Assessment to restoration

A restoration pathway built around evidence

Cascade doesn’t begin by prescribing equipment. We begin by determining how phosphorus moves through the lake, where it becomes concentrated, and whether a feasible engineered export pathway exists.

01 · Cascade Assessment

Know whether removal matters before investing in treatment

The Cascade Assessment determines whether permanent phosphorus removal can materially change a lake and whether treatability work or a field pilot is justified.

No fixed price is published in V1; scope depends on the lake and available evidence.

02 · Cascade Treatability Study

Test real water before choosing a process

Organic matter, suspended solids, iron, alkalinity, competing ions, and flow conditions can dramatically alter the performance of phosphorus-capture technologies.

Concentrated inflows

Capture phosphorus before it reaches the lake

Cascade Aquatics is developing modular nutrient-removal systems that target phosphorus where nature has already concentrated it—inside impaired lakes and in nutrient-rich inflows.

A nutrient-rich tributary flows into a shore-based capture unit before reaching a lake. Cleaner water continues to the lake while captured phosphorus leaves the system in a separate vessel. — Intercept a concentrated tributary or high-load event before phosphorus reaches the lake.

03 · Cascade Pilot

Prove removal in the field

The pilot moves the best-supported treatment approach into the field. The goal is not merely a lower effluent concentration—it is a defensible phosphorus mass balance and credible operating economics.

04 · Cascade Restoration

Restoration as a service

For appropriate lakes, Cascade’s long-term model is Restoration-as-a-Service: owning or operating modular systems and managing the extraction, capture, monitoring, and reporting required for a measurable nutrient-removal program.

Customers should not have to become treatment-plant operators to restore their lake.
