What role does a collection manifold play in a landfill gas collection system?

A collection manifold plays a crucial role in a landfill gas collection system by serving as a central gathering point for collected gas. In this system, gas produced from the decomposition of organic waste within the landfill is collected through a network of wells or piping. The manifold collects this gas from various points, allowing for effective transport to a treatment or utilization facility.

By centralizing the collection process, the manifold ensures that the gas can be efficiently monitored, managed, and directed for energy recovery or flaring, thereby reducing odors and greenhouse gas emissions from the landfill. This centralization is key for maximizing the efficiency of gas collection efforts, optimizing performance, and maintaining system integrity.

The other options refer to distinct components and functions within landfill operations but do not pertain to the specific function of the collection manifold. Filters target waste management, leachate distribution pertains to water management, and surface drainage concerns itself with stormwater control, none of which directly relate to the role of the collection manifold in managing landfill gas.
