Ez Flow Septic Drain Field System

Infiltrator’s EZflow septic systems have been designed to increase infiltrative performance. They eliminate fines and reduce compaction and embedment that are associated with crushed stones. EZflow products have been certified by IAPMO, ICC-ES PMG Listing Program. The NexGen EZflow septic systems are an environmentally friendly alternative to traditional stone drain fields and pipe drain fields. It uses a modular engineered geosynthetic gravel design. The EZflow system improves drainfield performance by reducing fines, compaction, and embedment that are associated with stone. Pre-Assembled units consist of a 3’’ or 4’’ perforated pipe, surrounded with aggregate and held in position by durable, high-strength netting.

A plastic septic tank is the cheapest. They are lighter than concrete and fiberglass tanks, and therefore easier to install. They are waterproof and resist water corrosion. The average cost of plastic septic tanks is around $1,200

Which Systems Can Ez Flow be Installed in?

EZflow is compatible with almost all septic leach fields and leach beds. EZflow is compatible with any type of pipe and stone. This includes installation in trenches, beds, and elevated mounds. EZflow offers superior treatment capabilities for pressure dosing and serial distribution.

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 surface pressure can cause soil to compact, which can affect the soil’s ability of treating effluent (wastewater). 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 at 1-800-718-2744.

What is Ezflow’s Minimum and Maximum System Coverage Specification?

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 cover for bed systems is 48 inches. For specific requirements, check with your local health codes. These systems can be used either for one residence or a small number of homes.

How long does a septic tank last?

Proper maintenance can last for 30 years, as it is costly to replace a system. Your system will last longer if you take proactive steps to maintain it. Septic tanks can actually last for as much as 30 years.
