The Enduraplas 3100 gallon beige vertical water storage tank is a 103-inch-tall polyethylene tank on a 100 x 100 inch round footprint, built for bulk fresh-water storage where you need real capacity without the cost and permitting of steel or concrete. With a 1.1 specific-gravity rating, it carries 3,100 gallons of water comfortably and is rated for stored contents up to 28,439 pounds, leaving real headroom above the 25,854-pound weight of a full water load. If you have been searching for a beige vertical water storage tank from Enduraplas in the 3,000-gallon class, this is the size that does the work.
Will it work for your site
The numbers you need for layout and structural planning are all here. Footprint is a 100-inch (8.3-foot) diameter circle, the tank stands 103 inches tall, a full water fill weighs 25,854 pounds, and the wall is rated to carry contents up to 28,439 pounds. The full-water figure is the one to design your pad around: when this vertical storage tank is full, all 25,854 pounds land on roughly an 8.3-foot circle, so the soil and slab underneath have to carry it. The 1.1 specific-gravity rating means the tank wall is built for water and water-density liquids; if you are storing anything heavier than water, that rating is your ceiling. To match gallons to your draw-down and refill cycles before you commit, run the numbers through the Tank Sizing Calculator and the Tank Sizing Guide.
Pad and install
A water storage tank this heavy is only as stable as what it sits on. A full load of 25,854 pounds on a 100-inch footprint demands a flat, level, fully supporting base, typically a reinforced concrete pad sized for the load and the soil. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab and subgrade actually carry the weight. After the tank is set, run an acceptance fill before you put it into service; our hydrostatic test methodology covers the water-fill discipline, pad-settlement monitoring, fitting leak detection, and hold-time math that catch problems while they are still cheap to fix.
Common use and the mistake to avoid
This size is a workhorse for rural and remote water storage, fire-water reserves, and water-reuse trains where you are aggregating grey water, rainwater, or HVAC condensate into quality-banded storage. If fire protection is the job, read the fire-water reservoir tank design guide for NFPA 22 sizing and cold-climate freeze protection; for reuse layouts see the industrial water reuse tank topology guide. The mistake to avoid: this is a water tank rated to 1.1 specific gravity, not a chemical tank. Do not put a liquid denser than water into it on the assumption that it is big and it is poly; the wall thickness is engineered to the 1.1 rating, and exceeding it shortens tank life. Confirm fitting placement and outlet locations against the technical drawing on this page before you plumb it.
