Horizontal landfill gas collection systems help landfill operators capture gas earlier during active filling, before vertical wells can be installed. This SWANA Applied Research Foundation report explains how these systems can reduce odors, control surface emissions, and support methane reduction when properly designed and integrated into the broader gas collection strategy.
The report emphasizes that horizontal collectors are most effective when tailored to site conditions, coordinated with fill sequencing, and designed with strong liquid management. Condensate and leachate can reduce system performance, so proper grading, drainage features, accessible removal points, and ongoing monitoring are essential. While not a replacement for permanent vertical wells, horizontal collectors offer a practical, flexible tool for improving landfill gas control during active landfill development.
