Ez Flow Septic System

The Infiltrator-EZflow septic system is designed to increase infiltrative performance. It eliminates fines and reduces compaction and embedment that are associated with crushed stones. EZflow products have been certified by IAPMO as well as the ICC-ES PMG Listing Program. The Infiltrator EZflow septic systems are an environmentally friendly alternative to traditional stone drainfields and pipe drainfields. They use a modular engineered geosynthetic gravel design. Gravelless EZflow is designed to enhance drainfield performance by removing fines and reducing compaction as well as embedment that are associated with stone. Pre-assembled units include a 3” or 4” perforated drainpipe, surrounded with aggregate and held in position by durable, high-strength netting.

Benefits:

Bundles are easy to put together, which saves money on heavy machinery and labor.

Modular construction permits configurations that match trench dimensions for most systems shapes and sizes.

  1. Engineered to maximize storage and absorption efficiency
  2. The ability to contour on slopes and around trees or landscaping
  3. This lightweight system is ideal for repairs and tight job sites
  4. It is easy to hand-carry into place, reducing labor time and effort
  5. With simple snap, inner couplers, you can lengthen your items to 5′ and 10′.
  6. Eliminating stones makes cleanup easier
  7. Made from recycled materials and not from a natural resource.
  8. There are many configurations and diameters available to suit the needs of any professional installing.
  9. Approved in many jurisdictions, with an improved efficiency rating, which reduces drainfield size
  10. Backed by the industry leader in onsite wastewater

Drainfields Ez-Flow

Since EZ-Flow was invented, it has been in use for ten years. The disadvantage of a stone-and-pipe drain field is its inability to collect water. 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.

To install the conventional component, first trenches are dug. Each trench must be dug to the same level at the bottom so that the effluent is distributed evenly within the cell. Most trenches are dug at the exact same elevation. Some trenches, however, are dug at different heights due to a shallow limiting factor or a sloped contour. The EZ-Flows are installed in the trench as the trench is dug. Each trench has two observation wells that can be used for monitoring. The governing authority inspects the trenches before they are filled. Finally, the trench can be backfilled.

The EZ-Flow drainfield size depends on how many gallons per day a residence/business produces and the soil loading rate. 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.

FAQ’s

What are the best places to find local installation codes, system designs, and technical questions?

Local codes govern many installation options and requirements. If you have any questions, please contact your local health department and follow their instructions.

What is the maximum size of the leach field that can be reduced when I install Ezflow?

Each local health department determines the system sizing. The system size is usually calculated using a combination soil type and wastewater volume (normally based on the number of bedrooms). Health departments usually approve sizing cuts of 25 to 50% when EZflow has been specified. For details in your area, check your local health codes.

Can Ezflow be installed under 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. For design and installation instructions, contact Infiltrator Water Technologies’ Technical Services team.
