6500 Gallon Plastic Water Storage Tank

Where a tall 6500 goes

This is a reserve for a property, a business or a fire supply, not a garden tank. At 150 inches, twelve and a half feet, it is the tallest thing in most yards, so it suits a site screened by a building or trees, or one where nobody minds. The height buys you a small footprint and a useful head of pressure at the outlet when the tank gravity feeds. It also means a fixed ladder for inspection and a float valve on the inlet line where it can be serviced from the ground. The 119 inch circle must sit on a flat, level, continuous slab carrying 54,210 lb of water plus the tank; the concrete pad sizing guide explains how to size it, and a tall tank is the case where a level slab matters most, because a lean that is invisible at the base is obvious at the top. A tall empty tank catches wind; strap it until the first fill. For a rural fire supply, the fire water reservoir design guide covers the volumes departments want, the draft connection and freeze protection. For rainwater and reuse on a commercial roof, start with the water reuse storage guide. Confirm the volume with the tank sizing calculator and the tank sizing guide.

Openings and fittings

1. Outlet. A 2 inch polypropylene female NPT bulkhead fitting low in the wall. For a fire draft or fast truck filling, 2 inches is on the slow side; tell us the flow you need before the tank ships. Support the valve and the pipe on their own.
2. Inlet. No separate inlet fitting is listed for this tank. Tell us how you plan to fill it and we will confirm the fill arrangement before it ships; many buyers fill through the manway or have a fitting added.
3. Manway. A 16 inch threaded vented manway on top, which is also the vent.
4. Rating. 1.1 specific gravity, a maximum of 9.18 lb per gallon. Water. Liquid fertilizers are heavier and need a tank rated 1.5 or higher. Keep contents under 120 F.
5. Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the outlet height and the manway position.

Shipping and receiving

The tank travels on its side, 150 by 119 by 119 inches, as an oversize load on a flatbed at freight class OVS, 1104 lb shipping weight, from Norwesco's Hanford, California plant. The carrier needs a site a flatbed can reach and turn in. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP, or request a written quote for the job file. You need a telehandler or a crane to lift it off and stand it up; plan the rigging and the slings before the truck arrives. At the tailgate, check the part number against 43876 on the bill of lading, walk round the shell for transit damage, stand it on the slab, and run the water fill acceptance test before it carries anything else.
