Looking for tough, reliable water storage you can trust outdoors? This 4000‑gallon package includes two black, 2000‑gallon vertical tanks — giving you a powerful, flexible solution for farms, homesteads, or commercial setups. These tanks are built to resist sunlight and algae, making them ideal for outdoor use and long-term storage. Each tank is roughly 6.6 feet tall and 7.5 feet wide, so you can place them side‑by‑side or spread them out across your property.

Safe for Potable Water

Both tanks are made with BPA-free, FDA-approved HDPE and meet U.S. regulation 21CFR 177.1520, making them ideal for drinking water, gardens, livestock, or emergency storage.

Seamless, Leak-Free Design

Constructed via rotational molding in a one-piece design, these tanks eliminate seams and weak spots, giving you long-lasting reliability and minimal risk of leaks.



UV-Resistant, Algae-Reducing Color

The black exterior helps block sunlight, reducing algae growth and protecting water quality. The UV-resistant HDPE material ensures durability against sun exposure.

Includes Secure Lids & Bulkhead Fittings

Each tank comes with a 24‑inch threaded lid with breather valve and 2‑inch NPT fittings at both the top and bottom for easy plumbing connections.

  • Liftgate service may not be available in your area due to the size - please confirm when requesting a shipping quote
  • Commercial delivery address is recommended for lower shipping costs - residential still accepted

Please ensure:

  • The site is level and clear of obstructions
  • There's enough room for a freight truck to enter, unload, and exit safely

Delivery Instructions

  • Always inspect the tank before signing for delivery.
  • In the very rare occasion that a tank arrives damaged, so long as you follow our steps for handling damages when your tank arrives, we have you completely covered. We will send you a new tank at no additional charge.

Offloading Instructions

  • Liftgate service may not be available in your area due to the tank sizes - please confirm when requesting a shipping quote
  • If liftgate is unavailable, customer is responsible for unloading - drivers do not assist
  • For safest results, we recommend:
    • A forklift or tractor with forks
    • A pallet jack (if on a hard, flat surface)
  • While not officially recommended by us due to risk of damaging the tank or injury, some customers have been able to successfully offload each tank by hand without the above equipment with the help of 3-4 people
    • Keep in mind, each tank is a substantial 300 pounds and 7.5 feet wide
    • Each tank will need to be removed from the pallet on the truck, carefully lifted or rolled off the truck onto a soft surface, and then carefully rolled to the tank site
    • Again, we are not officially recommending this due to risk of damage or injury and strongly encourage the use of safe equipment for unloading
  • If you need a liftgate service, let us know during the quote process - we'll confirm if it is available for your address
