The 1,100 gallon tank that fits under a deck
The Snyder WG42 is a green polyethylene water tank that holds 1,100 gallons in a shell 86 inches across and 53 inches tall, weighing 210 pounds. Low and wide is its whole idea: it slides under a deck, sits in a crawl space, or lines up along a barn wall below the windows, and its 18 inch manway is at chest height instead of at the top of a ladder. Threaded polypropylene fittings, a rating of 1.0 specific gravity for water and liquids no heavier, and a 3 year warranty.

Planning for a low tank
A low tank cannot tip and does not catch the wind, so the site work is about the floor rather than the straps: an 86 inch circle in full contact with a level base, carrying 9,174 pounds when full. The concrete pad sizing guide covers the slab or compacted pad for a wide, shallow load. Leave clearance above the manway for the lid and a hose, and leave a clear side for the outlet and a pump. The tank sizing calculator confirms 1,100 gallons against the draw before the base is built.
Choosing between the low and tall 1,100 gallon tanks
| Part | Gallons | Diameter x height | Empty weight |
|---|---|---|---|
| WG42 (this tank, green) | 1,100 | 86 x 53 in | 210 lb |
| WG44, bolted outlet | 1,100 | 86 x 53 in | 210 lb |
| WB43, black | 1,100 | 86 x 55 in | 210 lb |
| 32523 | 1,000 | 60 x 89 in | 157 lb |
| 32535 | 1,300 | 60 x 114 in | 194 lb |
The WG44 is the same tank with a stainless bolted outlet for a plumbed pump; the WB43 is the black low profile, 2 inches taller. The 60 inch tanks are for the site with floor space for a five foot circle and headroom to spare: the 32523 stands 89 inches and the 32535 stands 114, and both are lighter because a tall, narrow shell uses less resin for the volume.
Still deciding between these? Freight to your ZIP often settles it; the wider tanks ship differently. Or call 866-418-1777 and we will walk the table with you.
Fittings as shipped
- Inlet: 1-1/2 inch polypropylene female NPT bulkhead fitting.
- Outlet: 2 inch polypropylene female NPT bulkhead fitting, low on the sidewall.
- Access: 18 inch threaded, vented manway.
- Service limit: 120 F / 48 C.
Only 53 inches of head sits over the outlet, so a gravity feed from this tank is a slow one; plan a pump for anything beyond a hose bib. A green wall is opaque, and a sight tube teed off the outlet is the level gauge that costs the least and works in every light.
Jobs it is bought for
Rain cistern under a deck, well buffer in a crawl space, stock water along a fence, and one unit of the rural fire reserve the fire-water reservoir design guide describes. Ganged together they are the storage stage of a roof-water and condensate reuse train, per the industrial water reuse tank topology article; the tank sizing guide covers days of supply at a given draw.
Delivery day
The WG42 ships palletized as LTL freight (NMFC 156600-01) at a class rate; the freight cost estimator shows it for your ZIP, and the listed price is before freight. Two people carry 210 pounds off a liftgate and slide it into place. Fill it in stages the first time, watching the base and both fittings, as the hydrostatic test methodology guide lays out. Note the pad height and the outlet height on the site plan while the tape is out; the next pipe run will need both.
Freight and documents
Ships from: Lincoln, NE; Philippi, WV. LTL freight is quoted to your ZIP with the freight cost estimator or by phone at 866-418-1777. The listed price is before freight.
