Xylem’s Revolutionary Leopold Type 360 Underdrain Features Innovative Backwashing Capability
Xylem now offers the Leopold Type 360 underdrain, a bolt down underdrain system for greenfield projects and water treatment filtration rehabilitation projects. The underdrain system has an innovative design concept where backwash water flows in a 360-degree pattern, increasing efficiency by up to 20%.
An Underdrain Like No Other
Matt Shoemaker, North American Sales Manager for Leopold -- A Xylem Brand, talks through the features of the Type 360 Underdrain, a bolt-down system with a design that allows for longer filter runs, higher efficiency, less backwash water, and extended media life. With a flow concept that avoids dead zones and patented self-cleaning capabilities, the Type 360 is easy to own and operate. Get a close look and hear more about its unique properties in this video.

Filter Technology Saves Colorado Plant 50,000 GPD
Combined with the installation of the new filter media and wash troughs, this particular type of underdrain and media retainer brought the water treatment plant’s operations up to speed.
Retrofit Significantly Reduces Backwash Cycle Interval, Duration And Water Use For Georgia Utility
The North Columbus Resource Facility recently completed a $12-million replacement of its settled water filtration, removing the existing Wheeler filters, their three-part media and 10-inch poured concrete underdrains, which were no longer efficient.
Bioloop Retrofit Reduces Energy Consumption By 43 Percent
When a broken shaft caused a malfunction in one of the brush aerators at the village of Liberty, NY, WWTP, the village worked with its engineers to develop a plan for repair and upgrade.
Oxelia: An Ozone-Enhanced Biologically Active Filtration System
Xylem’s Leopold Oxelia is designed for municipal wastewater treatment. The ozone-enhanced biologically active filtration system and multi-barrier solution combines ozone, filtration and analytical instrumentation to deliver optimal wastewater treatment for water reuse and discharge into sensitive waters.
Howard County, Maryland Sets The Pace In Restoring Chesapeake Bay Ecosystem
Howard County, Maryland, Bureau of Utilities recently completed the $92-million Addition No. 7 project at the Little Patuxent Water Reclamation Plant (LPWRP) to improve the quality of the plant’s effluent discharge and to reduce harmful nutrients reaching Chesapeake Bay. The project’s various increments took over five years to complete and incorporated innovative design solutions and state-of-the-art technologies for denitrification, aeration and disinfection. The project presents a model for Maryland’s 66 largest wastewater treatment plants and possibly procurement of municipal facilities elsewhere facing increasingly stringent regulatory changes.
