A 2500 gallon black vertical water tank, 98 inches across and 86 inches tall
The Norwesco 2500 gallon plastic water storage tank, part number 42954, is a black polyethylene vertical tank 98 inches in diameter and 86 inches tall, weighing 340 lb empty. It comes with a 2 inch polypropylene female NPT bulkhead fitting as the outlet, a 1-1/2 inch polypropylene female NPT bulkhead fitting as the inlet, and a 16 inch threaded vented manway on top. Norwesco rates it at 1.0 specific gravity, which means water and liquids no heavier than water; 2500 gallons of water weighs 20,850 lb. The resin is FDA compliant, Norwesco lists the tank as NSF 61 for drinking water contact, the service limit is 120 F, and the warranty is 3 years. Black blocks light, which keeps algae down in stored water.

Where this shape earns its place
Two and a half thousand gallons is the size a household on a slow well buys to stop thinking about the well, the size a rainwater system needs to carry a dry month, and a common fire reserve on a rural lot. This shell is the lower, wider way to hold it: 98 inches across and only 86 inches tall, so the manway is reached from a step and the tank sits below most eaves and fence lines. Our complete buyers guide to this 2500 gallon black tank covers the trade against the taller 2500 gallon shells. For a fire reserve, the fire water reservoir guide for rural and remote sites covers sizing, the draft connection and freeze protection. For grey water, rainwater and condensate storage, read the water reuse storage guide.
Full, the tank carries 20,850 lb of water on a 98 inch circle, and the floor of a rotomolded tank bears on everything it touches. The pad must be flat, level and continuous under the whole base, extended past the rim rather than cut to it, and drained so overflow cannot wash out an edge. Band or strap the tank while it is empty, before the wind finds it, and re-check the bands after the first fill and the first storm. Leave room to walk all the way round. Check the number before you commit: run 2500 gallons against your real draw and refill interval in the tank sizing calculator, and take the reserve and freeboard allowances from the tank sizing guide.
Openings and fittings
- Outlet. A 2 inch polypropylene female NPT bulkhead fitting, factory installed low in the wall. Thread your valve into it and support the valve and the first length of pipe separately so the tank wall carries water, not plumbing.
- Inlet. A 1-1/2 inch polypropylene female NPT bulkhead fitting for the fill line.
- Manway. A 16 inch threaded vented manway on top for filling, a float switch, inspection and cleaning. The vent lets the tank breathe as the level changes; never seal it.
- Drawing. Norwesco's drawing for this tank is linked under Technical Drawing on this page and shows where the inlet and outlet sit so the pipe runs can be laid out before delivery.

The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP, or request a written quote if the job needs paperwork. Have two people or a forklift at the tailgate, and never lift by the manway. Check the part number against 42954 on the bill of lading, walk round the tank for transit damage before the driver leaves, and fill it with water the first time.
