Little Elm public works completes Winfield Farms manhole replacement project estimated at $1.9 million

Jason Shroyer, Little Elm director of public works, told the council that the Winfield Farms manhole replacement project — awarded to Wilco Underground for a little over $1,900,000 — is complete and that only punch‑list items and cleanup remain.

Shroyer said the town identified 20 corroded manholes at end‑of‑line locations where flows and corrosive conditions had degraded structures. Ten manholes were fully replaced using polymer concrete designed for a long service life; eight were rehabilitated by inserting fiberglass‑reinforced plastic liners that are expanded and cured in place; and two were epoxy‑coated. The polymer concrete replacements were described as expected to last 50-plus years; Shroyer told the council the lining and epoxy treatments should provide roughly 20 additional years of service.

Shroyer said the project’s biggest challenge was congested rights‑of‑way and existing site conditions that slowed work and required lane closures at times. He also noted temporary odor and gas when sanitary manholes were opened for extended periods during construction. He thanked residents for patience while crews completed construction.

Council members asked about expected lifespans after the rehabilitation; Shroyer answered that the lining and epoxy treatments “say, 20 years. So you should get 20 more years once you perform that work.” Shroyer said Wilco Underground was the selected contractor and that the town used an engineering consultant to inventory, classify and prepare plans prior to bidding.

There was no council action required for this informational item; staff closed by saying the remaining work is a punch list and cleanup in the area.
