Graver Water Systems

What Graver Water Systems does

Graver Water Systems, operating legally as Marmon Industrial Water LLC, is a US-based manufacturer of industrial water and wastewater treatment equipment serving the power generation, petrochemical, food and beverage, and sugar processing sectors. Founded in 1905 and now a subsidiary of Marmon Group (a Berkshire Hathaway-owned diversified industrial conglomerate), the company is headquartered in Warren, New Jersey with additional offices in Houston, Texas and Burlington, Ontario. The company operates under two trade names, Graver Water and Marmon Industrial Water, following a corporate rebranding.

Graver's product portfolio spans the full industrial water treatment value chain: raw water pretreatment (Reactivator clarifiers, Lamella inclined plate clarifiers, Rota-Rake thickeners, Monoscour/Filter-Pak/Scour-Pak gravity filters, pressure filters, lime softeners), boiler and cooling tower makeup water (GravFlex multi-media, carbon, and softener filters, ROFlex reverse osmosis, ElectroFlex electrodeionization, UltraFlex ultrafiltration, Oceana seawater RO), condensate treatment (Powdex precoat filter demineralizers, deep bed polishers with SepraEight regeneration, GRF polishers, AFA backwashable filters, TurboGuard filters, mPowdex mobile polishing trailers, deaerators via sister company Ecodyne), wastewater treatment, oil/water separation (Trisep coalescers, HydroFlow walnut shell filters, FlowGuard ABC filters, IGF induced gas flotation), and process treatment (Prima-Sep sugar clarifiers, Scepter cross-flow stainless steel UF/MF systems). Core technical differentiators include proprietary Powdex precoat ion exchange technology with over 40 patents, capabilities up to 33,000 gpm per single installation, and specializations in nuclear-grade and extreme-condition operation (pH 0-14, up to 600°F, up to 1,000 psig).

The business operates an enterprise B2B direct sales model with custom-engineered, quote-based equipment sales as the primary revenue stream, supplemented by aftermarket parts and service (supported by 60-year equipment archives) and a growing mobile condensate polishing rental offering. Graver holds dominant market positions in North American condensate polishing (>75% Powdex share, >60% deep bed share over the last 15 years), serves nearly 60% of US nuclear plants and 100+ worldwide nuclear installations, and holds over 70% of the global replacement powdered resin market. Go-to-market relies on direct enterprise sales, long-standing relationships with major EPCs (Bechtel, Black & Veatch, Shaw Stone & Webster, Fluor, Sargent & Lundy), and dedicated sales/parts/service channels under the marmonwater.com domain.

Direct peers

• Evoqua Water Technologies: Evoqua (now part of Xylem) is the closest direct competitor to Graver, supplying industrial water treatment systems, condensate polishing, filtration, and aftermarket service into power, nuclear, and petrochemical customers. Overlap is particularly strong in North American condensate polishing and utility-grade demineralization.
• Aquatech International: Aquatech is a smaller, focused industrial water treatment specialist serving power generation, oil & gas, and mining with similar capabilities in raw water pretreatment, boiler feedwater, condensate polishing, and zero liquid discharge. Direct overlap with Graver in industrial reuse and high-purity applications.
• Ovivo Inc. Ovivo supplies water and wastewater treatment solutions for power, municipal, and industrial customers with comparable products in filtration, clarification, and ion exchange. Similar size and niche focus make Ovivo a closely comparable peer to Graver in industrial water treatment.
• Pall Corporation: Pall (a Danaher operating company) is a global filtration specialist whose industrial filters, membrane systems, and condensate filtration products directly overlap with Graver's AFA, TurboGuard, and Scepter lines. Particularly relevant in power, petrochemical, and oil & gas applications.

Broad incumbents

• Veolia Water Technologies: Veolia Water Technologies is the largest global industrial water treatment platform with overlapping capabilities in filtration, RO, ion exchange, and process water for power and petrochemical customers. Operates at much larger scale and across many geographies, but competes with Graver for the same utility and EPC specifications.
• SUEZ Water Technologies & Solutions: SUEZ (now combined with Veolia in many markets) historically competed head-to-head with Graver in industrial water treatment and condensate polishing for power and refining customers. Comparable broad portfolio (filters, RO, ion exchange, chemicals) but at much larger scale and with greater chemical and services weight.
• Xylem Inc. Xylem is a large diversified water technology company that owns Evoqua, Wedeco, and other brands directly overlapping with Graver's filtration, RO, and demineralization portfolio. Competes primarily as a broad incumbent across utility, industrial, and commercial water markets.
• Pentair plc: Pentair is a broad water treatment and flow technology company with industrial filtration, RO, and water reuse products that overlap with Graver's portfolio. Larger and more diversified across residential, commercial, and industrial segments.
• Ecolab Inc. Ecolab is a large industrial water, hygiene, and process treatment company with significant overlap in cooling tower, boiler, and process water treatment for power, refining, and F&B customers. Competes via chemistry-heavy programs and digital water management rather than purely engineered equipment.

Emerging players

• Fluence Corporation: Fluence (formed from the merger of RWL Water and Emefcy) focuses on decentralized and packaged water and wastewater treatment for industrial and municipal customers. Smaller and more emerging, but directly comparable to Graver's modular, packaged treatment approach.
