Clearstream

What Clearstream does

ClearStream Environmental is a privately held US manufacturer of custom-engineered process equipment for the water and wastewater treatment industry, founded in 2002 and headquartered in Sandy, Utah. The company designs, fabricates, and supplies a full portfolio of physical separation and biological treatment systems — including multiple clarifier architectures (spiral blade Nautilus, segmented, suction header, suction pipe, solids contact, rectangular, inclined plate), conventional and paste thickeners, the ClearFlo family of biological reactors (SBR, jet aeration, continuous loop reactor, trickling filters, bullseye oxidation channel), dissolved air flotation units, disc and walnut shell filters, oil-water separators, and proprietary heavy-duty drive units with 100-year bearing life design and 10-year warranty. Technical differentiators include the Nautilus logarithmic spiral blade clarifier, the ClearFlo jet aeration system with no moving parts in the liquid, paste thickeners capable of reducing wash water in CCD circuits by up to 40%, and a 3D modeling workflow applied to every project.

The company serves municipal water and wastewater utilities, power generation, oil and gas, mining, and broader industrial customers (pulp and paper, chemical, food and beverage, steel) through a direct, consultative engineering sales motion. Revenue is generated through one-time equipment sales, turnkey EPC project delivery, field services (startup, training, maintenance, troubleshooting), equipment retrofits and drive replacements, and aftermarket spare parts. Pricing is quote-based with no public tiers. Notable customers include Macon Water Authority, Fields Point WWTP, Sandy Creek and Belews Creek power stations, BP Chemical, Ambatovy (Madagascar), Cortez Gold Mine, and Consol Energy. The aftermarket, retrofit, and service lines are positioned as recurring-revenue channels around the installed base.
