Crews have closed the emergency gate that was dumping sewage into the Schuylkill River, officials in Reading said Wednesday.
They said the pipe lining has been fixed, and the raw sewage is now going into the waste water treatment plant on Fritz Island.
Crews had been working since Monday night to fix the break.
It was located on the west bank under the Route 422 underpass near Brentwood Drive, just 50 feet from the river.
The pipe is 60 years old.
Officials said the combination of weather conditions within the past month could be to blame for the break.
This is the second time in three years that the piping ruptured.
The city is currently working on a $15 million project to construct a new sewage pipeline.
