12000 Gallon Plastic Water Storage Tank

What 12000 gallons is for

Fire water for a remote facility, process and wash water for a plant, irrigation or stock water for a large operation, and the storage tank in a commercial rainwater or reuse system are the jobs this size does. The fire water reservoir design guide covers the volumes fire authorities look for, the draft connection and keeping a big tank liquid through winter; the water reuse storage guide covers where bulk storage sits in a reuse train. At 193 inches, sixteen feet, the top is a fixed ladder job and the empty tank catches wind, so strap it until the first fill. The 141 inch circle must sit on a flat, level, continuous engineered slab carrying 100,080 lb of water plus the tank; the concrete pad sizing guide gives the framework and at this load an engineer should size and sign the pad. Where the supply cannot be interrupted, two tanks with a crossover beat one, because one can be drained and cleaned while the other serves. The tank sizing calculator and the tank sizing guide help with the volume; the permit and site questions belong to you and your engineer.

Openings and fittings

1. Outlet. A 3 inch polypropylene female NPT bulkhead fitting low in the wall, sized for the flow a tank this big is expected to deliver. For a fire draft connection, tell us what the department wants to see and we will confirm it before the tank ships. Support the valve and the pipe on their own.
2. Inlet and top opening. No separate inlet fitting or top manway is listed on this page. Tell us how you plan to fill, vent and inspect the tank and we will confirm the top openings and the fill arrangement in writing before you order.
3. 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.
4. Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the outlet height and the top layout; read it before the slab is poured so the outlet faces the pipe run.

Shipping and receiving

The tank travels on its side, 193 by 141 by 141 inches, as an oversize load on a flatbed at freight class OVS, from whichever of Norwesco's Fairfield, Texas or Hanford, California plants is nearer to you. It is a permitted wide load on most lanes, so allow lead time, 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, and a written quote is the normal route for a job this size. Standing it up takes a crane or a large telehandler and a rigging plan with slings that spread the load; arrange that before the truck is booked. At the tailgate, check the part number against 44810 on the bill of lading, walk the shell for transit damage, stand it on the slab, and run the water fill acceptance test, watching the pad for settlement as it fills, before it carries anything else.
