The Enduraplas 1200 Gallon Black Vertical Water Storage Tank (SKU TLV01200B) is a polyethylene vertical water tank built for bulk water storage where UV exposure and algae control matter. The black resin blocks light, which discourages algae growth in standing water, and at 1200 gallons it gives you serious capacity for rural and remote water reservoir duty. Before you set this tank, three numbers decide everything: how it works for your install, what it weighs full, and what it costs to ship to your ZIP. Here they are.
At a glance: 1200 gal · 60 in H × 90 in W × 90 in L · polyethylene, rated to 1.1 specific gravity · full water weight 10,008 lb · max rated contents weight 11,009 lb · bearing footprint 90.0 × 90.0 in · ships LTL from Converse, TX.
Does it work for your install?
This is a vertical water tank rated to 1.1 specific gravity, so it is sized for water and water-like contents up to that density. Denser or chemical fluids that exceed 1.1 SG need a higher-SG-rated tank, not this one; call 866-418-1777 and we will confirm the right tank for heavier service. Capacity is 1200 gallons, dimensions are 60 inches high by 90 inches wide by 90 inches long, and the build is polyethylene. At only 60 inches tall it slides under low clearances that taller verticals of the same volume cannot, but check your overhead room against the fill and vent fittings on top before delivery so a roof, eave, or doorway does not stop the install. Fitting and outlet positions, along with bulkhead and gasket sizing, come straight off the outlet callouts on the technical drawing on this page, so let that drawing be your authority for plumbing tie-ins and gasket selection. EPDM gaskets suit plain water service. To match this storage tank to your actual draw and refill needs, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit to a size.
Weight, pad, and the mistake to avoid
The single biggest mistake on a tank this size is under-building the foundation. Filled with water this vertical tank carries 10,008 pounds, and at its maximum rated contents weight it reaches 11,009 pounds, all bearing on a 90.0 x 90.0 inch footprint. That load demands a level, continuously supported pad. Pour or verify a slab sized for this weight using our Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide, which walks the ACI 360R-10 framework and the ACI 318 boundary. After setting and before putting the tank into service, run a controlled water-fill acceptance per our Hydrostatic Test Methodology guide to catch pad settlement and fitting leaks before the tank is in daily use.
Common applications
As a black vertical storage tank it suits rural and remote water reservoir duty, including fire-water reserve where light-blocking storage helps keep stored water clean. If you are building a private fire-protection reserve, our Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate aggregation, the Industrial Water Reuse Tank Topology guide shows how a tank like this fits into a banded reuse train.
Freight
This tank ships LTL freight from the Enduraplas plant in Converse, TX, with the cost quoted live to your ZIP code. Because LTL pricing depends on distance, liftgate, and limited-access surcharges, there is no flat number, so get yours with our Freight Cost Estimator, or call 866-418-1777 and we will quote it for you and help confirm this is the right vertical water storage tank for your site.
