The Chem-Tainer 1250 Gallon PE Cylindrical Open Top Tank (SKU TC6984AA) is a 1,250-gallon natural white polyethylene open top tank built for above-ground bulk water storage where you need easy top access for filling, inspection, or dropping equipment inside.It stands 84 inches tall on a 69-inch round footprint, so plan your pad and overhead clearance around those numbers before delivery.This is a straightforward white open top tank for crews who want a large-capacity reservoir without a fixed fitting package locking them into one plumbing layout.

Will it work for your site?
The cylinder is 69 inches in diameter and 84 inches tall, sitting on a 69.0 x 69.0 inch footprint.Full of water, expect roughly 10,425 lb of contents load on your pad - that is the number your foundation has to carry for plain water service.The 2.0 specific gravity rating means the wall is rated to hold contents up to twice the density of water, putting the maximum rated contents weight near 20,850 lb.Because of that, this tank is over-built for plain water (2.0 SG): it is the same shell you would reach for if you later repurpose it for denser fluids up to 2x water density, so you are not capacity-limited by the wall rating.A continuously supported, level concrete pad sized to the full footprint is the right foundation - our guide to concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework.If you are still settling on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match volume to demand.
Open top design, fittings, and common uses
The open top configuration suits applications where you fill or draw from the top, monitor levels by eye, or need to lower equipment inside - water reservoirs, batch holding, and rainwater or process-water collection are common uses.This open top tank ships as a bare vessel: no outlets, bulkhead fittings, or gaskets are included in the listed configuration, so specify any drain or outlet penetration at order and we will confirm what can be added.It is also a flat-bottom tank, which drains and cleans differently than a cone bottom - if full drainage or solids handling matters for your process, compare it against our Chem-Tainer cone-bottom drainage guide before committing to flat-bottom.Building a reuse or aggregation system?The industrial water reuse tank topology guide covers how to band storage by quality and stage treatment, and for rural fire-protection reservoirs the fire-water reservoir tank design guide covers NFPA 22 sizing and freeze protection for cold climates.See the technical drawing on this page for dimensional detail before you cut a pad or order penetrations.
The mistake to avoid
The most common error with a large open top tank is treating the SG rating as a license to skip foundation work.A 2.0 SG rating describes what the wall can hold; it does not change the fact that 1,250 gallons of water alone is roughly 10,425 lb sitting on a 69-inch circle.Set it on a full-contact, level pad - never on bare soil, gravel high spots, or partial supports that concentrate load.The contents weights above are the in-service load on your pad, not the handling weight: the tank's empty shipping weight is on the technical drawing and your freight quote, so confirm it before arranging crane or forklift offload.And remember an open top tank is not sealed - it is not the right choice where you need a vented, closed system or protection from airborne contamination, and it should never be pressurized.
