The Enduraplas 550 Gallon Plastic Vertical Water Storage Tank (SKU TLV00550) is a straight-wall polyethylene vertical tank built for water storage. It measures 52 inches tall on a 60-by-60-inch footprint and holds 550 gallons, per the verified launch spec. The technical drawing on this page shows the vertical profile, the fitting layout, and the lid position, so you can confirm the tank fits your pad and plumbing before you order.
Will it work for your site
Filled to 550 gallons, this tank carries roughly 4,587 pounds of water, and that full-water weight is the number your pad has to carry - not the empty shell weight. Plan the base around it. The 60-by-60-inch footprint spreads that load over a full five-by-five-foot square, which keeps bearing pressure reasonable on a proper slab. If you are sizing the pad from scratch, our concrete pad sizing guide walks the ACI framework, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 550 gallons is the right reserve for your draw rate. This is a common vertical water storage tank size for rural water haul, fire reserve, irrigation buffering, and rainwater or water-reuse aggregation.
Fittings and setup
The drawing shows one 2-inch threaded outlet for your fill or draw plumbing and a 16-inch lid for filling, inspection, and cleanout access. Match your bulkhead fitting, gasket, and any valve or camlock to that 2-inch thread, and seat the gasket properly before you torque the connection. After install, run a water-fill acceptance check before the tank goes into service - our hydrostatic test methodology covers fill discipline, pad settlement monitoring, and leak detection at the fittings.
The mistake to avoid
This is a water storage tank. If you are considering it for anything heavier than water - a fertilizer, brine, or any solution with a specific gravity above 1.0 - stop and confirm the tank's specific-gravity rating first, because that rating is not published on this listing. For fire-water reserve service, size to your standard before you buy; our NFPA 22 reservoir design guide and water-reuse topology guide cover the two most common applications for a tank this size.
