The Snyder Industries 1000 Gallon Vertical Storage Tank (SKU SII-5990100N42) is a cross-linked polyethylene (XLPE) vertical storage tank rated to 1.9 specific gravity in white. At 1.9 SG, the wall is engineered for liquids substantially heavier than water, which gives you real headroom on a 1000-gallon water reservoir and the option to store denser contents later without re-buying a tank. It stands 69" tall on a 74" x 74" footprint (74" diameter). Because 1000-gallon vertical tanks come in several height-to-diameter configurations, confirm THIS SKU's 74" diameter and 69" height against your slab and overhead clearance before you order.
Will it work for your site?
Full of water, expect roughly 8,340 lb on the pad, and the tank carries a max rated contents weight of 15,846 lb at its 1.9 SG rating. Use both numbers to size your foundation: this vertical storage tank needs a flat, level, fully supporting base across the entire 74" diameter footprint. If you're still narrowing capacity or pad dimensions, run the Tank Sizing Calculator and read the Tank Sizing Guide before you commit to a configuration.
Fittings and access
This XLPE vertical tank is configured with a flange outlet, an 18" PE threaded/vented top fitting, and a manway with 15" access for inspection, cleaning, and service. Check the technical drawing on this page for exact fitting locations and elevations before you plumb the inlet, outlet, and vent. Two things to verify up front: the flange gasket elastomer (the gasket, not just the tank resin, governs sealing and any future chemical service) and the vent sizing on the 18" PE threaded fitting against your fill and draw rates. Getting outlet height and vent placement right the first time avoids costly re-work.
Why the 1.9 SG XLPE build matters
For straight water storage this tank is well over-built, which is exactly why it holds up. The 1.9 SG cross-linked polyethylene chassis is the upgrade over a standard 1.0-1.5 SG water-only tank: it is the same tank to choose if you ever move to heavier liquids, so the headroom is bought once. That over-spec'd water-reservoir profile also suits rural and remote bulk-water and fire-protection storage; if that's your use case, the fire-water reservoir design guide walks through NFPA 22 sizing discipline. The mistake to avoid: don't treat XLPE and the 1.9 SG rating as a license to store anything. If your application ever shifts beyond water, confirm the contents against the resin and SG rating before you fill it.
