Plastic Tanks

Vertical plastic storage tanks give you big capacity without taking up much floor space. Each tank is molded from a single piece of UV-stable polyethylene that won’t rust, dent, or crack. Thick walls and a domed top handle the weight of stored water, lubricating oil, or even strong industrial chemicals. Capacities typically range from a few hundred gallons up to 10,000+ gallons, so you can match the size to your site and application.

Vertical Tank Types & Applications

• Vertical water storage tanks: Designed for potable or non-potable water storage, rainwater harvesting, irrigation supply, and fire protection reserves. Many models are built from FDA-compliant resins for safe drinking water storage.
• Vertical chemical storage tanks: High-density polyethylene (HDPE) and enhanced wall thickness make these chemical tanks suitable for acids, bleach, salts, and other corrosive liquids when used within compatibility guidelines.
• Vertical process and day tanks: Compact tanks used for batching, blending, and feeding treatment chemicals into water and wastewater systems, often with molded-in flats or pads for mixers and instruments.
• Industrial and municipal bulk storage tanks: Large vertical bulk tanks provide space-efficient storage for brine, process water, lubricants, and other industrial liquids in treatment plants and yards.

Vertical Plastic Tank Features & Benefits

• High-density polyethylene (HDPE) or linear polyethylene construction resists corrosion from water, salts, and many common chemicals.
• Seamless, one-piece design keeps the chemical storage tank leak-free under temperature swings and fluid head pressure.
• UV-stabilized resin protects tank contents in both indoor and outdoor installations for long service life.
• Available in water-only, premium, and heavy-duty wall thicknesses to match your specific gravity and duty-cycle requirements.
• Vented manways, molded-in gallon indicators, and translucent walls on many models for quick visual level checks.
• Flat-bottom design simplifies installation on a compacted, level pad or concrete slab.
• Accepts a wide range of chemical-grade fittings, valves, level sensors, and overfill protection devices for full system integration.

Chemical Tank – Harsh Liquid Storage

If you need a tank to store chemicals, choose our purpose-built plastic chemical tanks. Our vertical plastic chemical tanks use high-density resin that shrugs off acids, bleach, and salts. Every tank chemical rating is checked against our compatibility resources to help prevent stress cracking and leaks before they start. Each chemical storage tank is built with compliance and secondary containment in mind, and we carry a full range of vertical chemical tanks for treatment, dosing, and bulk storage.

Horizontal plastic tanks give you safe storage and transport capability for water, lubricating oils, fertilizers, and industrial chemicals. Their low-profile, flat design hugs trailers, truck beds, skids, and stands, so you can haul liquid where vertical tanks won’t fit. Rotationally molded in one seamless piece, these horizontal leg tanks are UV-stable and designed for storage and non-DOT-regulated transport applications where stability and low slosh are critical.

Horizontal Tank Types & Applications

• Horizontal leg tanks: General-purpose poly tanks from about 30 to over 5,000 gallons used for water, fertilizer, and light-duty chemical transport. Molded-in legs act as baffles to reduce sloshing and help stabilize the tank on trailers and skids.
• Applicator tanks: Smaller seamless tanks from 30 to 500 gallons, designed for mobile spray rigs and application equipment.
  • Lightweight and corrosion-resistant polyethylene construction.
  • Seal-tight lids and vented manways help prevent leaks in transit.
  • Optional saddles, bands, and brackets available for secure mounting.
• Space saver tanks: Compact, slimline tanks that fit easily in truck beds, service bodies, and tight equipment bays.
  • Typical sizes: 150, 200, and 250 gallons.
  • Molded fill indicator with 8" top opening for easy filling.
  • Ideal for dust control, washdown water, or small chemical loads.
• Elliptical tanks: High-capacity transport tanks with a low center of gravity for road and field use.
  • Leg models offer a very low profile for stability on trailers and trucks.
  • Capacities typically range from 335 to 5,025 gallons for large volume hauling.
  • Work well for nurse trailers, fire support, and agricultural spraying.

Horizontal Plastic Tank Features & Benefits

• Seamless, one-piece polyethylene construction with molded-in legs for strength and support.
• UV-stabilized resin for outdoor exposure and long-term durability in the field.
• Available with or without steel support bands, plus optional skids and cradles for permanent mounting.
• Optional metal bases, hose trays, and fittings available for turnkey sprayer and nurse tank packages.
• Translucent walls with molded gallon indicators on many models for quick level checks from the ground.
• End drain fittings and molded sump options help fully drain the tank for cleanout and chemical changeover.
• Offered in standard and heavy-duty wall thicknesses to match transport, specific gravity, and duty-cycle needs.

Chemical Tank Storage

For tougher duties, choose our horizontal plastic chemical storage tanks. High-density polyethylene resins and carefully engineered wall thicknesses help resist acids, bleach, and other aggressive solutions when used within compatibility guidelines. Chemical-grade vents, gaskets, and fittings provide leak-free service, and we stock tanks for chemical transfer and dosing in sizes from small day tanks to large transport-ready leg tanks. If you need a turnkey chemical tank, our horizontal designs deliver mobile capacity without sacrificing safety.

Specialty plastic tanks fill in the gaps where standard vertical or horizontal tanks won’t do the job. These engineered polyethylene tanks are designed for mixing, below-ground storage, spray applications, and tight-space installs. With options like cone bottoms, ribbed walls, underground cisterns, and custom fittings, they give municipalities, utilities, and contractors a flexible way to store and manage critical liquids.

Specialty Tank Types & Applications

• Mixing tanks (cone bottom tanks): For chemical, fertilizer, and water treatment mixing where complete drainage and suspension are important.
  • HDPE construction with excellent corrosion resistance against many common process chemicals.
  • Cone bottom ensures full drainage and minimal product heel for easier rinsing and changeover.
  • Open- and closed-top models available with lids, manways, or mixer mounts.
  • Typical sizes from 55 to 7,500 gallons for batch or continuous mixing.
  • Optional steel stands and support structures to elevate the cone for valve clearance.
• Septic tanks: Rotationally molded, leak-resistant plastic septic tanks for residential and light commercial waste handling.
  • Seamless design with internal ribbing for long service life and resistance to soil loads.
  • Lightweight for easier transport and installation with standard equipment.
  • Typical capacities from 300 to 1,500 gallons, with multi-compartment options in some models.
  • Watertight manways and risers available for inspection and pump-out access.
• Cistern tanks: Below-ground plastic cistern tanks for surplus or emergency water storage, irrigation, or stormwater capture.
  • Ribbed HDPE design resists soil pressure and prevents tank collapse when properly bedded.
  • Capacities from 325 to 2,500 gallons and larger, depending on the model.
  • Optional pre-plumbed inlet, overflow, and pump connections for easier installation.
