Connecticut YardFilter Products

The Eljen YardFilter is a wastewater dispersal and disposal technology that applies clarified effluent to the native soil through a proprietary filtering process.

Eljen's CT Exclusive YardFilter Design Provides More Effective Leaching Area In Less Space

  • Superior rating for Pressure & Gravity systems
  • Requires a much smaller installation area
  • No special tools or cover fabric required
  • Made in the USA from recycled materials
  • Comes already assembled- factory installed distribution pipe, no drilling or cover fabric required
  • No stone required
  • Less site disruption or damage to landscape
  • Light weight- hand carry into position

When your installation requires more performance in less space, the Eljen YardFilter Wastewater Leaching System delivers.  The unique design of the YardFilter System provides a two-stage Bio-Matt™ pre-treatment process that increases the soil’s ability to accept the effluent, resulting in a superior leaching system in a smaller footprint.

How the YardFilter System Works

The perforated Support Distribution Pipe is centered within the YardFilter and provides internal distribution of septic tank effluent while securing the Filter Support Modules.
The Filter Support Modules filter septic tank effluent and act as individual 3D Mini-Trenches™ within the system's footprint. Each module consists of a cuspated core surrounded by Bio-Matt™ geotextile fabric. The YardFilter' unique design increases the available surface area within each module. This is known as Infiltrative Surface Optimization (ISO) and provides a system surface area that greatly exceeds that of the Filter Support Module, a traditional gravel trench or that of gravel replacement technology.
Open air channels within the Filter Support Modules support and promote fixed aerobic bacterial growth on the Bio-Matt™ geotextile fabric interface.
Septic tank effluent migrates through the Filter Support Modules and into the Specified Sand layer which surrounds each YardFilter unit. The Filter Support Module clarifies septic tank effluent and assists in its delivery to the Specified Sand. This process promotes unsaturated flow in the Specified Sand and native soils while maintaining the native soil's structure, long term acceptance rate, and its ability to effectively absorb the clarified effluent.
The Specified Sand layer also protects the native soil from compaction, helps maintain existing pore spaces within the native soil column, and preserves the native soil's natural infiltration capacity which is critical for long-term performance.

Lightweight- Easy Install

Note: The featured installation is generic and not representative of each county or local code, but is a general overview for system installation. Please consult your local regulations for proper sizing and construction requirements.

INSTALLATION

Please refer to the Design and Installation Manual for more specific installation steps.

  1. Excavate trench and place first layer of ASTM C33 Specified Sand
  2. Make sure sand is level and stabilized
  3. Install units by connecting the 4″ Support Distribution Pipes
  4. Cap the 4″ Support Distribution Pipe at the end of each row and begin feathering in Specified Sand
  5. Continue back filling, making sure to work the Specified Sand in between each module
  6. Finish back filling with the required amount of Specified Sand (refer to manual) on either side of the units and a minimum of 1″ above
  7. Finish by covering with top soil and seeding to protect from erosion
