Chemical Compatibility & Specific Gravity
Polyethylene tanks have specific gravity ratings. SG 1.0 = water-rated. Higher SG = denser fluid handling. Always match the stored liquid's density to the tank's rating.
| Fluid | SG | Rating |
|---|---|---|
| Water, potable | 1.00 | Fully rated |
| Ag liquid fertilizer (10-34-0) | 1.40 | Within rating for SG ≥ 1.5 tanks |
| Saturated brine | 1.20 | Within rating |
| 12.5% sodium hypochlorite (bleach) | 1.20 | Within rating; UV exposure reduces bleach shelf life |
| Sulfuric acid, <30% | 1.25 | Within rating for XLPE tanks only; confirm with our team |
| Diesel fuel, motor oil | 0.85–0.90 | NOT rated — permeation concern |
| Concentrated acids (>30%) or strong solvents | varies | NOT rated — material attack |
For fluids not listed, call 866-418-1777 — we maintain a chemical compatibility chart that cross-references manufacturer material science with real field performance.
Typical Applications
- Rural potable water cistern
- Fire-suppression reserve
- Rainwater harvesting buried below frost line
Installation Checklist
- Backfill with pea gravel or coarse sand only — no native soil with rocks larger than 1 inch
- Fill the tank with water as you backfill to balance earth pressure
- Anchor with deadmen or a concrete ballast slab if your water table rises above the tank midline
- Bury to the depth specified in the tech drawing — do not bury deeper than rated
Shipping & Freight
Ships LTL. Expect a 53-foot delivery truck — confirm road-access clearance.
Warranty & Certifications
3-year limited full-replacement. Keep your One Source Plastics order confirmation — it's the warranty-claim trigger. Certifications on file: iapmo-certificate-2024-2029, csa-certificate, fda-resin-status-letter-2020.
When This Product Is the Wrong Choice
- Storing petroleum or solvents — HDPE permeation is too high for diesel, motor oil, or hydrocarbons
