Notes from the vendor documentation
Day-tank secondary containment commonly used at wastewater plants; not wastewater-specific in source.

Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Captor Double Wall Tank material | High Density Linear Polyethylene (HDLPE); crosslinked linear polyethylene available by request; 110-120% containment, fully enclosed | Snyder Industries — Double Wall Tanks |
| Captor size range | 35-8,700 gal sampled (23 real sizes) on the current spec table, up to a 12,500 gal confirmed ceiling on an earlier read | Snyder Industries — Double Wall Tanks |
| Max material weight / SG limit | 15.83 lb/gal max material weight (1.9 specific gravity rating); tank cannot be pressurized | Snyder Industries — Double Wall Tanks |
| DCT Systems size range | 35-1,500 gallons, marketed for commercial "Day" tank secondary containment applications | Snyder Industries — Double Wall Tanks |
| Regulatory compliance | Complies with FDA Regulation 177.1520, NSF/ANSI 61, and 40 CFR 264.193 secondary-containment capacity requirements | Snyder Industries — Double Wall Tanks |
The Captor/DCT line cannot be pressurized — specifying it into any application with even incidental positive pressure is a design error the tank itself won't survive.
40 CFR 264.193 secondary-containment capacity is a compliance floor at wastewater plants handling hazardous chemical feed, not a suggestion — the Captor's 110-120% containment and its documented NSF/ANSI 61 and FDA 177.1520 compliance are what let a dual containment spec pass an inspection instead of just looking like one.
