4,900 gallons at 1.9 specific gravity on a 90 inch base, ASTM certified
The Snyder 5480000N45 is a white high density linear polyethylene vertical liquid storage tank, 90 inches across and 202 inches tall, holding 4,900 gallons at 2,000 pounds. Its wall is rated for a specific gravity of 1.9, or 77,645 pounds of contents against 40,866 for water, the chemical-grade wall for ferric chloride at strength, concentrated acids and the heavy brines, it is sold with ASTM certification for jobs that need the paper, and the seven and a half foot base puts a full tanker load on a pad smaller than the tanker. An 18 inch threaded, vented manway tops it, Snyder's 3 year warranty stands behind it, and it ships oversize.

The full-density wall, seventeen feet up
A 1.9 specific gravity wall is sized for a liquid nearly twice as dense as water, and 2,000 pounds of resin is what that takes on a tank seventeen feet tall, 550 pounds more than the certified 1.5 wall in this same shell. The certification is against ASTM D1998; the HDPE tank wall thickness guide explains the sizing logic and why a wall this tall is inspected from the top, in the headspace. Full, it puts 77,645 pounds on a 90 inch circle at the rating: an engineered slab with nothing but concrete under the whole floor, following the concrete pad sizing guide, inside a berm sized to the tank, with the empty tank strapped against wind and the manway reached from a fixed platform with a rail. The tank sizing calculator turns feed rate and delivery interval into a volume, and the tank sizing guide covers the reserve.
Grades on the 90 x 202 inch tank, and the sizes beside it
| Part | Gallons | Diameter x height | Empty weight |
|---|---|---|---|
| 5480000N45 (this tank, 1.9 SG, ASTM certified) | 4,900 | 90 x 202 in | 2,000 lb |
| 5480000N43 (1.5 SG, ASTM certified) | 4,900 | 90 x 202 in | 1,450 lb |
| 5480000N42 (XLPE, heavy wall) | 4,900 | 90 x 202 in | 2,000 lb |
| 5480000N40 (XLPE) | 4,900 | 90 x 202 in | 1,450 lb |
| 5480000N46 | 4,900 | 90 x 202 in | 1,450 lb |
| 8210000N40 (XLPE) | 4,650 | 102 x 154 in | 1,200 lb |
| 1002100C34 | 5,000 | 102 x 154 in | 950 lb |
The N43 is the certified 1.5 wall, 550 pounds lighter, for coagulants and brines that never approach this density; the N42 is the heavy cross-linked tank at this tank's weight for the densest oxidizers, and the N40 and N46 the lighter grades. The 8210000N40 and 1002100C34 hold 4,650 and 5,000 gallons on a 102 inch base at 154 inches, 48 inches shorter, for a site with a bigger pad and less height.

Ports
- Access: 18 inch threaded, vented manway, 202 inches up; on acid or caustic the vent goes outdoors, the fill goes down a dip tube, and the vent is sized to the tanker pump.
- 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.
- Listing: ASTM certification.
Read the level from the ground through a sender chosen for the chemical, not by climbing; leave the manway closed between fills to hold the vapor, and put the tank in shade if the chemical is light-sensitive. Regulated chemical in a single wall tank means a berm sized to the tank around it. Where it freezes, insulate or drain the outlet valve and the first length of pipe.
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. A fill pipe to the floor keeps caustic or coagulant from free-falling and foaming. A dense liquid heats when water is added to it, so a batch tank is filled with water before the chemical, never after. The first load into a new tank gets watched end to end, eyes on the slab edge and the outlet fitting while the level comes up, and each delivery after it is logged with its date and strength.
Where you will find one
Ferric and other dense coagulants at a plant with a berm and a small pad, acid feed for pH control, heavy brine at plant scale, dense process chemicals delivered by tanker, and water where the buyer wants the heaviest certified wall, including a fire reserve of the kind the fire-water reservoir design guide describes. One chemical, one tank, one label that both inspectors read the same way.
Shipping the tank
At 90 inches across and 202 inches long on the deck the 5480000N45 is oversize freight (NMFC 156600) on a flatbed at a lane rate; the freight cost estimator prices it for your ZIP, and the listed price is before freight. A crane sets 2,000 pounds upright on the slab; unloading is a forklift job, standing it is not. Fill it with water to the manway and hold it, drain and dry, and only then connect the chemical; the certification lives in the project file. Walk the base after the first hard rain; a pad that shifts shows it at the edge first.
