3000 Gallon Plastic Vertical Water Storage Tank

The Enduraplas TLV03000 is a 3,060-gallon vertical water storage tank built for bulk water, irrigation, fire-reserve, and water-reuse holding where you need real volume in a compact round footprint. Every number below comes from this tank's own spec sheet and technical drawing:

• Capacity: 3,060 gallons
• Dimensions: 125 in tall on a 90 in diameter
• Footprint: 90 x 90 in
• Full water weight: 25,520 lb
• Fittings (per drawing): 16 in lid, 3 in threaded fitting, 2 in threaded fitting

Will this tank do the job?

Rated capacity is 3,060 gallons in a vertical storage configuration standing 125 inches high on a 90-inch diameter — a tall column of water that holds real volume without sprawling across a yard. The drawing shows a 16-inch lid for fill and inspection, a 3-inch threaded fitting, and a 2-inch threaded fitting; see the technical drawing on this page for placement before you plumb. Match your adapters to those exact ports — a 3-inch bulkhead or poly nipple with gasket for the 3-inch port, and a matching 2-inch fitting with gasket for the 2-inch port — so thread sizes seat cleanly and seal. The 16-inch lid is also your access point for the fill and inspection work, and for the hydrostatic hold-test and settlement checks below. This spec sheet does not list a specific-gravity rating, so keep this tank to water and water-reuse service; if you are considering anything heavier than water, confirm the SG rating first at 866-418-1777 before you commission the line.

Foundation and fire-reserve service

Filled with water this tank carries 25,520 pounds, so the pad underneath it matters as much as the tank. A flat, level, fully-supporting concrete pad sized to the full 90 x 90 inch footprint is the right foundation; our pad-sizing guide walks the ACI framework, and if you are still confirming volume against draw-down and refill rates, run the Tank Sizing Calculator alongside the Tank Sizing Guide. The compact vertical form makes this a common choice for private fire-protection reservoirs and industrial water-reuse trains. If you are sizing rural fire-water storage to NFPA 22, our fire-water reservoir design guide covers the sizing discipline and cold-climate freeze protection. For grey-water, rainwater, and HVAC condensate aggregation, the water-reuse topology guide shows where a bulk vertical tank fits in a quality-banded storage train.

The mistake to avoid on a tank this size

The biggest error with a 25,520-pound full load is trusting an under-built or uneven base. A threaded fitting seals and holds only when the tank sits flat and fully supported — any settlement or high spot puts point load on the wall and the fitting. Set the pad, level it, then fill and hold-test through the 16-inch lid before you commission the line; our hydrostatic test guide lays out the water-fill discipline, settlement monitoring, and hold-time math for new-install acceptance. One more honest note: color and opacity are not specified on this sheet, so if UV exposure or opacity matters for your outdoor install, confirm available colors at 866-418-1777.
