For an all-in-one trough system, complete with water storage & drinking trough then look no further than West Coast Poly’s Tank & Donut Troughs. Made In WA, West Coast Poly worked closely with WA farmers when designing this system, resulting in a clever design that gives you the best of durability and practicality. The tank & trough separate easily, are light enough to be moved to a different paddock, making them ideal for rotational grazing. Whether it be 1 sheep, 2 sheep, or a flock of sheep, our automatic waterflow system keeps a steady flow of water to your trough that can keep up with the entire flock.
