Two pipes were being run over land Thursday from a leaking sewer main in Lexington's Hamburg area to a different sewer system.
That would solve a problem that has existed since the leak was discovered Monday: Leaking sewage was being pumped into smaller sewer lines, where it flowed back to the North Elkhorn Pump Station, and was put back into the leaking line.
But there still was no word on when the line will be fixed. Officials say they are waiting on a custom-made stainless steel part that will be slipped inside the leaking main.
When the same main broke a year ago, it took two weeks to repair, said Mark York, a spokesman for the city's Division of Water Quality. That leak was less noticeable because the spilled sewage was diverted to a nearby manhole.
Never miss a local story.
In the current leak, sewage was spurting from the ground near Star Shoot Parkway and Flying Ebony Drive, then flowing downhill toward an unnamed tributary of Bryan Station Creek.
By Thursday, a trench had been built to carry the sewage to a spot where the tributary was dammed, and then into a sewage line.
The small trickle below the dam appeared to be clear water.
The leaking line, called a force main, carries about 2,000 gallons a minute. An estimated 300 to 500 gallons a minute has been leaking.
When the needed part arrives, the repair will be done at night when the flow is about 1,000 gallons a minute, York said. Sewage will be stored in a makeshift reservoir during the repair, which is expected to take about nine hours.
