The Norwesco 100 Gallon Ribbed Pest Control Operator (PCO) tank in white is built for technicians running liquid-application routes who need a compact, rugged supply tank that fits in a truck bed, on a skid, or behind an ATV. Molded from polyethylene with a ribbed sidewall for structural rigidity, this 100 gallon tank carries a 30 x 38 inch footprint, so it tucks into a tight equipment layout without giving up capacity. What separates it from a plain water tank is the 1.5 specific gravity rating: it is engineered to hold heavier-than-water liquids, which is exactly what a PCO tank needs to do.
Will this Norwesco PCO tank work for your application
Filled with water (SG 1.0), this tank holds about 834 pounds of contents. Because the polyethylene wall is rated to 1.5 specific gravity, it is approved to carry up to roughly 1,251 pounds at full volume when you run a denser liquid than water. That is 417 pounds of headroom for the formulated PCO concentrates, surfactants, and mixed products that run heavier than plain water. To confirm you stay inside that ceiling, take your finished solution's weight per gallon and multiply by the volume you actually fill, then check it against the 1,251 pound limit. Size the rig itself with the Tank Sizing Calculator and the Tank Sizing Guide before you commit a bed, trailer, or pad slot to it.
One mistake to avoid
The most common error with a 100 gallon PCO tank is treating the 1.5 specific gravity number as a capability rather than a ceiling. It is the maximum density the wall is built to support at full volume; it does not mean every chemical is safe in the tank. If your mix runs heavier than 1.5 SG, that is the signal to step up to a higher-SG-rated tank rather than overfilling this one. Always confirm your specific product's chemistry and concentration against the manufacturer's chemical-resistance data, and spec the gasket material to that liquid: EPDM, Viton, and Buna each suit different chemistries, so the gasket has to match the product you carry. This tank's fitting configuration is shown on the technical drawing on this page rather than assumed-included, so confirm bulkhead and outlet size and gasket material there before ordering.
Footing and freight
A 30 x 38 inch footprint needs continuous, flat, full-bottom support. Polyethylene tanks are not designed to bridge gaps or sit on rails, so a properly sized pad or deck under the entire base is part of doing this right; see the concrete pad sizing guide if you are setting this on a fixed pad. Refer to the technical drawing on this page to confirm dimensions and fitting locations against your equipment before you order.
