Commercial Water & Wastewater Systems Yakima WA
At Fextex Systems, we specialize in sustainable water and wastewater management solutions. Founded in 1997, we pioneered fiberglass tank systems for commercial applications after partnering with Xerxes, a leader in petrochemical-grade fiberglass manufacturing. Our innovative products include underground and above-ground fiberglass tanks, AdvanTex Treatment Systems, and UV disinfection units designed for durability and efficiency. We offer comprehensive project support, including design assistance, technical documentation, and expedited delivery to meet construction deadlines.

Our team works directly with engineers, contractors, and government entities to address project-specific challenges while emphasizing cost-effective, long-term infrastructure solutions. With expertise in nitrogen reduction, pump station integration, and system customization, we empower clients to overcome design obstacles while maintaining environmental responsibility. Our commitment to quality is evident in our 100% watertight construction standards, corrosion-resistant materials, and focus on one-day installation capabilities that minimize project delays.

Services
Fiberglass Tanks
Our fiberglass tanks provide durable water and wastewater storage solutions. Constructed to petroleum tank standards, they resist corrosion and maintain structural integrity underground. Available in customizable sizes for potable water, fire protection, stormwater detention, and wastewater applications while enabling rapid installation due to lightweight design.
AdvanTex Treatment Systems
Modular packed bed media systems treat wastewater through multi-pass filtration. These compact units reduce BOD, TSS, and ammonia nitrogen levels while maintaining consistent performance. Configurable as single or dual-stage systems, they offer tertiary polishing capabilities for commercial applications requiring advanced treatment standards.
Pump Stations
Engineered pump packages handle water transfer requirements for municipal and commercial clients. We provide complete solutions including basin design, pump selection, and control panel configuration. Systems accommodate various flow rates while managing solids handling and corrosion resistance for wastewater applications.
UV Disinfection Units
UL-listed ultraviolet treatment systems eliminate microorganisms in water streams. Crossfire technology enhances disinfection efficiency while reducing maintenance demands. These units integrate with existing infrastructure to meet regulatory compliance for effluent discharge or reuse applications.
Nitrogen Reduction Filters
Passive upflow filtration systems reduce nitrogen content in wastewater streams. Designed for simplicity and minimal maintenance, these units achieve nutrient removal through biological processes. Ideal for sensitive environmental areas requiring stringent nitrogen discharge limitations.
Questions
What types of fiberglass tanks do you manufacture?
We produce underground and above-ground fiberglass tanks for wastewater, potable water, fire protection, stormwater detention, and rainwater collection applications. All tanks meet petroleum industry watertight standards.
Do you provide engineering support for commercial projects?
Yes. Our team offers technical assistance including hydraulic calculations, CAD drawings, and installation manuals. We support engineers and contractors throughout the project lifecycle.
How do AdvanTex Treatment Systems work?
AdvanTex systems use multi-pass textile media filters to reduce BOD, TSS, and ammonia nitrogen. Wastewater recirculates through the system with optional dual-stage configurations for enhanced treatment performance.
What pump station configurations are available?
We supply submersible, end suction, and vertical turbine pump systems. Custom configurations include control panel integration and basin design for specific flow requirements.
Can you help meet tight construction deadlines?
Yes. We prioritize expedited deliveries when required and provide technical sales representatives to streamline the quoting and submittal process for time-sensitive projects.
