Interesting Halachic update on this topic for Sephardim:
According to the Yalkut Yosef (Siman 4, Halacha 1): If one does not have a “kli” to wash negelvasser with, he should use the faucet, turning it on and off each time. He should NOT say the bracha of al netilas yadayim.
This is unlike the Mishna Berurah who says that you do in fact make a bracha in this case.
Since you are Sephardi, LB, it might be a problem for you to make a bracha in such a situation.
