The Enduraplas 5050 gallon vertical liquid storage tank (SKU THV05050FG) is a beige polyethylene bulk-water vessel built for high-volume above-ground storage. It stands 120 inches tall inside a 120 x 120 inch bounding footprint, so a single vertical tank holds a full 5,050 gallons in a compact round pad area. If you are sizing a reservoir for rural fire-water reserve, irrigation supply, industrial water reuse, or general bulk water buffering, this is the tank that carries the volume without ganging together multiple smaller vessels.
Will it work for your site?
The controlling numbers are the footprint and the full-water weight. Filled to 5,050 gallons of water, this tank weighs about 42,117 pounds. That load lives on a roughly 120-inch (10-foot) diameter base circle, so the pad underneath it is not optional engineering — it has to carry better than 21 tons distributed across that circle. Plan the pad before the tank arrives. Our concrete pad sizing guide walks the ACI 360R-10 framework for above-ground poly tanks, and the Tank Sizing Calculator and Tank Sizing Guide help confirm 5,050 gallons is the right capacity for your draw and refill cycle. Confirm the exact fitting and outlet layout against the technical drawing on this page before you set the plumbing.
Fire-water, reuse, and cold-climate service
At this volume the tank does real work as a stored-water reserve. For rural and remote fire protection, our fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate installs. For grey-water, rainwater, and HVAC condensate aggregation, the industrial water reuse topology guide shows where a 5,050-gallon vertical fits in a quality-banded storage train.
The mistake to avoid
This tank is spec'd for water. It carries no specific-gravity rating in our data, which means it is a water-service vessel — not a chemical tank. Do not put a liquid heavier than water in it. Anything with a specific gravity above 1.0 (most concentrated chemicals, brines, and fertilizers) needs a tank rated for that weight, or the wall will be overstressed. The other quiet failure point on tall poly tanks is the vapor-saturated headspace above the liquid line, where wall stress and premature cracking originate; our HDPE wall-thickness guide explains the ASTM D1998 sizing logic and why liquid-side inspection misses it.
