Elkhart Plastics 3,000 Gallon Vertical Chemical Storage Tank – 1.5 SG
Built for liquids heavier than water, this 3,000 gallon tank is rated 1.5 specific gravity — it handles liquids weighing up to about 12.5 lb per gallon. It’s rotomolded in one seamless piece from UV-stabilized HDPE with heavier walls than a standard water tank, and ships with 1.5″ inlet and 2″ outlet fittings installed.

Which Specific Gravity Do I Need?
Specific gravity (SG) is how heavy a liquid is compared to water (8.33 lb/gal). Choose a tank rated at or above the SG of what you’re storing:
| 1.0 SG – Black | Water and liquids up to 8.3 lb/gal · Water tanks |
| 1.5 SG – White | Liquids up to 12.5 lb/gal · Chemical tanks |
| 1.9 SG – Light Blue | Liquids up to 15.8 lb/gal · Chemical tanks |
Installation Notes
- Set on a flat, level, smooth pad that fully supports the tank bottom.
- For atmospheric (vented) storage only — not a pressure vessel.
- Above-ground use only; not designed for burial.
- Use the molded tie-down locations in high-wind areas.
