Infiltrator chambers offer sizing reductions of up to 50%* with equal or better performance.

University laboratory research and extended field evaluation has verified the infiltrative efficiency advantage of the open surface architecture provided by chamber systems over old-fashioned stone and pipe systems. The advantage lies in the absence of solid bodies in the leachfield surface architecture – the matrix of combined gravel, soil and biomat at the infiltrative surface.

University laboratory research and extended field evaluation has verified the infiltrative efficiency advantage of the open surface architecture provided by chamber systems over old-fashioned stone and pipe systems. The advantage lies in the absence of solid bodies in the leachfield surface architecture – the matrix of combined gravel, soil and biomat at the infiltrative surface.

The stones embed into the soil surface and occupy about 60% of the potential infiltrative area. This forces the water to travel through the limited pores in the soil- filled gaps between the stones. An obstructing layer of biomat forms in all leachfields treating septic tank effluent. As the biomat develops, the infiltrative capacity of that remaining soil area is reduced to a point where ponding occurs in the leachfield.

The advantage of the open surface architecture is that the entire area is available for infiltration instead of the 40% remaining area between the stones. The open surface architecture of chambers over old-fashioned stone trenches isexpressed as:

100% open area / 40% open area = 2.5 more infiltration potential.

With an added safety factor, a 50% smaller footprint will provide equal or better infiltration than a stone and pipe trench.

Stone and pipe systems – Less than 50% efficiency In the stone and pipe system, the effective infiltrative area is reduced due to the presence of stone.

Infiltrator chambers – 100% efficiency With Infiltrator chamber systems, the entire area at the bottom of the trench is unobstructed by stone, which means total infiltrative effectiveness.
