Cost Detail by Common Rental Size
The 1,000-gallon poly tank is the most-rented size for construction job sites, emergency backup water, and temporary agricultural use. United Rentals, Sunbelt, and BigRentz all carry them nationally. Delivery adds $75–$200 depending on your location. Buy vs. rent crossover: at $300–$500/month rental, buying a new 1,000-gallon tank for $350–$600 pays back in 1–2 months. If your need extends beyond 2 months, buying almost always wins.
5,000-gallon tanks require flatbed delivery — budget $150–$400 for transport each way. At this size, a crane or forklift may be needed for positioning, adding $200–$500 to setup cost. Buy vs. rent crossover: a new 5,000-gallon poly tank costs $1,800–$3,500 delivered. At $700/month rental plus delivery, buying pays back in 3–5 months. For seasonal or ongoing use, purchase is almost always the right call. See our 5,000-gallon tank guide for purchase options.
At 10,000 gallons you're in large poly or steel tank territory. Rain for Rent, United Rentals Fluid Solutions, and Adler Tank Rentals are the primary national sources at this scale. Mobilization fees ($400–$1,000+) often exceed one month's rent — factor these into your total cost calculation. Alternative at this size: a 21,000-gallon frac tank often rents for a similar monthly rate but gives you twice the capacity. See the frac tank section below. Purchase of a 10,000-gallon poly tank runs $2,000–$4,500; see our 10,000-gallon guide.
Frac tanks (also called baker tanks, frack tanks, or open-top storage tanks) hold 21,000 gallons (500 barrels) and are the best cost-per-gallon rental option for large temporary storage. Mobilization and demobilization (transport to/from site) typically runs $1,000–$3,000 per move — this is often larger than the first month's rental. Frac tank rental cost per day works out to roughly $30–$85/day on a month-long rental, or $100–$250/day for short-term. See our frac tank guide for full specs, dimensions, and capacity charts.
Vertical poly tanks are the most common rental type for construction, agricultural, and municipal applications. Key advantage over frac tanks: available in NSF/ANSI 61 potable-rated versions for drinking water applications. Delivery by flatbed or rollback truck — no crane required for tanks under 5,000 gallons. Poly tank rental companies include United Rentals, Sunbelt, National Rent-A-Fence (water division), and local agricultural co-ops. For commercial projects, search "poly tank rental [your city]" — regional suppliers often beat national rates by 20–30%.
Add-On Costs to Budget For
| Cost Item | Typical Range | Notes |
|---|---|---|
| Delivery (one way) | $75–$400 | Depends on distance from supplier depot and tank size; flatbed required for 5,000+ gal |
| Pickup / return (one way) | $75–$400 | Usually same rate as delivery; always confirmed in writing before signing |
| Damage waiver | 10–15% of rental rate | Optional but recommended; review what's covered — UV damage from improper siting may be excluded |
| Frac tank mobilization | $1,000–$3,000+ | Per move; often equals or exceeds 1–2 months' rent for short rentals |
| Pump (not included) | $60–$400 to buy or $50–$200/month to rent | Tanks arrive empty; getting water out requires a transfer pump |
| Cam-lock fittings | $20–$80 | Standard connection between tank outlet and pump/hose; usually not supplied |
| Tank cleaning on return | $50–$300 | Required if tank stored anything other than fresh water; ask before renting what condition is required |
| Minimum rental period | 1 week to 1 month minimum | A 3-day need often costs a full week; confirm minimum period before signing |
Where to Rent a Water Tank Near You
National Rental Companies
Local & Regional Sources (Often Better Pricing)
For poly tanks under 2,500 gallons, local suppliers frequently beat national chains by 20–30%:
- Agricultural co-ops and farm supply stores — Many rural co-ops have tanks available that aren't listed online. Call before assuming they don't rent.
- Irrigation supply companies — Often carry 250–2,500 gallon poly tanks for irrigation use, available for rent during off-season.
- Local plumbing and water treatment distributors — Some carry rental tanks for customers doing installations. Ask if they rent tanks they have in stock.
- Search strategy: "water tank rental [your city/county]" on Google Maps, then call the top 3 results for quotes before going to a national chain.

Rent vs. Buy: The Honest Breakdown
The rule is simple: rent for under 3 months, buy for longer. Here's the math at a few common sizes:
| Tank Size | Monthly Rental | Purchase Price | Breakeven Point | Verdict at 6 Months |
|---|---|---|---|---|
| 500 gallon | $250–$350 | $200–$500 | 1–2 months | Buy — saves $1,000+ |
| 1,000 gallon | $300–$500 | $350–$700 | 1–2 months | Buy — saves $1,200+ |
| 2,500 gallon | $400–$700 | $700–$1,500 | 2–3 months | Buy — saves $1,500+ |
| 5,000 gallon | $600–$1,000 | $1,800–$3,500 | 3–4 months | Buy — saves $1,000+ |
| 10,000 gallon | $1,000–$2,000 | $2,000–$5,000 | 2–4 months | Buy — saves $2,000+ |
| Frac tank (21,000 gal) | $800–$2,500 + mob | $15,000–$35,000 | 12–24 months | Rent unless permanent need |
| Purchase prices are new tank supply cost only, excluding foundation and installation. Rental rates exclude delivery. Frac tanks are almost always rented due to high purchase cost and specialized transport requirements. | ||||
What to Ask Before You Rent
- Is the tank potable-rated? If storing drinking water, confirm NSF/ANSI 61 certification explicitly. Not all rental tanks are food-grade.
- What fittings are included? Most tanks arrive bare. You may need to source your own hose fittings, cam-lock connectors, and pump separately.
- What is the delivery lead time? National companies typically need 3–7 business days. Emergencies may require a local supplier who can deliver same-day or next-day.
- Is there a minimum rental period? Many suppliers have 1-week or 1-month minimums. A 3-day need often costs a full week's rate.
- What are the return condition requirements? Most suppliers require the tank returned clean. Ask specifically what "clean" means — residue from non-water storage may require professional cleaning at your cost.
- What's the damage waiver policy? UV cracking from improper sun exposure, damage from forklift tines, and overfilling damage may or may not be covered. Read before signing.
- What is the mobilization fee for frac/baker tanks? This is separate from the monthly rental and is often the largest single cost for short-term large-tank rentals. Get it in writing before committing.

Frequently Asked Questions
National companies like United Rentals and Sunbelt typically need 3–7 business days for delivery scheduling. For emergency situations, local suppliers can sometimes deliver same-day or next-day — call around. BigRentz's online platform shows real-time availability from local providers and often surfaces faster options than calling national companies directly.
No — rental tanks are delivered empty. Filling the tank is your responsibility. For large tanks in areas without water access, some companies can arrange water delivery separately via water hauling truck, typically at $50–$150 per load depending on volume and distance.
Baker tanks and frac tanks are functionally the same thing — large portable steel storage tanks, typically 21,000 gallons (500 barrels). "Baker tank" is an older brand name (Baker Tank Company, now part of Clean Harbors) that became a generic term for the style, similar to how "frac tank" comes from hydraulic fracturing operations where they were originally used. Today the terms are used interchangeably. They're rectangular, open-top steel tanks with a sloped bottom for complete drainage, mounted on a trailer frame.
Yes — potable water tank rentals are standard for construction sites that need clean water for workers, dust suppression, or concrete curing. Specifically request a potable-rated, NSF/ANSI 61 certified tank when calling suppliers — not all rental tanks are rated for drinking water contact. Rain for Rent and United Rentals both maintain potable water tank inventory. Costs run slightly higher than non-potable tanks due to sanitization requirements between rentals.
If you have access to a municipal water supply at the job site, water cost is minimal — typically $0.003–$0.010 per gallon (less than a penny per gallon). Filling a 2,500-gallon tank from a hose costs roughly $8–$25 in water. If you need water delivered by truck, expect $100–$300 per truckload depending on volume and local hauling rates. Most construction sites simply connect to the site's temporary water service.
Water tank rentals are available in virtually every US market through national chains like United Rentals, Sunbelt, and BigRentz. For smaller poly tanks (under 2,500 gallons), local agricultural suppliers and farm co-ops often have better availability and pricing in rural areas. Search "water tank rental [your city or county]" on Google Maps and call the top 3–5 results — local suppliers frequently don't show up in national search results but carry tanks in their yard.
