12,000-gallon black liquid storage tank built for agricultural chemical and fertilizer storage. Manufactured by Snyder Industries from high-density linear polyethylene (HDLPE) rated to handle liquids up to 11.3 pounds per gallon. UV-resistant black pigmentation provides maximum outdoor durability and inhibits algae growth in stored liquids.
The 12000 GALLON ASTM 1.35 SG IN BLACK is designed for municipal water systems, large-scale agricultural operations, and industrial facilities requiring bulk storage capacity. At 12,000 gallons, this is a facility-scale tank built for operations that measure liquid consumption in thousands of gallons per day. It is the anchor of agricultural chemical and fertilizer storage systems for municipalities, large farms, and industrial plants.
Constructed from high-density linear polyethylene (HDLPE) using a single-piece rotational molding process that eliminates seams, weld lines, and potential leak points. Rated to 1.35 specific gravity, this tank handles liquids up to 11.3 pounds per gallon — covering the full range of agricultural chemicals, liquid fertilizers, and most industrial solutions. The wall thickness is engineered specifically for this density range. UV-resistant black pigmentation provides maximum outdoor durability and inhibits algae growth in stored liquids. Maximum operating temperature is 120 F/ 48 C, with UV stabilizers compounded directly into the resin for outdoor service life.
This tank measures 198 inches tall with a 142-inch diameter, requiring 110.0 square feet of level ground. Empty weight is 3100 pounds. At full capacity with a 1.35 SG liquid, expect approximately 138,208 pounds on the foundation. Requires an engineered reinforced concrete foundation designed by a structural professional for the full loaded weight. Large tanks require professional installation. Ensure the pad is level within 1 inch across the full diameter and that all piping connections allow for thermal expansion.
Comes equipped with a 3 NPT outlet fitting installed at the factory. No inlet fitting is included — drill and install a bulkhead fitting at your preferred height for your specific plumbing layout. The 18" lid opening provides ample access for interior inspection, cleaning, and installation of float switches, level sensors, or submersible pumps. Install schedule 80 PVC or stainless steel piping on all 3" NPT connections. Full-port ball valves, expansion loops for thermal movement, and proper pipe support are essential at this scale.
