Moss Point, MS
Gulf Coast Underground (GCU) led Phase I of the Moss Point Sanitary Sewer Improvements project, a major rehabilitation initiative aimed at restoring reliability and reducing inflow and infiltration (I&I) throughout the City of Moss Point’s wastewater collection system. The project was part of a broader capital improvement strategy focused on modernizing aging infrastructure, addressing long-term capacity concerns, and improving system efficiency in key service basins.
A central component of the project was the full rehabilitation of two critical pump stations serving large sections of the city’s sewer network. Each site received new submersible pumps, piping, valves, and electrical systems, including SCADA-ready control panels and permanent backup power generation. Wet well tops were reconstructed with new precast elements, and structural modifications were made to improve accessibility and long-term performance. GCU carefully sequenced bypass pumping, demolition, and reinstallation to maintain uninterrupted flow throughout construction.
Beyond the pump station work, the project included over 26,000 linear feet of cured-in-place pipe (CIPP) rehabilitation across 8″, 10″, and 12″ gravity mains. More than 800 vertical feet of manholes were structurally rehabilitated, and over 25 point repairs were completed across a range of pipe sizes and installation depths. GCU also installed 9,500 linear feet of new force main using a mix of open cut, jack & bore, and directional drilling methods to navigate congested corridors, road crossings, and utility conflicts. More than 75,000 linear feet of sewer main were cleaned and televised to assess conditions and confirm post-installation quality.
Construction was carried out in active residential and commercial areas, requiring multi-phase traffic control, site-specific access planning, and ongoing coordination with city staff and engineering teams. Work was completed under live flow conditions, with GCU managing multiple crews across various work zones to maintain progress and minimize disruption to the public. Crews adhered to a strict schedule and managed material delivery, staging, and environmental compliance throughout the project duration.
The project was delivered within the original contract value of $4.01 million and completed within the agreed schedule. GCU’s performance on the Moss Point Phase I project highlights the company’s ability to deliver complex, high-impact utility rehabilitation projects across multiple locations, all while maintaining precision, responsiveness, and a strong commitment to quality.
