COMANCO Advances Innovative Closure System at New River Landfill in Raiford, Florida
Five years after completing Phase I of an innovative landfill closure system, COMANCO returns to the New River Landfill in Raiford, Florida, for Phase II.
Located in Union County in North Central Florida, Raiford is a rural community known for its agriculture and regional history. The New River Landfill serves surrounding counties and plays a critical role in managing regional solid waste. Additionally, the landfill protects the area’s natural resources, including nearby waterways and groundwater systems.
The project builds on an exposed geomembrane cap (EGC) closure system that COMANCO first installed during Phase I in 2020. This design eliminates the need for traditional cover soil and sod while maintaining long-term environmental protection. In areas like Raiford, where soil conservation and efficient land use are important considerations, this approach is particularly beneficial.
As a repeat client, the New River Solid Waste Association once again turned to COMANCO to install critical containment and gas management infrastructure that will support the site’s performance for years to come. The continued partnership underscores COMANCO’s expertise in delivering sustainable solutions that meet both environmental standards and the long-term needs of the communities they serve.
Progress Continues on Phase II
The project progresses under the leadership of Superintendent Jorge Gomez and Leadmen Segundo Alvarez and Lucas Aguilar. Crews are currently installing toe drains, followed with geomembrane liner installation on the slopes.
The project includes approximately 418,859 square feet of 60-mil textured HDPE geomembrane supplied by AGRU, along with landfill gas collection piping supplied by ISCO.
To date, the team has installed:
- 187,578 SF of HDPE geomembrane
- Approximately 1,660 LF of 2-inch pipe
- Approximately 1,116 LF of 6-inch pipe
Crews recently completed one of the project’s two planned sumps and continue advancing liner and piping installation across the site.
A Unique Approach to Landfill Closure
What sets this project apart is its closure design.
Phase II utilizes an exposed geomembrane cap (EGC) system featuring ballast trenches and an 18-inch offset fusion weld configuration. Unlike traditional landfill closure systems that rely on cover soil and vegetation, this design eliminates the need for soil cover and sod while maintaining the containment systems integrity.
The approach offers several advantages, including reduced material requirements, lower long-term maintenance demands, and improved accessibility for inspections. As landfill owners continue exploring innovative closure solutions, exposed geomembrane cap systems are gaining attention for their efficiency and long-term performance.
Having completed Phase I in 2020, COMANCO brings valuable project knowledge and continuity to the second phase of this specialized closure system.
Supporting Long-Term Environmental Protection
Every component installed on this project serves a specific purpose in protecting the surrounding environment.
The geomembrane liner system helps prevent water infiltration into the waste mass. This system reduces leachate generation and supporting the overall performance of the closure system. Toe drains assist with drainage management, while the landfill gas collection piping provides a pathway for controlled gas movement beneath the cap.
Together, these systems create a comprehensive containment solution designed to minimize environmental risk and help safeguard nearby soil and groundwater resources.
Performance and Partnership
Repeat projects reflect trust earned through performance. COMANCO’s continued work at New River Landfill demonstrates the value of experience, quality work, and a commitment to delivering solutions that meet each client’s long-term goals.
As Phase II progresses, the team remains focused on executing every aspect of the project with the attention to detail and safety standards that define The COMANCO Way.
