The Snyder Industries 1200 Gallon Vertical Water Storage Tank (SII-32531) is a green polyethylene vertical tank built for above-ground bulk water storage, standing 57" tall on an ~86" diameter round base. It carries a 1.0 specific gravity rating, which means it is sized for water and water-equivalent contents at standard density. Filled to its rated 1,200 gallons, the tank holds 10,008 lb of water, and that single number drives almost every install decision you will make below.
Will this tank work for your site?
This is a vertical storage tank on a round ~86" diameter base with a 57" overall height, so it fits low-clearance areas like pump houses, barns, and equipment sheds where taller verticals will not clear the roof line. That 57" height on an 86" diameter is a genuinely squat, low-profile vertical, so confirm the dimensions against your clearance and door openings before planning the set. The 1.0 specific gravity rating confirms it is engineered for water service: irrigation, livestock, rainwater holding, and fire-water reserve are all within its design density. Run your demand numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you commit, so the 1,200-gallon capacity matches your draw-down and refill cycle rather than your gut.
Foundation and the 10,008 lb question
A full 1200 gallon tank puts 10,008 lb onto a base that fits inside an 86 x 86 inch bounding box, so the pad underneath it is not an afterthought. Spread across that roughly 7,400-square-inch footprint, the water load alone works out to around 1.35 psi (about 195 psf) before you add the tank's own weight, and that load needs a level, continuously supported surface. Our concrete pad sizing guide walks through the ACI 360R-10 framework for sizing a pad to the 86 x 86 bounding box under a polyethylene vertical. Once the tank is set, fill it with water and follow our hydrostatic test methodology to confirm pad settlement, fitting seals, and hold-time before the tank goes into real service.
Fittings and built-for-water roles
Fitting configuration — outlet size, bulkhead, and vent — is not published in this listing, so confirm the outlet and any gasket selection by phone before you order, and match that gasket to your stored water and any downstream additives at the time of fitting spec. Beyond that, because this is a true water storage tank at 1.0 SG, it slots cleanly into specialized water duty. For rural and remote fire protection, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection for a vertical tank like this one. If you are aggregating grey-water, rainwater, or HVAC condensate, our water reuse topology guide shows where a 1,200-gallon vertical fits in a quality-banded storage train.
The mistake to avoid
The 1.0 specific gravity rating is the line you do not cross. This tank is built for water and water-density contents only — that is, liquids up to roughly water's 8.34 lb/gal. If your liquid is heavier than water, such as a brine or a chemical above water density, you need a higher-SG-rated tank, not this one, because exceeding the rating shortens wall life and risks failure under hydrostatic load. Call 866-418-1777 for a 1.5 or 1.9 SG-rated tank instead. Match the contents to the rating, not the capacity number.
