Vertical Plastic Water Storage Tanks

Poly Water Tanks for Homes, Farms, and Facilities

A poly water tank is a seamless, one-piece polyethylene tank that won't rust or corrode. Our Vertical Water Storage Tanks run from 22 to 15,500 gallons from Norwesco, Enduraplas, Custom Roto-Molding, Chem-Tainer and Peabody ProChem, and the drinking water models are molded from FDA-compliant polyethylene. Dark green or black walls block sunlight and help prevent algae growth. Ideal for residential, farm, or emergency use.

  • Safe for potable water
  • UV-resistant exterior
  • Algae-inhibiting design

Various sizes of blue and white poly water tanks for potable water storage in residential, commercial, and light industrial use.

Poly Water Tank Benefits

A dark tank wall keeps stored water clean: sunlight can't get in, so algae can't grow. A white or natural tank lets you see the water level, but keep it indoors or in the shade if it holds drinking water.

  • Algae-resistant exterior (green or black)
  • UV-resistant for long-term outdoor use
  • Potable water models from Norwesco, Enduraplas and Custom Roto-Molding
  • Tall, slim models for narrow spaces and short, wide models for low ceilings
