The Norwesco 10000 Gallon 15 Degree Vertical Cone Bottom Tank is a full-drain industrial vessel molded in high density linear polyethylene (HDLPE), rated to a 1.9 specific gravity so it can hold dense chemical solutions that would exceed a standard 1.5 SG water tank. The tank stands 173 inches tall on a 142 x 142 inch footprint, and the 15-degree cone bottom drives complete gravity drainage and sediment removal - the reason buyers search for a cone bottom tank or vertical HDPE cone tank in the first place. Like every cone-bottom design, it must sit in a matching steel stand or hopper structure; the cone is not self-supporting on a flat slab.
Will it work for your application?
Usable capacity is 10,000 gallons. Size your structure and pad around the loaded weight, not the empty shell: filled with water this tank carries roughly 83,400 lb, and at its maximum rated contents weight - dense chemical at the full 1.9 SG - it reaches about 158,460 lb. That total load drives your stand rating, anchor design, and foundation. The 142-inch round footprint and 173-inch height also set your door clearances and rigging height at the install site. Run the numbers with the Tank Sizing Calculator and the Tank Sizing Guide to confirm volume and weight against your process before you commit, and see the technical drawing on this page for fitting locations and overall dimensions.
Chemical compatibility
This is an HDLPE shell rated to 1.9 specific gravity, which is what lets it handle the denser acids and concentrated solutions below. The compatibility data here comes from the OEM chemical-resistance chart, which is concentration- and temperature-specific - match your exact concentration and operating temperature to the chart, and click any chemical below for its per-chemical limits. The chemical table lists the recommended fitting and gasket material for each service; fittings are selected and quoted to your chemical, not pre-installed, and their locations are shown on the technical drawing on this page. If you have a question about resin choice or temperature for an aggressive oxidizer, call 866-418-1777 before you order.
Verified compatible services and their recommended fitting and gasket materials include Acetic Acid (60%, PP/PVC, EPDM), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Magnesium Chloride (30%, PVC, EPDM), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Thiosulfate (40%, PVC, EPDM), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM).
The most aggressive services need Viton or CPVC at the seals rather than EPDM - the single most common mistake on a chem tank is fitting EPDM-gasketed PVC across the board. Match these to the chart specifically:
- Hydrochloric Acid (37%, PVC, Viton)
- Hydrofluoric Acid (48%, PP/PVC, Viton)
- Hydrofluosilicic Acid (26%, PP/PVC, Viton)
- Hydrogen Peroxide (50%, PVC, Viton)
- Phosphoric Acid (85%, PVC, Viton)
- Sodium Hypochlorite (under 16.5%, PVC, Viton)
- Sulfuric Acid (98%, CPVC, Viton)
- Peracetic Acid (30%, 316SS, Aflas)

Freight and ordering
This tank ships LTL freight, quoted live to your ZIP from the nearest Norwesco plant - either Fairfield, TX or St. Bonifacius, MN. A 10,000-gallon cone tank is an oversized load, so freight is meaningful: get your number before you commit by running your ZIP through the Freight Cost Estimator. For help matching the cone angle, stand, and process, read the Norwesco Cone Bottom Tank Buyer's Guide, the 10,000 Gallon Cone Bottom Tank guide, and the Cone Bottom Tank Stand Compatibility Matrix.
