Custom Plastic & Fiberglass Tanks
Custom Tanks
Built-to-Spec Storage for Water, Chemicals & Process Liquids
Custom tanks give you the footprint, capacity, and fittings your project actually needs—not a compromise. Our team designs plastic and fiberglass tanks for industrial, municipal, and commercial projects, with options for NSF-certified materials and Buy America compliance. Whether you’re storing potable water, corrosive chemicals, brine, or process fluids, we help you match the tank design to your code requirements, space constraints, and budget.

Custom Tanks for Industrial, Municipal & Commercial Projects
When you’re sizing a tank for a real project, “off-the-shelf” often means compromise. Our custom tank program is built for engineers, contractors, and facility managers who need specific volumes, footprints, and connection layouts. We design and supply tanks in both fiberglass reinforced plastic (FRP) and polyethylene to fit new builds, retrofits, and replacements.
Typical projects include water and wastewater treatment, industrial chemical storage, oil and gas, food and beverage, agriculture, brinemakers, scrubbers, and reactor systems. NSF-certified materials and Build America, Buy America compliant options are available when your spec requires them.
Custom Fiberglass Tanks (FRP)
Fiberglass reinforced plastic tanks are a strong fit when you need long-term corrosion resistance and light weight without sacrificing strength. Properly specified FRP tanks routinely deliver service lives measured in decades, while minimizing maintenance and repainting compared to coated steel.
Where Custom FRP Tanks Work Best
- Water and wastewater treatment plants
- Chemical storage (acids, caustics, salts, polymers)
- Oil & gas production and midstream facilities
- Food & beverage and process water systems
- Scrubbers, reactors, and brinemaker systems
- Outdoor installations where UV, weather, and corrosion are concerns
Key Advantages of Fiberglass Custom Tanks
- Corrosion-resistant: engineered laminates for aggressive fluids and harsh environments.
- Non-conductive: zero electrical conductivity for sensitive process areas.
- UV-stabilized: integral pigmentation and UV inhibitors help the shell stand up to sun exposure.
- Lightweight but strong: up to ~75% lighter than comparable steel tanks for easier handling and reduced foundation costs.
- NSF options: NSF-certified constructions available for potable water and food-contact applications.
- Buy America friendly: designs available to support Build America, Buy America requirements.
Custom Plastic Tanks (Polyethylene)
For many water and chemical projects, a rotationally molded polyethylene tank is the most efficient solution. We offer custom plastic tanks in a wide range of dimensions, wall thicknesses, and configurations, including vertical, horizontal, cone-bottom, rectangular, and low-profile designs.
Advantages of Custom Poly Tanks
- Seamless one-piece construction, reducing leak points.
- Excellent chemical resistance for many acids, alkalis, and salts.
- Potable water grades available with NSF or FDA-compliant resins.
- Black and colored resins for UV resistance and algae control.
- Cost-effective option for moderate pressures and ambient temperatures.

How We Build Custom Tanks to Your Specification
Custom doesn’t have to mean complicated. We use modern design tools and controlled manufacturing processes to deliver consistent, repeatable tanks that match your drawings and specs.
Engineering & Design
- Application review: product, temperature, specific gravity, and location.
- Material selection: FRP laminate schedule or resin grade for poly.
- Wall design based on loading, supports, and seismic/wind requirements.
- Nozzle, manway, and cleanout locations coordinated with your layout.
Manufacturing & Quality
- Automated and guided cutting/lay-up processes for consistent parts.
- Dimensional checks against approved drawings.
- Hydrotest or leak test options where required by spec.
- Documentation packages available for submittals and O&M manuals.
Fittings, Accessories & Options
Every project needs a slightly different combination of connections and access. We’ll help you specify the right fittings so the tank installs cleanly and works with the rest of your system.
- Nozzles: threaded, flanged, or stub-outs in your sizes and locations.
- Manways, hatches, and viewports for inspection and cleaning.
- Level indicators, gauge boards, and sensor ports.
- Ladders, platforms, and safety cages.
- Supports, saddles, skirts, and seismic restraint hardware.
- Insulation jackets and color options for outdoor or process use.
What We Need to Quote Your Custom Tank
A few minutes of upfront information saves days of back-and-forth later. Use this checklist when you send a drawing or RFQ:
- Stored product, concentration, and operating temperature range.
- Required working volume (gallons or liters) and preferred footprint.
- Indoor or outdoor installation, and whether it’s buried, at grade, or elevated.
- Applicable codes or standards (NSF, AWWA, local health codes, etc.).
- Loading conditions: specific gravity, agitation, mixing, or vacuum.
- Required fittings: size, type, and centerline elevations if known.
- Accessory needs: ladders, platforms, level instruments, insulation.
- Target lead time and any Buy America or documentation requirements.
Send us your sketches, legacy drawings, or a quick description, and we’ll help turn it into a buildable custom tank design.
