The Mantis M5 Series wastewater dispersal and disposal system from Eljen Corporation applies clarified effluent to the native soil through a filtering process. Each three-dimensional module consists of a cuspated core surrounded by Bio-Mat geotextile fabric. It clarifies septic tank effluent with a two-stage filtration process that protects the native soil’s long-term acceptance rate. Its infiltrative surface optimization technology significantly increases the product’s performance footprint, while mini-trenches provide storage capacity and oxygen transfer zones to boost performance. It comes in lightweight 2- and 3-foot install options. 800/444-1359; www.eljen.com.
