City crews are still working to replace a broken 36" pipeline that caused some residents to be without water.
The pipeline broke sometime Wednesday evening near 32nd Street North and North Harvard Avenue.
They don't expect to be finished until Friday.
The City of Tulsa's Water Distribution Mainline Manager, Blaine Parnell, says the pipeline was about 70 years old, which caused it to burst.
He says the combination of the soil expanding and contrasting could also have added to the water main break.
Parnell says the city's old infrastructure is a problem the city encounters often. Some of the pipelines were installed in the 1920s.
Despite the aging infrastructure, Parnell says the city hasn't seen nearly as many water main breaks as last year.
Since January, there have been 327 waterline breaks, compared to about 800 last year.
Parnell says the city tries to replace old pipelines every year, but despite its efforts, he predicts more breaks in the future.
