Snyder Industries 90 Gallon ASTM Black Heavy Duty Vertical Storage Tank

A squat, dark tank for the outdoor jobs

This tank suits the job that needs a modest supply kept clean outside: a water reserve for a cabin, a coop or a kennel; drinking water for a few head of stock; a rinse tank at an equipment wash-down; a fertilizer tank feeding an injector in a garden or a small orchard. At 41 inches tall and 34 inches across it sits low and steady, fits under a lean-to or a deck, and is easy to fence or cover. High density polyethylene handles water, most liquid fertilizers and many common chemicals, and the 1.9 rating lets it hold dense liquids such as brines. Snyder also makes this size with a cross-linked wall; if the liquid is aggressive, call us and we will tell you which one fits. Check anything other than water in our chemical compatibility guide first.

Mind the heat. The 120 F service limit applies to the liquid, and a black tank in full summer sun warms up, so give it shade on a hot site. Leave room at the top for the liquid to expand; our guide to freeboard and the volume you can actually use shows how much. And since a black wall hides the level, plan a float gauge, a sight tube or a dip stick.

What to check before you buy

1. Fittings. The outlet and lid on 5690100N51 are not listed on this page. Tell us the outlet size and height you need and we will confirm what comes on the tank.
2. Base. Up to about 1,426 lb on a 34 inch circle needs a flat, level, continuous surface. Our concrete pad sizing guide covers slabs; on soil, a bed of compacted fine gravel works for most small tanks.
3. Restraint. At 43 lb empty, a strong wind moves it. Strap it to a post or a frame.
4. The drawing. The technical drawing for 5690100N51 is linked under Technical Drawing on this page. Use it to plan the pipe run.

At the tailgate, check 5690100N51 on the bill of lading against the label on the tank, look the base and the top for dents or cracks, and write any damage on the bill before you sign. Rinse it, fill it with water, and check every fitting for a weep before it goes into service.
