The Enduraplas 2100 Gallon Plastic Vertical Water Storage Tank in Black is a polyethylene vertical tank built for bulk water storage where you need real volume in a single footprint. At 2,100 gallons, this is the size buyers reach for when a smaller cone or utility tank runs dry too fast: rural fire-water reserve, irrigation supply, rainwater aggregation, hauled-water holding, or process make-up water. The black resin blocks light transmission, which slows photosynthetic algae growth in stored water compared with translucent tanks - it suppresses light-driven growth, it does not sanitize or treat the water. Below is what you need to confirm before you buy: how this vertical storage tank works for your job, how it ships, and the one sizing mistake to avoid.
Will this 2,100-gallon tank work for my site?
This is a vertical water storage tank in black polyethylene, rated at 2,100 gallons. The single number that drives every other decision here is full weight: filled with water, this tank carries roughly 17,514 lb. That is the load your pad, ground, and any structure underneath have to support, so plan the foundation around the full figure, not the empty tank. Because water runs about 8.3 lb per gallon, every 250 gallons you store adds roughly 2,085 lb to the pad - useful math if you are sizing for an intermediate fill level rather than a brimming tank. Use the Tank Sizing Calculator to confirm 2,100 gallons matches your draw-down and refill cycle, and the Tank Sizing Guide if you are choosing between this and a larger or smaller vertical.
How does it ship and what does freight cost?
A 2,100-gallon vertical tank ships LTL freight, not parcel, because of its size. This tank ships from Converse, TX (San Antonio area), and freight is quoted live to your ZIP code rather than baked into the listed price. Destinations in TX, OK, LA, AR, NM and the broader south-central corridor will generally quote the lowest LTL, while Northeast and West Coast points carry the longest haul. Run your ZIP through the Freight Cost Estimator for a real number before you order, or call us at 866-418-1777 and we will quote it for you. One note before you plumb it: the inlet, outlet, vent, and manway fitting configuration is not listed in our spec data for this SKU, so call 866-418-1777 to confirm the exact fitting and bulkhead layout before you order plumbing.
The mistake to avoid: build the pad for full weight
The most common error on a tank this size is sizing the foundation for the empty tank or for a partial fill. At full capacity this vertical carries about 17,514 lb sitting on its base, and that load has to land on a level, fully supporting surface. If you are pouring a concrete pad, our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework. Once it is set, the hydrostatic test methodology guide covers the water-fill acceptance step that catches pad settlement and fitting leaks before the tank goes into service.
Common applications for this size
At 2,100 gallons, this vertical storage tank fits several jobs where a single large reservoir beats multiple small ones. For rural and remote fire-protection reserve, our fire-water reservoir tank design guide covers NFPA 22 sizing and cold-climate freeze protection. If you are aggregating grey-water, rainwater, or HVAC condensate, the industrial water reuse tank topology guide shows how this tank fits a quality-banded storage train. You can also see the technical drawing on this page for the tank's profile.
