What is the first step in landfill cell construction?

The first step in landfill cell construction is the construction of the bottom liner. This phase is critical as the bottom liner serves as the primary barrier to prevent leachate, a liquid that can contain harmful substances, from contaminating the surrounding soil and groundwater.

Establishing the bottom liner involves careful selection and installation of materials that meet regulatory requirements and engineering standards. This process ensures ecological safety and compliance with environmental regulations. Once the bottom liner is securely in place, other components, such as site clearing and gas collection systems, can be addressed in the construction sequence. Final cover placement occurs last, as it's intended to cap the completed landfill once it reaches maximum capacity.

In essence, focusing on the bottom liner first is essential to establish a safe, functional system that effectively manages the waste materials that will be deposited in the landfill.
