Do you trust your local government to protect water quality during city construction projects?

A contractor working on a city project struck a wastewater pipeline in the 700 block of E. Valley Ridge Boulevard in Lewisville on Thursday around 11:30 a.m. At least 100,000 gallons of wastewater breached the work site and discharged for approximately five minutes.

Why it matters

The spill reached Prairie Creek, a waterway that feeds toward the Elm Fork of the Trinity River, so containment mattered for downstream water quality. Officials believe the city's drinking water has not been affected, but the final spillage estimate is still being calculated.

At least 100,000 gallons of wastewater were released in about five minutes after the pipeline was struck, according to preliminary city information. The final volume that reached Prairie Creek has not yet been determined.

The players

Texas Commission on Environmental Quality

The state environmental regulator that Lewisville has notified and will send follow-up information to, including final spillage estimates and corrective actions.

The details

Wastewater was initially contained to the excavation area before breaching the work site. The contractor built an improvised berm within Prairie Creek that stopped further movement toward the Elm Fork of the Trinity River, and contained wastewater is being pumped out and conveyed to the wastewater treatment plant.

Thursday, around 11:30 a.m.: Contractor hit the wastewater pipeline at the 700 block of E. Valley Ridge Boulevard.
Thursday, around 4:30 p.m.: At least 100,000 gallons of wastewater had been released at the work site.

Market Landscape

Lewisville's notification to the Texas Commission on Environmental Quality places the incident within the state's wastewater discharge reporting process. The follow-up submission will document the final spillage estimate and any corrective actions taken.

Residents near the discharge were urged to take precautions, and private well owners within one-half mile were advised on water safety. Officials say the city's drinking water has not been affected.

The takeaway

Infrastructure contractors working near buried utilities can trigger releases that spread quickly, so verifying line locations before excavation is a basic safeguard. Residents near a spill should follow local advisories on well water and avoid contact with affected waterways until officials confirm they are safe.

What happens next

Lewisville will submit follow-up information to the Texas Commission on Environmental Quality, including the final estimated spillage and any corrective actions.
