When your installation requires more performance in less space, the Eljen Mantis Wastewater Leaching System delivers.

How the Mantis System Works
The Eljen Mantis Series is a wastewater dispersal and disposal technology that applies clarified effluent to the native soil through a proprietary filtering process. The Mantis protects the native soil’s long term acceptance rate by keeping the biological growth off the native soils and within the Mantis units. The Mantis utilizes 3-D Mini Trenches™ to improve effluent quality, resulting in greater performance, reliability and ease of operation.
