Norwesco Water Storage Tanks

Norwesco is North America's top manufacturer of rotationally-molded polyethylene tanks. Norwesco water tanks are one-piece, seamless, watertight tanks used for agriculture, rainwater storage, and closed-top industrial and below-ground septic and cistern applications.

We carry both vertical above-ground rainwater storage tanks and horizontal below-ground holding tanks. The below-ground Norwesco water storage tanks are suitable for both potable and non-potable water and can be used for septic systems. All above-ground Norwesco storage tanks are available in black or dark green to help control the growth of algae.

Will Algae Grow In Clear Above-Ground Rainwater Storage Tanks?

Yes, algae does grow in clear above-ground rainwater storage tanks. Sunlight and still water are the perfect breeding ground for algae. Purchasing an opaque black or green Norwesco water tank is recommended to prevent the growth of algae. If you already own the clear tank, another option is to treat the water with an occasional dose of hydrogen peroxide or painting the tank’s exterior to inhibit the sun from penetrating the tank.

Can Norwesco Water Tanks Be Painted?

Yes, it is possible to paint Norwesco water tanks, but because paint doesn't adhere well to plastic, follow these recommendations for the best results:

  • Make sure the tank is in its permanent location before painting it. Moving it afterward will likely result in scratching.
  • Always use a bonding primer basecoat, then apply either latex or oil-based exterior paint.
  • Touch up the tank as needed to maintain the finish.
