Manifolds provide central monitoring and control of multiple landfill gas extraction wells which means that smaller pipes can be fed from the wells together with less trenching as smaller pipes can be installed within a common trench.

They are typically set on concrete bases and protected by the construction of brick or block walls and a protective lid.

Individual inlet control is by Safi ball valves providing superior flow control together with minimal losses. Total flow is controlled by a butterfly valve on the outlet. Self-dewatering of condensate is achieved by having a 1mm in 100mm fall of the manifold body.

They are available as standard from 4 to 12 way but other be-spoke designs are available on request.
