Engineered for Resilience: Submersible Enclosures for Water & Wastewater Treatment

Protecting electrical controls in water infrastructure requires more than a standard waterproof enclosure. Treatment plants, lift stations, and coastal facilities place control systems in environments exposed to flooding, chemical treatment processes, and long-term moisture.

When engineers develop specifications for these systems, enclosure performance becomes a critical design variable. The enclosure must protect sensitive electronics while integrating cleanly into the project’s electrical and mechanical plans.

SLAYSON® manufactures submersible enclosures for water treatment designed for prolonged immersion in aggressive municipal environments. Our enclosures meet NEMA 6P and IP68 standards and protect control systems installed in flooded vaults, wet wells, and chemical processing areas.

Because engineers must integrate enclosure data directly into design packages, we provide CAD models and engineering drawings that support specification development and project documentation.

Why Engineers Specify SLAYSON® for Water Treatment Infrastructure

Water treatment environments expose electrical equipment to conditions that quickly degrade standard enclosures. Flood exposure, corrosive gases, and chemical treatment processes must all be addressed during the design phase.

SLAYSON® develops enclosure systems with these infrastructure conditions in mind, while also supporting the workflow that engineers follow when preparing specifications and bid documents.

Corrosion Resistance in Wastewater Environments

Many wastewater treatment facilities generate hydrogen sulfide (H₂S), a gas that accelerates corrosion on exposed metal components. Chlorine and other treatment chemicals can introduce additional chemical exposure around instrumentation and control systems.

SLAYSON® commonly manufactures enclosures from 316 stainless steel, a material selected for improved corrosion resistance in chemical processing environments.

We also incorporate single piece Neoprene gasket systems that maintain sealing performance during long-term exposure to moisture and treatment chemicals.

This construction helps protect instrumentation, sensors, and wastewater treatment equipment housing used throughout municipal treatment infrastructure.

Flood-Proof Protection for Aging Infrastructure

Municipal infrastructure places electrical systems inside underground vaults, lift stations, and service chambers near waterways or drainage systems.

When engineers prepare design specifications for these installations, they must account for the possibility of full enclosure submersion.

SLAYSON® NEMA 6P wastewater enclosures are designed for prolonged immersion rather than temporary splash protection. While NEMA 4X enclosures address corrosion and washdown conditions, NEMA 6P enclosures are tested for extended submersion.

For engineers specifying equipment inside flooded vaults or lift stations, that distinction directly affects system reliability during extreme conditions.

Custom Engineering Support

Water treatment projects require modifications that standard catalog products cannot provide.

SLAYSON® works directly with design engineers to develop enclosure configurations that match specific system requirements. These modifications can include:

• Welded conduit hubs for direct electrical connections
• Optical windows that allow visual inspection of internal indicators without opening the enclosure
• Custom mounting systems for instrumentation and control components
• Layout adjustments to meet space constraints within vaults or treatment equipment

Engineering teams also provide CAD models and detailed drawings that integrate into project design documentation.

For engineers preparing system specifications or bid documents, fast access to accurate models reduces delays during the design phase.

Water Treatment Applications

SLAYSON® enclosures are commonly used across municipal and industrial water infrastructure where electronics must remain operational in submerged or chemically aggressive environments.

Wastewater Lift Stations

Lift stations house pump controls and monitoring equipment inside below-grade vaults where flooding is possible. SLAYSON® submersible enclosures protect these electrical systems from water intrusion while allowing long-term installation in confined infrastructure spaces.

Desalination Plants

Desalination facilities expose electrical systems to high salinity conditions. We frequently specify 316 stainless steel enclosures for these environments because the material provides improved corrosion resistance in marine and coastal installations.

Chemical Dosing Systems

Water treatment processes involve chlorine, acids, and other aggressive chemicals. SLAYSON® enclosures installed near dosing systems isolate sensitive electronics from airborne chemical exposure while maintaining a sealed enclosure environment.

Municipal Infrastructure

Public water utilities rely on equipment designed for long service life and predictable performance. SLAYSON® submersible enclosure systems help protect instrumentation used in municipal infrastructure while reducing maintenance issues caused by water ingress.

Product Solutions for Water Treatment Engineers

SLAYSON® manufactures several enclosure series used throughout water and wastewater treatment projects.

ASM Series: Standard Submersible Enclosures

The ASM series provides submersible protection for applications requiring immersion up to 15 feet. Engineers often use these enclosures for control panels and monitoring systems located in flooded infrastructure areas.

ASMI Series: Industrial Submersible Enclosures

The ASMI series expands customization options for complex systems. Design engineers frequently specify this series when projects require:

• Optical viewing windows
• Custom-welded hubs
• Specialized internal layouts for instrumentation and control equipment

These features allow system monitoring while maintaining enclosure integrity.

Subsea Series: Deep Immersion Applications

Some infrastructure and industrial applications require protection under deeper water or higher pressure conditions. The Subsea series supports installations where standard submersible enclosures may not provide adequate pressure resistance.

Engineering Support for OEM, Utility, and Contractor Projects

SLAYSON® customers typically fall into two groups.

OEM manufacturers integrate our enclosures into specialized equipment systems. These projects often involve testing and evaluation before production orders begin.

Utility companies and contractors require enclosures that can be specified in infrastructure design documents or used to solve water ingress problems in existing facilities.

In both situations, engineering responsiveness is critical.

Engineers need enclosure specifications quickly to finalize design packages or submit bid proposals. SLAYSON supports these timelines by providing:

• CAD models
• Engineering drawings
• Specification assistance
• Rapid response to design inquiries

This allows project teams to complete documentation and move projects toward procurement.

Submersible Enclosures Designed for Water Treatment Infrastructure

Water treatment infrastructure depends on electrical systems that must operate in environments exposed to flooding, chemical treatment processes, and continuous moisture.

SLAYSON® manufactures submersible enclosures for water treatment engineered for prolonged immersion, chemical exposure, and long-term infrastructure use. Our NEMA 6P and IP68 enclosure systems support engineers designing municipal water and wastewater facilities.
