The Enduraplas 1200 Gallon Beige Vertical Water Storage Tank (SKU TLV01200BE) is a polyethylene vertical tank built for bulk water storage where you need real volume on a contained footprint. It holds a true 1,200 gallons on a 90 by 90 inch base and carries a 1.1 specific gravity rating - enough headroom for water and slightly denser water-based liquids without pushing the wall material past its design point. The beige color reduces light transmission to slow algae growth in outdoor water storage service, and at this size it is one of the workhorse formats people shop when they want a vertical storage tank that does not eat the whole yard.
Will this tank work for your site?
Start with the load math, because that is where most installs go wrong. Filled with water, this tank carries 10,008 pounds of contents. It is rated to a maximum contents weight of 11,009 pounds, and that 11,009 number - not the empty tank weight - is what your pad has to support. That is more than five tons of liquid sitting on a 90 by 90 inch footprint, so the ground under it does the heavy lifting. The 1.1 specific gravity rating is your ceiling: water is 1.0, so the tank tolerates liquids up to roughly 10 percent denser than water, and anything heavier than 1.1 SG needs a tank built for it - a margin you generally will not approach in plain water storage. If you are not certain this is the right capacity for your draw and refill cycle, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit. Confirm the exact height and footprint against the technical drawing on this page before you spec it into a low-clearance install - measure the real overhead and door clearance on your site against the drawing, not against an assumption.
Pad and install
A flat-bottom vertical tank only performs as well as the surface under it. The full load distributes to roughly 196 pounds per square foot across the 56 square foot base, and that pressure wants a level, continuous, full-contact pad - a settling edge or a void under the floor concentrates stress and is the most common cause of premature failure on tanks this size. Size and reinforce the pad properly before delivery; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting that number right. Once the tank is set and plumbed, prove the install with a controlled water fill and a pad-settlement check before you put it into service - our hydrostatic test methodology covers the fill discipline, hold-time math, and leak detection.
The mistake to avoid
The fitting and outlet layout on this tank is not detailed in our current data, so do not buy valves, bulkheads, gaskets, or adapters on an assumption. Call 866-418-1777 with the SKU (TLV01200BE) and we will confirm the inlet, outlet, and bulkhead positions and thread sizes against the OEM technical drawing before you order - matching the gasket and adapter to the actual fitting is the step that keeps you from ending up with parts that do not fit when the tank lands on your pad. For larger systems - fire reserve, reuse trains, multi-tank banks - our guides on fire-water reservoir design and industrial water reuse tank topology cover how a 1,200-gallon vertical fits into a banded storage stack.
This tank ships LTL freight from the Enduraplas plant in Converse, TX, quoted live to your ZIP. If you are in Texas, Oklahoma, or Louisiana, that origin usually means a shorter lane and a lower number. Get your exact freight from our Freight Cost Estimator or call 866-418-1777 and we will quote it for you - have your delivery ZIP and any access constraints (forklift, liftgate, limited-access site) ready so the quote matches your site.
