Plastic Tanks

Vertical plastic tanks from One Clarion offer above ground liquid storage for water or chemicals. They can handle temperature and weather changes, so our plastic tanks can be used both indoors and outdoors. Every vertical tank is rotationally molded, so they are seamless and watertight. Vertical water tanks are constructed of 100% virgin resin, as required by the FDA for potable water storage.

Vertical polyethylene tanks can be used as bulk storage tanks. Large plastic water tanks come in a wide range of capacities and models for storage of water and other liquids.

• Dome Top - 10 to 20,000 Gallons
• Flat Top - 20 to 5,000 Gallons
• Water Only - 1,100 to 10,000 Gallons

We also provide many common polypropylene fittings, from bulkhead and bolted fittings to ball valves for our vertical water storage tanks. Please Contact Us for a complete listing.

Horizontal tanks are used primarily for water transport and as chemical nurse tanks. Horizontal tank models include the leg tank, applicator tank, the space saver, and the elliptical tank.

Horizontal Leg Tank

Molded legs provide extra tank support, making the horizontal leg tank very stable with a low center of gravity.. They also act as baffles during transport to reduce water movement. Horizontal water tank size options range from 35 to 5,025 gallons. Horizontal leg tanks are available with or without support bands. Beyond the typical fitting accessories, metal tank bases can provide additional support.

Applicator Tank

The smaller applicator tank comes in capacities from 20 to 500 gallons. Like all our plastic tanks, they are seamless, lightweight, and corrosion resistant. The unique lid sealant system eliminates loss of liquid during travel. Tank saddles are also available to fit the applicator tank plus your own equipment.

Space Saver

When space is limited, the slimline space saver poly tank fits in most trailers and truck beds. The cut away style easily shows the water level against the molded indicator. The tank comes in three capacities: 150, 200, and 250 gallons. Each has an 8 inch easy-to-reach fill opening.

Elliptical Tank

Polyethylene elliptical tanks are designed specifically to transport large quantities of water or chemicals. In particular, the elliptical leg tank model has the lowest center of gravity among plastic tanks. It also features molded legs similar to those of the horizontal tank that act as baffles, reducing liquid movement and providing support during transport. Elliptical tank capacities range from 335 to 4,035 gallons.

Our specialty plastic tanks are designed for a range of specific applications. Whether your city needs septic, pest control, or water storage, chemical containers for mixing, or fertilizer spot spraying, we have plastic poly tank solutions.

Mixing Tanks

Cone bottom tanks offer easy mixing for chemicals and other liquids. High-density polyethylene allows for both indoor and outdoor use. Quick and complete drainage is simple with the conical bottoms. Closed and open top designs are available, as well as corrosion-resistant steel stands. Depending on the cone bottom tank model, sizing ranges from 55 to 7,500 gallons.

Septic Tanks

Plastic septic tanks are constructed of seamless, rotationally molded plastic to prevent leaking from joints and other weak spots. The ribbed design allows for better placement and hold in the ground. Ranging from 300 to 1,500 gallons, plastic septic tanks are easily transported to an installation site in a regular pickup truck.

Cistern Tanks

Cistern tanks offer additional storage for Water Management to ensure their community has access to adequate water supplies. Similar to the plastic septic tank model, below ground plastic cistern tanks use a ribbed design. With capacities from 325 to 2,500 gallons, our plastic tanks can help supplement wells and any emergency water caches.

Pest Control Tanks

Pest control operator (PCO) tanks use rotationally molded polyethylene and a ribbed design to create a strong, sturdy tank for pesticides and fertilizers. Standard features include an 8 inch fill well, splash guard cover, agitation areas, and optional bulkhead brackets. PCO Tanks come in sizes to hold between 30 and 300 gallons of liquid.

Spot Sprayer Tanks

Our spot sprayer tanks are the right size to fit in the back of a golf cart or small truck for quick spot watering or fertilizing of plants and other greenery around the city. Capacities range from 15 to 60 gallons with dimensions from 14 x 32 x 14 feet to 24 x 36 x 26 feet.

We have a wide variety of plastic tanks that you can customize to your specifications. You can choose from different colors, shapes, and sizes to make your tank unique and perfect for you! see Speciality & Custom Tanks.
