Gas Discharging Systems

Gas Discharging Systems

Drainage geocomposites are commonly utilized in combination of geomembranes to conform state of theart lining systems required for nowadays designs of liquid containment structures.

When a reservoir is built over an organic layer of soil, or when other factors are present which promote the production of subsoil gas, the liner system of the structure has to be capable of discharging those gases from beneath the impermeable geomembrane layer to the atmosphere.

The gas discharging system consists of a series of drainage geocomposite strips installed from the bottom to the top of the reservoir’s surface, beneath the impermeable geomembrane layer. The drainage geocomposite collects and conducts gas produced in the subsoil to the higher parts of the reservoir, where it is discharged to the atmosphere through discharging pipes located at the top of the reservoir’s slopes.
