The Snyder Industries 10500 Gallon HDPE Vertical Chemical Storage Tank is a bulk-scale white tank built for serious chemical service, rated to 1.9 specific gravity in high density linear polyethylene (HDLPE). At 169 inches tall on a 142 by 142 inch footprint, this is a fixed-site vertical storage tank sized for water treatment plants, industrial process chemical farms, and high-volume bulk handling where 10,500 gallon rated capacity is the baseline. The 1.9 SG rating is the number that matters here: it tells you the wall thickness and resin density were engineered to hold dense chemistries, not just water.
Will it work for your application?
Capacity is 10,500 gallons in a single vertical HDPE tank measuring 169 in high by 142 in diameter. Plan your slab and anchoring around the contents weight, not the empty shell. Filled with water at 1.0 SG the tank carries about 87,570 lb; at its full 1.9 SG rating the maximum contents weight reaches 166,383 lb. That is over 83 tons sitting on a 142-inch circle, so your foundation, ring wall, and seismic restraint have to be designed by an engineer to those loads before the tank arrives. The 1.9 SG rating is also a hard ceiling: if your chemistry exceeds 1.9 specific gravity, this tank is not rated for it - call 866-418-1777 before ordering. Confirm your fill chemistry's specific gravity stays at or below 1.9, and confirm the actual filled weight against your site's bearing capacity. Use the Tank Sizing Calculator and Tank Sizing Guide to match this vertical storage tank to your throughput and headspace requirements.
Chemical compatibility
This tank is molded in high density linear polyethylene (HDLPE) and rated to 1.9 specific gravity, which puts a wide range of concentrated water-treatment and industrial chemistries within reach. Match the tank to your fill against the OEM chemical-resistance chart, which is concentration- and temperature-specific. The chemistries below are confirmed compatible at the listed concentrations, each paired with the fitting and gasket materials you should specify. Note that bulkhead fittings and gaskets are specified and ordered separately to suit your fill - they are not included with the tank, so build your fitting and elastomer kit from the materials called out below:
- Acetic Acid 60% - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate 50% - PVC fittings, EPDM gaskets
- Calcium Chloride 40% - PVC fittings, EPDM gaskets
- DEF (diesel exhaust fluid) 32.5% - 316SS fittings, EPDM gaskets
- Ethylene Glycol 100% - PVC fittings, EPDM gaskets
- Ferric Chloride 50% - PVC fittings, EPDM gaskets
- Ferric Sulfate 60% - PVC fittings, EPDM gaskets
- Ferrous Sulfate 20% - PVC fittings, EPDM gaskets
- Hydrochloric Acid 37% - PVC fittings, Viton gaskets
- Hydrofluoric Acid 48% - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid 26% - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide 50% - PVC fittings, Viton gaskets
- Magnesium Chloride 30% - PVC fittings, EPDM gaskets
- Peracetic Acid 30% - 316SS fittings, Aflas gaskets
- Phosphoric Acid 85% - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate 50% - PVC fittings, EPDM gaskets
- Potassium Hydroxide saturated - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Carbonate 30% - PVC fittings, EPDM gaskets
- Sodium Hypochlorite below 16.5% - PVC fittings, Viton gaskets
- Sodium Thiosulfate 40% - PVC fittings, EPDM gaskets
- Sulfuric Acid 98% - CPVC fittings, Viton gaskets
- Urea Solution 50% - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water up to 10 PPM - PVC fittings, EPDM gaskets
Notice the gasket material changes with the chemistry: EPDM for most salts and bases, Viton for the strong acids and oxidizers like sulfuric, hydrochloric, hydrogen peroxide, and sodium hypochlorite, and Aflas for peracetic acid. The single most common mistake on a tank this size is specifying the wrong elastomer at the fitting and then chasing a slow weep for months. Match every gasket and fitting to your specific fill, and verify your exact concentration and operating temperature against the manufacturer's chemical-resistance chart before you commit.

Specifying the outlets and instrumentation
On a 166,000 lb chemical tank, the bulkhead fittings, level instrumentation, and labeling are not afterthoughts. Get the level-measurement technology right for your chemistry with our guide to tank level gauge selection for chemical service, and plan secondary containment up front - compare approaches in Snyder Captor Plus 110% containment vs UL-142 and SPCC. Before the tank goes into service, square away your tank label and signage compliance and a repeatable chemical sampling protocol so your lab results are representative from day one. Dimensions and port layout are on the technical drawing on this page.
This Snyder vertical storage tank ships LTL freight, quoted live to your ZIP from the nearest stocking plant - Lincoln, NE or Philippi, WV. The empty 10,500-gallon tank moves as a single oversize LTL piece, and which of those two plants is closest can swing your rate materially by region, so enter your ZIP early to see the real number. Get your quote with our Freight Cost Estimator or call 866-418-1777 and we will route it from the closest plant to hold your freight down. List price shown is before freight.
