Capital Improvement Project

Llano Trunk Rehabilitation Phase 1 LTP to Todd Rd

Estimated Construction Schedule: Slated to begin June, 2025 and is anticipated to be completed November, 2025.
Construction Contract Amount: Pending
Project ID #: 2403

Description: This project will rehabilitate approximately 8,100 linear feet of 66-inch reinforced concrete trunk sewer. The trunk sewer is located adjacent to the Llano Road. The work area extends from north of Todd Road to the City's Laguna Treatment Plant. To rehabilitate the trunk sewer, crews will use a trenchless cured-in-place pipe lining technology. This approach minimizes surface disruption while reinforcing the existing pipe from within. During construction, a temporary above-ground sewage bypass pumping system will operate 24 hours a day. This system will include full backup pumping capacity and three parallel 18-inch bypass lines running about 9,000 feet adjacent to Llano Rd.
