Lemna Environmental Technologies

What Lemna Environmental Technologies does

Lemna Environmental Technologies, Inc. (LET) is a privately held wastewater treatment solutions provider founded in 1983 and headquartered in Vadnais Heights, Minnesota. The company designs, engineers, and delivers turnkey treatment systems for municipal and industrial clients, with a specialization in lagoon-based processes. Its primary customer base consists of small-to-mid-sized municipalities seeking cost-effective compliance solutions and industrial operators across the agricultural, chemical, energy, manufacturing, and food and beverage sectors, with a secondary focus on small communities operating under budget constraints.

The company's offering is built around the proprietary LemTec™ technology platform, an integrated portfolio of treatment processes including aeration, biological treatment, hydraulic baffling, moving bed bioreactor (MBBR), partial-mix facultative treatment, phosphorus removal, polishing reactors, and recirculating sand filters, complemented by modular cover systems (modular insulated, segmented floating, and gas collection). These components can be deployed as standalone upgrades or configured into full treatment trains, enabling the firm to address BOD, TSS, ammonia, total nitrogen, phosphorus, odor, algae, heat retention, sludge, and biogas capture challenges. The company claims achievable year-round effluent limits as low as 10 mg/L BOD, 10 mg/L TSS, and 2 mg/L NH3-N.

LET generates revenue through two streams: hardware sales of LemTec™ branded products and professional services covering design, engineering, project management, and installation under a concept-to-commission delivery model. Go-to-market is enterprise field sales with quote-based pricing initiated through a "Request Proposal" call-to-action on the website. The firm maintains an 11–50 employee footprint, primarily serves a domestic U.S. market, and operates without disclosed external funding, M&A activity, or parent company ownership, with Lemna Ownership Services representing a recent expansion toward recurring service engagement.
