City Crews Repair Line After Creek Slope Failure Results in Sewer Overflow
The City of Carrollton Public Works Department repaired a 12-inch sanitary sewer line on Monday, November 19 after the break, caused by creek bank failure, discharged roughly 151,000 gallons of wastewater into the Hutton Branch Creek.
Crews were called to the area behind the 2700 block of Winding Creek Drive at 11 a.m. and were able to repair the line, vacuum up the spill, and treat the affected area with a neutralizing/deodorizing agent. All work was completed by 6:30 p.m. the same day. Staff has begun the process of stabilizing the creek bank with shot rock, a rubble that is commonly used to armor shorelines and streambeds, in order to prevent future failure or significant sloughing.
Carrollton Environmental Services staff will continue to monitor the site to ensure environmental safety and water quality. No impacts to drinking water are anticipated. The Carrollton Engineering Department will evaluate the line in this area for possible replacement.
The Texas Commission on Environmental Quality (TCEQ) regulations (30TAC 319) require that municipalities report wastewater collection system overflows to the local media and the County Judge when overflows exceed 100,000 gallons. The City of Carrollton has been working closely with TCEQ to fully resolve the overflow issue.
Creek bank failures are common causes of damage to wastewater lines. The large amount of pressure on the pipes ultimately causes the line to break and overflow. As soon as the break was discovered, Carrollton staff mobilized to stop the overflow and stabilize the failing area. Equipment and personnel from multiple departments worked to resolve the issue, prevent further harm, and maintain environmental safety for the surrounding Carrollton community.
