Nearly 40 Homes in Franklin Hills Just Got Switched to New Water Mains
The two-day cutover on High Road is done — here's what's left before the project wraps.

If you live in Franklin Hills and your water pressure felt a little different during the two-day cutover, now you know why.
Contractors working the High Road Water Line Replacement Phase 2 project spent those two days making the final connections that transferred service from the old water system to the new one. The work disrupted service to a combined nearly 40 homes over those two days. Affected residents had been notified ahead of time.
The switchover was the last big hurdle. All new water mains installed under the project are now in use, and all individual service lines have been transferred to the new mains. The old lines are out of the ground.
The project covers roughly 11,500 linear feet of substandard water lines inside Franklin Hills. The neighborhood was developed in the 1950s as a weekend retreat community, before Flower Mound was incorporated — which gives you a sense of how old those pipes were.
Finishing work is what remains. Crews still need to complete permanent asphalt repairs, site restoration, and final cleanup. If you see someone patching pavement on your street in the coming weeks, that's the final leg, not a new problem.
The total project budget is $4,030,000, funded through utility debt and other sources.
For residents outside the immediate switchover area: driveway access rules are still in effect during active work. Some driveways may be blocked during daytime operations, and the contractor is required to give affected residents one to three days' notice before any driveway restrictions go into place.
