US Navy Selects Carver Water Technology for Critical Seawater Desalination System Deployment

Carver Water Technology recently secured a contract with the US Navy to design, build, and deploy emergency seawater desalination systems for Naval Station Everett's Emergency Management division in Washington State. This project demonstrates CWT's ability to engineer ruggedized watermaker systems that meet stringent military specifications while providing reliable potable water production in mission-critical scenarios.

The Naval Station Everett Project: Engineering for Reliability

The contract called for portable seawater reverse osmosis (SWRO) systems capable of producing 300 gallons per day of drinking water from Pacific Northwest seawater. These systems needed to meet specific criteria that position CWT as a leader in federal watermaker deployment:

Technical Specifications Delivered:

  • 300 GPD production capacity from seawater feedwater

  • Portable design under 200 lbs for rapid deployment

  • Operational pH range of 3.0-11.0 to handle varied water chemistry

  • 95%+ rejection rates for critical contaminants including heavy metals, radionuclides, bacteria, and chemical compounds

  • Complete spare parts package for field maintenance

  • UV sterilization integration for additional pathogen protection

What distinguishes this system is the comprehensive contamination rejection profile. CWT's system addresses the full spectrum of potential threats in emergency scenarios: heavy metal contamination (mercury, lead, cadmium 95-98% rejection), radiological material (95-98% rejection), chemical threats (cyanide 90-95%, chromate 90-97%), and biological hazards (bacteria 99%+, cysts 98-99%).

Why Federal Agencies Choose CWT Watermaker Technology

Federal procurement requires systems that function reliably during disasters, contamination events, or infrastructure failures. CWT's approach addresses these requirements through several key differentiators:

Mission-Critical Design Philosophy

The Naval Station Everett deployment exemplifies CWT's engineering approach. Emergency Management requires systems that can operate immediately after natural disasters, contamination incidents, or infrastructure failures. No warm-up period. No ideal feedwater conditions. No shore power guarantee. The system either produces safe drinking water or people don't have water.

CWT systems are engineered specifically for these conditions. While commercial marine watermakers like the Parker Village Marine Pure Water Series serve their intended markets effectively, federal applications demand different capabilities. CWT focuses exclusively on emergency response, military readiness, and critical infrastructure scenarios where reliability under adverse conditions determines mission success.

Complete Contamination Spectrum Protection

Federal applications require documented rejection rates across dozens of specific contaminants because agencies must certify water safety under EPA standards. CWT provides this certification through multi-stage treatment:

The pre-filtration stage (carbon/phosphate filter plus 2.5" sediment filter with 1.5" 140-mesh polyester element) removes particulates and protects the Dow FILMTEC SW30-2.5x21 membrane element. This commercial membrane achieves the specified rejection rates across the full contamination profile. The UV sterilization stage (Ampac USA 1gpm system) provides final pathogen inactivation, ensuring EPA microbial standards compliance even if membrane integrity degrades slightly.

This approach ensures water quality cannot be assumed and testing may not be immediately available during emergency operations.

Rapid Deployment Capabilities

The sub-200 lb weight specification reflects operational reality. Two personnel can deploy a CWT system without mechanical assistance. During Hurricane Maria response operations throughout the Caribbean, CWT learned that deployment speed often determines whether communities have water within hours or days.

The compact 25"L x 18"W x 19"H footprint allows transportation in standard vehicles and aircraft. No specialized lifting equipment. No dedicated cargo space. The system fits in a pickup truck bed or helicopter cargo bay and two people can have it operational within an hour of arrival.

This portability directly supports federal emergency response protocols where equipment must reach remote locations quickly and begin producing water immediately upon arrival.

Comprehensive Spare Parts Integration

Federal emergency response cannot depend on supply chains or dealer networks during crisis situations. CWT's Naval Station Everett system includes complete redundancy: duplicate filters, additional membrane elements, extra UV lamp assemblies, and replacement components for high-wear items.

If the primary membrane fouls, operators swap in the spare and restore production within minutes. If the UV lamp fails, the replacement is already in the kit. This redundancy costs approximately 40% of base system price, but it ensures sustained operations when supply chains are disrupted.

Federal Procurement Advantages: Why CWT Wins Government Contracts

The Naval Station Everett award highlights several strategic advantages CWT brings to federal procurement:

MBE/VOSB Certifications

As a company pending Minority Business Enterprise and Veteran-Owned Small Business certifications, CWT provides federal agencies with set-aside contract opportunities while delivering enterprise-level technical capabilities. This combination allows procurement offices to meet socioeconomic goals while acquiring mission-critical water systems from a technically qualified contractor.

Same-Day Emergency Response Throughout Service Territory

CWT maintains field service capabilities across Central Florida, the Southeastern United States, and Caribbean markets. When Naval Station Everett needed troubleshooting during acceptance testing, CWT had engineers on-site within 48 hours. This field service capability ensures federal installations receive immediate technical support during emergencies or operational challenges.

Custom Engineering for Specific Requirements

The 300 GPD specification emerged from Naval Station Everett's specific operational requirements: emergency shelter capacity, duration of potential infrastructure outages, and available storage capacity. CWT engineered the system specifically to these parameters rather than adapting existing products to partially meet needs.

Federal agencies benefit from this flexibility because their requirements emerge from operational analysis. A FEMA deployment might need 1,000 GPD capacity in a towable configuration. A Coast Guard station might need 100 GPD with solar power integration. CWT engineers these variations to exact specifications.

Caribbean Market Expertise and Infrastructure

CWT's continuous work throughout the Caribbean provides direct experience with the water challenges federal agencies face in island territories and overseas installations. The Rahming Family Store deployment in South Andros, Bahamas, solved potable water access for an underserved island community. The Runaway Bay wastewater treatment commissioning in Jamaica demonstrated advanced treatment technology implementation in resource-constrained environments.

When SOUTHCOM, the Coast Guard, or Department of Interior procurement offices evaluate watermaker contractors for Caribbean or Pacific island installations, CWT's demonstrated regional experience, established logistics capabilities, and regional supplier relationships provide significant operational advantages.
