensive flooding resulted from the breaks with neighboring residents advised they could experience low water pressure.
The Miller Road water main has been explored continually by robotic cameras to determine weakest links in the aging pipeline system, according to WSD.
A report to replace the section where the latest rupture occurred was received only two days before the second break occurred, a spokesperson at Commissioner Joe Martinez’s office said.
The 48-inch line under the median area of the four-lane arterial roadway is a regional transmission main providing water to southwest county areas, Messemer noted.
Area residents were advised to conserve water usage during the repair process, she added, noting that customers could expect water pressure reduction during peak water demand times (morning and evening hours).
