The Enduraplas 150 Gallon Black Vertical Water Storage Tank (SKU TLV00150B) is a compact vertical water tank built for bulk water storage, holding 150 gallons in a 30-inch diameter, 61-inch tall body. Molded from polyethylene in black to slow algae growth by blocking sunlight, it carries a 1.1 specific gravity rating - meaning it is engineered for water and water-like fluids up to that density. If you are sizing a vertical storage tank for a tight equipment pad, well line, irrigation feed, or a fire-water reserve, this is a straightforward 150 gallon unit on a genuinely small 30-inch circular base.
Will it work for your site?
Start with the load. Filled with water, this tank carries roughly 1,251 pounds of contents; at its full 1.1 SG rating it is rated to hold up to 1,376 pounds - so water leaves about 125 pounds of density reserve before the ceiling. That weight sits on a 30-inch diameter footprint, so the pad or floor beneath it takes a concentrated, circular load - plan the base accordingly. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks so you build a base that will not settle unevenly. The 61-inch height gives you gravity head for downstream feed while staying low enough to fill and inspect without special access. Contact us to confirm exact fitting locations and sizes before you plumb the inlet and outlet.
Sizing and commissioning
If you are still deciding between 150 gallons and a larger vertical storage tank, run your daily draw through the Tank Sizing Calculator and cross-check it against the Tank Sizing Guide - a black water storage tank in this size class is popular for rural fire-water reserves and reuse trains where footprint matters more than volume. For fire-protection duty, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. Once the tank is set, commission it right: our hydrostatic test methodology covers water-fill discipline, pad-settlement monitoring, and fitting leak-detection for new-install acceptance.
The mistake to avoid
Do not push this tank past what its 1.1 specific gravity rating allows. That number sets the maximum fluid density it is built to hold - water sits at 1.0, so you have a modest ~125-pound margin, but a heavier liquid can blow past the 1,376-pound contents ceiling and stress the wall. Keep it in water and water-like service. If you plan to aggregate grey-water, rainwater, or HVAC condensate, the industrial water reuse topology guide shows how a tank this size fits a quality-banded storage train.
