Mansfield crews are working to repair a sewer line break that has released 1.8 million gallons of sewage into Walnut Creek in the northwestern part of the city.
A 30-inch sewer line ruptured causing the drainage banks that feed into Walnut Creek, down stream of North Street, to give way. City staff believe extended rains including precipitation Oct. 31 caused soil saturation, lessening the sewer main’s support, which resulted in a break.
Crews have dammed the banks of the swell and pumped sewage back into the sewer system.
A by-pass solution will be operational by noon today.

The rupture was noticed during a routine inspection at 11 a.m. Tuesday.
The spillage was contained to the creek and officials are asking people to avoid the creek.
City staff has begun work on a permanent repair, which may take weeks, but the by-pass solution of pumping the sewage through an alternate route should suffice.
“There’s the response phase and action phase and we’re almost through with that,” Jeff Price, assistant utilities director, said. “We’re into the phase of designing a permanent solution for the repair.”
A portion of North Street from Van Worth Street to Newt Patterson Road will remain closed while the city performs the permanent repair.
Price said staff is still evaluating the condition of Walnut Creek and a remediation plan will be developed. He added the Creekside Cleanup and Cookout event scheduled for this weekend will be canceled.
