Experimental set-up
- Two test sites on a slope with different orientation (north, south)
- Removal of leachate with plastic suction plates
- Three suction plates installed at four depths on each surface
- Finely adjustable negative pressure using electronic vacuum control
- Automatic control of system integrity through a control function
- Near-surface sampling of the leachate when rewetting
- Central energy supply through a fuel cell
- Installation and commissioning by ecoTech
