30-inch sewer main rupture triggers major spill in Grand Prairie, Texas

(UI) — A ruptured 30-inch wastewater force main caused a sanitary sewer overflow in the Trinity River Authority's Central Regional Wastewater System, releasing more than 100,000 gallons of wastewater near Grand Prairie, Texas.

The overflow was discovered at about 2 p.m. on July 4 after the pipeline ruptured near 6321 Mirabella Blvd. Although the mailing address is in Arlington, the Trinity River Authority said the actual spill occurred south of the Arlington city limits in Grand Prairie.

The agency notified the Texas Commission on Environmental Quality, the public and other required officials, as state regulations require for wastewater overflows exceeding 100,000 gallons. A final estimate of the discharge volume will be submitted to the agency.

According to the Trinity River Authority, the overflow has not interrupted wastewater service to customers.

Officials said the wastewater was diluted and that no public drinking water supplies or aquatic life have been affected.

Residents using private drinking water wells within one-half mile of the spill site or other potentially affected areas are advised to use only distilled water or water boiled for at least one minute for drinking, cooking, bathing and brushing teeth. The authority also recommends testing and disinfecting private wells before returning them to normal use.

People served by public water systems should contact their local water provider if they have questions about water quality.

The authority also urged the public to avoid contact with wastewater, contaminated soil and nearby surface water. Anyone who comes into contact with potentially affected areas should bathe and wash clothing thoroughly as soon as possible.
