Where to Rent a Water Tank
National Equipment Rental Companies
These companies have broad national coverage and standardized pricing. Their inventory is typically well-maintained and the rental process is straightforward.
- United Rentals — Largest equipment rental company in the US. Offers poly tanks from 500–10,000+ gallons in most markets. Online quoting available.
- Sunbelt Rentals — Similar national coverage with competitive pricing. Strong presence in the Southeast and Mountain West.
- BigRentz — Online rental marketplace that aggregates inventory from local and regional suppliers. Often the fastest way to compare pricing from multiple providers in your area simultaneously.
- H&E Equipment Services — Primarily in the South and Southeast. Good for large commercial tank rentals.
Regional and Local Suppliers
Local agricultural co-ops, farm supply stores, and regional equipment dealers often have poly tanks available for rent at lower rates than national chains — and frequently with faster delivery. Search "water tank rental [your city/county]" on Google Maps and call the top results for quotes. Many rural co-ops don't advertise online but have tanks sitting in their yard.
Tank Depot
Tank Depot's store network offers tank purchase and in some markets short-term rental programs. Their sales team can also refer you to regional distributors who rent.
Rent vs. Buy: When Each Makes Sense
Rent When:
- Your need is temporary — a construction project with a defined end date, an event, or emergency water supply
- You need delivery, setup, and pickup included — you don't have a way to transport a 500+ gallon tank yourself
- You're unsure what size you need long-term and want to test before committing
- You need a very large tank (5,000+ gallons) for a short period — purchase economics don't work below a few months
Buy When:
- You need the tank for more than 3–6 months — most tanks pay back their purchase price vs. rental cost within a year
- Your use is recurring (seasonal irrigation, ongoing livestock water, permanent backup supply)
- You have a way to transport or have the tank delivered to a permanent installation location
- You want control over the water quality inside the tank — rental tanks have had many previous users
| Scenario | Verdict | Reason |
|---|---|---|
| 3-month construction project | Rent | Monthly rental + delivery < purchase price for short term |
| Permanent farm water backup | Buy | Breaks even vs. rental in under 12 months |
| Annual outdoor event | Rent | 2 weeks/year of use doesn't justify buying |
| Emergency water after well failure | Rent first, buy later | Rent for immediate need; buy when you can plan the permanent solution |
| Firefighting water reserve | Buy | Permanent installation; reliability matters more than cost |
What to Ask Before You Rent
Don't just ask for the weekly rate. Get clear answers to these before signing anything:
- Is the tank potable-rated? If you're storing drinking water, confirm NSF/ANSI 61 or FDA-grade resin.
- What fittings are included? Most tanks come bare. You may need to supply your own hose fittings and pump connections.
- What's the delivery lead time? National companies can be 3–7 business days. Emergencies may require a local supplier who can deliver same-day.
- What's the damage policy? Damage waivers run 10–15% of the daily rate. Understand what's covered — UV cracking from improper placement may not be covered.
- Is there a minimum rental period? Many suppliers have 1-week or 1-month minimums. A 3-day rental might still cost you a full week's rate.
- What's the return condition requirement? Most require the tank returned clean. Budget for a tank cleaning before pickup if you stored anything other than potable water.

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 can show real-time availability from local providers and often has 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 an additional charge of $50–$150 per load depending on volume and distance.
Yes — temporary water storage for events is a common rental use case. Be clear with the provider about the intended use (potable vs. non-potable) so they provide the right tank. For event drinking water supply, confirm the tank is explicitly rated for potable use. Local health departments may require documentation for public events.
