Installation

Technical Specifications of Multriwell:

Vertical Multriwell drains (Type V)

Flexible drains, installed in a fine-mesh grid (3x3, 4x4, 4x5 m depending on the expected gas production and specific client requirements) in the waste body, reaching depths of up to 20 meters. These drains are pushed in the waste and perforate the waste body, thus stimulating biological degradation.

Horizontal Multriwell drains (Type H)

The vertical drains are all interconnected with Multriwell type H drains. These are specifically developed drain mats that are installed directly on the surface of the landfill. The horizontal drains ensure a fluent gas flow from the vertical drains, onwards to the collection and transportation system.

Manifolds

Integrated distribution stations that allow precise control of methane concentration. Only a discreet manhole cover is visible in the landscape.

Capping Construction

Optional use of a Trisoplast® or PE cover layer for sealing and capturing the collected landfill gas.

Installation Configurations

Suitable for both single-layer and multi-layer installations, during or after waste deposition.
