A 6600 gallon green vertical water tank, wide and under nine feet tall
The Norwesco 6600 gallon vertical water storage tank, part number 44119, is a green polyethylene tank 144 inches in diameter and 101 inches tall, weighing 998 lb empty. It is the low, wide way to store this much water: a tank that sits under a tall barn roof or a commercial canopy and blends into a tree line instead of standing above it. 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 22 inch threaded vented manway on top. It is rated for liquids up to 1.1 specific gravity, so it is a water tank; 6600 gallons of water weighs 55,044 lb. The resin is FDA compliant and UV stabilized, the service limit is 120 F, and Norwesco backs it with a 3 year warranty. Green is opaque like black, so it keeps light and algae out of the water while sitting quieter in a landscape.

Where the wide 6600 goes
This is a property reserve, a commercial rainwater tank or a fire supply. The low shape keeps the manway at 101 inches, reachable from a short ladder, and keeps the wind load down on an exposed site. The price is ground: a 144 inch circle, twelve feet across, that must sit on a flat, level, continuous slab carrying 55,044 lb of water plus the tank. The concrete pad sizing guide explains how to size that slab; at this weight nothing less than a slab is a good idea. For a rural fire supply, the fire water reservoir design guide covers the volumes departments look for, the draft connection they want to see and how to keep a big tank from freezing through. For rainwater and grey water reuse on a commercial roof, the water reuse storage guide covers how the trains are laid out and where a tank this size sits in them. Confirm the volume against the draw with the tank sizing calculator and the tank sizing guide.
Openings and fittings
- Outlet. A 2 inch polypropylene female NPT bulkhead fitting low in the wall. For a fire draft connection 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.
- Inlet. A 1-1/2 inch polypropylene female NPT bulkhead fitting for the fill line from a pump or a roof drain system.
- Manway. A 22 inch threaded vented manway on top, wide enough to work through, and the tank's vent.
- 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.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the fitting heights and the manway position for your pipe plan.

Shipping and receiving
A 144 inch tank is a wide load. It ships as an oversize shipment on a flatbed, freight class OVS, 998 lb, from Norwesco's Hanford, California plant, and 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. You need a telehandler, a loader with forks or a crane to take it off and set it; plan the lift before the truck arrives. At the tailgate, check the part number against 44119 on the bill of lading, walk round the shell for transit damage, set it on the slab, and run the water fill acceptance test before it carries anything else.
