Atmos Energy outlines pipeline replacement through Towne Lake; work will affect park access

Aug 18, 2026

Atmos Energy presented plans to replace an aging trunk line through Towne Lake, replacing roughly 2.5 miles of 6-inch pipe with about 2.65 miles of 12-inch pipe, enabling in-line inspection and increasing capacity; work is expected from late 2026 into spring 2027 and will require temporary closures and some canopy clearing.

The full story

Atmos Energy representatives told the McKinney City Council on Aug. 18 that a trunk-line replacement project (D921212) will run through portions of Towne Park/Towne Lake and nearby corridors, increase pipeline capacity and enable in-line inspection ("pigging"). Josh Raines, senior engineer with Atmos, said, “The purpose of the project is infrastructure renewal.” He told council the work will replace roughly 2.5 miles of 6-inch steel with about 2.65 miles of 12-inch steel, increase inspection capability, and provide additional capacity to serve future growth, including the new amphitheater.
