The Norwesco 2500 gallon plastic water storage tank, part number 40631, is a black polyethylene vertical tank 95 inches in diameter and 91 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. The tank is rated for liquids up to 1.1 specific gravity, which is water and liquids close to it; 2500 gallons of water weighs 20,850 lb. The resin is FDA compliant and UV stabilized, the service limit is 120 F, and Norwesco backs it with a 3 year warranty. Black keeps light out and algae down.

Where this 2500 gallon shape fits
Norwesco holds 2500 gallons in three shells, and this is the middle one: 95 inches across and 91 inches tall, narrower than the widest version and a little taller than the lowest. It suits a pad that was poured for a smaller tank and a site where the manway can be reached from a step. The usual buyers are a household on a well that cannot keep up, a rainwater system meant to carry a dry month, a stock operation feeding troughs, and a rural lot that wants a fire reserve. Our complete buyers guide to this 95 by 91 inch tank compares the three shapes. For a fire reserve, the fire water reservoir guide for rural sites covers sizing and freeze protection; for reclaimed water, the water reuse storage guide.
Full, the tank stands 20,850 lb of water on a 95 inch circle. The base has to be flat, level and continuous under the whole floor, built past the rim rather than to it, and drained so overflow cannot undercut an edge. Band or strap the empty tank the day it lands, because an empty shell over seven feet tall moves in wind, and re-tension after the first fill. Leave a walking gap all round. Before you buy, 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 fitting carries water, not hardware.
- 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 moves; never seal it.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the inlet and outlet positions.

Shipping and receiving
The tank ships as oversize LTL freight from the nearest of Norwesco's plants, 95 by 95 by 91 inches and 340 lb on the truck. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP, or request a written quote for a job that needs paperwork. Have two people or a forklift at the tailgate, and never lift by the manway. Check the part number against 40631 on the bill of lading, walk round the tank for transit damage before the driver leaves, and fill it with water the first time.
