Norwesco 6500 Gallon Black Vertical Storage Tank

Where 42411 usually ends up

This is the size a site buys when the drums and totes have become a handling problem and a full tank farm is more than the duty deserves. Typical work is buffering water ahead of a process, holding a recovered stream until there is enough of it to treat, and keeping a reserve on a property where supply is seasonal. Our article on banding reuse streams by quality is the one worth reading before the pipework is drawn, because what you decide to keep separate now is expensive to separate later. For a stored reserve on a remote site the reservoir design guidance covers the freeze question, and where a roof is the source, the first flush diverter sizing note explains how to keep the first minutes of a storm out of the tank.

Before any of that, put the duty through the volume calculator and read the sizing guide beside it. Buying more volume than the turnover supports is the standard mistake in this size bracket and it costs twice: once at purchase and again in maintenance.

What the sheet prints around this row

Two oddities are printed here exactly as the sheet issues them rather than smoothed over. The record's own shell reads 120 by 120 by 147 inches while three rows at the same capacity read 119 by 119 by 150; and two of those rows publish the same weight as each other under two different catalogue numbers. We print what the sheet says and draw nothing from it. The practical use of the table is the last row, where a near-identical gallon figure comes out of a 102 inch circle at 196 inches: a completely different demand on your ground and your headroom for the same nominal volume.

Four cells that decide the plumbing

Top opening

A 16 inch threaded vented manway. Start with the vent, because it is the air path that lets a bottom draw run at its natural rate on twelve feet of column; seal it and the tank works against itself. The size also sets the maintenance method for the life of the tank: hose, light and rinse, with no entry.

Bottom port

A 3 inch PP female NPT bulkhead fitting with a 2 inch reducer. The thread is female and in polypropylene, so the mating part is male, and the described reducer lets the line leave at 2 inches without a second hole in the wall. The fill side is a different story: the inlet cell is blank on this record, so nothing is published about how liquid gets in.

Temperature cell

120 F / 48 C, which is a ceiling for what you put in as well as for where the tank stands.

Grade cell

1.5, printed against a maximum contents weight of 81315 lb. The pair is read together and both belong to 42411 rather than to the 6500 gallon figure generally.

The record's own numbers, and what they do not cover

On a sheet where the same capacity appears in more than one shell, the part number is the only reliable handle, and the handle for this one is: 120 by 120 by 147 inches, 1346 lb empty, a grade line of 1.5, 81315 lb of maximum contents, a 16 inch vented opening, a 3 inch port with a reducer and a three year warranty cell. That is the record in full. Check it against a quotation line by line, because a capacity match is not a product match here.

What it does not cover is what happens under the tank and what happens on top of it. The pad is yours to specify, and a ten foot circle holding 54210 lb of water wants to be bedded evenly across the whole base rather than propped at the centre; our slab and pad framework sets out the sequence. Access to the manway is the other one: build the route to it when the pad is formed, not after the tank is full, because a top opening that is awkward to reach is a top opening nobody inspects.

One Texas origin and a slow first fill

Fairfield, Texas is the plant printed on this record and Texas is the single entry in the ships-from cell, which means the quote is one lane out of east Texas rather than a choice of routes. The mode cell reads LTL and the class cell reads 300; a 1346 lb tank ten feet across takes the room of a much heavier load, which is what that class is describing. Run the delivery address through the freight cost estimator and we will quote what the lane actually costs. The listed price is before freight.

Look inside before you commit water to it. With the tank upright and the 16 inch lid off, put your eyes to the opening in daylight and check the floor of the shell is clear of packing material and debris; it is a two minute job that saves a strainer and a pump.

Fill it in three stages with a pause between each, and write the level and the date on the commissioning sheet each time, so the tank has a history from its first day rather than from its first problem. A photo of the tank on its pad, full, on day one is worth keeping; it is the baseline every later inspection is compared against.
