6,900 gallons in black at 1.5 specific gravity, twelve and a half feet on a ten foot base
The Snyder 7140000C37-BLACK is a black polyethylene vertical storage tank, 120 inches across and 153 inches tall, holding 6,900 gallons at 1,300 pounds. It takes a tanker and a third on a ten foot circle, with the 18 inch threaded, vented manway at nearly thirteen feet, and the black wall keeps light out of a load that size: water stays clear of algae through a whole summer, and a light-sensitive chemical keeps its strength. Its wall is rated for a specific gravity of 1.5, or 86,319 pounds of contents against 57,546 for water, so it holds brine, fertilizer solution and coagulant as delivered as well as water. A 3 inch polypropylene female NPT bulkhead outlet, a 3 year warranty, and freight at class 300 from Lincoln, Nebraska or Philippi, West Virginia.

A tall black tank, and what that asks of the site
Black polyethylene absorbs the ultraviolet that ages a white wall and passes no light to the liquid; it runs warmer in the sun than a white tank, which argues for the shade side of a building if the liquid must stay cool, and it shows no level line, so the sender does that work on a tank nobody climbs to look into. Full at the rating it puts 86,319 pounds on a 120 inch circle: a slab designed to the concrete pad sizing guide that bears the whole floor, ringed by a berm sized to the tank when the liquid is regulated, with the empty tank strapped against wind before the first fill, because thirteen feet of empty polyethylene on a ten foot base is a sail. The tank sizing calculator turns feed rate and delivery interval into a volume, and the tank sizing guide covers the reserve to leave in the bottom.
The 120 x 153 inch tank in its grades, and the 6,600 and 7,000 beside it
| Part | Gallons | Diameter x height | Empty weight |
|---|---|---|---|
| 7140000C37-BLACK (this tank, black, 1.5 SG) | 6,900 | 120 x 153 in | 1,300 lb |
| 7140000C26 | 6,900 | 120 x 153 in | 1,300 lb |
| 7140000C34 | 6,900 | 120 x 153 in | 1,300 lb |
| 5300400N40 (tall) | 6,600 | 120 x 158 in | 1,900 lb |
| 5300700N40 (low) | 7,000 | 142 x 122 in | 1,400 lb |
The 5300400N40 stands 6,600 gallons on this base five inches taller in the heavier chemical wall, and the 5300700N40 lays 7,000 gallons down to 122 inches on a 142 inch base for a lower roof.

The 3 inch outlet and the vent above it
- Outlet: 3 inch polypropylene female NPT bulkhead fitting, at the base; a flanged transition, a flexible connector between the bulkhead and hard pipe, and the valve supported off the pad in the material the liquid calls for.
- Access: 18 inch threaded, vented manway, 153 inches up; a platform with a rail, not a ladder, for anyone who opens it. Fill through a dip tube, vent outside on anything that fumes, and size the vent for the delivery pump, because a tanker's pump moves air faster than a stock vent passes it.
- Service limit: 120 F / 48 C.
A 3 inch outlet fills a pumper's suction or a sprayer's tank at a rate a 2 inch fitting cannot, and drains a full tank in a working shift. Nearly thirteen feet of liquid above it is a strong flooded suction for any pump; set the pump below the outlet so gravity primes it, with a low-level float to stop it before it draws air. A sender read at ground level is not optional on a black tank this tall. Freeze protection goes on the valve and the first pipe run, not the tank; the body ices from the top down and shrugs it off.
Who buys a black 6,900
Liquid fertilizer at a farm co-op where the tank stands in the open, coagulant at a water plant, a rain cistern under a large roof, water storage in full sun where algae is the enemy, and a fire reserve of the kind the fire-water reservoir design guide describes, where the 3 inch outlet earns its place. Several are the storage stage of a reuse system for roof water and condensate, per the industrial water reuse tank topology article, where the dark wall keeps the stored water from turning green.
From Lincoln or Philippi, and standing it up
The 7140000C37-BLACK ships from Lincoln, Nebraska or Philippi, West Virginia, whichever is nearer, as freight at class 300 as the sheet lists it; at 120 inches across and 153 long on the deck it is a permitted load, and the freight cost estimator prices the lane to your ZIP, with the listed price before freight. A crane stands 1,300 pounds up with straps under the body, never through the manway. Fill it to the manway once, hold it, and check the outlet fitting and the pad edge before the pump goes on; on a chemical, drain and dry before the connection is made, and the log takes the date and strength of every load after that. Mark the vent and the outlet on the outside of the shell so nobody caps the wrong one in the dark.
