A thousand gallons, named for sodium hypochlorite
The Snyder 5990102N52 is a 1000 gallon double wall tank, listed on its sheet as a Sodium Hypochlorite (UV) Double Wall Tank, in opaque white at 81 inches long by 81 inches wide by 69 inches tall and 500 pounds empty. That is the maker's own name for the product and we repeat it exactly as it stands, including the bracketed part of the name; no concentration, no ultraviolet claim, no temperature beyond this sheet's own figure and no compatibility claim of any kind follows from it. The material field here is a numbered code rather than a plain material name, so no resin grade is printed from it: the tank is polyethylene and that is as far as the sheet goes. One capacity, one set of overall dimensions, one empty weight and one rating cover the whole assembly, with no separate inner tank figure, no separate outer containment figure, no annulus dimension and no containment percentage anywhere on it, so none appears below. The wall is rated at a specific gravity of 1.9, and the sheet gives 8,340 pounds for 1000 gallons of water at 8.34 pounds per gallon with 15,846 pounds of max contents. The opening is an 18 inch threaded vented manway, and the outlet field reads 1 Manway / Lid, which names an opening rather than a pipe size. The service limit is 120 F / 48 C, the warranty is a 3 Year Warranty, and freight is LTL at class 300 with no NMFC number.

Two plants, one class, and the freight on a low wide shipment
Take the lane first on this one, because it is the part of the decision most people leave until last and then pay for. The sheet lists two plants, Chowchilla, California and Lincoln, Nebraska, with California and Nebraska as the ship-from states, so a buyer in the plains, the Midwest or much of the South is on a reasonable lane out of Nebraska while the West and Southwest sit close to California. Freight is LTL at class 300, and the shipment is the tank itself at 81 by 81 by 69 inches and 500 pounds. That combination, a broad shipment at a modest weight, is what governs the cost: the lane is priced on the space the pallet occupies far more than on the pounds, which is why a wide low tank and a tall narrow one of similar volume can quote very differently to the same ZIP. Get your own number before the capacity is fixed. The same proportion decides how the tank behaves once it lands. Six feet nine each way and five feet nine tall is a low, broad object with its weight spread wide and its centre of gravity down, which is about as forgiving a thing to stand on a pad as this family offers. It will not thread through a building on a pallet truck, so the way in is a large shutter, a wall opening or an outdoor position; but at 69 inches the manway is within reach from a low platform, and there is no fall protection arrangement to design and then maintain for twenty years. The ground still has to be right. Flat, continuous and level across the whole 81 inch footprint, no rails, no timber left under it and nothing shimmed at a corner, because above it sits 8,340 pounds of water at 8.34 pounds per gallon and 15,846 pounds at the published 1.9 rating. Where the base is being poured for the tank, the concrete pad sizing guide for above-ground polyethylene tanks sets out the framework and its boundary. Containment arrives with the vessel rather than being built around it, which is the whole argument against a constructed bund at this volume; where a site has to document how its own containment arrangements are put together, our Snyder Captor double wall containment walkthrough lays out that framework. Nothing on this page is a claim that this part number satisfies any rule, and the sheet makes no such claim. Settle the volume honestly before you order: the usable capacity and the real headspace are not the nameplate figure, which is the subject of the double wall freeboard sizing guide, and your own turnover belongs in the tank sizing calculator with the freeboard discipline from the tank sizing guide.
Four 1000s, a 750 and an 1100
| Part | Gallons | Length x width x height | Empty weight |
|---|---|---|---|
| 5990102N52 (this tank, named Sodium Hypochlorite (UV), opaque white) | 1000 | 81 x 81 x 69 in | 500 lb |
| 5990102N30 (named Sulfuric Acid) | 1000 | 81 x 81 x 69 in | 500 lb |
| 5990102N48 (named ASTM XLPE Black) | 1000 | 81 x 81 x 69 in | 500 lb |
| 5990102N51 (named ASTM HDPE Black) | 1000 | 81 x 81 x 69 in | 500 lb |
| 5990902N30 (smaller, same proportions, named Sulfuric Acid) | 750 | 73 x 73 x 67 in | 390 lb |
| 5470000N48 (larger, narrow and tall, named ASTM XLPE Black Captor) | 1100 | 76 x 76 x 104 in | 650 lb |
Four listings share this exact 81 by 81 by 69 inch shell at the identical 500 pounds, and what separates them is the name, the colour and the material field the maker assigns. We print each name as the sheet spells it, brackets included, and explain none of them, because a name is not a specification and this page will not guess one out of a suffix. Describe the product and the strength to us and we will name the part number to order. Two of the four are black and two are not, and that is a daylight decision rather than a chemistry one: black keeps the light off the contents, opaque white lets an operator read the working level through the wall, which on a vessel whose only opening is a manway on top is very often the only level indication anybody has. The two other rows are the genuine size decision and they are not the same kind of change. The 750 gallon 5990902N30 is this tank scaled down and nothing else: 73 inches square and 67 inches tall at 390 pounds, so it is the same wide low shape with a quarter less volume, a slightly smaller shipment and the same easy reach. The 1100 gallon 5470000N48 is a different tank altogether, standing on a 76 inch plan and taking its volume upwards to 104 inches at 650 pounds. That row holds a tenth more than this one on a narrower plan, and it asks for real access in exchange. If the floor is scarce, price it and cost the platform in at the same time. If it is not, this 81 inch shell stays the easier tank to fill, inspect and clean for the whole of its life.

The eighteen inch manway is the fill point
- The fill opening: an 18 inch threaded vented manway on top, and it is the only opening this sheet publishes. That makes it the fill route, the inspection route and the cleaning route at the same time, so plan the fill connection, any suction and any instrument you want to drop in as one arrangement before the tank is set.
- Reaching it: the top of the shell is at 69 inches, which puts the manway within reach of a low platform rather than a fixed ladder. Bring the fill connection down to working level so a driver never climbs, and agree where that connection lives at the same time as the tank position.
- The vent: the manway is listed as vented, and that path is what protects the wall while a fill pushes air out and while a pump draws the level down. Keep it clear, look at it whenever the manway comes off, and never restrict it.
- The outlet field: it reads 1 Manway / Lid, which names an opening and not a pipe size, and the inlet field is blank. No outlet dimension, thread, bulkhead, flange or valve is published on this sheet and none is claimed here. Give us the duty and the line size and we will confirm what this part number carries before a pump is specified.
- The space between the walls: no monitoring port, gauge or alarm is published. That arrangement is specified separately, and at this volume it belongs in a written procedure with a schedule and a named owner.
- Structure: the sheet publishes no lifting lugs, no ladder lugs, no flange lines, no stand and no level device on this part number.
- Limits: 120 F / 48 C, a specific gravity rating of 1.9, and a 3 Year Warranty.
Tell us the product and its strength when you order. On a contained vessel the wetted parts are the only route a release can take, and they are chosen against the chemistry rather than against a default.
Disinfection rooms and dosing bays
A thousand contained gallons in a low wide shell goes to sites that take a full hose fill and dose continuously between them: disinfection and chemical feed rooms at municipal water and wastewater works, package and small municipal treatment plants, pool and aquatics plant rooms, food, beverage and dairy sanitising chemical stores, laundries and vehicle wash sites at scale, cooling tower and boiler house stations, and industrial process lines standing on a yard pad beside the building. This is the volume at which a site stops handling totes with a forklift entirely and starts buying at a bulk chemical cost per gallon instead, and the saving is counted per truck drop rather than per container. The opaque white shell earns its place in those rooms for one practical reason: the level can be read from the floor, and a level that can be read is a level that gets read before somebody orders the next load. Agree the receiving procedure when you buy the tank, not on the first fill: where the driver connects, who watches the level, and what the stop point is.
Five hundred pounds on an eighty-one inch pallet
Chowchilla, California and Lincoln, Nebraska are the two plants on this sheet, with California and Nebraska as the ship-from states. Freight is LTL at class 300 with no NMFC number, and the shipping size is given at 81 by 81 by 69 inches at 500 pounds. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. Five hundred pounds is light for the bulk, so the constraint at your end is width and not lifting capacity: a six foot nine shipment needs a proper opening, a straight run and turning room at the end, and that is the measurement to take at the narrowest point of the route rather than at the entrance. Take it under the base with forks, never by the manway, and set it on the finished, cured, level surface in its final position before a single pipe is connected. Fill it with clean water, hold the 8,340 pound load, and read the manway seal, the base all the way round and the pad beneath it. Drain it, let it dry, open the space between the walls, look in good light and write the date on the shell. While the water is still in it, use what this pale shell gives you and paint the outside at your working full level and at your stop level; from that day on every operator is reading against the same two lines instead of against a guess. The first fill is the only cheap time to find a problem, so do it in daylight with someone watching the base.
