The Enduraplas 1350 Gallon Plastic Vertical Water Storage Tank (SKU TLV01350) is a low-profile vertical polyethylene tank built for bulk water: irrigation buffering, rainwater and reuse collection, fire-reserve holding, and general above-ground bulk water storage. It is squat rather than columnar - 75 inches tall on a base 85 inches across - so it holds 1,350 gallons while fitting under low eaves, inside pole barns, and beneath overhead runs where a taller tank would not clear. Verified dimensions and the fitting layout are shown on the technical drawing on this page, so you can confirm clearances and plumbing runs before the tank arrives.
Will it work for your site
This is a self-supporting vertical tank that carries its full load on the base, so it needs a level, fully supporting pad. The base is circular at 85 inches in diameter and occupies an 85 x 85 inch square envelope, so lay out your pad to that square. Plan for the loaded weight, not the empty shell: 1,350 gallons of water weighs about 11,259 pounds full, and that mass sits on the 85-inch base. Size your slab accordingly with our Tank Sizing Calculator and Tank Sizing Guide, and if you are pouring new, the concrete pad sizing framework for above-ground polyethylene tanks walks through the ACI 360R-10 approach.
Fittings and configuration
The technical drawing shows a 16 inch lid for access and inspection and one 2 inch threaded fitting for your fill or draw line. Confirm both against the drawing before you commit your manifold layout. Any additional bulkhead fittings or gaskets are a separate line item and are not included in the base tank - call 866-418-1777 and we will spec fitting and gasket compatibility for your plumbing rather than leaving you to guess. Color and translucency are not listed for this SKU, so if opaque or translucent matters for algae control or fire-reserve service, confirm availability with us at order.
Fitting it into a system
At 1,350 gallons this size sits in the range for rural fire-water reserves, irrigation day-tanks, and water-reuse trains. If this tank is part of a private fire-protection stack, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate aggregation, the water reuse topology guide shows how storage like this fits a quality-banded train. This SKU is sold as a water tank; a specific-gravity rating is not published for it, so for any fluid heavier than water confirm the rating by phone before ordering.
The mistake to avoid
The most common error on a vertical bulk water tank this size is commissioning it without a proper acceptance fill. Before you rely on it, run a staged hydrostatic fill and hold, watch the pad for settlement, and check the 16 inch lid and 2 inch threaded fitting for weeps under head pressure. The hydrostatic test methodology guide lays out the water-fill discipline, settlement monitoring, and hold-time math. Catching an unlevel pad or a loose fitting on the first fill is far cheaper than discovering it under a full 11,259-pound load.
