Horse stock tanks provide water to horses where water isn't found naturally. Stock tanks are constructed in ether galvanized metal or polyethylene. Galvanized metal stock tanks are corrosion resistant and tough enough to last for years. Polyethylene stock tanks are corrosion resistant and light weight (when empty) for easy relocation. See our full line of water pumps for transferring water from portable tanks to your stock tank. Water flowing into the bottomless stock tank from a windmill or solar powered pump allows fresh water to be replenished continuously.
