The Enduraplas 6011 Gallon Black Vertical Water Storage Tank is a heavy-volume polyethylene vertical built for bulk water service where one large reservoir beats a bank of smaller ones. At 6011 gallons in a 144" x 144" footprint and standing 110" tall, it covers fire-water reserve, irrigation, rainwater aggregation, and process supply as a vertical water storage tank. The black resin blocks light to suppress algae growth, which is why black is the practical pick for water you intend to store for a while rather than turn over daily.
Will it work for your site
This vertical storage tank is rated to a specific gravity of 1.1, so it carries water (SG 1.0) with margin and handles slightly denser water-based contents up to that 1.1 ceiling. Plan your slab around the 144.0 x 144.0 inch footprint and the full load: water alone weighs roughly 50,132 lb when the tank is brimmed, and the tank is rated to a maximum contents weight of 55,145 lb. That is more than 25 tons on a single pad, so the foundation is not an afterthought. Size the tank to real demand before you commit using the Tank Sizing Calculator and the Tank Sizing Guide. One spec the pack does not lock for this listing is the fitting and gasket layout (fill, draw, drain, overflow, vent, manway) - confirm the configuration you need by quote before ordering; call 866-418-1777 and we will spec it to your install rather than guess. Vent and freeze protection are site-engineered too; see the Fire-Water guide below for how they fit a cold-climate stack.
Foundation and install discipline
A tank this heavy demands an engineered, level pad. Our Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide walks the ACI 360R-10 framework for getting the slab right at this weight class. After it is set and plumbed, do not skip acceptance testing: our Hydrostatic Test Methodology guide covers water-fill discipline, pad-settlement monitoring, and fitting leak detection so you catch a problem during a controlled fill rather than after the tank is in service. You can cross-check overall dimensions against the technical drawing on this page.
Where this tank earns its keep
For rural and remote fire protection, a reservoir this size anchors a private fire-water stack; see our Fire-Water Reservoir Tank Design guide for NFPA 22 sizing discipline and cold-climate freeze protection. If you are aggregating grey water, rainwater, or HVAC condensate, our Industrial Water Reuse Tank Topology guide shows how a bulk vertical storage tank fits a quality-banded reuse train.
The mistake to avoid
The most common error on a tank this large is under-building the foundation. Buyers spec the right capacity, then set 25-plus tons on a pad that is not flat, not thick enough, or not properly compacted, and the tank loads unevenly. Get the slab engineered to the full 55,145 lb rated load before the tank arrives. The second mistake is treating the 1.1 SG rating as a license to store anything denser than water without checking; this is a water storage tank, not a chemical tank. If your contents run heavier than 1.1 SG, call 866-418-1777 for a chemical-rated tank quote instead of pushing this one past its rating.
This 6011-gallon vertical ships LTL from the Enduraplas plant in Converse, TX, with freight quoted live to your ZIP. Because it ships from a single Texas origin, freight scales hard with distance on a 25-ton-class unit, so get your number early on the Freight Cost Estimator or call 866-418-1777 to lock in delivery. Stage offload equipment before the truck arrives - at 144" (12 ft) wide and 110" (just over 9 ft) tall, confirm gate width, crane reach, and pad clearance first, because at this weight you will not move it by hand.
