The Enduraplas 870 Gallon Plastic Vertical Liquid Storage Tank (SKU THV00870) is a straight-wall vertical polyethylene tank built for above-ground bulk water storage, backed by verified launch dimensions: 78 inches tall on a 60-inch diameter, rated at 870 gallons. If you are sizing a storage train for water backup, irrigation, rainwater or reuse capture, run the numbers through our Tank Sizing Calculator and cross-check the approach in our Tank Sizing Guide before you commit to a footprint.
Will it work for your site
This is a vertical storage tank with a 60-inch diameter and a 78-inch overall height. The round tank seats inside a 60 x 60 inch square pad envelope, so it holds a compact footprint without the sprawl of a low-profile tank. Fitting count, outlet size and any bulkhead or gasket material are not published in this listing, so confirm the exact fitting layout against the technical drawing on this page and use those verified dimensions when you lay out the pad, plumbing runs and any tie-down or containment.
The weight number that decides your pad
Filled with water, this tank carries roughly 7,256 pounds. That full-water weight is the load your foundation has to hold, not the empty tank weight, and it is where most above-ground installs go wrong. A vertical tank on a circular footprint inside a 60 x 60 inch pad concentrates that load, so the base has to be flat, level and rated for it. Our guide to concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that base right. If this tank is going into private fire-protection service, the NFPA 22 sizing discipline guide covers reservoir sizing and cold-climate freeze protection.
The mistake to avoid
This is a water-service vertical tank, and its specific-gravity rating is not published in this listing. Before you store anything heavier than water or any chemical, call us to confirm the wall rating and resin — a tank sized for water can be undersized for a denser liquid. Vertical tanks also fail first at the vapor-saturated headspace above the liquid line, not below it; our breakdown of HDPE wall thickness at the headspace explains why liquid-side inspection misses it. For grey-water, rainwater or condensate reuse layouts, see our industrial water reuse tank topology guide.
