Sycamore Creek Sanitary Sewer Interceptor – City of Fort Worth

City of Fort Worth Texas

The City of Fort Worth selected Lockwood, Andrews & Newnam, Inc. (LAN) to provide rehabilitation design and route analysis for their Sycamore Creek Sanitary Sewer Interceptor. The project is part of the City’s Interceptor Condition Assessment Program (ICAP), where all of the City’s sewer interceptors have been assessed for condition and remaining life to prioritize rehabilitation needs.

LAN was selected to evaluate rehabilitation alternatives for 10 separate segments of the Sycamore Creek Interceptor. The design consists of both open cut replacement and cured-in-place rehabilitation for roughly 6,000 LF of 27- to 66-inch unlined concrete pipe within the greater 25,000+ LF system. Design challenges included extensive coordination for bypass piping and construction access through several City parks (Sycamore and Cobb Park), the Sycamore Creek Golf Course, railroad crossings, TxDOT roadway crossings, and an abandoned landfill.

While developing the rehabilitation design, efforts also included route analysis for a future 72-inch diameter relief interceptor totaling more than 20,000 LF. Four separate routes were evaluated to consider constructability, maintainability, stakeholder impacts, and cost. Design/Construction phasing and potential interaction with rehabilitation requirements were considered through evaluations in determining the optimal alignment for future development.
