The Chem-Tainer 165 Gallon Vertical Storage Tank (SKU TC3158IC-BLACK) is a black polyethylene vertical tank built for straightforward water and non-hazardous liquid storage. It stands 58 inches tall on a compact 31 x 31 inch footprint, so it fits tight utility rooms, well houses, and equipment pads where floor space is limited but you still need real capacity. At 165 gallons, this vertical storage tank slots in as a right-sized choice for pressure-boost buffering, irrigation supply, hauled-water holding, and general bulk storage.
Will it work for your job?
This is a polyethylene vertical tank with a specific gravity rating of 1.5, meaning it is engineered to hold contents up to 1.5 times the weight of water. Filled with plain water, the tank carries about 1,376 pounds; at its full 1.5 SG rating it is built to support up to 2,064 pounds of contents across the 165-gallon volume - roughly 12.5 pounds per gallon versus 8.34 for water. Before you order, check your actual liquid's specific gravity against that 1.5 ceiling: 1.5 SG is this tank's limit, and anything heavier than 1.5 times water requires a different, higher-rated tank. Use the Tank Sizing Calculator and our Tank Sizing Guide to confirm this size matches your draw-down and refill cycle.
Getting the setup right
A flat, fully supporting, level base under the entire 31 x 31 inch footprint is essential - a point-loaded or partially supported bottom is the most common cause of premature tank failure. On a footprint this narrow relative to the 58-inch height, a stable and level foundation is non-negotiable; review our guidance on concrete pad sizing for above-ground polyethylene tanks to size the base correctly. Confirm the 58-inch height against your overhead plumbing runs and available headroom before installation. Outlet and fitting configuration is not fixed in this listing - call 866-418-1777 to confirm the bulkhead, outlet, and any fitting details you need before ordering so the tank arrives plumbed the way your job requires.
