This tank is a beast, but its weight of 199 pounds is manageable for two people to position. The bulkhead fittings are included, which saves you a trip to the hardware store. To see how it compares to other brands, explore our large water tank comparison article for more detailed insights. If you’re considering the 1550 gallon polyethylene tank worth buying for your specific needs, this is a top contender.

When you open the box, you receive the main Norwesco 1550 Gallon Water Tank – Black, the 16-inch lid, and the bulkhead fittings (both the 2-inch bottom outlet and the 1.5-inch top fitting). The tank arrives well-packed with cardboard and foam to prevent damage during shipping. The packaging is sturdy, and the tank itself shows no scuffs or cracks.
First impressions are positive: the polyethylene feels thick and dense, and the black color is consistent without any discoloration. The lid fits snugly, and the fittings are of good quality plastic with rubber gaskets. We would recommend buying additional hose adapters if you plan to connect to a pump, as these are not included. For a complete setup, you might also want a Norwesco tank vs other brands comparison to see what accessories you need. Overall, the unboxing experience suggests a product built for serious use.

Before you start, choose a level area that can bear the weight of 1,550 gallons of water (roughly 12,000 pounds). Concrete or compacted gravel is ideal. Position the tank on a solid base to prevent sinking. Remove the tank from the box and inspect it for damage.
Secure the lid by aligning it with the top opening and pressing down until it clicks. The lid provides a seal but is not airtight, which allows for proper ventilation. Ensure the bulkhead fittings are tightened securely by hand (no tools needed, use Teflon tape if you want extra leak protection).
For rainwater collection, connect a downspout diverter to the 1.5-inch top fitting. Use the 2-inch bottom outlet for attaching a hose or pump. The tank works best when you fill it gradually over several days to allow the base to settle. For emergencies, fill the tank from a hose or well pump.
Install a simple spigot at the bottom outlet for manual bucket filling. For irrigation, connect a submersible pump or a gravity-fed system. You can daisy-chain multiple tanks for increased capacity using coupling kits. Pro tip: use a first-flush diverter to keep debris out of the tank.
Check the lid seal periodically and clean the tank’s exterior with a mild soap solution. For algae control, add a few drops of bleach or use a specialized water treatment. Drain the tank completely once a year to clean the interior and inspect for sediment buildup.
If you notice a slow leak, check the bulkhead gaskets and retighten them. If the tank feels unstable, add a concrete paver base. For foul odors, empty the tank and scrub it with a vinegar solution. For a full troubleshooting guide, check out our water tank maintenance tips article.
After setup, you’ll quickly see why you should buy Norwesco 1550 gallon water tank for hassle-free water storage. The ease of installation makes it a strong candidate for anyone asking, “should I buy a Norwesco water tank?” The answer is yes, especially for large-scale projects.

We conducted a three-week testing period in our backyard. We filled the tank using a municipal water hose over two days and used it for drip irrigation on a vegetable garden. We also tested it for emergency use by simulating a power outage and using gravity-fed water.
The tank held water without any leaks, even when fully filled. The black exterior effectively blocked sunlight, and after three weeks, we noticed no algae growth. The water remained clear and odor-free. The tank’s structural integrity was impressive; it did not bulge or warp under the weight.
For irrigation, the 2-inch bottom outlet provided excellent flow for a standard garden hose. We filled a 5-gallon bucket in under a minute. During a simulated emergency, we used the tank as a backup water supply for drinking and cooking (after boiling). It performed flawlessly. We also tested it in partial shade, and the water temperature stayed consistently cool.
Norwesco claims the tank is UV-stabilized. After three weeks in full sun, we saw no fading or cracking. The seamless design indeed prevents leaks. The only thing to note is that the tank is not airtight, so some evaporation is possible in dry climates. After extensive use, we can confirm it’s a 1550 gallon polyethylene tank worth buying for anyone needing reliable water storage. For a deeper comparison, see how it stacks up against other brands in our Norwesco vs Snyder water tank article.
Overall, the pros far outweigh the cons, especially for those looking for a long-term water storage solution. If you’re evaluating the Norwesco 1550 gallon tank pros cons, you’ll see the benefits are significant.
We compared this tank to two popular competitors: the Snyder Industries 1500-gallon tank and the Ace Roto-Mold 1600-gallon model. Here’s a quick comparison table:
| Feature | Norwesco 1550 | Snyder 1500 | Ace Roto-Mold 1600 |
|---|---|---|---|
| Capacity (Gallons) | 1550 | 1500 | 1600 |
| Material | Polyethylene | Polyethylene | Polyethylene |
| Color | Black (UV-stabilized) | Black (UV-stabilized) | Black (UV-stabilized) |
| Weight (lbs) | 199 | 185 | 210 |
| Lid Size | 16 inches | 15 inches | 18 inches |
| Bottom Outlet | 2 inches | 1.5 inches | 2 inches |
| Price | Competitive | Slightly higher | Similar range |
| Seams | None (one-piece) | Weld seam | None (one-piece) |
Choose the Norwesco tank if you want a seamless design that reduces leak risks, a larger lid for easier access, and a well-known brand with solid warranty support. It’s ideal for homeowners and preppers who need reliable water storage.
Consider the Snyder 1500 if you prefer a lighter tank by 14 pounds (better for frequent repositioning). The Ace Roto-Mold 1600 offers a slightly larger lid and a bit more capacity. However, the Norwesco’s balance of features and price makes it a strong performer in the best water tank for rainwater collection category.

Place the tank on a concrete pad or compacted gravel to prevent it from sinking or tilting when full. This improves structural integrity and extends the tank’s lifespan.
For rainwater collection, add a first-flush diverter to the inlet to prevent debris and contaminants from entering the tank. This keeps the water cleaner for longer.
Connect a submersible pump to the bottom outlet for pressurized water flow. This allows you to use the water for sprinklers, pressure washers, or indoor plumbing. For a quality pump, check out our recommended Norwesco tank vs other brands for pump compatibility ideas.
For bucket filling or gravity-feed irrigation, install a brass spigot directly to the bottom outlet. This is a cost-effective way to access water without a pump.
While the tank is UV-stabilized, placing it in partial shade can further reduce evaporation and keep water cooler. Avoid full exposure to extreme heat if possible.
Some areas have regulations for rainwater harvesting. Check local codes to ensure you are compliant with safety and environmental standards.
Drain and scrub the interior once a year with a diluted bleach solution to prevent sediment buildup and bacterial growth. This ensures the water stays safe for drinking.
