1000 Gallon Tanks

Shop 1,000 gallon tanks from the same OEM lines the big distributors carry — Norwesco, Snyder Industries, Chem-Tainer, Enduraplas and Bushman — with the spec depth and freight transparency they don't give you. A 1,000-gallon vertical poly tank is the workhorse size for rainwater harvesting, potable and non-potable water storage, livestock and irrigation supply, bulk chemical batching, and emergency reserve.

What to know before you buy a 1,000 gallon tank

  • Material & rating: Most 1,000-gal vertical tanks are one-piece molded HDPE/HDLPE built to ASTM D1998, the majority rated to 1.9 specific gravity so they hold liquids heavier than water (fertilizers, many chemicals). Always confirm chemical compatibility and design SG for your product.
  • Footprint: A standard 1,000-gallon vertical runs roughly 64"–72" in diameter and 72"–82" tall depending on brand and profile. Low-profile and free-standing variants trade height for diameter — check the spec drawing on each product page.
  • Fittings: Sizing the bulkhead/outlet and lid to your pump and fill method matters more than the tank shell. Each product page lists outlet size, lid size and fitting options.

Every tank below lists at its BigCommerce list price; heavy LTL freight is quoted separately to your ZIP through our Freight Estimator or by phone at 866-418-1777 — our engineering team verifies resin, gasket and fitting compatibility before anything ships.
