The Bushman 4050 Gallon Vertical Water Storage Tank in Mocha is a polyethylene bulk-storage tank built for large-volume water service - rainwater harvesting, rural fire reserve, irrigation supply, and grey-water or rainwater reuse trains. It measures 101 inches in diameter and 129 inches tall, holds 4,050 gallons on a compact 101 x 101-inch footprint, and ships from Bushman's Temecula, California plant. The tank carries a 1.0 specific-gravity rating, which is the spec to read first: it is rated for water and water-density liquids, not heavier solutions.
Will it work for your site?
This is a vertical water storage tank in the truest sense - a tall column of capacity that fits a 101 x 101-inch pad while delivering 4,050 gallons. Filled to capacity with water, the contents weigh 33,777 pounds, which is also the maximum rated contents weight at the 1.0 specific-gravity rating. That figure is the filled load for pad engineering, not the shipping weight - the tank ships empty. A full 4050 carries nearly 17 tons of water, so the pad has to be engineered for it. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the gallons match your draw and refill cycle, and read our guide on concrete pad sizing for above-ground polyethylene tanks before you pour - it walks the ACI 360R-10 framework for a tank this heavy.
Fittings and configuration
The tank comes with a vented manway up top and a 2-inch bulkhead fitting for the outlet. Knowing the outlet is 2-inch lets you pre-size your valve, bulkhead gasket, and pipe run before delivery instead of discovering it on site - see the technical drawing on this page for the exact placement of the manway and outlet so you can plan plumbing and overflow runs. The vented manway matters on a sealed vertical: as you draw water down, the tank needs to breathe, and a vented top prevents the vacuum that can deform a poly wall. If you are tying this into a harvesting system, our guide on Bushman rainwater harvesting and first-flush diverter sizing covers the inlet side, and the industrial water reuse topology guide helps if this tank is one stage in a banded reuse train.
The mistake to avoid
The 1.0 specific-gravity rating is the line not to cross. This tank is built for water, which has a specific gravity of 1.0; pushing a denser liquid into it puts load on the wall the tank was never rated to carry. If your service is anything beyond water density, that is a different tank - call 866-418-1777 and we will spec the correctly rated vessel rather than overload this one. For fire-reserve duty, the gallons-on-hand and refill discipline matter as much as the vessel - our fire-water reservoir design guide works through NFPA 22 sizing and cold-climate freeze protection for a poly tank in this role.
This 4050 ships empty on LTL freight from a single West Coast origin - Bushman's Temecula, California plant - quoted live to your ZIP. East Coast and Midwest buyers should plan for the cross-country haul; get a real number for your delivery with the Freight Cost Estimator, or call 866-418-1777 to talk through your install, pad, and plumbing before you order. We will line up the tank, the fittings, and the freight so it lands ready to set.
