10,500 gallons of chemical storage at 1.9 specific gravity
The Snyder 5330100N45 is a white high density linear polyethylene vertical chemical storage tank, 142 inches across and 169 inches tall, holding 10,500 gallons at 4,000 pounds. Its wall is rated for a specific gravity of 1.9, or 166,383 pounds of contents against 87,570 for water, and 4,000 pounds of resin is the heaviest linear wall on this base, for a plant's bulk caustic, ferric or coagulant that will be filled from tankers for decades. An 18 inch manway on top, and it ships as oversize freight.

Two tankers behind the heavy wall
A 1.9 specific gravity wall is sized for a liquid nearly twice as dense as water, the class ferric chloride at strength and the heavy brines fall in, and a tank of two tanker loads lets a plant take a full delivery with a full reserve still in the bottom. The chemistry list below is what the resin is rated for; check the liquid at its concentration in the chemical compatibility database, because density rating and chemical resistance are decided separately. A single wall tank of regulated chemical needs a berm sized to its volume; the Snyder Captor 110 percent containment comparison covers when a double wall tank is the cleaner answer than a basin. The tank sizing calculator turns feed rate and delivery interval into a volume, and the tank sizing guide covers the reserve.
Grades on the 142 x 169 inch tank, and the sizes beside it
| Part | Gallons | Diameter x height | Empty weight |
|---|---|---|---|
| 5330100N45 (this tank, 1.9 SG) | 10,500 | 142 x 169 in | 4,000 lb |
| 5330000N30 (sulfuric grade, 1.9 SG) | 10,500 | 142 x 169 in | 4,000 lb |
| 5330000N45 (1.9 SG, ASTM certified) | 10,500 | 142 x 169 in | 3,100 lb |
| 5330100N39 (1.35 SG) | 10,500 | 142 x 169 in | 2,500 lb |
| 5330300N33 (black, 1.35 SG, ASTM certified) | 10,500 | 143 x 179 in | 2,500 lb |
| 1006400N52 (double wall, 1.9 SG) | 8,700 | 142 x 197 in | 6,000 lb |
| 5350000N33 | 12,000 | 142 x 198 in | 3,100 lb |
The 5330000N30 is the sulfuric acid resin at this same weight and rating, and the certified 5330000N45 is the lighter 1.9 wall. The 5330100N39 and the black 5330300N33 are the 1.35 walls, 1,500 pounds lighter, for water and brine. The 1006400N52 is the double wall for a site with no berm, 8,700 gallons at 197 inches, and the 5350000N33 is the 12,000 gallon step up at 198 inches.

Openings, sampling and labels
- Access: 18 inch manway, 169 inches up; fill down a dip tube, run the vent outside on caustic and acid, and size it for the unload rate.
- Outlet: tell us the chemical when ordering and the bulkhead fitting is matched to it; a flanged transition, an expansion joint, and a valve supported off the slab.
- Service limit: 120 F / 48 C.
Three practices make a bulk chemical tank a safe one. Choose the level sender for the chemical with the level gauge selection guide; a sender read at ground level keeps everyone off the platform. Draw samples that represent the tank and not its stratified top, per the bulk tank chemical sampling protocol; fourteen feet of caustic stratifies, and a sample from the top tells you about the top. And label it so the fire inspector and the workplace inspector read the same thing, NFPA 704 diamond and GHS pictograms reconciled as the tank label and signage compliance guide describes, at a height a person on the ground can read.
The slab and the straps
Full, the tank loads a 142 inch circle to 166,383 pounds at the rating, and a rotationally molded floor bears on the whole pad, so the pad is what matters: an engineered slab in full contact under the entire floor, screeded flat, with no pipe trench or drain crossing under it, inside a berm sized to the tank. The empty tank is strapped against wind, and the straps go slack once the tank is full and its own weight anchors it. The platform at the manway stands on its own footings, not hung from the tank.
Filling from a tanker
Unloading a tanker pushes air out faster than a stock manway vent can pass it; size the vent for that rate, or fill through a dedicated top bulkhead vented separately. Run the fill pipe to the floor so caustic or coagulant does not free-fall and foam. Diluting a dense chemical makes heat, so a batch is built water first and chemical second, never the reverse. The first delivery into a new tank is watched from start to finish, with the slab edge and the outlet fitting checked as the level climbs, and from then on each load is logged by date and strength; with this much in the tank, the log is the stock count.
Where you will find one
Caustic, ferric and coagulant bulk storage at large water and wastewater plants with a berm, dense process chemicals at industrial sites that take tanker deliveries, and any regulated liquid at plant scale at a site an inspector visits. Give it one chemical, a label that satisfies both inspectors, and a closed manway.

Shipping the tank
At 142 inches across and 169 inches long on the deck the 5330100N45 is oversize freight (NMFC 156600) on a flatbed at a lane rate, with an escort on most routes; the freight cost estimator prices it for your ZIP, and the listed price is before freight. A crane sets 4,000 pounds upright on the slab. Prove it with water to the manway and a hold, and check the outlet fitting, before the first load of chemical. Walk the base after the first hard rain; a pad that shifts shows it at the edge first.
