CDC designs custom built centralizers to keep the pipe in the center of the well bore during installation of gravel packs and plugs. This has been proven to extend the life and effectiveness of the well.

All CDC rigs have the capability to drill vertical geothermal wells for heating systems and casson hole drilling for construction projects.

Full Lifecycle Project Management and System Design

CDC designs and installs state of the art collection systems that place the main header outside the limits of waste to eliminate settling. The laterals run vertically to the LFG wells either below or above the liner so settling is not an issue. CDC incorporates equalization headers and knock-out tanks in our design to minimize vacuum loss in the system. This design allows you to isolate select portions of the collection system for maintenance without interrupting the rest of the system.

CDC designs and installs custom built knock-out tanks, complete with pump and 5 micron filtration.

CDC also custom builds and installs a patented boot system “Adaptive Coupling and Method” that allows the landfill to settle while maintaining an airtight seal between liner and any penetration through the liner. A variation of this boot system provides the capability to install low cost odor control wells in uncapped areas of the landfill.

CDC designs custom built leachate injection wells for the enhancement of methane production in dry areas of the landfill.

All safety equipment is supplied to insure a safe environment during all phases of the work performed.
