Crystal Stream Technologies

What Crystal Stream Technologies does

Crystal Stream Technologies, operating under parent entity Practical Best Management of Georgia, Inc., is a privately held U.S. manufacturer of structural stormwater treatment Best Management Practices (BMPs). Founded in late 1999 with first field deployments in 2000, the company designs and patents concrete-and-aluminum vault systems that screen, separate, and filter sediment, trash, nutrients, hydrocarbons, and other pollutants from stormwater runoff before discharge to receiving waters. Its two flagship products are the CrystalClean separator, an original fiber-filter device with 25+ years of field performance, and the CrystalClear-Choice, a newer patented device that adds customizable up-flow media boxes with a periscope bypass structure and ground-level maintenance access. Third-party field validation has been conducted under the EPA's ETV program, by the USGS, and under a Clean Water Management Test Fund grant, supporting regulatory credibility across U.S. jurisdictions.

The company's business model is a hardware sale conducted exclusively through a vetted network of local precast partners across 50+ U.S. states, with CST retaining engineering approval on every quote. Devices range from approximately $11,000 for the smallest 6 cfs unit to approximately $50,000 for the largest 36 cfs unit, with site-specific design, drawings, and revisions provided at no charge to the specifying engineer. Customer segments span engineering firms (primary specifiers), contractors (installers), commercial/industrial/municipal site owners (purchasers), and regulators (approving authorities). An affiliated entity, Storm System Services, provides post-installation cleaning, maintenance, and emergency spill response, creating a recurring service revenue stream on the installed base of thousands of devices.

CST is led by founder and CEO John Moll, who holds nine U.S. patents on the vault systems, and Earl Duckett as principal engineer. The company has placed thousands of devices in the field and accumulated 9,000+ specified plans over its 25-year operating history. There is no disclosed external venture or growth equity investment, and the business appears to be founder-owned and self-sustaining through operations.

Revenue model

1. BMP Device Sales: CST generates revenue primarily from the sale of custom-manufactured stormwater treatment BMP devices. Devices range from approximately $11,000 for the smallest 6 cfs capacity unit to approximately $50,000 for the largest 36 cfs unit. Devices are quoted by vetted local precasters with CST's approval. The vault cost is separate from riser costs (typically under $5,000) and installation costs (variable by region). This is a one-time hardware sale model with ongoing maintenance service opportunities through affiliated Storm System Services.
2. Engineering Design Services: CST provides engineering design, detailed site-specific drawings, fabrication documents, and design reports at no charge to the customer. Initial design and revisions are provided at no charge. The company does not charge for the design — revenue is generated when the customer orders the device through the precast partner network.
3. Operations & Maintenance Services (via Storm System Services): CST maintains an ongoing relationship with site owners post-installation. An affiliate, Storm System Services (678-990-0178), provides cleaning, maintenance, and emergency services such as spill response. This represents a recurring service revenue opportunity tied to the installed device base.

Core offering

Crystal Stream Technologies manufactures and supplies site-specific engineered stormwater treatment Best Management Practice (BMP) vaults, with two flagship products: the CrystalClean Separator (built-in fiber filter, trash basket, baffles, and spill protection) and the CrystalClear-Choice device (customizable up-flow media boxes for targeted pollutant filtration). Devices are custom-engineered for each site, quoted through a vetted precast partner network, and supported by an affiliate (Storm System Services) for ongoing maintenance.

Product overview

Crystal Stream Technologies offers a portfolio of two primary stormwater treatment BMP (Best Management Practices) devices: the CrystalClean Separator with integrated fiber filter for standard applications, and the CrystalClear-Choice with customizable filtration media for specialized pollutant removal. Both products are site-specific engineered designs made from concrete and aluminum, featuring underground vault installation with top-down maintenance access. The CrystalClean serves most commercial sites while CrystalClear-Choice addresses industrial and 'hot spot' applications requiring specific media treatment.

Brands

• CrystalClean: Original stormwater separator product with fiber filter for water quality treatment. Equipped with trash basket, fiber filter, baffles for flow distribution, and built-in spill protection.
• CrystalClear-Choice

Products and services

• CrystalClean Separator Original stormwater treatment BMP device with built-in fiber filter, trash basket targeting nutrients, fiber filter catcher for organics and metals, baffles distributing flow to maximize separation, and built-in spill protection. Treats water quality flows from 0.4 to 9.95 cfs and typically remains online for maximum flows of 2 to 36 cfs across the model range. Used by engineers, contractors, site owners, and regulators on commercial and municipal sites where standard suspended solids and trash removal is required.
• CrystalClear-Choice Multi-purpose stormwater treatment device with a front-end separator and customizable up-flow media boxes that allow targeted filtration, adsorption, or absorption for specific pollutants. Uses a periscope bypass structure to direct a measured portion of flow under and up through selected media boxes while higher flows bypass, keeping the device online during large storm events. All media boxes can be inspected, cleaned, and replaced from ground level without confined space entry. Designed for industrial, 'hot spot', and other applications requiring specific media treatment.
