Heavy Rainfall Causes Overflow In Trinity River Authority Wastewater Collection System

March 10, 2016

(ARLINGTON, TEXAS) – A Trinity River Authority wastewater collection system meter station within its Central Regional Wastewater System experienced an overflow on Wednesday, March 9. The meter station is located east of 4592 Fargo Drive, Grand Prairie, Texas. The overflow of wastewater spilled into Mountain Creek, a small tributary that flows into Mountain Creek Reservoir. Recent widespread, heavy rains have inundated the area and hydraulically overloaded the pipeline, which caused the overflow. Rainwater diluted the spill, which helped to minimize its overall effect.

TRA crews are standing by to begin cleanup when the rainfall subsides and the area is accessible.

All wastewater overflows in excess of 100,000 gallons must be reported to TCEQ, the public and other designated public officials. The final estimated quantity of the overflow will be reported to TCEQ.

No public drinking water supplies were threatened or contaminated by this overflow. TRA has notified all required city, county and state officials.
