SD315 WELLHEAD

 

A combined gas/leachate extraction wellhead which allows precise monitoring and flow regulation from each extraction well within a landfill gas system.
It comprises an upper chamber into which the extracted gas flows, cools and forms condensate. A dewatering lance connects the upper chamber to a reservoir at the base of the wellhead from where it can flow back into the well.

The reservoir also acts as a hydraulic seal against the suction vacuum.
A large diameter internal pipe also runs from the top to the bottom chamber into which an AUTOPUMP® can be installed to control the leachate level within the well. The outer sleeve fits over the top of the gas extraction well liner, and depending on the model, can allow up to 2 metres of settlement.

The SD315 can be fitted into a collection system either ‘in-line’ where the gas passes through each wellhead and is continuously dewatered or ‘end-of-line’ connecting individual lines into a Field Regulation Station (FRS). It can be fitted with or without an internal regulation valve.
