How many rows of perforations does an 8-10 inch gravel less pipe have?

An 8-10 inch gravel-less pipe typically features two rows of perforations. This design allows for efficient drainage and infiltration of effluent into the surrounding soil while preventing sediment clogging, which can be a concern with traditional gravel and perforated pipe systems. The two rows enhance the surface area available for liquid to exit the pipe, maximizing the system’s performance in distributing water evenly into the surrounding media.

Gravel-less systems are engineered to provide equivalent hydraulic performance to conventional systems but with the added benefits of reduced excavation and less reliance on gravel backfill, simplifying installation and maintenance. This design promotes better aeration and filtration of the effluent as it moves through the soil, ultimately contributing to the overall effectiveness of the on-site sewage facility.
