A 2,500 gallon double wall chemical tank on a 102 inch base
The Snyder 5580000N45 is a double wall chemical storage tank: a 2,500 gallon white high density linear polyethylene primary rated for a specific gravity of 1.9, or 39,615 pounds of contents against 20,850 for water, standing inside its own secondary containment in a shell 102 inches across and 122 inches tall, weighing 1,420 pounds. It is bulk storage for a treatment plant's caustic, ferric or alum with the berm built in, for the plant that takes tanker loads and cannot pour a basin around an eight and a half foot circle. An 18 inch threaded, vented manway tops the primary, with a 3 year warranty.

A spill plan in one footprint
A single wall tank of regulated chemical needs a berm sized to its volume, and at 2,500 gallons that is a concrete basin, a sump, a drain valve that must stay closed, and a rain problem. The containment lives inside the outer shell, so the tank's 102 inch footprint is the entire footprint and the tank can stand inside an occupied building where a spill must never reach a floor drain; the SPCC 40 CFR 112 compliance walkthrough explains which spill-plan cases a double wall tank satisfies by itself. The rated chemistry for the resin is listed below; check the liquid at its concentration in the chemical compatibility database, because weight rating and chemical resistance are separate properties. The 2,500 gallon vertical tank buyers guide compares the single wall tanks at this volume, which is the right comparison only if a berm is already in place. The tank sizing calculator matches the volume to feed rate and delivery interval, and the tank sizing guide covers the reserve.
Grades on the 102 x 122 inch double wall, and the sizes beside it
| Part | Gallons | Diameter x height | Empty weight |
|---|---|---|---|
| 5580000N45 (this tank) | 2,500 | 102 x 122 in | 1,420 lb |
| 5580000N30 (sulfuric grade) | 2,500 | 102 x 122 in | 1,100 lb |
| 5580000N48 | 2,500 | 102 x 122 in | 1,100 lb |
| 5570000N48 | 2,000 | 102 x 103 in | 900 lb |
| 5590000N30 (sulfuric grade) | 3,000 | 102 x 142 in | 1,900 lb |
The N45 carries 320 more pounds of resin than the N30 and N48 in the same shell, the heaviest primary on this base; the N30 is the sulfuric acid grade. The 5570000N48 is the 2,000 gallon double wall, 19 inches shorter on the same base, and the 5590000N30 is the 3,000 gallon sulfuric-grade step up at 142 inches. All three sizes share the 102 inch footprint, so a slab poured for one takes the next.

Openings, and the second wall's job
- Access: 18 inch threaded, vented manway on the primary, 122 inches up; vent outside on caustic and acid service, fill through a dip tube, and size the vent for a tanker's unload rate.
- Outlet: through both walls as one penetration, flanged, with an expansion joint and the valve carried off the slab; order the fitting in the material the chemical calls for.
- Service limit: 120 F / 48 C.
Two levels need watching: the primary, with a sender chosen for the chemical, and the space between the walls, which serves as the leak alarm and gets a switch, a shift check at the port, and a weekly log entry. A wet interstice is a failed primary, and the tank is drained the same day. Keep the outer shell clear: nothing leaned on it, nothing bolted through it, nothing stored in the space. Full, the tank loads a 102 inch circle to 39,615 pounds at the rating: an engineered, full-contact slab under all of the floor, with straps holding the empty tank against wind.
The first delivery
The driver's pump can deliver faster than the manway vent can breathe, so the vent is sized for the unload rate or the fill goes through a dedicated top bulkhead with its own vent line. The fill pipe runs to the floor so caustic or coagulant does not free-fall and foam. Dense liquids heat up when diluted, so a tank topped off with water for a batch is filled water first, chemical second, never the other way. Somebody stands at the tank for the whole of the first delivery, checking the slab edge, the outlet fitting and the interstitial port as the level rises.
Jobs it is bought for
Caustic, coagulant and acid bulk storage at water systems that cannot build a berm, chemical storage inside occupied buildings, and any regulated liquid at plant scale at a site an inspector visits. One chemical to a tank, a label both inspectors can read, and the manway kept closed against vapor loss.
What the carrier needs from you
At 102 inches across and 122 inches long on the deck the 5580000N45 is oversize freight (NMFC 156600) on a flatbed at a lane rate; the freight cost estimator gives the flatbed number for your ZIP, and the listed price is before freight. A forklift with long forks or a small crane sets 1,420 pounds on the slab. Water-test the primary and hold it long enough to prove the interstice stays dry, then drain and dry the tank before the first delivery. Note the pad height and the outlet height on the site plan while the tape is out; the next pipe run will need both.
