Plastic Water Tank Details

Made from virgin polyethylene resin, the plastic water tank has molded grooves for steel hoops that secure and support the tank. Horizontal plastic tanks also have convenient gallonage markings at the end of the tank to allow for an accurate and economical use of water and chemicals. Molded legs support the tank for easy application in various scenarios. The plastic water tank is even equipped with molded partial baffles to prevent weight shifting of contents during transport.

All horizontal plastic tanks come with a flat bottom style to allow for easy mounting on trucks, trailers, or tank stands . The 1000 gallon poly tank is also available in a "full-drain" model that slopes from the sides and the ends to allow for complete draining of the tank. It can also replace the water tank on the 1000 gallon water trailer if a new tank is needed. The 1200 gallon plastic tank and 1600 gallon plastic water tank models are elliptical leg tanks with low centers of gravity and side fill wells, making them easier and safer to service. The 1600 gallon plastic water tank can be used as a replacement if needed for the 1600 gallon water trailer.

Skids are available for plastic water tanks to allow them to be easier to load and unload on trucks and trailers. Horizontal plastic tanks come in two color options, translucent white or black, which are algae-resistant.


Horizontal Plastic Tanks Applications

Horizontal plastic tanks, sometimes called nurse tanks, are a versatile solution for storing and transporting a wide range of liquids. These plastic water tanks are commonly used in:

  • Agriculture: Nurse tanks for water, liquid fertilizer, herbicides, and crop protection chemicals.
  • Dust control and construction: Water supply tanks for dust suppression on roads, lots, and job sites.
  • Landscaping and turf care: Watering, spraying, and liquid nutrient applications for turf, trees, and plantings.
  • Municipal and public works: Water and chemical storage for street, park, and right of way maintenance.

Frequently Asked Questions

To keep algae out of a plastic water tank, limit sunlight and keep the tank clean. Our water storage tanks use UV resistant material to slow algae growth, and you can further reduce algae by choosing a black tank, cleaning the tank with a bleach solution three to four times a year, or using approved chlorine treatments.

Vertical plastic water tanks are designed for stationary storage, while horizontal plastic water tanks are built for transport. Vertical tanks have a small footprint and taller profile for permanent placement, and horizontal poly tanks use molded legs and a lower center of gravity so they can be mounted on trucks, trailers, and stands more safely.

Yes, many plastic water tanks are safe for drinking water when they are made from FDA compliant, food grade polyethylene and used correctly. Several of our plastic water tanks are rated for potable water, but you should always confirm the specification for your tank and follow local codes for drinking water storage, installation, cleaning, and maintenance.
