The Snyder Industries 4500 Gallon HDPE Vertical Liquid Storage Tank is a white polyethylene vertical storage tank built for high-volume water and liquid storage where a large, stable footprint matters. It stands 142 inches tall on a 102 x 102 inch base, holding 4,500 gallons nominal in a single vertical column. The tank carries an ASTM specification rating and a 1.5 specific gravity rating, meaning the wall is sized to safely hold liquids up to 1.5 times the weight of water.
Does it work for your site?
Start with weight, because that governs your pad more than the tank itself does. Filled with water, this vertical tank puts roughly 37,530 pounds on the ground; at its full 1.5 SG rating the contents alone can reach 56,295 pounds. That load rides on a 102 x 102 inch footprint, so the concrete pad and subgrade under it have to be engineered for the point load, not just the tank diameter. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm 4,500 gallons matches your draw and refill cycle, then review our guide on concrete pad sizing for above-ground polyethylene tanks before you pour. If this feeds a rural fire-protection reservoir, our NFPA 22 fire-water reservoir design guide covers sizing discipline and freeze protection for cold-climate HDPE storage.
The mistake to avoid
The specific gravity rating is where large vertical storage tanks get people. A 1.5 SG rating means the wall is sized for dense liquids, but that rating assumes the wall is intact everywhere. Premature failures on tall polyethylene tanks tend to start at the vapor-saturated headspace near the top, not on the liquid side where inspections usually focus. Read our breakdown of HDPE tank wall thickness at the vapor-saturated headspace and the ASTM D1998 sizing logic before you commit to a service liquid. Confirm the outlet, fitting, and manway layout against the technical drawing on this page before you order plumbing. If you are aggregating grey-water, rainwater, or HVAC condensate for reuse, our industrial water reuse tank topology guide covers quality-banded storage trains.
Freight
At 142 inches tall and up to roughly 56,300 pounds loaded, this is a large-format vertical tank that ships LTL freight, quoted live to your ZIP. Verify overhead clearance and offload capacity at your site before delivery day. It is stocked at Snyder plants in Chowchilla, CA and Lincoln, NE, and we route from whichever is nearest to hold your freight cost and transit time down. Get a real number in seconds with our Freight Cost Estimator, or call 866-418-1777 and we will quote the tank and freight to your delivery address together. Freight is quoted separately from the tank list price.
