Norwesco 4995 Gallon Light Blue Heavy Duty Vertical Storage Tank

Where it goes and what it holds

At 89 inches the top of the tank sits a little over seven feet up, within reach from a short step, and the 22 inch manway takes a larger float valve or a submersible pump and gives real cleaning access. The heavy duty wall is for liquids denser than water and for a tank that stays full year round; for plain water a lighter rated tank does the job. Check the liquid in our chemical compatibility guide before the first fill and keep it under 120 F. A full tank is more than twenty tons on a circle nearly twelve feet across, so the pad has to be flat, continuous and level under the entire base; our guide to concrete pad sizing for above ground polyethylene tanks sets out the slab. If the tank is a fire reserve, our guide to fire water reservoir design for rural and remote sites covers sizing and freeze protection, and the industrial water reuse storage guide covers reuse trains at this scale. For the volume itself, use the tank sizing calculator and tank sizing guide.

Openings and fittings

1. Outlet. A 3 inch polypropylene female NPT bulkhead fitting with a siphon tube, factory installed. The siphon tube reaches down inside the tank so the fitting can sit above the floor and still draw from near the bottom; Your valve or pump suction threads straight into the 3 inch female thread, or into the 2 inch reducer for a 2 inch line. Support the valve and the first length of pipe within a foot of the wall so the fitting carries liquid, not hardware.
2. Manway. A 22 inch threaded vented manway on top. Leave the vent clear so air can move as the level changes, and keep the lid on; an opening this size is a fall hazard for a child or an animal.
3. Extra ports. Only the one outlet comes installed. A recirculation return, a second draw or an overflow means extra bulkhead fittings; tell us when you order and we put them on the same order as the tank.
4. Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the outlet position, the manway and the base profile.

Shipping and receiving

The tank ships LTL at freight class 400 from Norwesco's Fairfield, Texas plant as a 142 by 142 by 89 inch load weighing 969 lb. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. At the tailgate, check the part number against 44824 on the bill of lading, look over the base, the outlet fitting and the siphon tube for transit damage, and fill with water the first time before the tank carries anything else.
