Low Profile Water Tank Under Deck

Question: Hello. I am interested in a pillow tank under decks. I am looking for a pillow tank to use with a sprinkler system. I have an area under my deck where I can install it, but the available height would be only about 5 feet. I would like to store at least 2000 gallons. Is this something you think might be possible?

Answer: For use with a sprinkler system, the Gray Water Bladder is an excellent choice. These tanks are often used for non-potable water storage such as supplying rainwater or gray water to utilities and other water systems. In addition to your height, size for this tank will depend greatly on your available width and length under your deck.

Low Profiles

Among our listed capacities is a 2100 gallon tank. The standard dimensions for this size would be either:

  • 12 ft. L x 11 ft. W x 2.1 ft. H
  • 13 ft. L x 10 ft. W x 2.1 ft. H

Again, depending on the available width and length of your deck, this may be able to meet your storage capacity. If your deck area is slightly smaller than this, please feel free to send us your specific dimensions. These pillow tanks are highly flexible and may be able to be adjusted so that the height increased while the lengths and widths are decreased.

Collapsible Tank Fittings

  • Ball Valves
  • Caps
  • Pressure Relief Vents
  • Cam lock, Storz, or Threaded Adapters for Hose
