Efficient, Proven Drainfield Design

Chamber systems are a popular conventional septic option that use plastic arch chambers instead of gravel in the absorption trenches. They're lighter to install, provide strong void space for effluent distribution, and are widely accepted by Arizona counties for Type 4.02 systems.

Chamber Advantages

No gravel hauling — faster, cleaner installation

High void space for good distribution

Widely approved for conventional design

Long service life with proper maintenance

Synthetic Rock Bundles

Infiltrator's EZ Flow system consists of pipe surrounded by expanded polystyrene (EPS) aggregate bundles, held together by netting. This conventional septic option mimics the function of a rock trench but without the heavy hauling of stone. It's extremely flexible, making it great for curved trenches around trees or property lines.

EZ Flow Advantages

No gravel hauling required (clean installation)

Flexible bundles conform to curved trenches

Higher void space than natural stone

Usually qualifies for size reduction (varies by county

Proven Conventional Disposal

Rock trench systems are a time-tested conventional septic design that use perforated pipe surrounded by clean stone in excavated trenches. They're a time-tested, county-accepted method for Type 4.02 systems when soil percolation and setback requirements are met.

Rock Trench Benefits

Widely accepted by Arizona counties

Durable and long-lasting when designed correctly

Familiar to installers and inspectors

Effective where soil and lot size allow
