Easy Flow Septic

The Infiltrator EZflow septic system replaces traditional stone and pipe drainfields with a modular engineered geosynthetic gravel design. Gravelless EZflow is designed to enhance drainfield performance by reducing compaction and embedment as well as eliminating fines. Pre-assembled units include a 3” or 4” perforated drainpipe, surrounded with aggregate and held in position by durable, high-strength netting.

The Infiltrator EZflow septic system is an environmentally friendly replacement to traditional stone and pipe drain fields using an engineered geosynthetic.Infiltrator EZflow septic systems are designed to improve infiltrative performance by eliminating fines and reducing compaction and embedment associated with crushed stone. EZflow products have been certified by IAPMO as well as the ICC-ES PMG Listing Program.

EZ-Flow Drainfields

ez-flo1EZ-Flow has been around for ten years. The disadvantage of a stone-and-pipe drain field is its incontinence. Stone carries a limestone dust. Although the stone is cleaned before installation, it doesn’t get rid of all dust. Any dust that remains on the stone is washed into soil to prevent soil clogging. This can reduce the life expectancy of a septic tank. This disadvantage was overcome by EZ-Flows.

The EZ-Flow drainfield size depends on how many gallons per day a residence or business produces and how much soil is being loaded. These two factors determine how large the EZ-Flow drainfield must be. A drainfield of 900 square feet is required for a three-bedroom home with a soil test at a loading rate of 0.5. Each EZ-Flow is 50 square feet. This example requires 18 individual EZFlows. EZ-Flows have one drawback: they take up more space than a pipe drainfield and stone.

Ezflow’s Specifications For Maximum And Minimum System Coverage

Infiltrator Water Technologies recommends that EZflow be covered with a minimum 12 inch of compacted material. In a trench system, the maximum allowable cover for EZflow is 96 inches. Maximum coverage in bed systems is 48 inches. For specific requirements, check with your local health code.

Ezflow Can Be Installed Underneath A Driveway Or Paved Surface

Septic leach fields cannot be installed on impervious surfaces like driveways, according to most health codes. The reason is that the soil can be compressed by the pressure of the surface, which can cause a decrease in its ability to filter effluent (wastewater) from the soil. For the exact codes applicable to your area, check with your local health department.

You Can Drive Over Ez Drain

EZflow drainage systems can withstand wheel loading of one pass and light vehicle loads up to 16,000 lbs each axle, provided that the product is installed in a trench with 12 inches of compacted soil placed over the bundles.

Deep Should Ez Flow Be

6″EZflow should be covered with at least 6 inches of soil. EZflow must be buried at least 6 inches deep. The disadvantage of a stone or pipe drain field is that it can be difficult to maintain. Stone carries a limestone dust.
