San Angelo, TX
Gulf Coast Underground (GCU) completed rehabilitation of sanitary sewer infrastructure at Goodfellow Air Force Base in San Angelo, TX, focused on improving reliability near student housing and dormitory areas. The project began with a detailed CCTV investigation of the 6″ gravity mains serving the area, followed by technical recommendations that informed a formal change order to expand the scope. The final work plan included a mix of trenchless and open-cut methods tailored to site conditions and pipeline failures identified during inspection.
GCU installed over 2,000 linear feet of 8″ and 10″ cured-in-place pipe (CIPP), along with 200 linear feet of pipe bursting to upsize or replace failed 6″ segments. Six lateral T-liners were installed to restore service connections without excavation. Prior to lining, robotic cutters were used to eliminate intrusions and prepare the host pipe for optimal liner installation. Additional preparatory work included thorough flushing, bypass setup, and access coordination for tight utility corridors.
Work was executed using GCU’s full fleet of specialized equipment, including CCTV vans, combo vac/jetter units, boiler trucks, refrigerated trailers, and support vehicles—all supplied through GCU’s in-house wet-out facility. Despite severe winter weather conditions, the project remained on schedule and within budget. Crews followed all site access procedures, including background checks and escort protocols, and adjusted daily to base activity schedules. Daily safety briefings and QA/QC tracking were implemented to meet military compliance requirements. Close coordination with on-site representatives ensured the project was completed safely, efficiently, and with minimal to base operations. This effort highlights GCU’s ability to perform high-quality trenchless rehabilitation within secure and logistically sensitive environments.
