The Enduraplas 870 Gallon Plastic Vertical Water Storage Tank (SKU TLV00870) is a vertical tank built for bulk and general water storage where you need real volume on a compact base. It stands 78 inches tall on a 60 x 60 inch footprint, holds 870 gallons, and comes fitted with a 16-inch lid up top for access and inspection plus a single 2-inch threaded fitting for plumbed fill or draw. Dimensions here are verified against the tank's launch spec, and you can confirm the fitting layout against the technical drawing on this page.
Will it work for your site?
This is a vertical water storage tank sized for rainwater collection, hauled-water reserves, irrigation supply, agricultural stock water, and rural fire-water reservoir duty. At full capacity the tank plus water weighs about 7,256 pounds, so the pad underneath it carries roughly three and a half tons on that 60 x 60 inch footprint. Plan the base accordingly — a full-water load like this belongs on an engineered concrete pad, not bare or uneven ground. Our concrete pad sizing guide walks through the ACI 360R-10 framework for slabs under above-ground poly tanks, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 870 gallons matches your draw-down and refill cycle before you buy.
Plan your plumbing and access around one 2-inch port
Read the fitting list closely before you design the connections: this tank carries one 16-inch lid and one 2-inch threaded outlet — that's it. Fill and draw share that single 2-inch port, or you fill through the lid and reserve the 2-inch fitting for draw. If you need dedicated fill and drain lines, plan for that now rather than assuming a second bung exists. Bring a 2-inch NPT camlock or bulkhead adapter to make the connection, and confirm the seal and gasket type at that outlet with us at 866-418-1777 before you plumb it. Access is a top-mounted consideration too: at 78 inches tall, the 16-inch lid sits about six and a half feet up, so inspection and cleanout need a ladder or a small platform. And because the empty tank is light on a 60 x 60 base, it will move in wind until it's filled or strapped — tie it down before you commission it.
The mistake to avoid
The most common miss on a tank this size is skipping the acceptance test and the pad prep. Before you put it into service, fill it with water and hold it — a hydrostatic test confirms the fittings seal, the pad isn't settling, and the tank is sound before it matters. If this is a fire-water reserve, size the volume against your NFPA 22 demand and cold-climate freeze protection rather than eyeballing it; our fire-water reservoir design guide covers that discipline. For reuse setups blending grey water, rainwater, or HVAC condensate, the water reuse topology guide shows how to band storage by quality.
