Lemna Environmental Technologies (LET) was founded over 30 years ago with the vision of developing simple, innovative and sustainable wastewater treatment solutions for municipal and industrial clients. Starting with a unique, patented, duckweed process, from which the name Lemna is derived, LET has continued to develop processes and products that enable clients to protect their water resources now and for the future. With over 300 installations currently operating, LET’s expertise encompasses all aspects of wastewater project development, from conceptual design and product supply to final commissioning and ongoing customer support.

Currently, LET offers innovative designs and products ranging from simple, facultative lagoons to state-of-the-art, aerated lagoon systems capable of meeting the most stringent effluent requirements. Over the years, we have expanded our design capabilities and product line to help clients effectively meet the challenges of more stringent effluent limits for BOD, TSS and ammonia and to address problems of odor control, heat retention and gas collection.

With new ownership in place as of November 2014, a new office location, and an updated production facility, LET is poised to expand its reach further into the wastewater industry. Our full-time staff of environmental engineers and state-of-the-art design facility allows us to offer a variety of technical solutions tailored to fit our clients’ specific needs.
