The Enduraplas 5000 Gallon Black Vertical Storage Tank (SKU THV05000B) is a polyethylene vertical storage tank built for high-volume bulk water and liquid storage. It stands 150 inches tall on a 110 x 110 inch footprint, holding 5,000 gallons in a single upright column. The black resin blocks light to discourage algae growth, which makes it a practical choice for outdoor rainwater, process-water, and fire-reserve service where you need a large vessel that keeps its footprint tight.
Will it hold your water and how much will it weigh?
Filled with water, this tank carries roughly 41,700 lb of contents, so the pad and foundation below it have to be engineered for that load, not just the empty shell. The tank is rated to a 1.9 specific gravity, giving a maximum rated contents weight of about 79,230 lb for denser liquids up to that SG. That 1.9 rating is generous headroom over water (SG 1.0) and leaves real margin for heavier solutions, but always size your base to the actual weight of the liquid you plan to store. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm this 5000 vertical tank fits your volume and refill cycle before you buy.
Foundation and site planning
A vertical storage tank this size lives or dies by its base. Design the slab for worst-case loading, not just water: at the full 1.9 SG rating that means the 79,230 lb ceiling, while a straight water fill sits at 41,700 lb. Either way it needs a level, continuously supported concrete pad. Our guide to concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab under your tank is not the weak link. For rural fire-protection and remote-site reservoirs, our write-up on fire-water reservoir tank design covers NFPA 22 sizing and cold-climate freeze protection, both directly relevant to a 5,000 gallon black poly tank held in reserve.
The mistake to avoid
Confirm your fitting and outlet plumbing against the technical drawing on this page before you commit to a plumbing layout. The most common error on a tank this large is underbuilding the foundation or assuming the empty-tank footprint tells the whole story, it does not once 41,700 lb of water is inside. For grey-water, rainwater, and HVAC condensate aggregation setups where this tank often anchors the storage train, see our guide on industrial water reuse tank topology.
