Cone Bottom Tanks
100% Drainage. Zero Residue.
Choose cone bottoms when complete drain-out is critical — like sodium hypochlorite or sludge-heavy wastewater. A James Riggins–spec'd system dials in cone angle, resin, stand, and fittings so you avoid sludge, cleanouts, and fines — and get a 20+ year life.

Cone bottom tanks require a correctly engineered cone angle, drain outlet (e.g., IMFO®), and factory stand. Get one wrong and you'll see residue buildup, stress cracking, or even a voided warranty. James' approach: specify the right angle (15°/30°/45°), resin (HDPE/XLPE/PP), outlet, and the approved stand — then integrate containment and controls so operators get clean batches and long service life.

Frequently Asked Questions
When should I choose a cone bottom tank over a flat bottom tank?
Choose cone bottoms when complete drain-out is critical — such as sodium hypochlorite service or sludge-heavy wastewater — since the angled bottom eliminates residue that a flat bottom tank would retain.
What cone angles are available and how do I pick one?
Common angles are 15°, 30°, and 45°, matched to the solids or sludge content of the stored material — steeper angles drain more aggressively but require more vertical clearance.
Can I use any stand under a cone bottom tank?
No — many cone bottom tanks, especially Snyder models, require a factory-engineered stand. Using a non-approved stand can void the warranty and lead to structural failure.
