What Cleanwater1 does

Cleanwater1 is a privately held U.S. water quality and wastewater treatment equipment company headquartered in Milpitas, California, operating a roll-up of seven subsidiary brands (UGSI Chemical Feed, PAX Water Technologies, PSI Water Technologies, VeloDyne, Industrial Control Systems Online, Integrity Municipal Systems, and PureAir Filtration). The company engineers, manufactures, and services chemical feed systems, on-site hypochlorite generation units (Microclor®), water storage tank mixers (PAX Water Mixer), polymer activation systems (Polyblend®, Dynablend™, VeloBlend, HydraMax™), chemical metering pumps (Encore®), flow meters (Varea-Meter®), automated residual control systems (Monoclor® RCS), and a full line of gas-phase air purification equipment including dry scrubbers, biological scrubbers (BEAST™), emergency chlorine scrubbers, and proprietary chemisorbant media. Products serve municipal water and wastewater utilities, correctional facilities, data centers, oil/gas/chemical, pulp and paper, food and beverage, mining, resorts, and pharmaceutical clients globally.

The company's business model is enterprise field sales of engineered systems with quote-based pricing, complemented by recurring revenue from parts and consumables, service agreements, fabrication and assembly services, containerized and trailer-mounted systems, and equipment rentals. Distribution is primarily direct through a field sales organization with a global footprint spanning North America, the Middle East, and Europe, supplemented by an e-commerce parts ordering channel. The company is currently deploying a computer vision-based product (SludgeVision) for sludge dewatering optimization, indicating the early introduction of AI-adjacent capabilities into an otherwise primarily mechanical and chemical-engineering-driven product portfolio. Revenue is not publicly disclosed; the firm has executed multiple acquisitions (VeloDyne in January 2024, ICS Online in June 2025) and a series of capital raises (2016, 2018, 2020) consistent with an active growth strategy.

Cleanwater1's growth is supported by a comprehensive go-to-market motion that includes an extensive educational webinar series, a 133+ document resource library, the Cleanwater1 Academy online training platform offering CEU/PDH credits, a sizing tools portal, NAWC Platinum Sponsorship, and an active trade show and events program. The company emphasizes its position as the only provider offering complete end-to-end water quality, wastewater, and odor control solutions under one roof, leveraging legacy brand recognition (Wallace & Tiernan heritage in Encore® pumps and Varea-Meter® flowmeters) and proprietary technology portfolios protected by registered trademarks and patents.

Core offering

Cleanwater1 designs, manufactures, and services engineered systems for municipal and industrial water and wastewater treatment, including on-site hypochlorite generation, polymer activation, chemical metering, tank mixing, residual management, and gas-phase odor and toxic gas control. The company operates through multiple subsidiary brands (UGSI Chemical Feed, PAX Water Technologies, PSI Water Technologies, VeloDyne, IMS, ICS, and PureAir Filtration) providing end-to-end air, water, and wastewater solutions. Products are sold via direct field sales, supported by service agreements, parts/consumables, fabrication, and assembly services.

Product overview

Cleanwater1 offers a comprehensive portfolio of water quality, wastewater treatment, and odor control products organized as a platform-plus-acquired-brands architecture. The core product lines center on chemical feed and disinfection (Microclor® OSHG for on-site hypochlorite generation, Encore® metering pumps), polymer activation systems (Polyblend®, Dynablend™, VeloBlend, HydraMax™), mixing solutions (PAX Water Technologies mixers for tank stratification control), residual management (Monoclor® RCS), and air quality systems (PureAir® dry scrubbers and chemisorbant media). The company has grown through strategic acquisitions, bringing together seven subsidiary brands—UGSI Chemical Feed, PAX Water Technologies, PSI Water Technologies, VeloDyne, Integrity Municipal Systems, Industrial Control Systems Online (ICS), and PureAir® Filtration—each contributing specialized product lines while maintaining distinct brand identities. The portfolio integrates water treatment, chemical dosing, odor control, toxic gas protection, and industrial automation under one unified company.
