The mobilization trap: On a 2-week rental at $1,200/month, the tank costs $600. But mobilization ($1,200) + demobilization ($1,200) adds $2,400 — making the total project cost $3,000 for just 2 weeks. Short-term frac tank rentals are almost always more expensive per day than equivalent poly tank rentals, which have much lower transport costs.
Frac Tank vs Poly Tank — When Each Wins
| Factor | Frac Tank (21,000 gal) | Poly Tank (5,000–10,000 gal) |
|---|---|---|
| Tank capacity | 21,000 gallons (500 bbl) | 5,000–10,000 gallons |
| Monthly rental | $800–$2,500 | $600–$2,000 |
| Mobilization cost | $1,000–$3,000 | $150–$400 |
| Best for short-term (<1 month) | ❌ Mob cost dominates | ✅ Much lower transport cost |
| Best for long-term (>3 months) | ✅ Lowest cost per gallon | ✅ Also competitive |
| Open-top access | ✅ Yes — large opening | ❌ Closed top with fittings only |
| Potable water rated | ❌ Typically no | ✅ NSF-61 versions available |
| Positioning requires crane | ✅ Self-contained trailer | Sometimes for large sizes |
