A WINNIPEG ENTREPRENEUR IS DEPLOYING A MOBILE BARGE-BASED REMEDIATION PLATFORM TO PULL PHOSPHORUS FROM EUTROPHIC LAKES — AND TURN POLLUTION INTO A PREMIUM AGRICULTURAL PRODUCT.
Excess phosphorus in freshwater lakes is one of the most persistent and costly environmental challenges facing municipalities and water managers across Canada and around the world. Nutrient runoff from agricultural and urban sources accumulates in lakes over time, fueling toxic algae blooms, degrading water quality, and threatening the communities and ecosystems that depend on clean water. Conventional treatment approaches — chemical dosing, algaecide, mechanical harvesting — are costly, disruptive, and rarely address the root cause.
Lakewater Nutrient Capture Ltd. (LWNC) is building a better answer — and the entrepreneur behind it has spent a lifetime solving hard problems.
A Builder from the Ground Up
Weber grew up on a family acreage in Manitoba, where practical hard work was a way of life from an early age. After completing general studies, he joined a consulting engineering firm and rose from junior technician to head of the CAD department. Over his career he developed a broadworking knowledge across the common engineering disciplines and architecture, and became the go-to person for getting complex, difficult projects back on track — a reputation built on unconventional thinking and relentless follow-through.
A 2023 feasibility study for a large industrial project ultimately did not move forward — but the extensive research it demanded led Weber to identify a high-performance engineered material with remarkable phosphorus capture properties. He immediately recognized its potential to be commercialized into a service that could address one of Canada’s most widespread and underserved environmental problems.
The Technology: From Pollutant to Product
At the heart of the LWNC system is a motorized barge carrying an array of canister assemblies loaded with a proprietary sorbent material developed specifically for selective phosphorus capture from lake water. As the barge travels in a methodical grid pattern across a target water body, the sorbent continuously extracts dissolved phosphorus from the surrounding water column — no chemicals, no mechanical filtration, no permanent infrastructure required.
“The performance advantage of our sorbent material over competing products is dramatic,” says Weber. “That translates directly into operational efficiency and cost per kilogram of phosphorus removed — which is what determines whether a remediation program is actually sustainable at scale.”
Once saturated, the sorbent is returned to a mobile regeneration trailer — a self-contained, PLC-automated processing unit — where it is washed, regenerated, and returned to service. The phosphorus extracted during regeneration is precipitated as tricalcium phosphate (Ca3(PO4)2), a high-purity compound suitable for use as a slow-release agricultural fertilizer. What begins as a pollutant is recovered as a commodity, creating a circular nutrient economy that offsets operating costs and generates independent revenue.
Commercial Traction and a Growing Market
LWNC is already operating with paid commercial trial partners in Manitoba, including the Town of Stonewall and the Rural Municipality of East Saint Paul — real-world validation ahead of broader deployment. The company is also advancing a multi-stream environmental credit strategy targeting water quality trading programs, environmental mitigation credits, and voluntary carbon markets.
With a growing patent portfolio, active municipal partnerships, and a platform backed by years of hands-on engineering and entrepreneurial experience, Weber and Lakewater Nutrient Capture are positioning Manitoba at the forefront of a global freshwater remediation market — one where a widespread environmental challenge becomes a sustainable economic opportunity.
“There are thousands of lakes across Canada facing this problem. The technology exists today to begin reversing that damage — and to build a viable industry around doing so.”
