350 Gallon Water Tank - W-Series

High Country Plastics 350 Gallon W-Series Water Tank (W-350)

Provide your horses, cattle, and farm livestock with a generous, dependable water supply using the High Country Plastics 350 Gallon W-Series Stock Tank. Engineered for demanding pasture environments and high-traffic watering areas, this 350-gallon round trough is rotationally molded from FDA-approved, high-impact linear polyethylene infused with UV inhibitors to prevent sun degradation, cracking, and weathering.

Unlike two-piece or plastic-welded stock tanks that can split under pressure or freeze-thaw cycles, the W-350 features a true seamless, one-piece design. This ensures uniform wall thickness and exceptional durability throughout the entire structure. All top rims and outer lip edges are completely rounded to keep animals safe from cuts or scrapes during drinking.

For easy maintenance, the tank comes equipped with a molded-in 1-1/4" FNPT aluminum drain insert. This permanent fitting guarantees a leak-proof seal that will not rust, sun-rot, or break down over time. The included removable poly drain plug can easily be swapped out with a standard float valve for automatic filling or paired with a tank heater for winter freeze protection.

Key Features:

• 350-Gallon Capacity: Broad round footprint provides ample water volume for multiple animals at once.

• Seamless One-Piece Construction: Rotationally molded from FDA-approved, food-grade polyethylene to eliminate seam leaks and weak points.

• Animal-Safe Rounded Edges: Smooth, rounded top lip protects cattle, horses, and small stock from injuries while crowding around the tank.

• Molded-In Aluminum Drain Insert: 1-1/4" FNPT aluminum fitting provides a permanent, leak-proof drain seal that will never rust or sun-rot.

• Float Valve & De-Icer Compatible: Drain insert easily accommodates automatic pressure valves or winter stock tank heaters.

• Field-Repairable: Unique poly formulation allows minor punctures or leaks to be braze-welded with a standard butane torch.

• 5-Year Manufacturer Warranty: Backed by High Country Plastics' 100% 5-year limited warranty from the date of purchase.
