On Tuesday, November 17, 2015, the Angelina & Neches River Authority (ANRA) experienced a catastrophic failure of the sanitary sewer collection system at its North Angelina County Regional Wastewater Facility (NACRWF) located at 996 Edgewood Drive, Lufkin, TX. A manhole on the main trunk line collapsed at the entrance of the wastewater treatment facility resulting from localized flooding during the thunderstorms that occurred on November 17th.
The collapsed manhole caused a complete blockage of the trunk line delivering sewage to the wastewater treatment plant and resulted in the unauthorized discharge of approximately 300,000 gallons of rainwater and raw domestic sewage. The event started at approximately 10:15 a.m. on November 17, 2015. Temporary repairs were completed at approximately 8:30 p.m. that same day. Permanent repair activities are currently underway to ensure this type of wastewater spill does not occur in the future at this location.
The discharge path from the location of the manhole collapse is to an unnamed tributary; then to Mill Creek; then to Paper Mill Creek; then to the Angelina River and ultimately to the Sam Rayburn Reservoir. After factoring in the volume of rainfall and localized flooding, containment/clean‐up of the unauthorized discharge was not possible. ANRA anticipates impact to public health and the environment to be minimal. However, as a Precautionary Measure, the Texas Commission on Environmental Quality (TCEQ) requires the following Precautionary Statement:
ANRA has notified the TCEQ of the spill. This notification should also serve as notice to local governmental officials, local media, and the community at large.
If you have questions regarding this matter you may contact Kelley Holcomb, General Manager, Angelina & Neches River Authority at (936) 632‐7795 or (800) 282‐5634.
If you wish to contact TCEQ directly, you may call 409‐898‐3838.
