Lemna Environmental Technologies (LET) was founded over 40 years ago with the vision of developing simple, innovative and sustainable wastewater treatment solutions. LET has continued to develop innovative technologies that enable municipal and industrial clients to protect water resources now and in 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. As regulatory requirements have become more stringent, LET has expanded our design capabilities and product line in order to help clients more effectively meet the challenges of a tougher regulatory environment. By aggressively focusing on technology development and customer service, we have developed a wide array of products and processes designed to economically meet the needs of our customers. Currently, LET offers innovative designs and technologies ranging from simple, facultative lagoons to state-of-the-art, aerated lagoon systems capable of meeting the most stringent effluent requirements.
